/run-plan <plan-file> [phase|finish] [auto] [every SCHEDULE] [now] | stop | next — Plan Phase Executor

Orchestrates plan-driven development. Reads a plan document, identifies the next incomplete phase, dispatches implementation in a worktree, verifies with a separate agent, updates progress tracking, writes a persistent report, and optionally auto-lands to main. Can self-schedule for recurring runs to work through multi-phase plans autonomously.

Ultrathink throughout. Use careful, thorough reasoning at every step.

Arguments

/run-plan <plan-file> [phase] [auto] [pr|direct] [every SCHEDULE] [now]
/run-plan stop | next
  • plan-file (required) — path to plan, e.g. plans/FEATURE_PLAN.md
  • phase (optional) — specific phase, e.g. 4a. If omitted, auto-detect next incomplete phase
  • finish (optional) — run ALL remaining phases sequentially until the plan is complete. finish is approval to START — do not ask for confirmation before the first phase (the user already said "finish"). Without auto: pauses BETWEEN phases to show results and ask "continue to next phase?" With auto (or the finish auto composite alias): each phase runs as its own cron-fired top-level turn (~5 min between phases via one-shot crons scheduled by Phase 5c). The first phase runs immediately; each subsequent phase is scheduled after the prior phase lands. Preserves fresh context per phase — no late-phase fatigue. Each phase still gets full verification, testing, and all safety rails. If any phase fails verification or hits a conflict, stops there. finish and every are mutually exclusive. finish auto schedules its own ~5-min one-shot crons internally. every N schedules a recurring cron at user-set cadence. Combining them would produce two overlapping cron schedules. Use one or the other.
  • auto (optional) — run autonomously: skip scope-confirmation / approval prompts and human-review pauses (between-phase pause, drift findings, staleness check, verifier-fail review) so the skill can run without an attended user, AND pass --auto to per-phase /land-pr dispatches (auto-merge the resulting PR). The finish auto composite is an alias that hoists auto (backward-compat per D2-RP).
  • every SCHEDULE (optional) — self-schedule recurring runs via cron:
    • Accepts intervals: 4h, 2h, 30m, 12h
    • Accepts time-of-day: day at 9am, day at 14:00, weekday at 9am
    • Without now: schedules only, does NOT run immediately
    • With now: schedules AND runs immediately
    • Implies auto — scheduling only makes sense for autonomous runs
    • Cron prompt omits phase number so each invocation auto-detects the next incomplete phase
    • Each run re-registers the cron (self-perpetuating)
    • Cron is session-scoped — dies when the session dies
  • now (optional) — run immediately. When combined with every, runs immediately AND schedules. Without every, now is the default behavior.
  • status — show plan progress: all phases, their status, what's next, and what's blocked. Read-only — no agents dispatched, no approval gate.
  • stop — cancel any existing /run-plan cron and exit. Takes precedence over all other arguments.
  • next — check when the next scheduled run will fire. Takes precedence over all other arguments except stop.

Detection: scan $ARGUMENTS for:

  • stop (case-insensitive) — cancel cron and exit (highest precedence)
  • next (case-insensitive) — check schedule and exit
  • status (case-insensitive) — show plan progress and exit
  • finish (case-insensitive) — run all remaining phases sequentially
  • now (case-insensitive) — run immediately
  • auto (case-insensitive) — autonomous mode
  • every followed by a schedule expression — scheduling mode
  • pr (case-insensitive) — PR landing mode
  • direct (case-insensitive) — direct landing mode
  • Neither pr nor direct — read config default (execution.landing), or cherry-pick if no config

Landing mode resolution:

  1. Explicit argument wins: pr or direct in $ARGUMENTS
  2. Config default: read .claude/zskills-config.json execution.landing field
  3. Fallback: cherry-pick
# Detect landing mode
# Resolve repo root before any config read. $PROJECT_ROOT is never exported
# into a SKILL.md fence (it is only set inside post-run-invariants.sh, a
# separate process), so anchor it on $CLAUDE_PROJECT_DIR -- the established
# peer pattern used elsewhere in this skill (#791).

Finish-mode resolution. $FINISH_MODE is set deterministically from args (NOT orchestrator-tracked) so downstream conditionals (cherry-pick worktree gating, PR title construction, etc.) see a single canonical value. Values are exactly "finish", "finish-auto", or empty — nothing else is valid. Any downstream check that reads $FINISH_MODE must match against these three states.

# Detect finish mode (canonical values: "finish", "finish-auto", "")
FINISH_MODE=""
if [[ "$ARGUMENTS" =~ (^|[[:space:]])[fF][iI][nN][iI][sS][hH]($|[[:space:]]) ]]; then
  if [[ "$ARGUMENTS" =~ (^|[[:space:]])[aA][uU][tT][oO]($|[[:space:]]) ]]; then
    FINISH_MODE="finish-auto"
  else
    FINISH_MODE="finish"
  fi
fi

# AUTO_FLAG: set by standalone `auto` (regardless of finish), OR by the
# `finish auto` composite (backward-compatible alias per D2-RP).
AUTO_FLAG=0
if [[ "$ARGUMENTS" =~ (^|[[:space:]])[aA][uU][tT][oO]($|[[:space:]]) ]]; then
  AUTO_FLAG=1
fi

# Backward-compatible composite: `finish auto` implies AUTO_FLAG.
# The post-detection hoist preserves the load-bearing user workflow
# `/run-plan plan.md finish auto every 4h`.
if [ "$FINISH_MODE" = "finish-auto" ]; then
  AUTO_FLAG=1
fi

# AUTO_ARG: the suffix string to thread into every child-skill dispatch
# that recognizes positional `auto` (e.g. /refine-plan, /draft-plan,
# /draft-tests per #581 / PR #642). Empty when AUTO_FLAG=0 so children
# stay in non-auto behavior. Closure-incomplete #648 sites used this.
AUTO_ARG=""
if [ "$AUTO_FLAG" = "1" ]; then
  AUTO_ARG=" auto"
fi

Validation:

# direct + main_protected -> error
PROJECT_ROOT="${PROJECT_ROOT:-$CLAUDE_PROJECT_DIR}"
if [[ "$LANDING_MODE" == "direct" ]]; then
  CONFIG_FILE="$PROJECT_ROOT/.claude/zskills-config.json"
  if [ -f "$CONFIG_FILE" ]; then
    CONFIG_CONTENT=$(cat "$CONFIG_FILE")
    if [[ "$CONFIG_CONTENT" =~ \"main_protected\"[[:space:]]*:[[:space:]]*true ]]; then
      echo "ERROR: direct mode is incompatible with main_protected: true. Use pr mode or change config."
      exit 1
    fi
  fi
fi

Reading branch_prefix from config:

# Read branch prefix from config (default: feat/)
PROJECT_ROOT="${PROJECT_ROOT:-$CLAUDE_PROJECT_DIR}"
BRANCH_PREFIX="feat/"
if [ -f "$PROJECT_ROOT/.claude/zskills-config.json" ]; then
  CONFIG_CONTENT=$(cat "$PROJECT_ROOT/.claude/zskills-config.json")
  # ([^\"]*) allows empty string match -- empty prefix means no prefix

    BRANCH_PREFIX="${BASH_REMATCH[1]}"
  fi
fi

Resolving FULL_TEST_CMD from config:

The orchestrator resolves the test command ONCE here and passes it verbatim to every impl/verifier/fix-agent dispatch prompt. Three-case decision tree (same contract as /verify-changes):

PROJECT_ROOT="${PROJECT_ROOT:-$CLAUDE_PROJECT_DIR}"
FULL_TEST_CMD=""
if [ -f "$PROJECT_ROOT/.claude/zskills-config.json" ]; then
  CONFIG_CONTENT=$(cat "$PROJECT_ROOT/.claude/zskills-config.json")
  if [[ "$CONFIG_CONTENT" =~ \"full_cmd\"[[:space:]]*:[[:space:]]*\"([^\"]*)\" ]]; then
    FULL_TEST_CMD="${BASH_REMATCH[1]}"
  fi
fi

if [ -n "$FULL_TEST_CMD" ]; then
  # Case 1: config set — use it.
  TEST_MODE="config"
else
  # Check for test infra (same list as preflight hook-placeholder gate):
  # package.json with a "test" script, vitest/jest/pytest configs,
  # Makefile, tests/*.sh, tests/*.py, tests/*.js.
  TEST_INFRA_DETECTED=0
  [ -f "$PROJECT_ROOT/package.json" ] && grep -q '"test"[[:space:]]*:' "$PROJECT_ROOT/package.json" && TEST_INFRA_DETECTED=1
  ls "$PROJECT_ROOT"/vitest.config.* "$PROJECT_ROOT"/jest.config.* "$PROJECT_ROOT"/pytest.ini \
     "$PROJECT_ROOT"/.mocharc.* "$PROJECT_ROOT"/Makefile 2>/dev/null | grep -q . && TEST_INFRA_DETECTED=1
  ls "$PROJECT_ROOT/tests"/*.sh "$PROJECT_ROOT/tests"/*.py "$PROJECT_ROOT/tests"/*.js 2>/dev/null | grep -q . && TEST_INFRA_DETECTED=1

  if [ "$TEST_INFRA_DETECTED" -eq 1 ]; then
    # Case 2: tests exist but no command — misconfigured. Refuse.
    echo "ERROR: /run-plan: test infra detected but testing.full_cmd is empty." >&2
    echo "  Run /update-zskills to configure, or edit .claude/zskills-config.json." >&2
    exit 1
  else
    # Case 3: no test infra, no command — docs-only/greenfield. Skip test gate.
    TEST_MODE="skipped"
    echo "/run-plan: no test infra detected; skipping test gate — will be noted in report."
  fi
fi

Never hardcode npm run test:all, npm start, or .test-results.txt. Every subsequent reference uses $FULL_TEST_CMD, $DEV_SERVER_CMD, and $TEST_OUTPUT_FILE. Agent dispatch prompts must include the RESOLVED literal value of each var (substituted from the helper's output BEFORE emission), or the explicit "Tests: skipped — no test infra" when TEST_MODE=skipped. Markdown blockquotes (e.g., the worktree-test recipe at lines 898-930) do NOT undergo parameter expansion at emission time — YOU, the orchestrator-model, must perform the substitution before typing the blockquote into the subagent's prompt.

To resolve all three vars in one step (sibling resolution to the $FULL_TEST_CMD decision tree above), source the helper:

if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
# Informational fallbacks for the recipe (non-critical-path):
[ -z "$DEV_SERVER_CMD" ] && DEV_SERVER_CMD=npm
[ -z "$TEST_OUTPUT_FILE" ] && TEST_OUTPUT_FILE=.test-results.txt

Note: if dev_server.cmd is unset, the recipe instructs npm as a sensible default; configure dev_server.cmd for non-npm projects. The testing.output_file filename suffix is informational (not load-bearing for project semantics) — fallback to .test-results.txt is safe.

Strip pr/direct from arguments before passing to downstream processing (same pattern as stripping auto, finish, etc.).

Examples:

  • /run-plan plans/FEATURE_PLAN.md — interactive, next phase
  • /run-plan plans/FEATURE_PLAN.md 4b — interactive, specific phase
  • /run-plan plans/FEATURE_PLAN.md finish — interactive, all remaining phases (pauses between each)
  • /run-plan plans/FEATURE_PLAN.md finish auto — autonomous, all remaining phases (chunked, one phase per cron turn)
  • /run-plan plans/FEATURE_PLAN.md auto every 4h — schedule every 4h
  • /run-plan plans/FEATURE_PLAN.md auto every 4h now — schedule + run now
  • /run-plan plans/FEATURE_PLAN.md finish auto pr — autonomous, all phases, PR landing
  • /run-plan plans/FEATURE_PLAN.md direct — direct mode, work on main
  • /run-plan plans/FEATURE_PLAN.md status — show plan progress
  • /run-plan now — trigger the active cron early
  • /run-plan stop — cancel scheduled runs
  • /run-plan next — check when the next phase will run

Subcommands: status, now, next, stop

Select the subcommand based on $ARGUMENTS, then read the corresponding file in full and follow its procedure end-to-end. Do not proceed until you have read the file. Each subcommand exits before Phase 1.

Subcommand File
status subcommands/stop-next-status.md
now (standalone) subcommands/stop-next-status.md
next subcommands/stop-next-status.md
stop subcommands/stop-next-status.md

Phase 0 — Schedule (if every is present)

If $ARGUMENTS contains every <schedule>:

  1. Parse the schedule — convert to a cron expression. The LLM interprets natural scheduling expressions.

    For interval-based schedules (4h, 2h, 30m): use the CURRENT minute as the offset so the first fire is a full interval from now, not aligned to midnight. Check the current minute with date +%M:

    • 4h at minute 9 → 9 */4 * * * (fires at :09 past every 4th hour)
    • 2h at minute 15 → 15 */2 * * *
    • 30m → */30 * * * * (no offset needed for sub-hour)
    • 1h at minute 9 → 9 * * * *

    For time-of-day schedules (day at 9am, weekday at 2pm): offset round minutes by a few to avoid API busy marks:

    • day at 9am → 3 9 * * *
    • day at 14:00 → 3 14 * * *
    • weekday at 9am → 3 9 * * 1-5

  2. Deduplicate — use CronList + CronDelete to remove any whose prompt starts with Run /run-plan.

  3. Construct the cron prompt. Strip the phase number (so each invocation auto-detects the next incomplete phase). Always include now in the cron prompt so each cron fire runs immediately AND re-registers itself. Note: this now is for the CRON's invocation, not the current invocation.

    Assemble the prompt from $AUTO_FLAG state, not from literal $ARGUMENTS substrings. Cron-fired every-mode runs MUST advance between phases without human interaction, so include auto unconditionally for new every crons (auto = autonomous = skip between-phase pause + auto-merge):

    CRON_TOKENS=""
# `auto` is mandatory for `every`-mode crons (between-phase advance
# must be non-interactive). Default-on regardless of $AUTO_FLAG.
CRON_TOKENS="$CRON_TOKENS auto"
CRON_PROMPT="Run /run-plan $PLAN_FILE$CRON_TOKENS every $SCHEDULE now"

    Default new-cron shape: Run /run-plan <plan-file> auto every <schedule> now. Note: the phase number is intentionally omitted so the cron auto-advances.

  4. Create the cron — use CronCreate:

    • cron: the cron expression from step 1
    • recurring: true
    • prompt: the constructed command from step 3

  5. Confirm with wall-clock time. Always show times in the configured timezone — use TZ="${TIMEZONE:-UTC}" date for conversion, not the system timezone (which may differ):

    If now is present:

    Run-plan scheduled every 4h. Running now. Next phase run after this one: ~8:15 PM ET (cron ID XXXX).

    If now is NOT present:

    Run-plan scheduled every 4h. First run: ~4:15 PM ET (cron ID XXXX). Use /run-plan next to check, /run-plan stop to cancel.

  6. If now is present: proceed to Phase 1 (run immediately). If now is NOT present: Exit. The cron fires later.

End-of-phase scheduling note: when a phase finishes and a cron is active, always include the estimated next run time with timezone in the completion message. Example:

Phase complete. Next phase run in ~3h 45m (~11:30 PM ET, cron XXXX).

If every is NOT present, skip this phase and proceed to Phase 1 (bare invocation always runs immediately).

Phase 1 — Parse Plan & Extract Verbatim Phase Text

The key differentiator. Plans have varied formats, so the agent uses LLM comprehension rather than rigid parsing.

Read authority (PLAN_FILE_FOR_READ) — compute before ANY plan read

Before any read of the plan file (frontmatter, tracker, phase text), compute the authoritative source for this invocation.

Why this matters. In PR mode, per-phase tracker updates (🟡 In Progress → ✅ Done, status: complete) commit on the feature branch, per the PR-mode bookkeeping rule. Main's copy of the plan file is stale across cron-fired finish auto pr re-entries until the squash merge lands at plan completion. A naive cat plans/<plan>.md from the orchestrator's CWD (main) would silently show ⬚/⬚ on turn 2 even when Phase 1 is already done on the feature branch — causing the re-entry check to re-execute already-done phases. Cherry-pick and direct modes commit bookkeeping on main directly, so main is authoritative there.

# Compute BEFORE Step 0. LANDING_MODE is already resolved from args/config
# in the argument-detection section at the top of this skill.
PLAN_SLUG=$(basename "$PLAN_FILE" .md | tr '[:upper:]' '[:lower:]' | tr '_' '-')
# Pre-worktree bootstrap: anchor on $CLAUDE_PROJECT_DIR (orchestrator session
# root) — WORKTREE_PATH is not yet in scope at the read-authority block.
MAIN_ROOT="$CLAUDE_PROJECT_DIR"
PROJECT_NAME=$(basename "$MAIN_ROOT")
PR_WORKTREE_PATH="/tmp/${PROJECT_NAME}-pr-${PLAN_SLUG}"

if [ "$LANDING_MODE" = "pr" ] && [ -d "$PR_WORKTREE_PATH" ]; then
  PLAN_FILE_FOR_READ="$PR_WORKTREE_PATH/$PLAN_FILE"
  echo "PR-mode re-entry: reading plan from feature-branch worktree at $PR_WORKTREE_PATH"
else
  PLAN_FILE_FOR_READ="$MAIN_ROOT/$PLAN_FILE"
fi

Every subsequent plan read MUST use $PLAN_FILE_FOR_READ, including Step 0's re-entry check, all of Parse Plan's steps, and the Status command (which duplicates this computation for its own read-only early-exit path). The plain $PLAN_FILE (relative to CWD) would silently point at main's stale copy in PR-mode chunked re-entries.

Writes are unaffected. Phase 4 tracker updates and Phase 5b frontmatter updates continue to follow the PR-mode bookkeeping rule (commit on feature branch in PR mode; commit on main in cherry-pick/direct mode). Only the read path needed the explicit branch.

Preflight checks

Before parsing, check for stale state from a previous failed run:

  1. Idempotent re-entry check (chunked finish auto only). If running with finish auto, this turn may have been triggered by a cron from a previous turn. Re-emit the pipeline ID first (cron-fired turns are fresh sessions):

    TRACKING_ID=$(basename "$PLAN_FILE" .md | tr '[:upper:]_' '[:lower:]-')
echo "ZSKILLS_PIPELINE_ID=run-plan.$TRACKING_ID"

    Sentinel-recovery prelude (#110). Before evaluating the four cases below, check for a cron-recovery-needed.<phase> marker left by a prior turn whose CronCreate failed after a successful CronDelete (high-severity race documented in WI 1.3 step 4d). The marker means the recurring */1 cron may not exist; this turn must try to re-establish it before doing anything else. The counter is held — this is recovery, not normal flow.

    if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
# MAIN_ROOT is already in scope from the "Read authority" block earlier
# in this section (line ~393); reuse it here.
PIPELINE_ID="${ZSKILLS_PIPELINE_ID:-run-plan.$TRACKING_ID}"
PIPELINE_ID=$(bash "$ZSKILLS_SKILLS_ROOT/create-worktree/scripts/sanitize-pipeline-id.sh" "$PIPELINE_ID")
if compgen -G "$MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/cron-recovery-needed.*" >/dev/null 2>&1; then
  # CronList → check if a "Run /run-plan <plan-file> finish auto" cron
  # already exists (a stale fire from before the failed Delete may have
  # raced ahead of us). The literal `finish auto` composite alias is
  # preserved indefinitely (D2-RP load-bearing user workflow): on
  # /run-plan re-entry, the parser sets FINISH_MODE=finish-auto and
  # hoists AUTO_FLAG=1, so the cron-fired turn runs autonomously and
  # lands with --auto.
  # If exists AND cadence ∈ {*/1, */10, */30, */60} (sane backoff cadence
  #   set, A1 fix): rm cron-recovery-needed.* (already recovered at a
  #   sane cadence; trust it).
  # If exists BUT cadence ∉ {*/1, */10, */30, */60} (A1 fix: third-party
  #   cron at e.g. */15, or scheduler corruption returning bad cadence):
  #   emit WARN cron-recovery-bad-cadence with the observed cadence
  #   string, force CronDelete on ALL matching crons, then fall through
  #   to the "missing" branch below to CronCreate at */1.
  # If missing: CronCreate cron="*/1 * * * *" recurring=true
  #             prompt="Run /run-plan <plan-file> finish auto"
  #             then verify via CronList again AND verify the new cron's
  #             cadence is exactly "*/1 * * * *" (not just "exists").
  #             On success: rm cron-recovery-needed.*. On failure: leave
  #             marker, emit WARN cron-recovery-failed and continue to
  #             case dispatch (Case 3's own inline retry may succeed, or
  #             Case 4 will happy-path past the missing cron).
fi

    The cadence-sanity check (A1 fix) protects against three failure modes: (i) a third-party tool created a recurring cron with the same prompt at a different cadence (e.g., */15); (ii) Case 3's 3-retry exhaustion left a partial-success cron at the wrong target cadence; (iii) the previous turn's CronCreate raced with another top-level invocation. Without this check, the "exists, rm marker" branch would silently accept a wrong cadence and the pipeline would run at the wrong fire rate indefinitely.

    Then read the plan frontmatter (status field) and the plan tracker (phase statuses) from $PLAN_FILE_FOR_READ (computed in the "Read authority" section above — NOT from main's copy of the plan). Four cases:

    1. Frontmatter status: complete: plan truly done. Terminal cron cleanup (Design 2a): call CronList and CronDelete on any job whose prompt matches Run /run-plan <plan-file> finish auto for THIS plan file. In Design 2a chunking, the recurring */1 cron will otherwise keep firing forever — Case 1 is the only routine termination path. Also rm any leftover recovery sentinel and per-phase defer counters so the next pipeline starts clean (R6 fix, #110):

      if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
PIPELINE_ID="${ZSKILLS_PIPELINE_ID:-run-plan.$TRACKING_ID}"
PIPELINE_ID=$(bash "$ZSKILLS_SKILLS_ROOT/create-worktree/scripts/sanitize-pipeline-id.sh" "$PIPELINE_ID")
rm -f "$MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/cron-recovery-needed."*
rm -f "$MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/in-progress-defers."*

      Then exit with "Plan complete (already). Cron deleted." No more work, no more fires.

    2. All phases Done + frontmatter NOT complete: Phase 5b needs to run (it owns the final-verify gate logic via its new first sub-step). Skip Phase 1 sub-steps 1–9 and Phases 2–5; route directly to Phase 5b. Phase 5b's gate handles the verify-pending vs verify-fulfilled vs no-marker cases — single source of truth, no duplicated logic in Step 0.

    3. Next-target phase already In Progress (per tracker): apply the adaptive backoff decision rule (#110). The pipeline cron stays at its current cadence on most fires and steps down to a slower cadence only at boundary fires C+1 ∈ {1, 10, 16, 26}. The counter C is per-phase scoped.

      The DECISION is factored into a pure script — defer-backoff-decide.sh — so the (bug-prone) arithmetic/branching is unit-tested in isolation (tests/test-runplan-defer-backoff.sh) and can never drift silently from the prose. The Cron* tool calls stay HERE in prose; the script only decides WHICH of them to make.

      1. Read C from $MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/in-progress-defers.<phase> (default 0 if missing). Read current cadence R via CronList substring match on Run /run-plan <plan-file> finish auto (if multi-match, pick the first for cadence read — the delete-all directive collapses all). Note the CronList match count N (0 when no cron matches). Then ask the decision script which directives to apply:

        DIRECTIVES=$(bash "$ZSKILLS_SKILLS_ROOT/run-plan/scripts/defer-backoff-decide.sh" \
  --counter "$C" \
  --cadence "$R" \
  --cronlist-match "$N" \
  --create-result ok \
  --case 3 \
  --recovery-marker no \
  --phase "$PHASE")

        (--create-result is ok on entry; flip to missing / missing-after-3-retries and re-ask only if the verify in directive REPLACE_CRON below comes back short — see step 3d.)

      2. The script computes target cadence T from C+1 (<10 → */1, 10..15 → */10, 16..25 → */30, ≥26 → */60) and emits one directive per line. Interpret them top-to-bottom:

        • WARN no-cron-match — no cron matched (N == 0); do NOT increment counter, output the defer message, exit.

        • DELETE_ALL_MATCHING_CRONS — CronList → enumerate ALL prompts containing Run /run-plan <plan-file> finish auto, then CronDelete each ID (T != R, so the cadence is changing).

        • SLEEP_BETWEEN_RETRIES — sleep 2 before the CronCreate retry (N1 fix: inter-attempt spacing protects against rate-limit-class CronCreate failures, which would otherwise burn all 3 retries inside the same rate-limit window).

        • REPLACE_CRON T — CronCreate ONE cron with cron: T, recurring: true, prompt: "Run /run-plan <plan-file> finish auto".

        • WRITE_COUNTER N — write N (= C+1) to the counter file $MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/in-progress-defers.<phase>.

        • PROCEED defer-message-printed — output the defer message (boundary fire C+1 ∈ {1, 10, 16, 26}):

          Phase X already in progress, deferring. Backoff cadence now T.

        • PROCEED defer-message-silent — advance silently (intermediate fire, so users see meaningful step-down events but not minute-by-minute noise).

      3. Verify + retry on REPLACE_CRON. After a CronCreate, verify via CronList again; if no match found OR cadence != T, re-ask the script with --create-result missing (which emits SLEEP_BETWEEN_RETRIES then REPLACE_CRON T) and retry steps c–d up to 2 more times (3 total CronCreate attempts; worst-case wall-time on the failing path ≈ 4-6s of sleep + 6 LLM tool calls). On the 3rd exhausted attempt, re-ask with --create-result missing-after-3-retries; the script then emits the high-severity-race directives (no WRITE_COUNTER):

        • WARN cron-replace-failed (3 retries exhausted) — emit to stdout.

        • WRITE_RECOVERY_MARKER <phase> — write the cron-recovery-needed.<phase> sentinel.

        • EMIT_USER_WARN cron-stalled — output a prominent user-visible WARN to the turn's final message:

          ⚠ /run-plan finish auto: failed to update cron after 3 attempts. Pipeline is stalled until you re-invoke /run-plan finish auto.

          If the next invocation also fails: run /run-plan stop to clear all crons, then file an issue at github.com/zeveck/zskills/issues/new with the contents of .zskills/tracking//cron-recovery-needed. and your CronList output.

          (N2 fix: explicit escalation path — /run-plan stop + manual gh issue filing — so users have a complete action ladder rather than a re-invoke-or-give-up choice.)

          Do NOT increment counter. Exit.

      When T == R the script emits no DELETE_ALL_MATCHING_CRONS / REPLACE_CRON (no cron action) — only WRITE_COUNTER + PROCEED.

    4. Otherwise: proceed with normal preflight (steps 1–9) then Phase 2. Before proceeding, clear all per-phase defer counters and any stale recovery sentinel from a prior phase (#110):

rm -f "$MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/in-progress-defers."*
rm -f "$MAIN_ROOT/.zskills/tracking/$PIPELINE_ID/cron-recovery-needed."*

      (Harmless on first phase — rm of missing files is a no-op.)

    Stale crons are harmless — duplicate fires exit cleanly via this check. Re-entry routes to Phase 5b which owns verify-pending state and self-rescheduling.

Plan-claim acquire (W2a.1, A11 / AC2a.7). Acquire a single-host atomic claim on this plan BEFORE any mode-detection branch (so the claim is reachable from worktree / PR / cherry-pick / direct / delegate paths). On race-lost (exit 10) this fence terminates cleanly; the orchestrator reports "declined" and exits the turn — a second pipeline already owns the plan and our session must not double-fire /run-plan for it.

claim-plan.sh is ownership-aware (self-re-entry returns 0), so a chunked finish auto re-fire re-acquiring its OWN plan claim with the stable run-plan.$TRACKING_ID pipeline_id succeeds — exit 10 here therefore means ONLY a truly-foreign pipeline holds the plan, which is exactly when "declined" is the correct verdict (D8 / #803).

Self-re-entry contract (twins: claim-plan.sh / claim-issue.sh)

Both twin primitives share one ownership-aware self-re-entry decision, implemented by the helper skills/create-worktree/scripts/claim-self-reentry.sh (invoked as a bash subprocess on each twin's already-exists branch — NEVER sourced, since its exit codes would terminate a sourcing caller). The exit-code contract is: acquire — 0 = fresh-OR-self (the existing claim is the caller's own pipeline_id, or there was no claim and we just took it → proceed), 10 = foreign-OR-absent/malformed (another pipeline holds it, or claim.json is missing/truncated → never steal), 11 = filesystem infrastructure failure, 2 = usage error; release — 12 = ownership mismatch (the claim is held by a different pipeline_id; release refuses). There is NO TTL — a claim is released ONLY by an explicit release call, so a re-entering self always sees its own claim and proceeds (0), and a foreign holder is honored until that holder explicitly releases.

Same-plan in-flight guard (issue #883)

Cron re-fires can land while the previous turn of THIS SAME plan is still mid-flight (chunked finish auto re-fires /run-plan $PLAN_FILE every interval, and CronCreate's "fires only while idle" is turn-level idle, not task-level). claim-plan.sh does NOT close this: its self- re-entry returns rc=0 (proceed) for any same-pipeline re-acquire (#825), so two same-session same-plan turns both pass the claim gate. The shared check-inflight-batch.sh helper, called with the per-work- identity --pipeline-id filter, distinguishes "same plan re-fire mid- flight" (skip) from "different plan in-flight" (proceed):

  • Two /run-plan invocations for DIFFERENT plans → each writes its own inflight/run-plan/run-plan.<plan-a>.json / <plan-b>.json sentinel; the --pipeline-id filter ensures cross-plan fires don't collide.
  • Two cron fires of /run-plan $PLAN_A while phase-N is still running → the second fire sees the same-pipeline sentinel and exits clean, leaving the in-flight turn to finish on its own.

The sentinel is cleared at all /run-plan terminal exit points (Phase 5b's already-complete no-op release + Phase 6's terminal-merge release; both in modes/execute-phase.md). Stale escape lives in the helper (2h max-age) — a crashed turn's sentinel is reclaimed automatically.

Issue-claim acquire (W3.1/W3.2/W3.5, #803 execution-window protection). If the plan's frontmatter carries one or more issue: N fields, claim each linked issue-<N> for the plan's FULL lifetime — held across idle gaps between chunked fires (filesystem + no-TTL + self-re-entry make this automatic) and released ONLY at the plan's terminal release points (execute-phase.md terminal merge, the already-complete no-op, and the operator-stop sweep — NEVER per-phase). The issue claim uses run-plan's OWN $PIPELINE_ID (same as the plan claim) and --sprint-id "$PIPELINE_ID".

This arm is DELIBERATELY different from the plan-claim decline arm above: issue-foreign-at-start is WARN-and-PROCEED, never abort. #739 removed auto-expiry, so a possibly-stale issue claim must not block a deliberately-run plan — the plan owns the plan; the issue contention is a softer operator signal. On rc=10 we log loudly and CONTINUE, and we NEVER release the legitimately-won plan claim (no plan-claim leak).

Parse the bare-integer issue number(s) from $PLAN_FILE_FOR_READ's frontmatter (the PR-mode-worktree-aware read authority — NOT bare $PLAN_FILE). Strip # and surrounding quotes to a bare positive integer (claim-issue.sh validate_issue_number rejects non-numeric input with exit 2), aligning with the Close-linked-issue parser's tolerance for issue: 42 and issue: "#42".

  1. In-progress git operation?

    ls .git/CHERRY_PICK_HEAD .git/MERGE_HEAD .git/REBASE_HEAD 2>/dev/null
git status --porcelain | grep '^UU\|^AA\|^DD'

    If either command produces output, STOP. Invoke the Failure Protocol.

  2. Stash stack?

    git stash list

    If there is a stash with message containing "pre-cherry-pick", a previous run's stash was never restored. STOP. Invoke the Failure Protocol — the user needs to git stash pop or git stash drop before a new phase can start safely.

  3. Leftover plan worktrees?

    git worktree list

    If worktrees from a previous run exist (paths containing plan-), warn the user. Do not remove them — note their presence and continue.

  4. Unconfigured test-command config?

    if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
# Lane-agnostic: $FULL_TEST_CMD is read from .claude/zskills-config.json
# at the project root, the SAME source the hook itself reads at runtime.

    This gate is an early-exit mirror of the hook's own commit-block: when testing.full_cmd is unset/empty in .claude/zskills-config.json AND test infrastructure exists, the hook will block the eventual git commit with "BLOCKED: project has test infrastructure ... but testing.full_cmd is empty" (Case C at hooks/block-unsafe-project.sh.template:714-729) — so catching it at preflight just prevents wasted work. Its job is to notice when a project has test infrastructure but the config doesn't yet name a test command.

    Why the config read, not a hook grep. The hook resolves UNIT_TEST_CMD / FULL_TEST_CMD at runtime from .claude/zskills-config.json (hooks/block-unsafe-project.sh.template:579-606) — there are no {{...}} placeholders left in the hook body to scan for. Both install lanes share that one config file, so the resolver is lane-agnostic by construction: the legacy lane reads .claude/zskills-config.json directly; the plugin lane's hook lives under ${CLAUDE_PLUGIN_ROOT} but still reads the SAME .claude/zskills-config.json in the checked-out tree (the resolver above mirrors that contract).

    Three cases, report each explicitly so the reasoning is legible:

    • FULL_TEST_CMD empty AND test infra exists — where test infra means any of: package.json with a "test" script, vitest.config.*, jest.config.*, pytest.ini, .mocharc.*, Makefile, or tests/*.sh|*.py|*.js (this list must match hooks/block-unsafe-project.sh.template:611-630 exactly, otherwise preflight under-reports and the hook still blocks at commit time): STOP. Test-command config has not been set — run /update-zskills first, or (if this plan's purpose is to configure it) have the plan land those changes in an early phase before real enforcement matters. Report: "hook-config gate tripped: testing.full_cmd unset AND test infra detected — stopping."
    • FULL_TEST_CMD empty, no test infra: gate silent, proceed. This is either a fresh/bootstrap project or one with no tests by design. If the plan establishes tests, it should also fill the testing config (testing.unit_cmd, testing.full_cmd, and optionally ui.file_patterns in .claude/zskills-config.json) in the same phase, so subsequent runs have real enforcement. Report: "gate silent: testing.full_cmd unset but no test infra yet — bootstrap or tests-by-design; if this plan adds tests, also fill testing.full_cmd."
    • FULL_TEST_CMD non-empty: config is set, nothing to do. Report: "testing.full_cmd configured; gate n/a."

    If the resolver itself fails to read .claude/zskills-config.json (missing or malformed), FULL_TEST_CMD ends up empty and the gate falls through the same three cases above, which is the correct behavior — a missing config in a project with test infra is exactly the misconfiguration the hook's Case-C block exists to catch.

  5. Clean up landed worktrees from previous phases

    if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
for wt_line in $(git worktree list --porcelain | grep '^worktree ' | sed 's/^worktree //'); do
  if [ -f "$wt_line/.landed" ] && grep -q 'status: landed' "$wt_line/.landed"; then
    echo "Cleaning up landed worktree: $wt_line"
    bash "$ZSKILLS_SKILLS_ROOT/commit/scripts/land-phase.sh" "$wt_line"
  fi
done

    This catches stragglers from crashed agents, container restarts, or any remaining edge cases. Defense in depth — .claude/skills/commit/scripts/land-phase.sh is the primary fix (called after each phase landing), the preflight is the safety net.

Plan-cited preflights — open-PR file-path conflict gate

When a plan touches a path prefix (e.g. skills/update-zskills/) across multiple phases AND runs in PR mode, every phase's preflight needs to self-filter the pipeline's OWN PR. Inlining gh pr list --state open --limit 100 --json number,title,files | grep -F '<prefix>' in each phase trips the gate from Phase 2 onward, because the pipeline's own feature branch becomes the only matching PR (issue #177).

Plans MUST cite the helper instead of inlining the gh+grep pattern:

if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
# In a plan phase that needs an open-PR conflict gate. The orchestrator
# already tracks $RUN_PLAN_PR_NUMBER (the pipeline's own PR) — pass it via
# --exclude-pr so the gate self-filters.
if ! bash "$ZSKILLS_SKILLS_ROOT/run-plan/scripts/pr-preflight.sh" \
     --path-prefix "skills/update-zskills/" \
     --exclude-pr "${RUN_PLAN_PR_NUMBER:-}"; then
  echo "FAIL: open PR(s) touch the path; coordinate before continuing." >&2
  exit 1
fi

The helper:

  • Takes --path-prefix <prefix> (required) and --exclude-pr <num> (optional).
  • Emits matching PR numbers on stdout, one per line; empty when clean.
  • Exit 0 when clean, 1 when at least one matching PR remains, 2 on arg or gh error.
  • --exclude-pr may be empty — the script then performs no exclusion, so it is safe to call BEFORE the orchestrator knows the pipeline's PR number (e.g. Phase 1 of a plan that has not yet been pushed).

Source: skills/run-plan/scripts/pr-preflight.sh. Pure bash; no jq.

Parse plan

  1. Read the plan file in full from $PLAN_FILE_FOR_READ (see "Read authority" section above — in PR mode with an existing feature-branch worktree, this resolves to the worktree's copy; otherwise main's copy). Also read any companion progress document if referenced (e.g., FEATURE_PROGRESS_AND_NEXT_STEPS.md) — same path rule applies.

  2. Extract phases and status — handle four formats:

    • Progress tracker table (FEATURE_PLAN style): rows with ✅ Done, ⬚ (not started), 🟡 (in progress), etc.
    • Numbered phase sections (## Phase 4a — Title): look for completion markers in the section body or companion doc
    • Checklist (- [x] / - [ ]): checked = done, unchecked = not done
    • Narrative: infer status from codebase evidence (files exist, tests pass, etc.)

  3. Determine target phase:

    • If phase arg given: use it. If already complete, warn (or skip in auto)
    • If no phase arg: first incomplete phase
    • If ALL phases complete:
      • If frontmatter status: complete: report "Plan complete" → stop. If every, delete the cron via CronList + CronDelete.
      • If frontmatter NOT complete: route to Phase 5b directly (Phase 5b's gate handles final-verify deferral; if final-verify is satisfied or not required, Phase 5b completes the plan).
    • If multiple phases share the same number (e.g., 4a, 4b, 4c), treat each sub-phase as a separate phase

Recoverable-STOP sentinel hygiene (Issue #923). Steps 4–6 below each have a recoverable STOP that deliberately leaves the every/finish auto cron alive to retry on a later fire (dependency-not-met, phase-in-progress conflict, staleness). Before taking any of those STOP-and-exit branches, clear the #883 in-flight sentinel — otherwise the retry fire (same (session_id, pipeline_id)) is treated as a redundant re-fire and SKIPPED until the 2h staleness reclaims it, defeating the intended retry. Re-derive $PIPELINE_ID / $INFLIGHT_HELPER at fence-top exactly as the terminal-clear sites in modes/execute-phase.md do (config-source first):

if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then
  export CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}"
  . "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh"
else
  . "$CLAUDE_PROJECT_DIR/.claude/skills/update-zskills/scripts/zskills-resolve-config.sh"
fi
PIPELINE_ID="${ZSKILLS_PIPELINE_ID:-run-plan.$TRACKING_ID}"
PIPELINE_ID=$(bash "$ZSKILLS_SKILLS_ROOT/create-worktree/scripts/sanitize-pipeline-id.sh" "$PIPELINE_ID")
INFLIGHT_HELPER="$ZSKILLS_SKILLS_ROOT/create-worktree/scripts/check-inflight-batch.sh"
if [ -x "$INFLIGHT_HELPER" ]; then
  bash "$INFLIGHT_HELPER" clear run-plan --pipeline-id "$PIPELINE_ID" || true
fi

This is distinct from Step 0 Case 3's adaptive-backoff defer — that path is a genuine "phase actively in progress, keep deferring" yield and MUST keep the sentinel set; do NOT add the clear there.

  1. Check dependencies — if a prerequisite phase isn't Done, STOP (clear the sentinel via the fence above first). Report which dependency is missing. If every, the cron retries later.

  2. Check for conflicts — if the target phase is "In Progress" (🟡 or equivalent), another agent may be working on it. STOP (clear the sentinel via the fence above first). Do not compete.

  3. Check for staleness. Two independent checks. If a check forces a STOP-and-exit that leaves the cron alive to retry, clear the sentinel via the fence above first.

    a. Textual staleness. if the plan's Dependencies section contains language like "drafted before," "may need refresh," or "APIs and data structures referenced here are based on [another plan's] design, not actual code," the plan may be stale:

    • Without auto: tell the user "this plan was drafted before its dependency was implemented. Want me to refresh it with /refine-plan?"
    • With auto: dispatch /refine-plan <plan-file>$AUTO_ARG on the plan file to update it (the trailing $AUTO_ARG propagates auto so /refine-plan's own AUTO_FLAG fires and it dispatches /land-pr per #648). After the refresh, re-read the plan and continue.
    • Skip this check if the plan file was modified more recently than the dependency's completion (it may already be up to date).

    b. Arithmetic staleness (pre-dispatch). For the target phase's ### Acceptance Criteria section, extract numeric targets and verify against current source.

    Procedure:

    1. Read the target phase's ### Acceptance Criteria bullets.
    2. For each bullet, attempt to match a numeric claim via the token-compatible grammar (Phase 1 <stated> forms: N-M, ≤N, ≥N, ~N, exactly N). Unmatched bullets skip.
    3. For each matched claim, locate the corresponding extraction rule (if any) in the target phase's ### Design & Constraints section. Supported rules:
      • Literal arithmetic expression: "N - M + K" → evaluate via .claude/skills/run-plan/scripts/plan-drift-correct.sh --eval "N - M + K" (the script implements parse-only integer arithmetic; no shell eval, no injection surface).
      • "extract lines N..M" or "lines N-M" → value is M - N + 1.
      • "SKILL.md X lines down from Y" → value is Y - X or X (case- by-case; script uses a small fixed set of patterns).
      • No derivable rule → skip bullet, emit info line: "pre-dispatch arithmetic check: skipped (no derivable rule)".
    4. Compute drift between stated target and derived value. Use the same --drift command as Phase 3.5.
    5. Collect findings per bullet.

    Decision:

    • Without auto: present findings: 
      Pre-dispatch arithmetic drift:
Phase <N>: <bullet-text>
  plan says: <stated>
  arithmetic says: <derived>
  drift: <pct>%
      Ask user: "(1) proceed (Phase 3.5 will post-correct small drift), (2) pause for /refine-plan, (3) override (suppress this check for this phase)?"
    • With auto: if any bullet has drift >20%, dispatch /refine-plan <plan-file>$AUTO_ARG (plan-level issue, not per-band; the trailing $AUTO_ARG propagates auto so /refine-plan dispatches /land-pr per #648); after refresh, re-read and continue. If all drifts are ≤20%, log findings to the phase report and proceed — Phase 3.5 will auto-correct post-hoc within the ≤20% band.

  4. Save the VERBATIM phase text — copy the entire section from the plan file exactly as written. Every sentence, every bullet, every formula, every constraint. This text will be passed to agents in Phase 2 and Phase 3.

    Do NOT summarize, paraphrase, or reinterpret. The plan is the spec.

    Lesson from /fix-issues #387: summarized descriptions caused agents to implement the wrong thing. "Reset button" was interpreted as "clear canvas" instead of "reset mappings to defaults" because only the title was read. The same will happen with plan phases if the orchestrator summarizes "implement translational mechanical domain" without the formulas, state equations, and design constraints.

  5. Create tracking fulfillment marker. Determine the tracking ID: use the ID passed by the parent skill if this is a delegated invocation, or derive from the plan file slug if standalone (e.g., FEATURE_PLAN.md → feature-plan). Then create the fulfillment file in the MAIN repo:

    if [ -f "${CLAUDE_PLUGIN_ROOT}/skills/update-zskills/scripts/zskills-resolve-config.sh" ]; then

  6. Classify UI impact from the plan text. Scan the phase description for UI indicators: mentions of editor, toolbar, canvas, panel, dialog, CSS, button, menu, viewport, renderer, dark mode, layout, or any reference to UI/editor/styles directories in the project. Flag the phase as UI-touching if any are found.

    In finish mode, classify ALL phases upfront and report:

    Running 5 phases. Phases 3 and 5 touch UI
