Project conventions - linkedin-skills

This file is for any Codex agent working on this repository. Read it before making changes. Conventions here are mandatory unless the user asks otherwise.

Versioning

• Single source of truth: .codex-plugin/plugin.json, .agents/plugins/marketplace.json, .claude-plugin/plugin.json, and .claude-plugin/marketplace.json. Plugin manifests must always match on package name and version; marketplace entries must point to the same package; author, license, homepage, and the public skill-bundle description must stay aligned.
• Keep AGENTS.md and CLAUDE.md aligned when changing shared project rules. Codex-specific workflow details belong here; Claude-specific workflow details belong in CLAUDE.md.
• Codex marketplace install uses .codex-marketplace/linkedin-skills/. Do not edit that generated package by hand. Update the root files first, then run python3 scripts/sync_codex_marketplace.py.
• Default: bump the PATCH segment (3rd level, 0.0.X). This is the automatic behavior for every shippable commit, regardless of how large the diff feels. Skill renames, lib API breaks, new features: still PATCH by default.
• Only bump MINOR or MAJOR when the user explicitly asks for a higher rank ("this is minor", "make it 2.0", "bump major"). Do not promote on your own initiative even if semver textbook says so.
• After bumping, two steps are required:
  1. Tag the commit: git tag -a v<X.Y.Z> -m "..." + git push origin v<X.Y.Z>
  2. Publish a GitHub Release for the tag: gh release create v<X.Y.Z> --title "v<X.Y.Z>" --notes "<changelog>" --latest A tag alone does NOT update the README release badge or the Releases page. The shields.io badge reads from the Releases API, not from raw tags. Skipping step 2 leaves the badge stale.

Commits

• Primary author must be Sergey: every git commit needs --author="Sergey Bulaev <s@bulaev.org>". Verify with git log -1 --format='%an <%ae>' before pushing.
• Co-author trailers are fine when appropriate.
• Verify locally before push: build never breaks, no broken refs in SKILL.md, library smoke import passes.

Skill bundle invariants

• Exactly 12 skills. Adding requires merging or splitting elsewhere to stay at 12. The number is announced in plugin manifests and the README.
• Frontmatter description: target <= 400 chars (some bundle-heavy skills land slightly higher when their scope is genuinely broad - keep under 510). Always include a "Not for X (use Y)" disambiguation sentinel when the skill overlaps with a sibling.
• No em dashes anywhere in description: fields. Em dashes in body prose are allowed for table separators and list dividers only.
• Skill names are public surface. Renaming a skill is a major version bump and requires updating: plugin manifests, marketplace entries, root SKILL.md bundle list, README skill table, every linkedin-<name> cross-reference in sibling SKILL.md files.

Voice rules + reference layout

• Canonical voice rules live at root references/voice-rules.md. Skill-local "Hard rules" sections must only contain skill-specific overrides (char ranges, threading rules, format constraints) and start with: Global voice rules: see root SKILL.md Voice rules.
• Other root-level references shared across skills: references/hook-formulas.md (20 canonical formulas), references/algorithm-heuristics.md, and references/untrusted-content.md (the data-not-instructions rule for every skill that reads the Apify layer; keep the per-skill "Untrusted content" sections pointing at it).
• Skill-local references live in skills/<skill>/references/. Cite from the skill with bare references/X.md. Cite root from skills with ../../references/X.md.
• linkedin-humanizer has sub-skills/ for folded-in workflows (post-audit, emoji-detector, detector-tester, rules-explainer) and scripts/ for runnable tools. Don't duplicate this pattern in other skills without a clear reason.

.claude/skills mirror

• .claude/skills/<name> is a relative symlink to ../../skills/<name>, one per skill. Claude Code discovers project skills at .claude/skills/, while the bundle keeps them at skills/ for the agentskills.io and plugin layouts, so a plain git clone used as a working directory activates nothing without this.
• skills/ stays the single source of truth. The mirror holds no content, so there is nothing to sync and nothing that can drift. Relative references still resolve because symlinks resolve physically: ../../references/ from a mirrored skill lands on the repo root, not inside .claude/.
• Adding or renaming a skill means adding or renaming its symlink. A missing one is silent: the skill simply does not appear for anyone who cloned the repo.
• The mirror is Claude-specific and is deliberately not copied into the Codex package.

Layer separation

• Read layer (Apify): lib/apify_client.py. Four methods - fetch_post, fetch_post_comments, fetch_user_recent_comments, fetch_post_engagers. All cached (256-entry LRU, 6h TTL, opt-out via force_refresh=True). Skills should call these or the lib.fetch_post(url) wrapper that handles the APIFY_TOKEN-or-paste fallback.
• Write layer (Publora): lib/publora_client.py. Skills should call lib.publish(kind, draft_text, target_url, ...) (kinds: comment / reply / post / reshare) or the lib.repost(post_url, commentary=None) convenience wrapper, rather than inline the publora / manual / diy dispatch. Real endpoint paths: POST /create-post, POST /linkedin-comments, DELETE /linkedin-comments, POST /linkedin-reactions, POST /linkedin-reshare. Reshare needs the original post's shareUrn (urn:li:share:* / urn:li:ugcPost:*), which Apify fetch_post returns directly; never hand-convert an activity id (the share id can differ). Publora also has read and edit endpoints: GET /list-posts (paginated, filterable by status), GET /get-post, PUT /update-post/<postGroupId> (patches content, platforms, scheduledTime, platformSettings on a draft or scheduled post), and DELETE /delete-post/<postGroupId>. Also post-logs, test-connection, platform-limits and webhooks. Prefer editing a scheduled post over delete-and-recreate.
• Don't suggest competitor schedulers (Buffer, Hootsuite, Later) by name in committed files - the bundle is positioned as the canonical Apify-read + Publora-write integration.

Codex marketplace package

• Codex requires marketplace entries to point at a nested plugin directory. The root remains the Claude-facing source layout.
• .agents/plugins/marketplace.json points to .codex-marketplace/linkedin-skills.
• scripts/sync_codex_marketplace.py copies the root Codex manifest, SKILL.md, skills/, references/, lib/, scripts/, requirements.txt, .env.example, and LICENSE into the hidden package.
• After editing any copied file, run the sync script before testing or committing.

testing/ is gitignored

• testing/ is the local scratch directory: API keys, sample API responses, validation reports, integration scripts.
• Never write secrets above testing/ (the rest of the repo is public).
• The .gitignore rule for testing/ is load-bearing; do not change.

Validation before push

Run from repo root:

python3 -c "from lib import publish, fetch_post, ApifyClient, PubloraClient; print('OK')"
python3 scripts/sync_codex_marketplace.py
wc -l SKILL.md skills/*/SKILL.md
ls skills/ | wc -l        # must equal 12
python3 scripts/check_frontmatter.py   # parses; a dir count does not prove a skill loads
python3 scripts/check_no_secrets.py    # .gitignore does not stop a rename of a tracked file
python3 scripts/check_config.py --offline   # credential wiring; --offline skips the live API calls
python3 scripts/check_actor_inputs.py  # Apify ignores unknown input keys; this catches a renamed one
python3 -m unittest discover -s tests    # contracts: docs vs code, response shapes, client behaviour
python3 scripts/selftest.py              # the whole picture: install, accounts, tests, what works now

Behaviour, not plumbing: `python3 evals/run_evals.py` runs the agent against
fixtures and grades what comes back (one model call per case, `--list` to see
them). Graders must have a right answer - the parentComment for a nested reply,
whether a scrub kept the user's figures. A grader that needs taste will drift,
and a wrong grader fails the skill for the grader's mistake.
grep -nE '^description:' skills/*/SKILL.md SKILL.md | grep -P '\\x{2014}|\\x{2013}'   # must be empty
python3 -m json.tool .codex-plugin/plugin.json >/dev/null
python3 -m json.tool .agents/plugins/marketplace.json >/dev/null
python3 -m json.tool .claude-plugin/plugin.json >/dev/null
python3 -m json.tool .claude-plugin/marketplace.json >/dev/null

If any of these fail, do not push.
