## What agentic-stack does

`agentic-stack` gives any AI coding agent a **portable brain**: a `.agent/` folder containing four memory layers, a progressive-disclosure skill system, enforced permissions, and adapters for eight harnesses. When you switch from Claude Code to Cursor (or any other supported harness), the agent's accumulated knowledge travels with the project — no re-learning, no lost lessons.

### Core concepts

| Concept | Description |
|---|---|
| **Memory layers** | `working/` (session), `episodic/` (action log), `semantic/` (graduated lessons), `personal/` (preferences) |
| **Skills** | Markdown files with trigger matching; manifest always loads, full `SKILL.md` only when relevant |
| **Protocols** | Typed tool schemas, `permissions.md`, delegation contracts |
| **Review protocol** | `auto_dream.py` stages candidates mechanically; host agent reviews with CLI tools |
| **Harness adapters** | Thin shims per tool (CLAUDE.md, .windsurfrules, AGENTS.md, etc.) |

Upgrade

brew update && brew upgrade agentic-stack

Onboarding wizard

The wizard runs automatically after adapter installation and writes:

• .agent/memory/personal/PREFERENCES.md — first file the AI reads each session
• .agent/memory/.features.json — feature toggles

# accept all defaults silently (CI / scripted environments)
agentic-stack claude-code --yes

# re-run wizard on an existing project
agentic-stack claude-code --reconfigure

Wizard questions

Manual preference editing

# Edit preferences any time
$EDITOR .agent/memory/personal/PREFERENCES.md

# Toggle features
$EDITOR .agent/memory/.features.json

.features.json example:

{
  "fts_memory_search": false
}

Key CLI commands

Review protocol (host-agent tools)

# List pending candidate lessons, sorted by priority
python3 .agent/tools/list_candidates.py

# Accept a candidate (--rationale required — rubber-stamping is structurally impossible)
python3 .agent/tools/graduate.py <id> --rationale "evidence holds, matches PREFERENCES"

# Reject a candidate (--reason required; decision history preserved)
python3 .agent/tools/reject.py <id> --reason "too specific to this repo to generalize"

# Requeue a previously-rejected candidate
python3 .agent/tools/reopen.py <id>

Memory search [BETA]

# Enable during onboarding or toggle manually in .features.json, then:
python3 .agent/memory/memory_search.py "deploy failure"
python3 .agent/memory/memory_search.py --status
python3 .agent/memory/memory_search.py --rebuild

Falls back to ripgrep → grep when FTS5 index is not enabled. Index stored at .agent/memory/.index/ (gitignored).

Nightly staging cycle (cron)

# Add to crontab: runs at 03:00 daily, safe to run unattended
crontab -e
# Paste:
0 3 * * * python3 /absolute/path/to/project/.agent/memory/auto_dream.py >> /absolute/path/to/project/.agent/memory/dream.log 2>&1

auto_dream.py only does mechanical work: cluster, stage, prefilter, decay. No git commits, no network calls, no LLM reasoning.

Code examples

Python: running the staging cycle programmatically

import subprocess
import sys
from pathlib import Path

def run_dream_cycle(project_root: str) -> None:
    dream_script = Path(project_root) / ".agent" / "memory" / "auto_dream.py"
    log_path = Path(project_root) / ".agent" / "memory" / "dream.log"

    if not dream_script.exists():
        raise FileNotFoundError(f"auto_dream.py not found at {dream_script}")

    with log_path.open("a") as log_file:
        result = subprocess.run(
            [sys.executable, str(dream_script)],
            stdout=log_file,
            stderr=log_file,
            cwd=project_root,
        )

    if result.returncode != 0:
        print(f"Dream cycle exited with code {result.returncode}. Check {log_path}")
    else:
        print("Dream cycle complete.")

run_dream_cycle("/path/to/your-project")

Python: reading feature toggles

import json
from pathlib import Path

def get_features(project_root: str) -> dict:
    features_path = Path(project_root) / ".agent" / "memory" / ".features.json"
    if not features_path.exists():
        return {}
    with features_path.open() as f:
        return json.load(f)

def is_fts_enabled(project_root: str) -> bool:
    return get_features(project_root).get("fts_memory_search", False)

# Usage
if is_fts_enabled("."):
    print("FTS memory search is active")

Python: querying memory search programmatically

import subprocess
import sys
from pathlib import Path

def search_memory(project_root: str, query: str) -> str:
    search_script = Path(project_root) / ".agent" / "memory" / "memory_search.py"
    result = subprocess.run(
        [sys.executable, str(search_script), query],
        capture_output=True,
        text=True,
        cwd=project_root,
    )
    return result.stdout

hits = search_memory(".", "deploy failure")
print(hits)

Python: reading graduated lessons from lessons.jsonl

import json
from pathlib import Path

def load_lessons(project_root: str) -> list[dict]:
    lessons_path = Path(project_root) / ".agent" / "memory" / "semantic" / "lessons.jsonl"
    if not lessons_path.exists():
        return []
    lessons = []
    with lessons_path.open() as f:
        for line in f:
            line = line.strip()
            if line:
                lessons.append(json.loads(line))
    return lessons

for lesson in load_lessons("."):
    print(lesson.get("claim"), "—", lesson.get("graduated_at"))

Python: standalone harness entrypoint pattern

# adapters/standalone-python/run.py pattern
import os
from pathlib import Path

AGENT_ROOT = Path(__file__).parent.parent.parent / ".agent"
PREFERENCES = AGENT_ROOT / "memory" / "personal" / "PREFERENCES.md"
LESSONS = AGENT_ROOT / "memory" / "semantic" / "LESSONS.md"
SKILL_INDEX = AGENT_ROOT / "skills" / "_index.md"

def build_system_prompt() -> str:
    parts = []
    for path in [PREFERENCES, LESSONS, SKILL_INDEX]:
        if path.exists():
            parts.append(f"## {path.name}\n{path.read_text()}")
    return "\n\n---\n\n".join(parts)

# Pass build_system_prompt() as the system message to your LLM client
system = build_system_prompt()

Shell: install for a specific harness then verify

# Install for Cursor
./install.sh cursor /path/to/my-project

# Verify adapter file was written
ls /path/to/my-project/.cursor/rules/
# → agent-brain.mdc

# Verify brain is present
ls /path/to/my-project/.agent/
# → AGENTS.md  harness/  memory/  skills/  protocols/  tools/

Shell: switching from OpenClient to OpenClaw (breaking change in v0.6.0)

# Remove old adapter file
rm .openclient-system.md

# Re-run installer for openclaw
./install.sh openclaw /path/to/your-project

# Verify
ls .openclaw-system.md

Commits: conventional commits
Code review: critical issues only

.agent/memory/.features.json

{
  "fts_memory_search": false
}

Set fts_memory_search to true to enable FTS5 search index (requires SQLite with FTS5; most systems have it).

.agent/protocols/permissions.md

Controls what the pre-tool-call hook allows. Example pattern:

## Allowed
- Read any file in the project
- Write to .agent/memory/
- Run git status, git log, git diff

## Requires confirmation
- git push
- rm -rf
- Any network request outside localhost

## Always denied
- Modifying .agent/protocols/permissions.md without explicit user instruction

Harness-specific notes

Claude Code

Files written: CLAUDE.md, .claude/settings.json
Hook support: PostToolUse (episodic logging), Stop (session summary)

./install.sh claude-code /path/to/project
# CLAUDE.md tells Claude to load .agent/AGENTS.md at session start

Cursor

Files written: .cursor/rules/agent-brain.mdc
No hook support — call reflection tools manually:

python3 .agent/tools/memory_reflect.py

Windsurf

Files written: .windsurfrules
Same manual reflection pattern as Cursor.

Pi Coding Agent (v0.6.0+)

./install.sh pi /path/to/project
# Writes AGENTS.md and creates .pi/skills → .agent/skills symlink
# Safe alongside hermes/opencode — skips AGENTS.md overwrite if present

Standalone Python

./install.sh standalone-python /path/to/project
# Drops adapters/standalone-python/run.py — bring your own LLM client

How knowledge compounds

Session actions
    └─► episodic/ log
            └─► auto_dream.py clusters recurring patterns
                    └─► candidates staged (not committed)
                            └─► list_candidates.py → agent reviews
                                    ├─► graduate.py --rationale "..."
                                    │       └─► lessons.jsonl appended
                                    │               └─► LESSONS.md re-rendered
                                    │                       └─► future sessions load relevant lessons
                                    └─► reject.py --reason "..."
                                            └─► decision history preserved (churn visible)

Skills that fail 3+ times in 14 days are flagged for rewrite via the on_failure hook. git log .agent/memory/ is the agent's full autobiography.

Troubleshooting

Wizard didn't run after install

# Re-run manually
python3 onboard.py claude-code /path/to/project

# Or force reconfigure
agentic-stack claude-code --reconfigure

auto_dream.py exits non-zero

# Check the log
cat .agent/memory/dream.log | tail -50

# Common cause: relative path invocation — use absolute paths in crontab
python3 /absolute/path/.agent/memory/auto_dream.py

Memory search returns nothing

# Check if FTS is enabled
python3 .agent/memory/memory_search.py --status

# Rebuild the index
python3 .agent/memory/memory_search.py --rebuild

# If FTS disabled, enable in .features.json then rebuild

OpenClaw adapter not found after upgrade from v0.5.x

# Old file name was .openclient-system.md — re-run the installer
rm .openclient-system.md
./install.sh openclaw .

graduate.py refuses to run without --rationale

This is intentional — the flag is structurally required to prevent rubber-stamping:

# Wrong
python3 .agent/tools/graduate.py abc123

# Right
python3 .agent/tools/graduate.py abc123 --rationale "Pattern appears in 5 episodes, consistent with PREFERENCES.md test strategy"

Lessons.md out of sync with lessons.jsonl

python3 .agent/memory/render_lessons.py

Hand-curated content above the sentinel line in LESSONS.md is preserved; only the auto-rendered section below it is overwritten.
