# AGENTS.md

Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.

## Overview

This is the authoritative instruction file for agents working in this repository. Preserve the project-specific rules below while applying behavioral guidelines and platform-specific conventions.

For local planning, backlog status, and current task handoffs, consult `docs/plans/start-here.md` (a local-only, gitignored planning file; if absent on fresh clones, start directly with `work-intake`).

## The Iron Laws & Critical Constraints

1. **Adversarial Reasoning Before Agreement**:
   No significant architecture decision, schema design, code refactor, deletion plan, or migration proposal may be accepted without an adversarial pass first. Agreement must be earned; challenge premises and identify critical assumptions.
2. **Destructive Action & Skill Deletion Guard**:
   Never delete a skill directory, its `SKILL.md`, or its evals because you believe it is redundant, absorbed, consolidated, or superseded. Skill deletions are hard-gated and require explicit user instructions naming the exact path.
3. **Cryptographic Human Gates (CIBA/RAR Lineage)**:
   Three pipeline transitions are cryptographic: spec approval (`Gate 1`), worktree exit review (`Gate 3`), and task closure (`DONE`). Only an out-of-band OpenSSH signature from a human-held key can advance them. Agents must never run signing commands, manipulate keys, or synthesize approval proofs.
4. **Hub-First Architecture & Loose Coupling**:
   Shared resources reside at plugin roots (`plugins/<plugin>/scripts/`, etc.) as canonical authorities and are symlinked into skill spokes via `symlink_manager.py`. Installed skills in `.agents/` must be self-contained and dereferenced.
5. **Verifier Sovereignty & Proposal Mode**:
   Implementation agents cannot modify acceptance tests, evaluation baselines, or verification scripts. Pre-execution verifier hashes are locked. In Stage 1 (`PLAN`), workspace files are strictly read-only.
6. **Config-Driven Constants Over Hardcoding**:
   Never introduce magic string literals or answer sequences. All domain constants must be imported from `constants.py`. SQL queries must use `?` bind parameters.
7. **Three-Attempt Maximum & Map Debt Logging**:
   Autonomous repair attempts are capped at 3. Every friction event must update the map (playbooks, rules, references), log `Status: RESOLVED` in `references/map-debt.md` if fixed inline, or record an open debt entry if deferred.

## Quick Start & Verification Tooling

Run standard deterministic verification scripts to validate compliance:

```bash
# Audit individual or repository skills
python3 plugins/agent-scaffolders/scripts/audit_skill.py <skill-path> --mode source

# Audit sub-agent specifications
python3 plugins/agent-scaffolders/scripts/audit_sub_agent.py plugins --all

# Audit rule policy invariants
python3 plugins/agent-scaffolders/scripts/audit_rule.py plugins --all

# Audit repository symlink health
python3 .agents/skills/symlink-manager/scripts/symlink_manager.py audit

# Synchronize registered plugins and enforce retention
python3 plugins/plugin-manager/scripts/sync_with_inventory.py
```

## Pre-Completion Verification Gate

Before claiming any task is complete, emit this verification block verbatim:

```
PRE-COMPLETION GATE:
  Capability check: Did I verify whether an existing repo capability was intended for this task? [YES/NO]
  1. Did any existing capability fail, get bypassed, or get manually replaced?  [YES/NO - 1 line if YES]
  2. Did I guess, assume, or get corrected on a repeatable process?              [YES/NO - 1 line if YES]
  3. Did I notice something the next agent will hit again if not fixed?          [YES/NO - 1 line if YES]

If any YES: action taken -> FIX / MAP_DEBT / ESCALATE
```
