# ContextDocs

> AGENTS-first AI IDE context management for Claude Code, OpenCode, Codex CLI, and Gemini CLI. A Claude Code plugin that generates, maintains, and audits canonical `AGENTS.md` plus thin bridge files (`CLAUDE.md`, `.cursorrules`, `.github/copilot-instructions.md`, `.windsurfrules`, `.clinerules`, `GEMINI.md`) using the Signal Gate principle — only what agents cannot discover on their own. ContextDocs keeps files lean with automatic line budgets (`AGENTS.md` <120, `CLAUDE.md` <80, other bridges <60), enforces freshness with Context Guard hooks, scores health 0–100, and promotes MEMORY.md patterns into CLAUDE.md. Pure Markdown, zero runtime dependencies. For public-facing documentation (README, CHANGELOG, ROADMAP), see [PitchDocs](https://github.com/littlebearapps/pitchdocs).

- [SKILL.md](./SKILL.md): Root-level skill manifest for directory submissions — plugin overview, installation, 3 commands, and AGENTS-first output model with line budgets

## Docs

- [README](./README.md): Project overview, Signal Gate value proposition, quick start (under 60 seconds), comparison table (vs manual vs generic AI), commands with "Why It Matters", cross-tool discovery table for AGENTS-first context across 8 AI tools
- [AGENTS.md](./AGENTS.md): Cross-tool AI context — AGENTS-first architecture, 2 agents, 3 skills inventory, 3 commands, 4 rules, 6 hooks with descriptions (Codex CLI, OpenCode, Gemini CLI format)
- [CLAUDE.md](./CLAUDE.md): Claude Code project context — plugin architecture, Australian English conventions, AGENTS-first modification guide, key files, PitchDocs relationship
- [Docs Hub](./docs/README.md): Documentation index linking all guides, quick links to README/Contributing/Changelog/Support, and skills reference

## Guides

- [Getting Started](./docs/guides/getting-started.md): Install ContextDocs, bootstrap canonical `AGENTS.md` plus bridge files with line budgets, verify health (0–100 across 6 dimensions), set up Context Guard hooks, keep context fresh with update/promote/audit
- [Troubleshooting](./docs/guides/troubleshooting.md): Content filter errors (HTTP 400) with fetch commands, Signal Gate filtering issues, Context Guard hooks not triggering, stale context files, MEMORY.md promotion, cross-tool compatibility matrix, FAQ (origin, PitchDocs relationship, Signal Gate explained)

## Agent

- [Context Updater](./.claude/agents/context-updater.md): Autonomous agent that updates stale AI context files with an AGENTS-first workflow — launched by hooks, edits shared context in `AGENTS.md`, then refreshes only affected bridge files. Capped at 10 turns, no internet access (Claude Code only)
- [Docs Freshness](./.claude/agents/docs-freshness.md): Read-only documentation freshness checker — detects stale docs, version mismatches, missing files, suggests PitchDocs commands to fix. Capped at 8 turns, enforces read-only via disallowedTools (PitchDocs, Claude Code only)

## Skills

- [AI Context](./.claude/skills/ai-context/SKILL.md): AGENTS-first AI IDE context generation with Signal Gate — canonical `AGENTS.md`, thin bridge files, init/update/promote/audit lifecycle, automatic line budgets, AGENTS.md spec tracking
- [AI Context Reference](./.claude/skills/ai-context/SKILL-reference.md): Companion reference for Claude Code — complete agent frontmatter catalogue (13 fields), skill frontmatter catalogue (11 fields), variable substitution, dynamic context injection, bundled resource patterns, agent memory directories, AGENTS-first bridge architecture, CLAUDE.md advanced features (@import, directory walking, claudeMdExcludes, managed policy), rules system, plugin system
- [Context Guard](./.claude/skills/context-guard/SKILL.md): Context Guard hook installation — two-tier enforcement (session-end nudge + pre-commit guard), SessionStart health check, post-commit drift detection, structural change reminders, content filter protection, companion reference for 17 hook events, Untether compatibility (Claude Code only)
- [Context Guard Reference](./.claude/skills/context-guard/SKILL-reference.md): Companion reference for Claude Code hooks — complete event catalogue (17 events with decision control), 4 handler types (command, http, prompt, agent), advanced features (async, once, timeout, matcher, updatedInput, CLAUDE_ENV_FILE), settings.json schema, stability notes
- [Context Verify](./.claude/skills/context-verify/SKILL.md): Context file validation — line budget compliance, discoverable content detection, stale path scanning, @import path validation, rule path-scope and symlink validation, .mcp.json structure validation, agent memory directory hygiene, plugin manifest completeness, AGENTS-to-bridge consistency, MEMORY.md drift, aggregate context load monitoring (per-tool token estimates), 0–100 health scoring with CI integration (`--min-score` enforcement)

## Commands

- [/contextdocs:ai-context](./commands/ai-context.md): Generate lean AGENTS-first AI IDE context using Signal Gate — supports init (bootstrap), update (incremental drift patching), promote (MEMORY.md → CLAUDE.md), audit (staleness check), and per-tool generation (claude, agents, cursor, copilot, windsurf, cline, gemini)
- [/contextdocs:context-guard](./commands/context-guard.md): Install, uninstall, or check status of Context Guard hooks — two-tier freshness enforcement so stale context files get caught before they waste tokens (Claude Code only)
- [/contextdocs:context-verify](./commands/context-verify.md): Score context file health 0–100 across 6 dimensions (line budget, signal quality, path accuracy, bridge consistency, freshness, context load) with 13 checks including .mcp.json, agent memory, and plugin manifest — CI integration with `--min-score` threshold
