What is DocGuard?

DocGuard enforces Canonical-Driven Development (CDD) — a methodology where documentation is the source of truth, not an afterthought. AI writes the docs, DocGuard validates them.

Traditional Development	Canonical-Driven Development
Code first, docs maybe	Docs first, code conforms
Docs rot silently	Drift is tracked and enforced
Docs are optional	Docs are required and validated
One AI agent, one context	Any agent, shared context via canonical docs

DocGuard is an official GitHub Spec Kit community extension. It validates the artifacts that Spec Kit creates, ensuring your specs stay high-quality throughout the development lifecycle.

Why DocGuard?

Documentation that drifts from code is worse than no documentation — it confidently misleads humans and AI agents alike. DocGuard treats your canonical docs as an enforced contract: deterministic validators diff what the docs claim against what the code does, on every commit, with no LLM required. The full thesis (and the research behind it) lives in PHILOSOPHY.md; recent feature highlights moved below.

The field data backs the enforcement-over-instructions bet: an ETH Zurich study across 138 repos / 5,694 agent PRs found the most popular style of agent-instruction file hurts agent performance, and practitioners keep converging on the same lesson — written rules are routinely ignored; programmatic checks are what agents (and humans) actually respect. That is exactly the layer DocGuard provides: not another instructions file, but the validator suite that makes the instructions and docs verifiably true.

⚡ Quick Start

Package naming: this repo is raccioly/docguard; the published package is docguard-cli on both npm and PyPI; the installed command is docguard. Same project — the -cli suffix is just the registry name. The package runs no install scripts, so npm i -g docguard-cli --ignore-scripts is equivalent.

Node.js (npm)

# No install needed — run directly
npx docguard-cli diagnose

# Or install globally
npm i -g docguard-cli
docguard diagnose

Python (PyPI)

pip install docguard-cli
docguard diagnose

Note: The Python package is a thin wrapper that delegates to npx. Node.js 18+ is required on the system.

More ways to integrate

• pre-commit — changed-only guard on every commit:

  repos:
    - repo: https://github.com/raccioly/docguard
      rev: v0.29.0
      hooks: [{ id: docguard-guard }]   # docguard-guard-full for pre-push
  

• MCP (Claude, Cursor, any MCP client) — claude mcp add docguard -- npx -y docguard-cli mcp; 5 read-only tools (guard, score, explain, verify-claims, diagnose). Registry manifest ships in-repo (server.json, Smithery-ready).
• GitLab CI — component staged at templates/ci/gitlab-component.yml (guard/score/ci job with a SARIF artifact).
• Homebrew — brew install raccioly/tap/docguard (formula in packaging/homebrew/).

Core Workflow

# 1. Initialize docs for your project
npx docguard-cli init

# 2. Or reverse-engineer docs from existing code
npx docguard-cli generate

# 3. AI diagnoses issues and generates fix prompts
npx docguard-cli diagnose

# 4. Validate — use as CI gate
npx docguard-cli guard

# 5. Check maturity score
npx docguard-cli score

The AI Loop

diagnose  →  AI reads prompts  →  AI fixes docs  →  guard verifies
   ↑                                                       ↓
   └───────────────── issues found? ←──────────────────────┘

diagnose is the primary command. It runs all validators, maps every failure to an AI-actionable fix prompt, and outputs a remediation plan. Your AI agent runs it, fixes the docs, and runs guard to verify.

Mechanical vs. agent fixes

DocGuard splits drift into two kinds and is explicit about which is which:

Kind	Example	How it's fixed
Mechanical (deterministic)	An endpoint documented in API-REFERENCE.md that the OpenAPI spec confirms is gone	docguard fix --write deletes the row + detail block itself — no AI
Agent (needs judgment)	Rewriting an X-Ray prose section as CloudWatch; writing a new endpoint's request/response	Routed to an AI agent via diagnose / fix --doc prompts

docguard fix --write only touches docs marked <!-- docguard:generated true --> (override with --force), is idempotent, and prints exactly what changed. It never rewrites prose — that stays with the agent.

Hands-off loop (set and forget)

guard ──▶ fix --write (mechanical, auto) ──▶ guard ──▶ diagnose (agent prompts for the rest)

• CI / pre-commit: docguard hooks --type pre-commit --auto-fix installs a hook that applies mechanical fixes, re-stages the docs, then runs guard; anything left is surfaced as agent prompts.
• Agent-driven: docguard diagnose --auto scaffolds missing docs and applies mechanical fixes, then emits prompts for the content rewrites that remain.
• JSON for automation: guard/diagnose --format json include a mechanicalFixes array and tag each issue mechanical vs agent, so an agent can apply or delegate precisely.

🌱 Spec Kit Integration

DocGuard is a community extension for GitHub's Spec Kit framework. While Spec Kit focuses on creating specifications (via AI slash commands like /speckit.specify and /speckit.plan), DocGuard focuses on validating their quality.

How They Work Together

Phase	Tool	What happens
1. Initialize	specify init	Creates .specify/ directory and templates
2. Write specs	/speckit.specify	AI creates spec.md with FR-IDs, user stories
3. Validate	docguard guard	Checks spec quality (mandatory sections, FR/SC IDs)
4. Plan	/speckit.plan	AI creates plan.md with technical context
5. Validate	docguard guard	Checks plan quality (sections, structure)
6. Tasks	/speckit.tasks	AI creates tasks.md with phased breakdown
7. Validate	docguard guard	Checks task quality (phases, T-IDs)
8. Implement	/speckit.implement	AI writes code
9. Enforce	docguard guard	Final quality gate — CI/CD

What DocGuard Validates in Spec Kit Projects

• spec.md — Mandatory sections (User Scenarios, Requirements, Success Criteria), FR-xxx IDs, SC-xxx IDs
• plan.md — Summary, Technical Context, Project Structure sections
• tasks.md — Phased task breakdown (Phase 1, 2, 3+), T-xxx task IDs
• constitution.md — Detected at .specify/memory/constitution.md or project root
• Requirement traceability — FR, SC, NFR, US, AC, UC, SYS, ARCH, MOD, T IDs

Installing as a Spec Kit Extension

specify extension add docguard

This installs DocGuard's slash commands (/docguard.init, /docguard.guard, /docguard.review, /docguard.fix, /docguard.update) into your AI agent's command palette.

Usage

DocGuard ships 20 commands (the "Daily 5" + 15 situational tools, including the zero-install demo, the mcp server, and the ci pipeline gate). Six additional one-shot scaffolders are accessed via docguard init --with <name>. Seven v0.19 commands continue to work as deprecation aliases through v0.20.x — see MIGRATION-v0.20.md.

The Daily 5 — what you'll reach for 95% of the time:

Command	What It Does
init	Bootstrap a project (--wizard for interactive · --with <name> for scaffolders)
guard	Validate against canonical docs — 27 validators
diff	Show gaps between docs and code (--since <ref> for impact mode)
sync	Refresh code-truth doc sections — keeps memory always up to date
score	CDD maturity score (0-100; --diff for delta between refs)

Tools (situational, but day-to-day useful):

Command	Purpose
demo	Zero-install showcase — runs guard against a baked-in drifting fixture (npx docguard-cli demo)
diagnose	AI orchestrator — guard → emit fix prompts in one command
fix	Generate AI fix instructions for specific docs (--doc <name> --format prompt)
fix --write	Apply deterministic fixes (no AI — version bumps, counts, anchors, sections)
fix --history	Audit log of every mechanical fix applied (from .docguard/fixed.json)
generate	Reverse-engineer docs from existing codebase (--plan for AI scan) — includes auto-generated Mermaid ER diagrams from your detected schemas (Prisma/Drizzle/TypeORM/Sequelize/Django/Rails) in DATA-MODEL.md
agent	One-shot agent task graph — ordered, pre-filled code-truth, per-task verify (--format json)
explain <warning|CODE>	Paste any warning — or a finding code like SEC001 — to get the validator's docstring, fix path, and how to suppress
verify --semantic	Extract documented numbers/limits/enums (retention days, rate limits, GSI/role counts, status enums) as a task list for an agent to check against code — the semantic-drift class regex/AST can't see
verify --instructions	Audit AGENTS.md/CLAUDE.md themselves for drift: duplicate rules, never-vs-always contradictions, stale file pointers, unknown commands — plus clustered rule pairs as agent judgment tasks
feedback	Report likely false positives back to DocGuard — local-first record + a 1-click prefilled, redacted GitHub issue (zero typing)
mcp	MCP server — exposes guard/score/explain/verify/report/diagnose as native tools for Claude, Cursor, and any MCP client. Stdio: claude mcp add docguard -- npx docguard-cli mcp. Team-shared HTTP: docguard mcp --transport http --port 8585 (loopback by default; non-loopback binds require --api-key)
report	Compliance-evidence bundle for audits — guard verdict + CDD score + ALCOA+ attributes + fix history, stamped with git commit and a tamper-evident sha256 integrity hash (--format json, --out <file>). Evidence, not a gate: always exits 0
ci	Pipeline gate: guard + score in one command — never scaffolds or touches source; its only write is its own .docguard/history.jsonl (opt out: --no-history). --threshold <n> fails below a score, --fail-on-warning for strict mode, --format json for parsers
score --trend	Score trajectory from recorded ci runs — sparkline, delta, and the last 10 runs with commit stamps
memory	Per-domain accuracy headline (endpoints / entities / env / tech)
memory --diff	Drill into which specific claims don't match code
memory --pack	Write .docguard/context-pack.md — compact, code-truth-stamped session-start context for AI agents
score --diff	Drill into which checks pulled each category down
trace / trace --reverse <file>	Requirements traceability — forward AND reverse
trace --features	Per-feature spec-adherence scores (requirement coverage, task completion, task evidence, artifacts) — worst-first with fix hints
upgrade [--apply] [--pr]	Check + migrate .docguard.json schema; --pr opens a PR
watch	Live mode: re-run guard on file changes

init --with <name> scaffolders — picked at init time:

Scaffolder	What It Generates
agents	AGENTS.md, CLAUDE.md, .cursor/rules/, .github/copilot-instructions.md
hooks	Git pre-commit / pre-push hooks
ci	GitHub Actions / pipeline YAML
badge	Shields.io score badges for README
llms	llms.txt (AI-friendly summary)
publish	External doc-site config (Mintlify) — experimental

Run them solo (docguard init --with hooks) or stacked (docguard init --with agents,hooks,badge,ci).

Deprecation aliases — setup · agents · hooks · ci · badge · llms · publish · impact keep working in v0.20.x with a yellow stderr warning. audit → guard is permanent (no warning). See MIGRATION-v0.20.md.

🔍 Validators

DocGuard runs 27 automated validators on every guard check. Every one is language-aware as of v0.16 — patterns for Python (test_*.py), Rust (tests/*.rs), Go (*_test.go), Java (*Test.java), Ruby (*_spec.rb), PHP, and JS/TS all match.

#	Validator	What It Checks	Default

5	Changelog	CHANGELOG.md has [Unreleased] section	✅ On
6	Test-Spec	Tests exist per TEST-SPEC.md rules	✅ On
7	Environment	Env vars documented, .env.example exists	✅ On
8	Security	No hardcoded secrets in source code	✅ On
9	Architecture	Imports follow layer boundaries (honors config.ignore)	✅ On

21	Generated-Staleness	source=code sections match scanner output; status: draft doc age	✅ On
22	Canonical-Sync	DocGuard's own README count claims match code-truth (DocGuard repo only — N/A elsewhere)	✅ On
23	Metrics-Consistency	Hardcoded numbers match actual counts	✅ On
24	Surface-Sync	Item-level enumerable drift — names in doc tables/lists (commands, checks, etc.) match code-truth (opt-in via surfaceSync.surfaces; N/A unless configured)	✅ On
25	Diff-Suspicion	Change-driven: a doc/agent-instruction file that references code changed since the ref AND shares removed domain symbols is flagged for review (arXiv 2010.01625, F1 74.7)	✅ On

🤖 AI Agent Support

One-click MCP install

• Claude Code: claude mcp add docguard -- npx docguard-cli mcp
• Claude Desktop: download docguard-v<version>.mcpb from the latest release and drag it into Settings → Extensions — you'll be asked which project folder to analyze. No npm, no JSON editing.
• Anything MCP: DocGuard is a verified namespace on the official MCP registry (io.github.raccioly/docguard).

DocGuard works with every major AI coding agent. All canonical docs are plain markdown — no vendor lock-in.

Agent	Compatibility	Auto-Generate Config
Google Antigravity	✅	docguard agents --agent antigravity
Claude Code	✅	docguard agents --agent claude
GitHub Copilot	✅	docguard agents --agent copilot

Always-on nudge hook (Claude Code)

docguard hooks --claude            # install   (remove: docguard hooks --claude --remove)

Registers a PostToolUse hook in the project's .claude/settings.json. After the agent edits a canonical doc it is nudged to run docguard guard --changed-only; after it edits a code file the docs reference, it is nudged toward docguard impact. Merge-safe (only DocGuard's own entry is ever added/removed), throttled to one nudge per file per 30 minutes, and the hook runtime can never break a session (errors are silent by contract). Explicit opt-in — init never installs it for you.

⚡ Slash Commands

DocGuard provides AI agent slash commands for integrated workflows. Installed automatically via docguard init or specify extension add docguard:

Command	What It Does
/docguard.init	Initialize Canonical-Driven Development in a new or existing project
/docguard.guard	Run quality validation — check all 27 validators
/docguard.review	Analyze doc quality and suggest improvements
/docguard.fix	Generate targeted fix prompts for specific issues
/docguard.update	Update canonical docs after code changes — detect drift and sync documentation

.github/commands/     → GitHub Copilot
.cursor/rules/        → Cursor
.gemini/commands/     → Google Gemini
.claude/commands/     → Claude Code
.agents/workflows/    → Antigravity

---

🧠 AI Skills (Enterprise)

Beyond slash commands, DocGuard provides 4 enterprise-grade AI skills — deep behavior protocols that tell AI agents not just what to run, but how to think, validate, and iterate. Skills are modeled after Spec Kit's skill architecture.

Skill	Lines	What It Does
docguard-guard	155	6-step quality gate with severity triage (CRITICAL→LOW), structured reporting, remediation
docguard-fix	195	7-step research workflow with per-document codebase research and 3-iteration validation loops
docguard-review	170	Read-only semantic cross-document analysis with 6 analysis passes and quality scoring
docguard-score	165	CDD maturity assessment with ROI-based improvement roadmap and grade progression

Workflow Hooks

DocGuard integrates into the spec-kit workflow as an automated quality gate:

Hook	When	Behavior
after_implement	After /speckit.implement	Mandatory — always runs DocGuard guard
before_tasks	Before /speckit.tasks	Optional — reviews doc consistency
after_tasks	After /speckit.tasks	Optional — shows CDD maturity score

Orchestration Scripts

For advanced users and CI/CD pipelines, DocGuard includes bash scripts with --json output:

Script	Purpose
docguard-check-docs.sh	Discover project docs, return JSON inventory with metadata
docguard-suggest-fix.sh	Run guard, parse results, output prioritized fixes
docguard-init-doc.sh	Initialize canonical doc with metadata header

---

📁 Examples

Three real-world projects to see DocGuard in action:

Example	Scenario	What You'll See
01-express-api	Node.js API with zero docs	Cold-start: generate → instant coverage
02-python-flask	Python app with drifted docs	Drift detection: catch when docs lie
03-spec-kit-project	Full CDD + Spec Kit	Gold standard: what maturity looks like

See examples/README.md for step-by-step instructions.

🧪 Testing

Test Suite

npm test    # 33 tests across 18 describe blocks

Covers all 15 CLI commands, project type detection, compliance profiles, JSON output format, and help completeness.

CI Matrix

Node.js	OS	Status
18	ubuntu-latest	✅
20	ubuntu-latest	✅
22	ubuntu-latest	✅

Self-Validation (Dogfooding)

DocGuard runs its own guard, score, diff, diagnose, and badge commands against itself in CI — ensuring the tool passes its own checks.

🏢 Enterprise Adoption

Everything runs local or in your CI — no SaaS, no data leaving your infra. The pieces that matter at company scale:

Need	DocGuard answer
Adopt on a legacy repo without a red pipeline on day one	guard --update-baseline freezes existing findings into a committed .docguard.baseline.json; only NEW drift gates from then on (suppression always visible)
Audit trail for compliance reviews	docguard report — commit-stamped evidence bundle (guard verdict, findings by code, CDD score, ALCOA+ data-integrity attributes, fix history) with a tamper-evident sha256 integrity hash
Every CI system, not just GitHub	guard --format sarif (GitHub Code Scanning) · --format junit (GitLab, Jenkins, Azure DevOps, CircleCI) · --format json (anything else)
Trajectory, not snapshots	docguard ci records every run to .docguard/history.jsonl; score --trend shows the sparkline + delta
AI agents on the team	MCP server (stdio or team-shared HTTP) exposes guard/score/explain/verify/report/diagnose as read-only tools; agents --sync keeps the whole agent-file family drift-proof
Data-integrity framing auditors know	ALCOA+ scoring (FDA 21 CFR Part 11 / EMA Annex 11 vocabulary) built into score and report

⚙️ CI/CD Integration

Full recipes: see docs-canonical/CI-RECIPES.md for guard, auto-fix (commits mechanical fixes back to PRs), nightly sync, score-on-PR, and pre-commit configs.

GitHub Actions — Guard (most common)

name: DocGuard Guard
on: [pull_request, push]
permissions: { pull-requests: write }   # for the sticky PR comment (optional)
jobs:
  docguard:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with: { fetch-depth: 0 }
      - uses: raccioly/docguard@v0.12.0
        with:
          command: guard

On pull requests, guard mode also gives inline PR feedback (both default on):

Input	Default	Description
annotations	true	Inline ::error/::warning annotations on the PR diff, one per guard finding (capped at 50; a final notice reports how many were elided)
pr-comment	true	Sticky PR comment with the guard verdict, top findings (by code), and which canonical docs the PR's changed files impact (diff --since origin/<base>). Needs permissions: pull-requests: write; degrades to a log warning without it

Both run even when guard fails — that's when the feedback matters. Prefer native code-scanning integration? docguard guard --format sarif uploads straight to GitHub Code Scanning via github/codeql-action/upload-sarif.

GitHub Actions — Auto-Fix (commits mechanical fixes back)

name: DocGuard Auto-Fix
on: { pull_request: { types: [opened, synchronize, reopened] } }
permissions: { contents: write, pull-requests: write }
jobs:

Pre-commit Hook

npx docguard-cli hooks --type pre-commit

Workflow starters (copy directly)

Two ready-to-use templates ship with the Spec Kit extension and as standalone files:

• extensions/spec-kit-docguard/templates/github-workflows/docguard-guard.yml — mandatory CI gate
• extensions/spec-kit-docguard/templates/github-workflows/docguard-autofix.yml — PR auto-fix

✨ What's New

Highlights of the current line (v0.29 → v0.33):

• Adoption baseline — guard --update-baseline freezes a legacy repo's existing findings into a committed .docguard.baseline.json; guard/ci then gate only NEW drift, with suppression always visible. Adopt today, burn down at your own pace.
• docguard report — commit-stamped compliance-evidence bundle (guard verdict, findings by code, CDD score, ALCOA+ attributes, fix history) with a tamper-evident sha256 integrity hash. Also exposed as the docguard_report MCP tool.
• Score history + score --trend — docguard ci records every run to .docguard/history.jsonl; the trend view shows the sparkline and delta over time.
• Three machine formats for guard — --format json, --format sarif (GitHub Code Scanning), and --format junit (GitLab, Jenkins, Azure DevOps, CircleCI).
• MCP server, stdio + team HTTP — guard/score/explain/verify/report/diagnose as read-only agent tools: claude mcp add docguard -- npx docguard-cli mcp.
• Agent-file family sync — agents --sync treats AGENTS.md as canonical and regenerates CLAUDE.md / .cursor/rules / Copilot / Gemini variants with drift-proof source-hash markers.
• verify --semantic and verify --instructions — extract documented numbers/limits/enums as agent verification tasks; audit the agent-instruction files themselves for contradictions and stale pointers.
• docguard agent — one-shot ordered task graph with pre-filled code-truth, collapsing ~10 agent round-trips into one call.
