attune-author

Create and maintain dynamic, context-sensitive help for your codebase — help content that stays in sync with source and is served on demand at the right depth to whoever asks: a human reader, an IDE, or an AI coding assistant over MCP.

Not a static docs site and not a wiki. Help content is authored as a manifest of features, generated from source (concept → task → reference depths), tracked by content hash, regenerated when source drifts, and delivered progressively so readers — human or AI — get exactly the depth they asked for.

attune-help (reader) --> attune-author (authoring) --> attune-ai (full workflows)

Installation

pip install attune-author           # Core (templates, staleness)
pip install 'attune-author[ai]'     # + AI-powered doc generation
pip install 'attune-author[rag]'    # + RAG-grounded polish (see below)
pip install 'attune-author[rich]'   # + Rich CLI formatting

RAG-grounded polish (optional)

When attune-author[rag] is installed, the LLM polish pass consults existing attune-help templates via attune-rag before rewriting your generated template. It surfaces related templates as style and naming references so the polished output stays consistent with the wider ecosystem's conventions — not to copy content, but to keep headings, terminology, and structure aligned.

Grounding is on by default when the extra is installed. To disable per-invocation:

attune-author generate my-feature --no-rag

To disable globally (e.g. in CI for deterministic output):

ATTUNE_AUTHOR_RAG=0 attune-author generate my-feature

Without the [rag] extra installed, attune-author proceeds as before — no behavior change.

Quick Start

# Initialize help system in your project
attune-author init

# Check which templates are stale
attune-author status

# Generate templates for a feature
attune-author generate security-audit

# Regenerate all stale templates
attune-author regenerate

Python API

from attune_author import load_manifest, check_staleness

# Load your project's feature manifest
manifest = load_manifest(".help/features.yaml")

# Check which features have stale documentation
report = check_staleness(".help/")
for feature in report.stale:
    print(f"  {feature.name}: {feature.reason}")

Features

• Progressive-depth templates -- Every feature gets a concept (overview), task (how-to), and reference (API) view, plus optional problem-shaped (error, warning, troubleshooting, faq) and guidance-shaped (quickstart, tip, note, comparison) kinds
• Context-sensitive delivery -- Readers fetch only the depth they need via attune-help; AI assistants pull the right slice through the MCP author_lookup tool
• Staleness detection -- Source-hash drift is tracked in template frontmatter; drift triggers regeneration on the next regenerate or post-commit hook
• Grounded generation -- Templates are rendered from the actual source AST (signatures, defaults, raises with diagnostic messages, dataclass fields, Literal enums, @property accessors, module-level string constants), optionally polished by an LLM against a strict source-info anchor that separates prose from verbatim facts
• Bulk maintenance -- Regenerate every stale feature in one command, or let the post-commit hook do it for you scoped to files that actually changed
• CLI -- attune-author for all operations
• MCP server -- Six tools (author_init, author_status, author_generate, author_maintain, author_lookup, author_docs) that make every CLI capability callable by Claude Code and any other MCP client

MCP Integration

To make attune-author available to Claude Code as tools, add this to .mcp.json in your project:

{
  "mcpServers": {
    "attune-author": {
      "command": "uv",
      "args": ["run", "python", "-m", "attune_author.mcp.server"]
    }
  }
}

Then ask Claude things like "are my help templates up to date?" or "regenerate the stale ones" — it will call the corresponding MCP tools directly.

Automation

Ship an always-fresh help tree by wiring up the post-commit hook:

git config core.hooksPath .githooks   # one-time setup
# or: make setup   (also installs dev deps)

After each commit the hook diffs what changed, matches the files against your manifest, and regenerates only the affected templates.

Development

make setup        # Install dev deps + configure git hooks
make test         # Run the full test suite
make lint         # ruff check
make status       # Check template staleness
make regenerate   # Regenerate stale templates
