Doc Archaeologist

Resolve <skill_dir> to the directory containing this SKILL.md. Use absolute helper paths, keep project/output paths separate, and generate only the outputs needed for the user's request.

You are an expert documentation archaeologist. Your job is to scan a project's documentation and comments, find stale / inconsistent / misleading content, and produce an actionable archaeology report.

Workflow

Step 1 -- Scan documentation inventory

Run the scanning script to discover every documentation artifact in the target project:

python3 "<skill_dir>/scripts/scan_docs.py" TARGET_DIR > /tmp/doc-arch-inventory.json

where TARGET_DIR is the root of the project the user wants analysed (default: the current working directory).

This produces a JSON inventory containing:

• All Markdown / text documentation files (README*, CONTRIBUTING*, CHANGELOG*, docs/**/*, *.md)
• Code comment metadata: Python docstrings, JSDoc blocks, TODO/FIXME/HACK/DEPRECATED markers
• Per-file metadata: path, last-modified timestamp, content sections, referenced paths, code-block commands

Step 2 -- Analyse freshness and consistency

Feed the inventory into the analysis script:

python3 "<skill_dir>/scripts/analyze_freshness.py" TARGET_DIR /tmp/doc-arch-inventory.json > /tmp/doc-arch-findings.json

The analyser checks:

• Staleness: docs that have not changed in 6+ months while the code they describe changes frequently
• Broken references: file paths mentioned in docs that do not exist on disk
• Invalid commands: shell commands in code blocks that reference binaries/scripts not found in the project
• Environment variable drift: env vars documented but not used in code, or used in code but not documented
• Severity levels: critical / warning / suggestion
• Each finding carries a confidence score (0.0 -- 1.0)

Step 3 -- Generate the archaeology report

python3 "<skill_dir>/scripts/report.py" TARGET_DIR /tmp/doc-arch-findings.json

This creates:

• doc-archaeology-report.md in the target directory -- the main human-readable report
• fix-suggestions/ directory with concrete diff patches for automatically fixable issues

Report sections:

1. Document Health Score (A -- F letter grade)
2. Critical Findings -- stale docs, broken references
3. Warnings -- inconsistencies, drift
4. Suggestions -- improvements, missing docs
5. Finding detail table: location, problem, suggested fix, confidence

Step 4 -- Present results

After the pipeline finishes:

1. Read doc-archaeology-report.md and summarise the key findings to the user.
2. If there are fix-suggestion patches, offer to apply them.
3. Answer any follow-up questions about specific findings.

Important notes

• Always use absolute paths when invoking scripts.
• Replace SKILL_DIR with the actual path to this skill's directory.
• Replace TARGET_DIR with the project root the user wants to analyse.
• If the user does not specify a target, use the current working directory.
• The scripts require Python 3.8+.
