Agent Skills: Module Source Coverage

Module Source Coverage

Triggers & routing

• Trigger: module coverage, source coverage, tutorial grounding, 模块覆盖, 来源覆盖.
• Use when: source-tutorial 的 C2，已有 outline/module_plan.yml，需要确认每个模块都能回指到 sources。
• Skip if: module plan 或 source ingest 不完整。
• Network: none.
• Guardrail: 只做 grounding audit，不写教程正文。

Builds outline/source_coverage.jsonl, one coverage record per module.

Inputs

• outline/module_plan.yml
• sources/index.jsonl
• sources/provenance.jsonl

Output

• outline/source_coverage.jsonl

Contract

Each module record must include:

• module_id
• module_title
• source_ids and/or explicit gaps

Plus exactly one corpus-reconciliation record (record_type: corpus_reconciliation, no module_id) listing ingested_source_ids, attributed_source_ids, and unused_source_ids, with an explicit gaps entry whenever a source was ingested but used by no module. A per-module audit alone cannot surface a source that contributed to zero modules, so this record keeps an unused source explicit instead of silently dropped.

Script boundary

scripts/run.py should:

• score module-to-source relevance
• choose a small source set per module
• record explicit grounding gaps when coverage is weak
• append the corpus-reconciliation record so unused ingested sources are flagged

Keep text matching and snippet scoring in shared tutorial tooling, not in the wrapper.

Acceptance

• outline/source_coverage.jsonl exists
• every module appears exactly once
• exactly one corpus_reconciliation record accounts for every ingested source
• missing grounding is explicit instead of silent

Non-goals

• context pack assembly
• tutorial prose
