| name | context-grounding |
| description | Use when a development task needs Analysis Pack, Context Manifest, context slicing, runtime audit, freshness checks, or sufficiency eval before implementation. 当任务需要深度阅读、上下文裁剪、Analysis Pack、Context Pack、allowed paths、freshness、runtime audit 或验证上下文是否足够时使用。 |
Context Grounding
目标：让 Coding Agent 只吃足够且可追踪的上下文，而不是重新从长仓库里自由探索。
Outputs
Analysis Pack: 人读分析，说明 Problem、Entry Points、Current Flow、Similar Patterns、Context Slice、Risks、Task Plan、Evidence Plan。context_manifest.json: 机器校验契约，记录 repo commit、spec version、allowed/forbidden paths、文件 hash、runtime audit。
Required References
references/analysis-pack.md: 写 Analysis Pack。references/context-manifest-contract.md: 写 context_manifest.json。references/runtime-audit.md: 检查实际读取范围。references/sufficiency-eval.md: fresh Plan Agent sufficiency eval。
Validation
python3 skills/context-grounding/scripts/validate_context_pack_static.py context_manifest.json
python3 skills/context-grounding/scripts/validate_context_freshness.py context_manifest.json --repo-root .
python3 skills/context-grounding/scripts/validate_context_runtime_audit.py context_manifest.json
python3 skills/context-grounding/scripts/run_context_sufficiency_eval.py context_manifest.json --spec spec.md
Exit Gate
只有当 static、freshness、runtime audit、sufficiency 四类检查都有结论时，Context Pack 才能标记为 ready。若任一检查不可运行，必须把 gap 写入 workflow manifest 或 evidence manifest。
