skill(blog): codex prompt should discover paths, not trust examples#645
Merged
Conversation
Two edits to .claude/skills/blog/SKILL.md and .agents/skills/blog/SKILL.md (kept in sync): 1. Phase 4 source-code audit step — instruct the auditor to discover the repo layout first via `gh api repos/<org>/<repo>/git/trees/ main?recursive=1` before assuming any path. Names the example-paths- are-stale failure mode explicitly (`langchain_runcycles/...` vs `src/langchain_runcycles/...`). 2. Phase 9a codex prompt template — replace the prescribed `gh api repos/<org>/<repo>/contents/...` example (which codex typically cannot shell to under read-only sandbox) with explicit instructions to discover paths and tell codex its read-only sandbox blocks `gh` calls, so it should route through its GitHub connector. Triggered by codex's open question in the v0.2.0 LangChain runcycles review (PR #644): "Should the source-path references in the review prompt be updated from `src/langchain_runcycles/...` to `langchain_runcycles/...`?" — same class of fragility the skill's own source-audit clause was meant to catch.

Summary
Small skill correctness fix triggered by codex's open question on PR #644 (LangChain
cost_fnpost review).Codex flagged that example file paths in the source-audit prompt (
src/langchain_runcycles/...) didn't match the package's actual layout (langchain_runcycles/...— nosrc/prefix). The skill currently encourages prescribed-path lookups, which fail silently when packages restructure or use different conventions.Two surgical edits to both
.claude/skills/blog/SKILL.mdand.agents/skills/blog/SKILL.md(kept in sync):1. Phase 4 source-code audit step
Now tells the auditor to discover the repo layout first via
gh api repos/<org>/<repo>/git/trees/main?recursive=1before assuming any path. Names the failure mode explicitly with the LangChain runcycles example.2. Phase 9a codex prompt template
Replaces the prescribed
gh api repos/<org>/<repo>/contents/...example (which codex's read-only sandbox typically cannot shell to anyway) with explicit instructions to:ghshell calls; it routes through its internal GitHub connector insteadWhy this is small but useful
This is exactly the class of trap the skill's own source-audit clause was designed to catch — assume verbatim source-of-truth at face value, miss the underlying state drift. Codex caught it in PR #644 and the skill now bakes the lesson in.
