Project Skill Audit

Overview

Audit the project's real recurring workflows before recommending skills. Prefer evidence from memory, rollout summaries, existing skill folders, and current repo conventions over generic brainstorming.

Recommend updates before new skills when an existing project skill is already close to the needed behavior.

When to Use

• When the user asks what skills a project needs or which existing skills should be updated.
• When recommendations should be grounded in project history, memory files, and local conventions.

Workflow

1. Map the current project surface. Identify the repo root and read the most relevant project guidance first, such as AGENTS.md, README.md, roadmap/ledger files, and local docs that define workflows or validation expectations.

2. Build the memory/session path first. Resolve the memory base as $CODEX_HOME when set, otherwise default to ~/.codex. Use these locations:

   • memory index: $CODEX_HOME/memories/MEMORY.md or ~/.codex/memories/MEMORY.md
   • rollout summaries: $CODEX_HOME/memories/rollout_summaries/
   • raw sessions: $CODEX_HOME/sessions/ or ~/.codex/sessions/

3. Read project past sessions in this order. If the runtime prompt already includes a memory summary, start there. Then search MEMORY.md for:

   • repo name
   • repo basename
   • current cwd
   • important module or file names Open only the 1-3 most relevant rollout summaries first. Fall back to raw session JSONL only when the summaries are missing the exact evidence you need.

4. Scan existing project-local skills before suggesting anything new. Check these locations relative to the current repo root:

   • .agents/skills
   • .codex/skills
   • skills Read both SKILL.md and agents/openai.yaml when present.

5. Compare project-local skills against recurring work. Look for repeated patterns in past sessions:

   • repeated validation sequences
   • repeated failure shields
   • recurring ownership boundaries
   • repeated root-cause categories
   • workflows that repeatedly require the same repo-specific context If the pattern appears repeatedly and is not already well captured, it is a candidate skill.

6. Separate new skill from update existing skill. Recommend an update when an existing skill is already the right bucket but has stale triggers, missing guardrails, outdated paths, weak validation instructions, or incomplete scope. Recommend a new skill only when the workflow is distinct enough that stretching an existing skill would make it vague or confusing.

7. Check for overlap with global skills only after reviewing project-local skills. Use $CODEX_HOME/skills and $CODEX_HOME/skills/public to avoid proposing project-local skills for workflows already solved well by a generic shared skill. Do not reject a project-local skill just because a global skill exists; project-specific guardrails can still justify a local specialization.

Session Analysis

1. Search memory index first

• Search MEMORY.md with rg using the repo name, basename, and cwd.
• Prefer entries that already cite rollout summaries with the same repo path.
• Capture:
  • repeated workflows
  • validation commands
  • failure shields
  • ownership boundaries
  • milestone or roadmap coupling

2. Open targeted rollout summaries

• Open the most relevant summary files under memories/rollout_summaries/.
• Prefer summaries whose filenames, cwd, or keywords match the current project.
• Extract:
  • what the user asked for repeatedly
  • what steps kept recurring
  • what broke repeatedly
  • what commands proved correctness
  • what project-specific context had to be rediscovered

3. Use raw sessions only as a fallback

• Only search sessions/ JSONL files if rollout summaries are missing a concrete detail.
• Search by:
  • exact cwd
  • repo basename
  • thread ID from a rollout summary
  • specific file paths or commands
• Use raw sessions to recover exact prompts, command sequences, diffs, or failure text, not to replace the summary pass.

4. Turn session evidence into skill candidates

• A candidate new skill should correspond to a repeated workflow, not just a repeated topic.
• A candidate skill update should correspond to a workflow already covered by a local skill whose triggers, guardrails, or validation instructions no longer match the recorded sessions.
• Prefer concrete evidence such as:
