Code Gap Sweeping

Code Gap Sweeping

Use this skill to run a repeatable cross-repo gap scan and convert findings into concrete follow-up actions.

Workflow

1. Run the gap sweep script across one or more local repos.
2. Review severity-ranked findings (critical, high, medium).
3. Route each finding into the smallest existing skill lane that can fix it.
4. Emit machine-readable evidence for admission, planning, and release notes.
5. For repeated multi-repo operations, generate a deterministic repo-family command matrix.

Canonical Run

python3 "$CODEX_HOME/skills/code-gap-sweeping/scripts/code_gap_sweep.py" \
  --repo "<PRIVATE_REPO_A>=/path/to/<PRIVATE_REPO_A>" \
  --repo "<PRIVATE_REPO_B>=/path/to/<PRIVATE_REPO_B>" \
  --since-days 14 \
  --json-out /tmp/code-gap-sweep.json

One-command sweep for all repos under a workspace root:

python3 "$CODEX_HOME/skills/code-gap-sweeping/scripts/code_gap_sweep.py" \
  --repos-root "$env:USERPROFILE\\Documents\\GitHub" \
  --exclude-repo "docs" \
  --since-days 14 \
  --json-out /tmp/code-gap-sweep-all.json

Working-tree focused sweep during active local edits:

python3 "$CODEX_HOME/skills/code-gap-sweeping/scripts/code_gap_sweep.py" \
  --repo "skill-arbiter=." \
  --diff-mode working-tree \
  --json-out /tmp/code-gap-sweep-working-tree.json

Full pipeline matrix for repo families (repo_a/repo_b/repo_c/repo_d):

python3 "$CODEX_HOME/skills/code-gap-sweeping/scripts/repo_family_pipeline.py" \
  --repo "<PRIVATE_REPO_A>=/path/to/<PRIVATE_REPO_A>" \
  --repo "<PRIVATE_REPO_B>=/path/to/<PRIVATE_REPO_B>" \
  --repo "<PRIVATE_REPO_C>=/path/to/<PRIVATE_REPO_C>" \
  --repo "<PRIVATE_REPO_D>=/path/to/<PRIVATE_REPO_D>" \
  --family "<PRIVATE_REPO_A>=repo_a" \
  --family "<PRIVATE_REPO_B>=repo_b" \
  --family "<PRIVATE_REPO_C>=repo_c" \
  --family "<PRIVATE_REPO_D>=repo_d" \
  --since-days 14 \
  --json-out /tmp/repo-family-pipeline.json \
  --bash-out /tmp/repo-family-pipeline.sh

Scope Boundary

Use this skill when the primary task is detecting and prioritizing implementation gaps across repositories.

Do not use this skill for:

1. Skill install/quarantine decisions (use skill-arbiter-lockdown-admission).
2. Skill discovery portfolio curation (use skills-discovery-curation).
3. Repo-specific deep debugging where a dedicated repo skill exists.

Gap Contracts

The script detects deterministic gap categories:

1. tests_missing: code changed without corresponding test changes.
2. docs_lockstep_missing: behavior-impacting files changed without docs updates.
3. todo_fixme_added: newly introduced TODO/FIXME markers in the patch window.
4. release_hygiene_missing: release-impacting changes without pyproject.toml + CHANGELOG.md updates.

Triage Mapping

Route findings consistently:

1. tests_missing -> repo-specific execution/test lane.
2. docs_lockstep_missing -> docs-alignment-lock.
3. todo_fixme_added -> repo-specific cleanup lane, then re-sweep.
4. release_hygiene_missing -> skill-arbiter-release-ops.

Output

JSON report includes:

• scan metadata (generated_at, since_days, repo list)
• per-repo findings with severity and evidence
• aggregate counters by category and severity
• suggested skill lanes for remediation

Loopback

If this lane is unresolved, blocked, or ambiguous:

1. Capture the JSON report path and unresolved findings.
2. Route back through $skill-hub for chain recalculation.
3. Resume only after the updated chain returns a deterministic next step.
