Use when the user describes a multi-step feature or refactor and you need to decide whether to handle it solo, dispatch a parallel `/fan-out`, or run a `/worktree-team` planner→generator→reviewer pipeline. Outputs a routing recommendation with the reasoning behind it.
Use whenever the user asks to apply the same operation to many independent files or components — bulk migration, batch refactor across controllers, parallel exploration of unrelated subsystems. Dispatches one subagent per file with a shared prompt template, then collects the results.
Use to toggle the safe-mode flag at .claude/safe-mode. The flag is written automatically by consecutive-failure-guard once tool failures hit FORGE_SAFE_MODE_THRESHOLD (default 5), and block-destructive.sh denies every Bash/Write/Edit while it exists. /safe-mode off clears the flag, logs the exit, and prompts /postmortem; /safe-mode on enters manually; /safe-mode status reports current state.
Run the 5-stage Token Transformation Pipeline (TRAE §5.2.2) over the current session state — Collection, Ranking, Compression, Budgeting, Assembly. Emits a concrete next-action recommendation (/compact, /lean-md, or /progress-log + fresh session) instead of a generic warning.
Audit or scaffold a CLAUDE.md against the Karpathy 4-section structure (Think Before Coding · Simplicity First · Surgical Changes · Goal-Driven Execution). Companion to /lean-md — structure audit, not size trim.
Print every policy enforcement point declared in plugins/diagnostics/registry/policies.json — id, verdict, plugin, hook event, severity, bypass — grouped by verdict. Single discoverable index of what the harness blocks, anchors, nudges, or logs at runtime.

Composable read-only audit. Pure scoring; never edits a SKILL.md. Output feeds /auto-tune-skill as a candidate selector — pipe the JSON form through jq '.skills | map(select(.score < 0.5)) | .[].path' to get the prioritized rewrite list.

Each signal contributes a sub-score in [0.0, 1.0]. Total score is a weighted sum.
| Signal | Weight | Computation |
|---|---|---|
| Edit recency | 0.25 | git log -1 --format=%ct against the SKILL.md. 1.0 if ≤30 days, linear decay to 0.0 at 365 days, then 0.0. |
| Eval coverage | 0.20 | 1.0 if a sibling evals/evals.json exists, else 0.0. |
| SSL overlay | 0.15 | (present_fields)/3 for scheduling, structural, logical in frontmatter (arXiv:2604.24026). |
| Citation freshness | 0.15 | Most recent arXiv:NNNN.NNNNN in body. 1.0 if ≤18 months old, 0.5 if ≤36 months, 0.0 otherwise. Skills with no citation get 0.5 (neutral). |
| Description budget | 0.10 | description + when_to_use total chars vs 1536 cap. 1.0 if ≤1280, linear decay to 0.0 at 1536. |
| Exclusion clause | 0.10 | 1.0 if when_to_use contains Do NOT use for (per CLAUDE.md frontmatter rule), else 0.0. |
| Helper extraction | 0.05 | 1.0 if no inline ≥10-line code block in SKILL.md body (long helpers should live in scripts/). |

/auto-tune-skill — feed --format=json | jq to surface stale candidates./ssl-audit — single-skill SSL frontmatter validation (this skill aggregates across the marketplace).git mtime. A freshly-cloned worktree resets file mtimes; the script reads commit time, not stat mtime, so this is not a problem in CI but can mislead on a cp -a mirror. Document the source repo if running outside the original clone.arXiv: reference scores 0.5 on freshness (neutral). Real skills without academic backing aren't penalized; skills with intentionally-stale citations are flagged.
