SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 23 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.00571 |
| Opus 5 | $0.00028 | $0.00285 |
| Sonnet 5 | $0.00011 | $0.00114 |
| Haiku 4.5 | $0.00006 | $0.00057 |
Grade A, and why
rudder-workspace-hygiene-maintainer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rudder Workspace Hygiene Maintainer
Make workspace cost visible and reclaim only space that is both proven safe and explicitly authorized.
Exclusive Outcome
AUDIT: read-only inventory and classified cleanup candidates.CLEANED: exact authorized targets removed, with reclaimed space and post-cleanup health reported.BLOCKED: safe classification or required cleanup authority is missing.
An audit is always allowed. Cleanup is allowed only for exact targets covered by the user's request.
Protected By Default
Never delete or rewrite the main checkout; dirty, unmerged, locked, or active
worktrees; source or user-created data; ~/.rudder instances and databases;
global caches; unrelated project state; or logs still being written before
identifying and handling their producer.
Do not use broad unresolved globs, inferred environment variables, or recursive deletion against a workspace root.
Audit
Run the bundled read-only helper first:
.agents/skills/maintainer/rudder-workspace-hygiene-maintainer/scripts/audit-workspace.sh
Add --sizes only when a slower serial disk scan is worthwhile.
Gross directory size is not reclaimable space. For every candidate, classify: registered worktree and branch; main/current/locked state; dirty/unmerged state; active repo-owned process; merge ancestry or other recoverability proof; generated versus user data; and exact expected reclaim.
Process reports must be scoped to registered Rudder worktree roots or an exact Rudder-owned signature. Report only redacted PID, PPID, elapsed time, RSS, executable, and owner; never dump full argv that may contain tokens.
Cleanup
- Resolve exact absolute targets.
- Confirm each target is within the user's authorized scope.
- Stop or fix active producers before rotating/removing their output.
- Prefer repository-aware or recoverable operations.
- Remove only classified generated artifacts or proven-safe worktrees.
- Re-run the audit and a lightweight health check.
- Report target, reason, bytes reclaimed, and recoverability.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rudder-workspace-hygiene-maintainer is a skill published in the GitHub repository Undertone0809/rudder (288 stars, last pushed today), licensed Apache-2.0. It adds 55 tokens to every session and 571 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
