Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, 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 →

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 | $0.00041 | $0.00965 |
| Opus 5.5 | $0.00016 | $0.00386 |
| Sonnet 5.5 | $0.00008 | $0.00193 |
| Haiku 4.5 | $0.00004 | $0.00097 |
Grade A, and why
curator-evolution 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 1mo 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Curator Evolution
Hermes Curator Evolver starts from evidence and keeps mutation guarded. Reports and proposals are review artifacts. auto-run can make skills actually improve, but only through low-risk bounded managed blocks, reference spillover for bulky evidence, and guarded apply.
Interpretation Checklist
- Separate evidence from conclusions.
- Repeated tool errors suggest a possible missing pitfall or verification step in a skill.
- Repeated skill reads suggest the skill is active and worth keeping discoverable.
- A single failure is not enough evidence to rewrite a skill.
- If the skill was correct but the agent ignored it, improve triggers/descriptions only when evidence repeats.
- Candidate search is advisory; embedding/reranker models only find candidates and do not decide edits.
backfill-sessionsreads current Hermesstate.dbsessions through the read-onlySessionDBAPI and retains explicit legacysession_*.jsonsupport; it is model-free and does not mutate skills.auto-run --semantic-candidatesand--rerank-candidatesare explicit opt-ins that only reorder evidence-eligible candidates.- Guarded apply requires approval, backup, verifier/validation pass, and rollback.
auto-runmutates only when both--apply-low-riskand--approve-auto-applyare set.- Even with write flags, unattended auto-apply writes only local agent-created skills. Official/bundled skills (
.bundled_manifest), hub-installed skills (.hub/lock.json), plugin-provided skills,skills.external_dirs, pinned skills, and unknown sources are skipped. - Core-name allowlists only operate inside that local agent-created source boundary; they do not override provenance.

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.

curator-evolution is a skill published in the GitHub repository pingchesu/hermes-curator-evolver (49 stars, last pushed 25d ago), licensed MIT. It adds 41 tokens to every session and 965 once invoked, about $0.0002 per session on Opus 5.5. 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.
