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 48 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 | $0.00071 | $0.04370 |
| Opus 5 | $0.00036 | $0.02185 |
| Sonnet 5 | $0.00014 | $0.00874 |
| Haiku 4.5 | $0.00007 | $0.00437 |
Grade A, and why
golden-truth 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 6d 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.

Golden gospel-truth verification — how to change the golden corpus without codifying lies
This skill is agent-agnostic: a plain-markdown runbook. Claude Code invokes it as a skill; Codex or any other CLI agent can be pointed at this file directly.
North star
The golden Q→A corpus is the gospel every eval round is judged against. A wrong agent answer costs one verdict; a wrong golden silently corrupts every future round, every A/B, every re-judge — and a golden "corrected" from thin evidence is worse than the error it replaced, because it now carries the authority of a review. Therefore:
Never change gospel from a single source class. Live-probing the corpus, or reading one docs page, is discovery — not verification. Gospel changes require multi-source triangulation across independent source classes, and disputed facts are encoded as disputes, never pinned.
This skill governs ANY change to judge-facing gospel — question, golden.answer,
golden.keyFacts, golden.avoid, golden.notes, tags.freshness, tags.trap — and to the
judge-blind truth block that carries its provenance. The corpus is owned: edits land
directly in the per-case file eval/qa/corpus/battery/<category>/<id>.json, reviewed like
code. The CI gospel-change lint (eval/qa/lint-corpus.mjs, diff-aware against the merge
base) refuses any judge-facing change whose truth.verified did not change in the same diff
with non-empty evidence + rootCause — that lint is the successor to the retired
override-file enforcement, and it moves the check from compile-time bookkeeping to the moment
of change.
The same evidence bar applies to a separately frozen provenance-bearing suite when its contract invokes this skill. Keep that suite in its contract-owned file. Do not compile it into the battery or existing routing lanes. Evaluation lanes never merge.
Step 1 — classify the truth domain (this picks the verification standard)
| Domain | What gospel means | Examples |
|---|---|---|
| real-world / protocol | Authoritative primary sources + source code. The corpus/aggregators may lag or be wrong — that's an improvements/ finding, never an excuse to weaken the golden. |
RPC limits, CLI commands, SEP semantics, build targets |
| corpus-grounded | What the live community corpora (Scout, Lumenloop) support NOW, cross-checked against the real world. Distinguish real-world-confirmed from corpus-only (in the aggregator, no external footprint). Corpus-only facts may appear in goldens but must be labeled so graders treat them as source-relative. A corpus-vs-world contradiction → improvements/ finding + grade leniently on both sides. |
Regional community events, builder directories, project records |
| freshness-sensitive | A behavior, never a pinned value. Point-in-time figures require an asOf date in the golden text itself, tags.freshness: "scheduled", and a truth.reverifyBy date. |
SCF amounts, country counts, versions, rosters |
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.

golden-truth is a skill published in the GitHub repository stellar-experimental/stellar-raven (6 stars, last pushed today), licensed Apache-2.0. It adds 71 tokens to every session and 4,370 once invoked, about $0.0004 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 2026-08-31.
