SkillSpector: 4 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 →
- medium Excessive Agency · line 4 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- medium Agent Snooping · line 26 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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 | $0.00089 | $0.01634 |
| Opus 5.5 | $0.00036 | $0.00654 |
| Sonnet 5.5 | $0.00018 | $0.00327 |
| Haiku 4.5 | $0.00009 | $0.00163 |
Grade A, and why
new-skill 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
New Skill
A harness for adding one skill to this repository. It sequences three existing
instruments — Archcore, skill-creator, /review-and-release — and fills the gap
between them: skill-creator writes portable skills, this repo ships plugin skills,
and the two disagree on frontmatter, packaging, and file layout.
Run the steps in order. Step 1 is the only one that questions the user.
Step 0: Ground in the repo's rules
Before asking anything, read what already binds:
mcp__archcore__search_documentswithcontent: "skill command naming"— thenget_documenton.archcore/conventions/project-stack.rule.md. It fixes the file layout, the frontmatter fields, and the kebab-case naming rule.ls skills/— check no skill already covers the requested job. A near-duplicate is a reason to extend an existing skill instead, and a reason to say so before Step 1.- Read two or three existing
SKILL.mdfiles closest in shape to the request. They are the style baseline —skills/recap/SKILL.mdfor a short one,skills/compatibility-audit/SKILL.mdfor one withreferences/andscripts/.
Step 1: Collect the brief
Ask the user. Batch these into one question widget where the host offers one; otherwise one message per question, most important first. Recommend an answer for every question.
| # | Question | Recommended default |
|---|---|---|
| 1 | What does the skill do, and what are 2–3 concrete invocations of it? | — the user must supply this |
| 2 | What phrasings should trigger it? | derived from answer 1; confirm the list |
| 3 | model: haiku, sonnet, or opus? |
sonnet; haiku for a mechanical skill under ~60 lines |
| 4 | A slash command in commands/? |
yes when the skill is an action the user fires at a moment; no when it is domain expertise the model picks up from the description |
| 5 | Bundled scripts/, references/, or assets/? |
none — 5 of 20 skills carry nothing but SKILL.md |
| 6 | Original text, or a port of something external? | original; a port switches on the license track in Step 3 |
| 7 | Output language | English, unless the skill's subject is Russian text |
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.

new-skill is a skill published in the GitHub repository ivklgn/ai-kit (12 stars, last pushed 1mo ago), licensed MIT. It adds 89 tokens to every session and 1,634 once invoked, about $0.0004 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 2026-09-05.
