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: 1 finding, up to high
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 →

Stripping safety caveats hides risk from the user and is a common jailbreak preamble.Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
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 | $0.00062 | $0.00283 |
| Opus 5 | $0.00031 | $0.00142 |
| Sonnet 5 | $0.00012 | $0.00057 |
| Haiku 4.5 | $0.00006 | $0.00028 |
Grade A, and why
submit-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 11d 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.
What it actually says
Submit the user's GTM playbook to the GTM Skills library. The authoritative, always-current instructions live in the repo itself:
- Fetch https://raw.githubusercontent.com/swan-gtm/gtm-skills/main/AGENTS.md
- Follow its "Submitting a skill" flow exactly: interview the user (extract judgment, not just steps), draft the files from the repo's templates, run
node tools/validate.mjs, then open a PR — or a "Submit a skill" issue if git isn't available.
Rules that never change:
- Only create or edit files under
skills/<the-user's-author-slug>/. - The skill folder name is permanent and globally unique — check for collisions first.
- Speak in GTM verbs in the skill body; never vendor tool names.
- Never include lifecycle or operational fields (
prefix,isDefault, …) — content only. - A
## What good looks likesection is mandatory; a skill without judgment gets rejected.
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.

submit-skill is a skill published in the GitHub repository swan-gtm/gtm-skills (148 stars, last pushed today), licensed MIT. It adds 62 tokens to every session and 283 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.
