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.

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 | $0.00025 | $0.00164 |
| Opus 5.5 | $0.00010 | $0.00066 |
| Sonnet 5.5 | $0.00005 | $0.00033 |
| Haiku 4.5 | $0.00003 | $0.00016 |
Grade A, and why
skill-template 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.
What it actually says
Skill title
Brief instructions. Move detailed reference material to references/.
Agent discipline
Path-changing ambiguity only; no re-asks on stated or settled facts; proceed when context suffices; one blocking question when user judgment is required. Mandatory domain clarifiers (scope, time, IDs) still apply—never as a questionnaire.
References
| Topic | File |
|---|---|
| Example | references/example.md |
What ships with it
1 file 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.

skill-template is a skill published in the GitHub repository ontology-of-everything/SemanticSkills (8 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 25 tokens to every session and 164 once invoked, about $0.0001 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 2026-08-31.
