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 | $0.00634 | $0.00634 |
| Opus 5 | $0.00317 | $0.00317 |
| Sonnet 5 | $0.00127 | $0.00127 |
| Haiku 4.5 | $0.00063 | $0.00063 |
Grade A, and why
fusion-skills copilot-instructions.md 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 5d 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.

Copilot Instructions
Repository-wide guidance for Copilot in this repository.
Scope
- Keep this file under 100 lines and applicable to all repository contexts.
- Put detailed, domain-specific rules in
.github/instructions/*.instructions.md.

Skill discovery defaults
- For local skill discovery in this repository, search
skills/first. - Include
skills/andskills/.experimental/in local.agents/skillslookup paths for this workspace.
SKILL.md size limits
- SKILL.md files must stay under 500 lines (CI error threshold).
- SKILL.md files above 300 lines trigger a CI warning — consider moving content to
references/. - See
contribute/02-skill-structure-and-content.mdfor the cross-platform size rationale and progressive disclosure guidance.
SKILL.md prose style
Write skill prose for minimal token cost. Every token in SKILL.md is loaded into context on activation.
- Drop articles (a/an/the), filler (just/really/basically/simply), and hedging
- Use fragments: "Run tests before commit" not "You should always run tests before committing"
- Short synonyms: "fix" not "implement a solution for", "use" not "utilize"
- State actions directly — drop "you should", "remember to", "make sure to"
- Merge redundant bullets; keep one example when multiple show the same pattern
- In SKILL.md files, never modify code blocks, inline code, paths, URLs, or technical terms
- To compress any
skills/**/*.mdfile, use thecaveman-compressskill (.agents/skills/caveman-compress):/caveman:compress skills/<name>/SKILL.md
Maintainer docs
- For maintainer workflow and policy context, use
contribute/README.mdand the topic files incontribute/.
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.

fusion-skills copilot-instructions.md is an instructions file published in the GitHub repository equinor/fusion-skills (1 stars, last pushed 4d ago), licensed MIT.
