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 | $0.00578 | $0.00578 |
| Opus 5.5 | $0.00231 | $0.00231 |
| Sonnet 5.5 | $0.00116 | $0.00116 |
| Haiku 4.5 | $0.00058 | $0.00058 |
Grade A, and why
copilot workflows-and-customization.instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 24 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Workflows, hooks, and customizations instructions
GitHub Actions workflows (.github/workflows/**)
- Pin actions by SHA: Pin every third-party action to a full 40-character commit SHA with a
# ratchet:<action>@<version>comment. - Least-privilege permissions: Declare
permissions: contents: readat the workflow level and grant write permissions (contents: write,pull-requests: write,issues: write,id-token: write) only on the specific jobs that need them. - No untrusted interpolation in
run:: Never interpolate${{ github.event.* }}, branch names, PR titles/bodies, or step outputs containing external text directly insiderun:scripts. Pass values throughenv:variables and quote them in shell. - Safe
$GITHUB_OUTPUTwrites: When writing multiline values to$GITHUB_OUTPUT, generate a random heredoc delimiter withEOF_$(openssl rand -hex 8). - Supply-chain checks: Verify SHA-256 checksums (
sha256sum -c -) before extracting downloaded release archives in CI, and pin globalnpm install -gpackages to exact versions with--ignore-scripts.
Pre-tool hooks (hooks/** and .github/hooks/**)
- Mirror invariant: Every change to
hooks/*.pymust be copied byte-for-byte to.github/hooks/*.py. Runmise run hooks:test(python3 hooks/<name>.py --selftestanddiff -q) before committing. - Bypass resistance: When editing
ask-first-aria.py,klarsprak-gate.py, orgh-poll-gate.py, normalize file paths (posixpath.normpath), account for global CLI flags (git -C,gh -R/--repo), and add regression cases toSELFTESTS.
Customizations and documentation (agents/**, skills/**, instructions/**, prompts/**, docs/**)
- Language split: Write body text in
agents/,skills/,instructions/, andprompts/in English. Keep YAML frontmatterdescriptionandmetadata.jsonfields in Norwegian. Runmise run skills:lintandmise run generateafter changes. - Norwegian prose (
docs/**): Write clear Norwegian (klarspråk) without AI filler, em dashes, or unadapted English calques. Keep commands, flags, file paths, and code identifiers exact.
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.
