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 | $0.00426 | $0.00426 |
| Opus 5.5 | $0.00170 | $0.00170 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
markdy-com 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 2mo 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
Copilot instructions for this repository
- When the user says
ship it,release it, or gives shorthand likecommit, PR, merge, release, tag it, interpret that as a request to run the full shipping workflow for the current completed changes. - The default shipping workflow for this repo is:
- validate the current change with the full CI suite:
pnpm run ci(runs unit tests, AST backward compatibility gates, documentation examples, and Chrome DevTools headless E2E verification) - commit the finished product changes with a repo-style commit message
- open a PR and wait for checks
- merge the PR once checks pass
- cut the next patch release with
pnpm run release <next-version> - ensure
CHANGELOG.mdcontains concrete release notes before the release commit is created - push the version tag and confirm the GitHub Release workflow succeeds
- validate the current change with the full CI suite:
- Prefer the existing release automation in scripts/release.sh instead of manually stitching together a release flow.
- All 8 packages are dual-published:
- npmjs.com: Distributed under
@markdy/*(e.g.@markdy/core,@markdy/renderer-dom,@markdy/mcp-server) - GitHub Packages: Distributed under
@hoangyell/*onhttps://npm.pkg.github.comviascripts/publish-packages.mjs
- npmjs.com: Distributed under
- CI runs 4 parallelized jobs (
quality,testmatrix across Node 20 & 22,devtools-e2e, andwebsite). Thequalityjob runspnpm run buildprior topnpm run typecheckto ensure emitted declarations are available for cross-package workspace imports. - Keep the homepage example picker curated. Favor the strongest showcase scenes and avoid cluttering the homepage with weak, repetitive, or overly diagnostic examples.
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.
