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 | $0.01015 | $0.01015 |
| Opus 5.5 | $0.00406 | $0.00406 |
| Sonnet 5.5 | $0.00203 | $0.00203 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
yorkie-js-sdk CLAUDE.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 20d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yorkie JavaScript SDK
pnpm monorepo with multiple packages for building collaborative editing applications.
Development Commands
pnpm i # Install (pnpm enforced)
pnpm sdk build # Build core SDK
pnpm sdk build:proto # Regenerate protobuf code (buf generate)
pnpm lint # ESLint with auto-fix (zero warnings enforced)
# Tests require a running Yorkie server:
docker compose -f docker/docker-compose.yml up --build -d
pnpm sdk test # Run all SDK tests (waits for the server first)
pnpm sdk test test/integration/tree_test.ts # Specific test file
Package filters: pnpm sdk, pnpm react, pnpm schema, pnpm prosemirror, pnpm devtools
After Making Changes
Always run before submitting:
pnpm verify:fast # lint, licence headers, doc links, build, unit tests (~30s, no server)
pnpm sdk test # plus the integration suites, with the server above running
Task Workflow
- Plan — write
docs/tasks/active/YYYYMMDD-<slug>-todo.mdbefore code; updatedocs/design/if architecture changes. - Branch + commit — topic branch from
main; each commitpnpm verify:fastgreen.bash scripts/setup.shinstalls hooks that check this for you — lint-staged on commit,verify:faston push. - Self review —
/self-review: review → fix → re-verify over the full branch diff, max 3 rounds, stopping at the first round with no blocking findings. Log each round in*-lessons.md; a finding you believe is wrong goes there with evidence. - Open PR — rebase onto the base first (
origin/main, orupstream/mainfrom a fork). Body = Summary + Test plan. - Before merge —
bash scripts/tasks-archive.sh && bash scripts/tasks-index.sh, and turn anything left under "Out of scope" / "Open" in the todo into an issue.node scripts/tasks-check.mjs --base origin/main --remote(CI runs it on every PR) warns when a finished task is still inactive/.
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.
