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 | $0.01646 | $0.01646 |
| Opus 5.5 | $0.00658 | $0.00658 |
| Sonnet 5.5 | $0.00329 | $0.00329 |
| Haiku 4.5 | $0.00165 | $0.00165 |
Grade A, and why
addon-studio 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 22d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Instruções para agentes trabalhando neste repositório (o plugin em si).
Estas regras valem para o desenvolvimento do plugin. Elas não são as regras de projetos Sankhya Addon Studio consumidores — essas vivem em
plugins/addon-studio/skills/init/assets/ADDON.md.
O que é este repo
Marketplace Claude Code (snk-devcenter) + o plugin addon-studio (skills e sub-agents para projetos Sankhya Addon Studio 2.0).

Não há build do plugin: o entregável é markdown + JSON. O único empacotamento é scripts/build-release-artifacts.sh, que gera os instaladores e pacotes anexados à GitHub Release. Validação = ler o diff, conferir os manifests (jq . <arquivo>) e, se tocar nos instaladores, rodar sh scripts/test-release-artifacts.sh.
Mexeu em description de skill ou de sub-agent? Rode a esteira de disparo antes do PR — tools/skill-trigger-audit/README.md. Ela mede se a skill dispara sem âncora no projeto e guarda o histórico em runs/; description nova sem cenário na esteira passa a ser dívida.
Versionamento — regra principal
PR não mexe em versão. Quem abre PR não decide release. Nenhum PR de conteúdo pode alterar:
plugins/addon-studio/.claude-plugin/plugin.json→version.claude-plugin/marketplace.json→plugins[].version
Esses dois só mudam no commit de corte de release, junto da tag. (A badge do README.md é dinâmica — lê a última release pela API do shields.io, não precisa de bump.) Consequência prática: subject de commit e título de PR não carregam (vX.Y.Z) — o histórico antigo faz isso, é legado, não replicar.
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.
