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 | $0.00339 | $0.00339 |
| Opus 5.5 | $0.00136 | $0.00136 |
| Sonnet 5.5 | $0.00068 | $0.00068 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
sdd-skills 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 16d 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
sdd-skills
A public package of Claude Code skills for spec-driven development. The skills live in
skills/<name>/; docs/ holds the guide and the rationale and is not installed with them.
Before creating or changing a skill
Read docs/ARQUITETURA_DAS_SKILLS.md. It is the single source for how the skills call each
other, the signals and files they exchange, where each shared definition lives, which files read
which, and what to touch for each kind of change. Do not re-derive that from the SKILL.md
files.
- A
SKILL.mdis what runs. When it and the architecture doc disagree, the doc is wrong: fix it. - Update the architecture doc in the same commit as the change it describes.
- Work in progress and its status:
docs/PLANO_TESTES_MULTILINGUAGEM.md.
Rules of this repository
- Skills are generic. No path, runner, mocking rule, data policy or name of a particular project
goes into a skill; project facts are read from the project's
GATES.md. SKILL.mdandreferences/are written in English;docs/in Portuguese.- A concept more than one skill uses has one home; the others point to it.
- A skill is validated by running it in a fresh context, one subagent at a time, with each result saved to disk before the next starts.
coupling-mapis the only skill with executable code:node --test "skills/**/test/*.test.mjs".
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.

sdd-skills CLAUDE.md is an instructions file published in the GitHub repository dayvisonassis/sdd-skills (3 stars, last pushed 17d ago), licensed MIT.
