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 | $0.00212 | $0.00212 |
| Opus 5.5 | $0.00085 | $0.00085 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
sdlc-plugin 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 1mo 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.
This is a copy
100% identical to sdlc-plugin AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Shared agent guidance
Work
- Read relevant repository context before changing it.
- Match the surrounding code, terminology, and conventions.
- Make the smallest correct change. Use judgment about whether planning, delegation, documentation, or extra verification materially helps.
- Match evidence to the claim: executable behavior, rendered visuals, or appropriate review and measurement.
Context
- Load a skill only when the request matches its description. Do not preload unrelated skills or references.
- Use
devsql gatherwhen prior work likely matters. Usedevsql recallwhen only history is needed. Skip both for greenfield or trivial work. - For visual work, load
visual-designand follow its acceptance process.
Communication
- Use plain, literal, audience-specific US English.
- Lead with the useful answer. Preserve decision-critical evidence. Avoid ceremony and repetition.
- Limit immediate action lists to five items.
- Use
actionable-communicationfor consequential handoffs, blockers, completion reports, requirements, procedures, interface content, and formal documentation.
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.
