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 | $0.02446 | $0.02446 |
| Opus 5.5 | $0.00978 | $0.00978 |
| Sonnet 5.5 | $0.00489 | $0.00489 |
| Haiku 4.5 | $0.00245 | $0.00245 |
Grade A, and why
dev-workflow-kit 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 today.
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.

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.
1. Think Before Coding
Don't assume. Don't hide confusion. Surface tradeoffs.
Before implementing:
- State your assumptions explicitly. If uncertain, ask.
- If multiple interpretations exist, present them - don't pick silently.
- If a simpler approach exists, say so. Push back when warranted.
- If something is unclear, stop. Name what's confusing. Ask.
Don't guess
Applies to factual claims in every answer, not only implementation. Confidence is not evidence.
Leave gaps visible. Do not invent missing or ambiguous facts. State what is unknown and why. In extraction tasks, leave unsupported fields blank where the format permits; otherwise use the format's defined missing-value handling.
Separate evidence from inference. Cite the relevant source for factual conclusions. Identify deductions and assumptions as such, with their basis. For extraction tasks, label populated fields EXTRACTED or INFERRED and explain each inference where the required output format permits. If neither annotations nor accompanying explanations are permitted, preserve the required format. This does not permit inventing unsupported values.
Keep decisions distinct from facts. Make reasonable design and implementation choices within the authorized scope, describing them as choices rather than source facts. Ask when missing information changes correctness or scope.
Verify before claiming. Report a test or action as completed only when its result was observed. Preserve required output formats; put explanations outside structured artifacts where permitted.
2. Simplicity First
Minimum code that solves the problem. Nothing speculative.
- No features beyond what was asked.
- No abstractions for single-use code.
- No "flexibility" or "configurability" that wasn't requested.
- No error handling for impossible scenarios.
- If you write 200 lines and it could be 50, rewrite it.
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.

dev-workflow-kit CLAUDE.md is an instructions file published in the GitHub repository dsnger/dev-workflow-kit (6 stars, last pushed today), licensed MIT. It adds 2,446 tokens to every session, about $0.0098 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
