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 | $0.01118 | $0.01118 |
| Opus 5.5 | $0.00447 | $0.00447 |
| Sonnet 5.5 | $0.00224 | $0.00224 |
| Haiku 4.5 | $0.00112 | $0.00112 |
Grade A, and why
flowspec 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 yesterday.
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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — flowspec-cli
Project
Name: flowspec-cli
Repo: github.com/jpoley/flowspec
Purpose: CLI toolkit that initialises, upgrades, and orchestrates AI agent workflows using Spec-Driven Development (SDD). Ships as flowspec (and legacy alias specify).
Current focus: Run backlog task list -s "In Progress" --plain to see the active task
Operator Preferences
- State facts only. No sugarcoating.
- Surface problems, blockers, and risks immediately.
- Consult before one-way-door decisions and before any architectural change.
- Never answer from a guess. Validate claims against primary sources; if impossible, say so explicitly.
- Objective language. No first-person pronouns. No apologies or hedges.
Hard Guardrails (always apply)
- Plan before any non-trivial change. Write the plan to
.claude/plans/. Wait for approval. - Never commit or merge directly to
main. - Never commit secrets, tokens, keys, or
.envfiles. - No destructive git (
reset --hard, force-push, branch delete) without explicit operator approval. - NEVER delete test files or test methods without explicit human instruction — see
.claude/rules/critical.md. - NEVER edit
backlog/tasks/*.mdfiles directly — usebacklog task editCLI only. - All commits require DCO sign-off:
git commit -s -m "...". - Run formatter + linter + tests after every change set before declaring done.

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.

flowspec CLAUDE.md is an instructions file published in the GitHub repository jpoley/flowspec (50 stars, last pushed yesterday), licensed Apache-2.0. It adds 1,118 tokens to every session, about $0.0045 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 2026-10-09.
