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 | $0.02029 | $0.02029 |
| Opus 5.5 | $0.00812 | $0.00812 |
| Sonnet 5.5 | $0.00406 | $0.00406 |
| Haiku 4.5 | $0.00203 | $0.00203 |
Grade A, and why
blurt 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.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This repository's canonical agent instructions live in AGENTS.md — read that first.
It is tool-agnostic and covers the architecture, the settled decisions you must not reintroduce, the
conventions, and how to verify a change.
This file adds only what is specific to Claude Code: the tooling wired up under .claude/.
Hooks (.claude/settings.json)
| Hook | What it does |
|---|---|
SessionStart → session-start.sh |
Web/Linux sandboxes only (CLAUDE_CODE_REMOTE=true): installs the portable linters so scripts/check.sh --portable works, then prints a preflight noting CI is the authority on green. SwiftLint and swift-format are not installed — their Linux builds ship as GitHub release binaries, which the default network policy blocks. Local macOS sessions exit immediately. |
PreToolUse → protect-pbxproj.sh |
Blocks edits to App/Blurt/Blurt.xcodeproj/project.pbxproj (exit 2). Edit App/Blurt/project.yml and run xcodegen generate instead. (The iPhone project, App/BlurtiOS/BlurtiOS.xcodeproj, isn't committed at all: edit App/BlurtiOS/project.yml; every script regenerates it.) |
PostToolUse → swift-format.sh |
Formats every edited *.swift file with the repo's .swift-format config, so edits are CI-clean by construction. No-ops when the tool is absent. |
PostToolUse → swiftlint.sh |
Lints edited Swift files and surfaces violations immediately rather than at check.sh time. |
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.

blurt CLAUDE.md is an instructions file published in the GitHub repository AssemblyAI/blurt (65 stars, last pushed today), licensed MIT. It adds 2,029 tokens to every session, about $0.0081 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.
