Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01387 | $0.01387 |
| Opus 5 | $0.00694 | $0.00694 |
| Sonnet 5 | $0.00277 | $0.00277 |
| Haiku 4.5 | $0.00139 | $0.00139 |
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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 83 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. |
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.

scarf AGENTS.md
Instructions for awizemann/scarf: This repo carries its own agent memory — plain files in git, served by the in-repo memophant-mcp MCP server, managed by the Memophant macOS app. It works the same for every agent (Claude Code, Codex, Cursor, Gemini, Copilot). This block is regenerated between the memophant markers…

Instructions for awizemann/scarf: File memory notes under one of six folders (architecture/conventions/decisions/operations/project/roadmap), never the root. When a note is grounded in code, pass sourcepaths (the repo files it depends on) so Memory Health can drift-check it — an unanchored code note can't be kept…
