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 | $0.00743 | $0.00743 |
| Opus 5.5 | $0.00297 | $0.00297 |
| Sonnet 5.5 | $0.00149 | $0.00149 |
| Haiku 4.5 | $0.00074 | $0.00074 |
Grade A, and why
snap 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 12d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Snap -- Project Context for Claude Code
What this is
A two-component system: a Tauri 2.x desktop app (Rust + vanilla JS) for screen annotation, and a Python MCP server that exposes the annotation inbox to coding agents.
Architecture
app/-- Tauri 2.x project. Vanilla HTML/CSS/JS frontend, no framework. Rust backend handles screen capture, window context, and file I/O.mcp-server/-- Python package usingfastmcp. Stdio transport. Reads from~/.snap/inbox/.
Key decisions
- Vanilla JS for the overlay frontend. No React, no build tooling beyond what Tauri provides.
- Screen capture on Wayland goes through the XDG desktop portal first (
org.freedesktop.portal.Screenshotover D-Bus viagio). GNOME 50 stopped lettinggnome-screenshotcapture, so the portal is the only silent route there. Fallbacks run as subprocesses with a 10s timeout:gnome-screenshot(older GNOME),grim(wlroots),scrot(X11). Tries each in order, uses the first that works. - Window context uses
xdotoolon X11. Returns None on Wayland. - Annotations stored as PNG + sidecar JSON pairs in
~/.snap/inbox/. - MCP server is read-only. It never writes annotations, only reads and deletes.
- On Wayland: app runs in single-shot overlay mode, triggered by GNOME custom keybinding via
snap-trigger.sh. - On X11: app runs as a persistent tray app with built-in global hotkey via Tauri's global-shortcut plugin.
Conventions
- Tauri commands use snake_case
- JS annotation objects match the sidecar JSON schema
- All file paths use
~/.snap/as the root - Error handling: never crash silently, always log to
~/.snap/snap.log - Log rotation at 1MB for both Rust and Python
- Git commits: short, direct messages
Build
make build # Build everything
make dev # Run in dev mode
npx tauri build # Rebuild Tauri app only (must use this, not cargo build alone)
Test
node --test app/src/export-scale.test.mjs
cd mcp-server && .venv/bin/python -m unittest discover -s tests
pwsh -File tests/install-windows.ps1 # install.ps1 config merging (needs PowerShell 7+)
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.

snap CLAUDE.md is an instructions file published in the GitHub repository adjective-rob/snap (11 stars, last pushed 12d ago), licensed MIT. It adds 743 tokens to every session, about $0.0030 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.
