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 | $0.01563 | $0.01563 |
| Opus 5.5 | $0.00625 | $0.00625 |
| Sonnet 5.5 | $0.00313 | $0.00313 |
| Haiku 4.5 | $0.00156 | $0.00156 |
Grade B, and why
claude CLAUDE.md scanned grade B with 1 finding 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 10d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
Run a native `claude plugin eval` suite through `bun evals/native/run.ts <suite> -- <args>`, not the bare command. It strips `ANTHROPIC_API_KEY` so runs spend subscription credits, and stages the artifacts at `--ref` aga How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Plugin Marketplace
This repository contains my personal Claude Code configuration and a plugin marketplace (bendrucker) that allows others to install portions of my setup.
Structure
schemas/: JSON Schemas for Claude Code config formats. Upstream-backed ones (plugin,marketplace,settings) keep only our edits as an RFC 6902 overlay inschemas/overlays/, merged with the live upstream base in memory at validation time; the rest are hand-authoreduser/: User-level configuration, symlinked to~/.claudeby the claude topic in dotfiles.user/settings.jsonis the user settings for local machinesmanaged/settings.json: Settings for every platform, installed as a managed-settings drop-in, so they outrank project settingsplatforms/local/,platforms/remote/: Entries dotfiles links into~/.claudebesideuser/'s on a local machine or in a remote (cloud) session, replacing any of the same name:platform.md, whichuser/CLAUDE.mdimports, and the remotesettings.jsondocs/: Reference material too long to auto-inject, linked from the rule that needs it
Curation
Detectors of model behavior need particular care: models drift and rules lose value, so pair detection with a path to evolve or retire.
An invoked skill's body is re-injected in full at every compaction, so SKILL.md size is a recurring per-compaction cost rather than a one-time load. Author bodies under roughly 4k tokens and keep the detail in references/.
When the harness changes a default, assume the change encodes usage data you do not have and accommodate it. Push back only as a light-touch experiment with evaluation criteria and a removal trigger. Example: Claude Code v2.1.198 made Explore inherit the conversation model (capped at Opus) instead of Haiku, so Explore steering stays a soft default and is removed if inert after a couple of weeks.
Observability
Tooling here must be observable on my machines. Ship each mod, hook, or script with telemetry Claude can query and something that reads it. A mod emits through mod-events, which the session index reads into mod_events for its mods query (mods.md). A visibility gap outranks any new feature, so see before acting.
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.

claude CLAUDE.md is an instructions file published in the GitHub repository bendrucker/claude (18 stars, last pushed today), licensed MIT. It adds 1,563 tokens to every session, about $0.0063 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
