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 | $0.01059 | $0.01059 |
| Opus 5.5 | $0.00424 | $0.00424 |
| Sonnet 5.5 | $0.00212 | $0.00212 |
| Haiku 4.5 | $0.00106 | $0.00106 |
Grade A, and why
ccx-context-system 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 2mo 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 — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this is
A Claude Code plugin marketplace repo whose single plugin, ccx (plugins/ccx/), provides scratch-notebook context management for any project: per-thread STATE.md handoff docs under .scratch/<thread>/, plus a compiled INDEX.md dashboard. Everything (scripts, hooks, tests) runs under bun, regardless of the host project's language.
Commands
- Tests:
bun tests/run-tests.ts— single-file scenario harness (no test framework;ok()assertions, exits non-zero on failure). It builds fresh fixture projects in a tmpdir each run (a fake Go project on stock config + a custom-config project) and exercises every script and the backlink hook. There is no per-test runner; run the whole file. - Validate plugin structure:
claude plugin validate ./plugins/ccx(andclaude plugin validate .for the marketplace). - Try changes live in one session:
claude --plugin-dir ./plugins/ccx. - Refresh an installed copy after edits:
/plugin marketplace update ccx-context-system(or restart the session).
Architecture
Three layers, all under plugins/ccx/:
- Skills (
skills/*/SKILL.md) —start-thread,save-state,tidy-scratch. Markdown with frontmatter; they inject live data at load time via!`bun "${CLAUDE_PLUGIN_ROOT}/scripts/<x>.ts"`preamble commands, then instruct the model. Skills never re-implement logic that scripts own (e.g. slugging goes throughslug.ts). - Scripts (
scripts/*.ts) — deterministic bun CLIs the skills call:where.ts(resolved context),threads.ts/orphans.ts/scan.ts(read-only scans),slug.ts,compile-index.ts(the INDEX compiler). - Hooks (
hooks/hooks.json→ scripts) — four:backlink-scratch-notes.ts(PostToolUse on Write: prepends a[[STATE]]wikilink to new unlinked scratch notes);auto-compile-index.ts(PostToolUse on Write|Edit: a STATE-doc write kicks a detached,.pending-debounced INDEX recompile — the INDEX saves itself);record-session-thread.ts(UserPromptExpansion onstart-thread: records{display, slug, source, ts}to<scratch_root>/.sessions/<session_id>.json);state-freshness-guard.ts(Stop: work newer than the associated thread's STATE → block the stop once with "persist Status/summary first"; GRACE 10 min · THROTTLE 30 min ·stop_hook_active-safe ·SKIP_STATE_GUARD=1escape). Hooks read the tool-call JSON from stdin and fail open — any parse error or unexpected input →exit 0; a hook must never crash the session — and stay silent on the pass path.
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.

ccx-context-system CLAUDE.md is an instructions file published in the GitHub repository shck-dev/ccx-context-system (1 stars, last pushed 3mo ago), licensed MIT. It adds 1,059 tokens to every session, about $0.0042 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.
