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 | $0.01107 | $0.01107 |
| Opus 5.5 | $0.00443 | $0.00443 |
| Sonnet 5.5 | $0.00221 | $0.00221 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade A, and why
claudemd 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 13d 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AUTONOMY_LEVEL: aggressive
Solo OSS maintainer running with bypassPermissions. Atomic-ship convention applies (commit + push + tag + push tag + gh release create in one turn, except that the turn yields while the pre-tag reviewer runs, per §EXT §12 and runbook step 7) — see feedback_claudemd_ship_from_main_atomic.md. main is what users install (marketplace auto-update follows it on a version bump; /claudemd-refresh installs its HEAD), so a release is built and reviewed on release/vX.Y.Z with a draft PR and reaches main only together with its tag, and commits that change shipped files (hooks/, spec/, commands/, scripts/, bin/, .claude-plugin/) wait on the next-release branch, not on main. §5.1 Never-downgrade set binds as written in core §5.1.
Layout (core §2 Where files go defers to this): docs/ and tasks/ are gitignored; the tracked exceptions are listed in .gitignore (reference docs, tasks/specs/, evaluation and provenance files). A dated analysis under docs/ is committed with git add -f once shipped text or a tracked document cites it; working notes stay local.
claude-mem-lite — persistent memory
PreToolUse hooks already run mem_recall for past lessons before Read/Edit/Write. The calls worth making proactively:
| When | Call |
|---|---|
| Before Edit/Write | hook already recalled; if an injected #NN lesson changed what you did, add the bare tag (#NN) once at the end of the sentence describing that change (citing = adopting; uncited lessons decay; skip ones that did not apply). No other mention of memory ids, saves or the memory store in replies to the user |
| A recalled memory drives an answer or a design choice | check its claim in the code or git log first: #NN and E#NN rows are notes from past sessions, many written automatically, so they can be wrong, and they describe the code as it was. If the code disagrees, trust the code and replace the note: mem_save(..., supersedes=[NN]), or supersedes=["E#NN"] for an event |
| After fixing a non-trivial bug | mem_save(type="bugfix", lesson_learned="<root cause + fix, only what this change's diff shows>", importance=2) |
| After a non-obvious architecture decision | mem_save(type="decision", lesson_learned="<constraint + tradeoff>") |
| Deferring to a future session | `mem_defer({title, priority:1 |
| Looking up past work / history | mem_search "keywords" · mem_recent · mem_timeline |
Path cost is round-trips, not milliseconds: the PreToolUse hook above already recalls (0 calls) — prefer it. For an explicit query, if these mem_* tools are deferred behind ToolSearch this session, the Bash CLI claude-mem-lite is one call vs two (ToolSearch + call); the MCP server instructions carry the absolute path to use when it is not on PATH.
Full tool + CLI tables, citation/decay rules, and save discipline → .claude/plugin_claude_mem_lite.md
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.

claudemd CLAUDE.md is an instructions file published in the GitHub repository sdsrss/claudemd (3 stars, last pushed 6d ago), licensed MIT. It adds 1,107 tokens to every session, about $0.0044 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.
