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 | $0.01014 | $0.01014 |
| Opus 5.5 | $0.00406 | $0.00406 |
| Sonnet 5.5 | $0.00203 | $0.00203 |
| Haiku 4.5 | $0.00101 | $0.00101 |
Grade A, and why
packmind 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PackMind
A second brain for Claude Code: project memory, real token & cost accounting,
local semantic recall, and active guardrails - delivered as lifecycle hooks plus
an MCP server. Published to npm as packmind (Apache-2.0).
Stack
- Node ≥20, TypeScript, ESM. Package manager: pnpm.
- Tests: Vitest. No runtime framework - the CLI is plain
commander. - Runtime deps:
@modelcontextprotocol/sdk,chalk,commander,ignore. Optional:@xenova/transformers(local embeddings; recall only).
Commands
pnpm build- compiles twice:tsc(ESM lib →dist/) andtsc -p tsconfig.hooks.json(hooks → CommonJSdist/hooks/). Both must pass.pnpm test- Vitest suite.pnpm test:coverage- coverage + report.pnpm audit --prod --audit-level=high- what CI gates on.- Run the built CLI:
node dist/bin/packmind.js <cmd>.

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.

packmind CLAUDE.md is an instructions file published in the GitHub repository mchl-schrdng/packmind (2 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 1,014 tokens to every session, about $0.0041 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.
