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 | $0.20569 | $0.20569 |
| Opus 5 | $0.10285 | $0.10285 |
| Sonnet 5 | $0.04114 | $0.04114 |
| Haiku 4.5 | $0.02057 | $0.02057 |
Grade C, and why
memex CLAUDE.md scanned grade C with 3 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 6d 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **A request that carries embeddings must be batched by serialized size, never by a fixed item count.** `memex sync push`/`reconcile` batched conversations 500-at-a-time, bounded only by the server's `_MAX_SYNC_UUIDS` c Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

CLAUDE.md
Context and rules for any Claude Code instance working in this repo (including parallel worktrees).
Project idea in one line
The context Claude.ai has should also be available to Claude Code. Everything else (storage, embeddings, MCP, capture) is plumbing to get there.
Full detail in README.md and ROADMAP.md.
Working rules (apply ALWAYS)
- Read the code before and after editing. Before so you do not break anything, after to verify what ended up there.
- Keep README, ROADMAP, and DEVLOG in sync with every relevant change. Update them in the same iteration as the code.
- Review the code you just wrote for bugs before closing the task.
- When closing each ROADMAP phase, audit the whole project for bugs, obsolete code, and vulnerabilities. Deliver a written report.
- Plan before coding. No writing code without a clear plan.
- If there are real doubts, ask. Do not assume.
- Code and plans designed to scale. Clear separation of responsibilities (pure core, swappable transport, embedder and storage behind interfaces).
- No em dashes as connectors. Use commas, periods, parentheses. Applies to docs, commits, code, and replies to the user.
- No Claude shoutouts in commits. No
Co-Authored-By, no AI footers. Commits signed only by the human author. - Apply these rules in every iteration.
Stack
- Python 3.12+, package manager uv.
- FastMCP for the MCP server (supports stdio and SSE/HTTP).
- SQLite + sqlite-vec for storage and vector search.

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.

memex CLAUDE.md is an instructions file published in the GitHub repository dioniipereyraa/memex (6 stars, last pushed 1mo ago), licensed MIT. It adds 20,569 tokens to every session, about $0.1028 per session on Opus 5. A static security scan graded it C with 3 findings (downloads and executes remote code, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
