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 | $0.01104 | $0.01104 |
| Opus 5.5 | $0.00442 | $0.00442 |
| Sonnet 5.5 | $0.00221 | $0.00221 |
| Haiku 4.5 | $0.00110 | $0.00110 |
Grade A, and why
second-brain-starter-kit AGENTS.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 1mo 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — working in this repo
Written for AI coding agents, and equally readable by a human contributor. Short on purpose. Русская сводка — в конце.
What this repo is
A working "Claude Code as a second brain + working assistant" setup, stripped of personal data and cut down to a portable core: the method, not the data. 100 skills, a CRM engine with sample data, vault templates, engine passports, and the seed message that starts the first session.
The primary reader is someone else's agent, bootstrapping a system for its own operator. That shapes everything below: instructions must survive being executed by a model that has never seen this repo, on a machine you know nothing about.
Layout
SEED.md— the first message a user pastes into Claude Code. Everything starts here.BOOTSTRAP-CLAUDE.md— instructions to the installing agent.CLAUDE-EXTERNAL.md— the working principles that become the user's ownCLAUDE.md.skills/— 100 skill commands, mapped inskills/INDEX.md.crm-template/— markdown "card = file" CRM plus the scoring engine and demo data.engines/— the published engines;engines/PASSPORTS.mdis their catalogue.templates/,docs/— note templates, onboarding, and what is/isn't shared.HANDOVER.md— entry point if the reader already runs a fleet of agents.
How to verify a change
The one command that exercises real logic end to end, offline:
cd crm-template/reference
python demo.py # scores the shipped sample, prints bands, queue, and an agreement check
Read what it prints before you "fix" it: the priority column is expected not to reproduce exactly, because the export deliberately does not carry three signals that live in the message store. That gap is documented, not a bug — a PR that makes the numbers agree by changing the model is going the wrong way.
If you changed a skill or a doc, verification is different: paste the before/after of the concrete
file, per docs/HOW-TO-CONTRIBUTE.md. Abstract "this could be improved" is nearly impossible to
judge and will come back as a question.
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.

second-brain-starter-kit AGENTS.md is an instructions file published in the GitHub repository tonydzi/second-brain-starter-kit (9 stars, last pushed today), licensed MIT. It adds 1,104 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.
