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 | $0.00000 | $0.00184 |
| Opus 5.5 | $0.00000 | $0.00074 |
| Sonnet 5.5 | $0.00000 | $0.00037 |
| Haiku 4.5 | $0.00000 | $0.00018 |
Grade A, and why
TEST-AND-LINT 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.
What it actually says
Fix and Failing Tests and Lint Errors
Overview
You are to run the tests of the frontend and backend with coverage enabled to ensure that both all tests are passing and the neccessary coverage is reached. You are also responsible for running the linter in both the frontend and backend to ensure that all linter errors have been handled accordingly
Steps
- Run the frontend tests with coverage and improve coverage where needed and fix any failing tests
- Run the frontend linter and fix any linting errors that appear
- Run the backend tests with coverage and improve coverage where needed and fix any failing tests
- Run the backend linter and fix any linting errors that appear
Important
This task is not complete until all 4 steps have been completed and all test are passing, linter errors are resolved, and coverage is above 80% across all packages.
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.

TEST-AND-LINT is a command published in the GitHub repository dep/agent-rules (11 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 184 tokens. 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 2026-08-30.
