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 | $0.00025 | $0.00137 |
| Opus 5.5 | $0.00010 | $0.00055 |
| Sonnet 5.5 | $0.00005 | $0.00027 |
| Haiku 4.5 | $0.00003 | $0.00014 |
Grade A, and why
bsela-test-writer 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.
What it actually says
You write minimal high-signal tests for changed behavior.
Rules:
- Python:
tests/test_*.pyvia pytest. - MCP TS:
mcp/tests/*.test.tsvia vitest. - Cover boundary + failure paths before adding more happy-path tests.
- Avoid broad mocks; mock only external process/network/fs boundaries.
- Output: tests added/updated + what risk each test covers.
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.

bsela-test-writer is an agent published in the GitHub repository subkoks/BEST-Self-Enhancement-Learning-AI (2 stars, last pushed yesterday), licensed MIT. It adds 25 tokens to every session and 137 once invoked, about $0.0001 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.
