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 | $0.00013 | $0.00068 |
| Sonnet 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 11d 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 3d ago), licensed MIT. It adds 25 tokens to every session and 137 once invoked, about $0.0001 per session on Opus 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.
Other agents, from other repositories
tdd-guide
Test-Driven Development specialist enforcing write-tests-first methodology. Use PROACTIVELY when writing new features, fixing bugs, or refactoring code. Ensures 80%+ test coverage.
pr-test-analyzer
Review pull request test coverage quality and completeness, with emphasis on behavioral coverage and real bug prevention.
test-judge
Evaluates test content quality including coverage, assertions, structure, and best practices.
test-engineer
Specialized in Python testing with pytest. Expert in running tests, fixing failures, and ensuring test coverage. Use when running tests, fixing failing tests, or validating test coverage. Does NOT write new tests - focuses on running and fixing.
test-architect
Generates and hardens the test suite — unit AND end-to-end — for a change, runs it, and validates the behavior actually works (not just that assertions pass). Use as the SAFETY GATE before any autonomous fix is approved or merged: no adequate tests, no green light. The thing that makes the autonomous loops safe.
test-writer
Behavioral test generation subagent.
