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 | $0.00049 | $0.00489 |
| Opus 5 | $0.00024 | $0.00244 |
| Sonnet 5 | $0.00010 | $0.00098 |
| Haiku 4.5 | $0.00005 | $0.00049 |
Grade A, and why
test-isolation-reviewer 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 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.
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 audit career-ops-ui tests for CI safety. CI clones only web-ui/ — the parent career-ops project is NOT present.
Checks
1. Parent isolation
- Tests must NOT assume
cv.md,data/applications.md,portals.yml,config/profile.yml, ormodes/*exist outside the test sandbox. - If the test exercises
paths.mjs/PATHS.*, it must setCAREER_OPS_ROOT=<mktemp -d>and write the minimum files needed.
2. Network isolation
- No live HTTP outside the test process. SSE / fetch tests hit the in-process
createApp()on an ephemeral port (server.listen(0)). - Never test against
4317(the dev port) — collisions break parallel runs.
3. Subprocess hygiene
- Spawned processes must be killed in
after()/afterEach(). Usechild.kill('SIGTERM')then a watchdogsetTimeoutthat escalates toSIGKILL.
4. Filesystem isolation
- Writes go to a tmp dir, never to
data/,reports/,output/, orjds/. mkdtemp/mkdtempSyncis the right primitive. Clean up inafter().
5. Determinism
- No
Date.now()-dependent assertions without freezing the clock or asserting a range. - No reliance on file order — always
sort()directory listings. - No reliance on the parent project being on the same Node minor version as CI.
6. Coverage discipline
- Don't write tests against private internals if a public API path exists.
createApp()is the public surface. - Aim for branch coverage on conditionals — happy path AND the error path.
How to report
Same format as web-ui-route-reviewer. If clean: LGTM — test is CI-safe.
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-isolation-reviewer is an agent published in the GitHub repository Fighter90/career-ops-ui (62 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 489 once invoked, about $0.0002 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 2026-08-30.
Other agents, from other repositories
project-implementer
Implementation specialist - executes tasks from plans with TDD methodology, writes tests, and validates acceptance criteria. Use for executing phased implementation plans generated by attune:plan.
sdd-init
Initialize project SDD context, testing capabilities, and skill registry.
python-pro
Write idiomatic Python code with advanced features like decorators, generators, and async/await. Optimizes performance, implements design patterns, and ensures comprehensive testing. Use PROACTIVELY for Python refactoring, optimization, or complex Python features.
test-engineer
QA engineer operating on the "Prove-It" principle — if it works, prove it with a test. Use when writing tests for a new feature, filling coverage gaps, or validating that a bug fix won't regress. Can read, write and edit test files. Dispatch with Task tool for isolated test work.
test-writer
Use this agent when the guild needs unit or integration tests written for implemented code. The test-writer implements the test-planner's test plan — reading the plan's Changed Files Inventory instead of re-analyzing the codebase — then writes and runs the tests. Spawned by the check-in skill when a test-writing task…
