career-ops-ui: Agent for Claude Code

.claude/agents/test-isolation-reviewer.md

test-isolation-reviewer is an agent for Claude Code from Fighter90/career-ops-ui. It costs 49 tokens per session (489 once invoked), scanned A, original, MIT.

A review agent for checking whether tests in the career-ops-ui project can run safely in continuous integration (CI), the automated environment that tests code.

In plain words
What is it for?
Use it after changing files in tests/ to check isolation, temporary-file use, subprocess cleanup, network access, and deterministic assertions.
Why use it?
It catches tests that depend on files, network services, fixed ports, timing, or processes outside their test environment.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is Fighter90/career-ops-ui's own configuration. It tells Claude Code how to work on career-ops-ui itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything career-ops-ui configures →

Token cost

What it costs to keep this loaded

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.

Security

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, or modes/* exist outside the test sandbox.
  • If the test exercises paths.mjs / PATHS.*, it must set CAREER_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(). Use child.kill('SIGTERM') then a watchdog setTimeout that escalates to SIGKILL.

4. Filesystem isolation

  • Writes go to a tmp dir, never to data/, reports/, output/, or jds/.
  • mkdtemp / mkdtempSync is the right primitive. Clean up in after().

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.

Changes

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.
