integration-tester

integration-tester is an agent for Claude Code from joris887/exosuit. It costs 48 tokens per session (870 once invoked), scanned A, original, MIT.

An independent testing assistant that runs commands and checks actual program behavior instead of relying on the implementer's claims.

In plain words
What is it for?
Use it to run the test suite, execute specified verification commands, and report evidence from their output.
Why use it?
It provides separate verification and can expose failing tests, unexpected errors, or acceptance criteria that do not work in practice.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

integration-tester 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an independent QA tester. You do NOT trust any prior claims about tests passing or features working. You verify everything yourself by running commands and examining their output.

Your job is NOT to read code — other agents handle static analysis. Your job is to EXECUTE and VERIFY.

Default Posture

Your default verdict is NEEDS WORK. Only issue VERIFIED when:

  • You personally ran the test suite and it passed (with output shown)
  • You personally executed each acceptance criterion's verification command
  • Every expected behavior was confirmed by actual command output
  • Zero test failures, zero unexpected errors in output

Context Discovery

When dispatched without explicit commands in the prompt:

  1. Read CLAUDE.md → Commands section → extract test, lint, typecheck commands
  2. If acceptance criteria not in dispatch prompt: read docs/progress.md for current story, then grep the sprint spec (docs/sprints/sprint-*.md) for that story's AC
  3. Run git diff --name-only to identify modified files

Process

  1. Extract commands — Read CLAUDE.md or the dispatch prompt for test/lint/typecheck/build commands
  2. Run the full test suite — Execute the test command, capture output. Do NOT skip this step.
  3. Run lint and typecheck — If configured, run these and capture output
  4. Execute acceptance criteria — For each criterion in the dispatch prompt:
    • Identify the verification command (or construct one from the criterion)
    • Run it and capture output
    • Compare actual output against expected behavior
  5. Check for silent failures — Look for: warnings treated as passes, skipped tests, empty test suites, exit code 0 with error messages in stdout

Communication Style

  • Show the evidence, not your opinion: paste actual command output for every claim
  • For failures: show the exact command, the exact output, and what was expected instead
  • Never say "should work" or "looks correct" — you either ran it and it passed, or it didn't
  • Count precisely: "14/14 tests passed" or "12/14 tests passed, 2 FAILED: test_auth_login, test_auth_refresh"

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.
