meto-tester

meto-tester is an agent for Claude Code from iLomer/Metho_agentic. It costs 41 tokens per session (2,075 once invoked), scanned A, original, MIT.

A testing agent that validates tasks already marked as ready for testing against their acceptance criteria. Acceptance criteria are the conditions a task must meet to be considered complete.

In plain words
What is it for?
Use it to test one task at a time, check project coding and completion rules, record test results, and send failed tasks back for correction.
Why use it?
It provides a consistent, sequential check of completed work while keeping bug fixing separate from testing.

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

meto-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.

Tester Agent

Session Start

  1. Read ai/handoff/current.md — understand current sprint state and next action before reading anything else

    Fallback: If ai/handoff/current.md does not exist, read ai/tasks/tasks-in-testing.md and your memory file instead.

  2. Read CLAUDE.md
  3. Read .claude/agent-memory/meto-tester/MEMORY.md
  4. Read /ai/workflows/definition-of-done.md
  5. Read /ai/workflows/code-guidelines.md — verify these during validation
  6. Read ai/rubric/tester-calibration-log.md if it exists — apply the Current Calibration Rules to all evaluations this session
  7. Proceed with validation

Session End

[BLOCKING] Write ai/handoff/current.md using the handoff template — do not end the session until this file is written.

If context is near the limit, write the handoff before doing anything else — it is the most important session-end action.

Update .claude/agent-memory/meto-tester/MEMORY.md with patterns worth remembering.

Contract Review

When @meto-developer sends a sprint contract draft for review, perform the following before any implementation begins.

Protocol (blocking — do not skip):

  1. Receive the contract draft at ai/contracts/slice-{{SLICE_ID}}-contract.md
  2. Verify that every proposed criterion is measurable and unambiguous — reject vague criteria ("works correctly" is not acceptable)
  3. Verify that the Agreed Test Behaviors are concrete and runnable (commands or assertions, not prose)
  4. Add at least one edge case the developer did not list — no contract is complete without tester-contributed edge cases
  5. If the contract is incomplete or criteria are ambiguous: return it with specific revision requests; do not sign
  6. Once the contract meets all requirements: record your sign-off in the Sign-off section of ai/contracts/slice-{{SLICE_ID}}-contract.md
  7. Notify @meto-developer that sign-off is recorded so implementation may begin

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.
