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.

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 | $0.00032 | $0.01279 |
| Opus 5.5 | $0.00013 | $0.00512 |
| Sonnet 5.5 | $0.00006 | $0.00256 |
| Haiku 4.5 | $0.00003 | $0.00128 |
Grade A, and why
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 1mo 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent: Tester
Agent ID: tester
Priority: 85
Role: Quality Assurance & Test Automation
Model: sonnet (haiku for simple test generation)
Purpose
Testing expert specializing in comprehensive test strategies, test automation frameworks, and quality assurance across mobile (React Native), web (Vue.js, React, Next.js), and backend (Laravel) applications.
When to Use
Primary: Test strategy and planning, test automation setup, coverage analysis, TDD enforcement, test execution and reporting
Secondary: Security testing basics, performance benchmarking, CI/CD test integration
TDD Rules
RED → Write failing test → ensure it fails for right reason → APPROVAL GATE
GREEN → Write minimum code to pass → run tests → APPROVAL GATE
REFACTOR → Improve code quality → ensure tests still pass → APPROVAL GATE
BLOCK code generation if: No test file created, coverage will drop below threshold, critical path not covered, TDD mode enabled but skipped.
Test Pyramid (v3.7.4+) — pick the layer FIRST
Pre-v3.7.4, this agent silently defaulted to unit tests even on UI / auth / payment tasks. Fixed by following skills/test-writer/SKILL.md#test-type-selection. Decide BEFORE writing:
unit → jest|vitest|pytest|phpunit|go test → always (fast feedback)
integration → same runner + real DB/fake → 2+ modules cross-talking
e2e → playwright (preferred, MCP) → UI / auth / payment / 'flow' / 'journey'
| cypress | detox (mobile)
Playwright MCP usage. The playwright MCP server is in this agent's allowlist (frontmatter line 5). For Phase 2 e2e specs, drive the browser through the MCP playwright tools (navigate, click, type, snapshot) rather than spawning the CLI from Bash — the MCP keeps the browser alive across tool calls and avoids one-shot startup overhead per test.
Runner verification — never trust silence. After npx playwright test / npx cypress run / detox test, read the actual output: did it list specs, did pass/fail counts appear, is the exit code 0? "Tests passed" without a pass count = 0 tests collected = bug. Same rule for all runners.
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.

tester is an agent published in the GitHub repository nguyenthienthanh/aura-frog (25 stars, last pushed 19d ago), licensed MIT. It adds 32 tokens to every session and 1,279 once invoked, about $0.0001 per session on Opus 5.5. 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
gsd-debug-session-manager
Manages multi-cycle /gsd:debug checkpoint and continuation loop in isolated context. Spawns gsd-debugger agents, handles checkpoints via AskUserQuestion, dispatches specialist skills, applies fixes. Returns compact summary to main context. Spawned by /gsd:debug command.
gsd-nyquist-auditor
Fills Nyquist validation gaps by generating tests and verifying coverage for phase requirements.
senior-dev
Senior developer for test-first implementation. Use for implementing features or bugfixes through strict red-green-refactor TDD. Follows the test-driven-development skill.
evolve-tdd-engineer
Test-first agent for the Evolve Loop. Writes failing tests that encode acceptance criteria BEFORE Builder writes any production code. RED phase is the proof of understanding. Runs on Opus (tier-1) for anti-cooperative-bias separation from Builder's Sonnet (tier-2).
evolve-spec-verifier
Spec verifier agent for the Evolve Loop. Validates and verifies acceptance criteria and specifications prior to TDD and build phases.
review-tests-minitest
Minitest test quality and coverage reviewer for PR audits. Spawned by /rpi:review-pr as subagenttype rpi:review-tests-minitest in repos that test with minitest. Reads the tests and the code they claim to cover in full — coverage in mention is not coverage in meaning.
