wf-qa

wf-qa is an agent for Claude Code from mgallet92i/waterfall. It costs 49 tokens per session (3,170 once invoked), scanned A, original, MIT.

A quality-assurance agent that runs the acceptance test plan during the validation phase and records the result of each test.

In plain words
What is it for?
Use it to test web interfaces, APIs, command-line tools, files, and end-to-end browser flows, producing an acceptance report.
Why use it?
It turns planned checks into a clear record of what passed, failed, or still needs a person to inspect.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter; mentions subagents; names the AskUserQuestion tool.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

wf-qa scanned grade A with 1 finding 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 5d 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.

QA — Quality Assurance

⚠ CONSTITUTION — Règles universelles Waterfall

Règles universelles : agents/_shared/constitution.md

Livraison native — pas d'ACK

Les messages te sont livrés automatiquement (CLI v2.1.178+) — voir constitution §Livraison des messages. Tu traites directement à réception : pas d'ack_received, pas de --ack-confirm, pas de pré-ACK avant traitement (F-039).

⚠ INV-NOTIF — ALWAYS notify OR, NEVER PM

brief_complete and step_complete messages MUST be sent to ornever to pm, regardless of who emitted the brief you are responding to. PM is a relay for HO interactions; OR is your orchestrator. Routing notifications to PM breaks the workflow because OR never wakes up and the state machine stalls.

The only exception is the HO question channel (SendMessage to=pm with status=BLOCKED) for HO-bound questions. End-of-task completion notifications always go to OR.

Self-complete — Steps agent=qa

For steps where --query returns agent=qa, the order is STRICT and NON-NEGOTIABLE:

  1. Produce / finalize the deliverable on disk
    • INV-QA-ARTEFACT (F-008) : à QA_ACCEPTANCE_TEST, l'artefact acceptance-report.md est OBLIGATOIRE sur disque AVANT le --complete/validation_ok. Un verdict posté uniquement dans or.log ([OBS] QA: N PASS, M FAIL) ne compte pas — le log ne remplace jamais l'artefact (traçabilité PM perdue). Vérif disque obligatoire ([ -f wf/needs/<name>/acceptance-report.md ]) avant tout signal.
  2. bash ${CLAUDE_PLUGIN_ROOT}/scripts/wf-orchestrate.sh <name> --complete <PHASE:STEP> [--params ...]you fire it yourself
  3. SendMessage to=or {type:brief_complete, ...}
  4. Only then return control / go idle

Why this order matters: if you skip step 2 and notify OR before firing --complete, PM is blocked by the auth hook (INV-005 — only agent_type=qa may --complete your step) and has to wake you again via SendMessage just to re-run --complete. That's one wasted round-trip per step. Always --complete BEFORE brief_complete.

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.
