## What it does

This skill puts the `antithesis-triage` skill through its paces. The top-level agent never triages anything itself. It spawns sub-agents that hit the live Antithesis API through `snouty`, then reads what they actually did.

The workflow runs in four stages: a prerequisite check, run discovery for your tenant, target selection, and a parallel triage round. Two targets get picked — a finished run whose failing properties have moments, and an unfinished one carrying a `failure_moment`. Each target goes to its own sub-agent.

Audit material comes from the raw JSONL sessions under `~/.claude/projects/<project-dir>/<session-id>/subagents/agent-<agentId>.jsonl`. Pulling the Bash calls out of those files with `jq` shows every `snouty` invocation and every failure, so the review rests on command output rather than the sub-agent's own summary. You need `snouty` 0.8.0 or newer plus `jq` on `PATH`; miss either one and the run halts at the preflight check with a list of what is missing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add antithesishq/antithesis-skills --skill test:triage -a claude-code
```
```bash
npx skills add antithesishq/antithesis-skills --skill test-triage -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/test-triage/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/test-triage/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add antithesishq/antithesis-skills --skill test-triage -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/test-triage/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add antithesishq/antithesis-skills --skill test-triage -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/test-triage/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install antithesishq/antithesis-skills test-triage
```

2. **Manually: put the files in place**
- File: `.github/skills/test-triage/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add antithesishq/antithesis-skills --skill test-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/antithesishq/antithesis-skills --path .claude/skills/test-triage
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/test-triage/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add antithesishq/antithesis-skills --skill test-triage -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/antithesishq/antithesis-skills/tree/HEAD/.claude/skills/test-triage/SKILL.md

## When to use it
- exercise the triage skill against a real API instead of fixtures
- catch sub-agent steps that drift from the `antithesis-triage` protocol
- read the actual `snouty` and `jq` calls rather than a recap
- cover both the failing-properties path and the incomplete-run path
- surface papercuts before a user runs into them

## Example prompts
- Run the full test of the `antithesis-triage` skill against real runs for my tenant
- Smoke test triage and then walk the sub-agent traces
- Validate antithesis triage: take one completed run with failing properties and one incomplete run with a `failure_moment`

# Test: Antithesis Triage Skill

End-to-end test harness for the `antithesis-triage` skill. Spawn sub-agents
that perform real triage operations against the live Antithesis API via
`snouty`, then review their work for issues.

**The top-level agent MUST NOT use the antithesis-triage skill directly.**
All triage operations happen inside sub-agents. The top-level agent only
orchestrates and reviews.

## Prerequisites

Before starting, verify the same prerequisites the triage skill requires:

```bash
which snouty && which jq && snouty --version
```

`snouty` must be at least version 0.8.0. Then confirm credentials with the canonical check (same as the triage skill's preflight):

```bash
snouty doctor
```

If any prerequisite is missing, out of date, or `snouty doctor` fails, stop and
report which ones are unavailable.

## Phase 1: Discover Runs

Spawn a **general-purpose sub-agent** with the Agent tool. Provide these
instructions, replacing `{{TENANT}}` with the actual value of the
`$ANTITHESIS_TENANT` environment variable and `{{TRIAGE_SKILL}}` with the
absolute path to `antithesis-triage/SKILL.md` in this repository. If
`$ANTITHESIS_TENANT` is empty in the current shell, ask the user for the tenant
name instead of aborting.

```
Read the skill file at {{TRIAGE_SKILL}} and follow its instructions to list
recent runs for the tenant "{{TENANT}}". Follow the "Summarize recent runs"
workflow.

Return the COMPLETE raw NDJSON of `snouty runs --json list -n 200` along
with a per-run summary that includes, for each run:
  - run_id
  - status
  - launcher
  - created_at / completed_at
  - antithesis.test_name and antithesis.description (from parameters)
  - whether links.triage_report is present (triageable yes/no)

Do NOT filter by status — return the full list so the orchestrator can
select targets across statuses.
```

Wait for this sub-agent to finish before proceeding.

If the sub-agent did not return the NDJSON list, abort.

## Phase 2: Select Test Targets

Read the sub-agent output. From the run listing, select two targets:
