In plain words
What is it for?
Use it to discover test runs, perform triage through separate agents, and review the resulting work for bugs or workflow issues.
Why use it?
It checks the triage workflow end to end using real operations, helping reveal problems in the skill itself.

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

test:triage 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 12d 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.

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:

which snouty && which jq && snouty --version

snouty must be at least version 0.6.0. Then confirm credentials with the canonical check (same as the triage skill's preflight):

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If any prerequisite is missing, out of date, or snouty doctor fails, stop and report which ones are unavailable.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

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.
