A verification workflow that runs a project’s defined tests and stops when a check fails. It distinguishes a fast local test loop from the full test battery required before committing.

Use it to discover the project’s test commands, run unit, property, lint, integration, and Docker-based checks as required, and verify a green result before committing.

It prevents committing or claiming that work is complete when the project’s required checks are failing or have not been run.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00136	$0.01451
Opus 5	$0.00068	$0.00726
Sonnet 5	$0.00027	$0.00290
Haiku 4.5	$0.00014	$0.00145

Security

Grade A, and why

test-gate 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 6d 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.

Test Gate — verify before commit, block on red

Overview

Run the project's full Tier-B battery, read the real output, and stop the moment anything is red — never commit a red tree, never claim "passing" you did not watch pass. The strategy this enforces is the project's docs/TESTING.md. Invocation is the authorization — run end-to-end without a confirm prompt.

This is the project's concrete runner, built from its own commands and infra. Closing ritual: test-gate green, then commit, then /generate-pr.

Arguments & modes

$1 = full (default) — the Tier-B PR-gated battery (what blocks a commit/merge).
$1 = fast — Tier-A local loop (unit + property + lint), skips Docker/integration for a tight feedback cycle. fast green is not sufficient to commit — run full before committing.

Step 0 — Discover the commands (deterministic — never guess them)

Read the source of truth; do not invent commands:

sed -n '/## Commands/,/^## /p' CLAUDE.md         # the canonical command list
cat docs/TESTING.md                              # tiers, kinds, the Docker infra block, the gate order
ls docker-compose*.y*ml 2>/dev/null              # is there hermetic infra to bring up?

Map what you find to the gate stages and set a shell var per stage from the real discovered command — $LINT, $TYPECHECK, $TEST (the Tier-B suite), $E2E, and $MIGRATE / $SEED for infra. If a stage has no command in this project, leave its var empty, skip it, and say so in the report (an honest "no e2e configured" — never a silent pass). Never read or print .env or secrets: to check a needed var, test presence only ([ -n "$VAR" ] && echo set).

Step 1 — Bring up hermetic infra (only if a compose file exists)

COMPOSE=$(ls docker-compose.test.y*ml docker-compose.y*ml 2>/dev/null | head -1)
if [ -n "$COMPOSE" ]; then
  docker compose -f "$COMPOSE" up -d --wait        # wait for healthchecks; don't race startup
  trap 'docker compose -f "$COMPOSE" down -v' EXIT # ALWAYS tear down + drop volumes, even on failure
  [ -n "$MIGRATE" ] && eval "$MIGRATE"; [ -n "$SEED" ] && eval "$SEED"   # deterministic schema + fixtures
fi

test-gate is a skill published in the GitHub repository gabrieldabbah/genesis (4 stars, last pushed 1mo ago), licensed MIT. It adds 136 tokens to every session and 1,451 once invoked, about $0.0007 per session on Opus 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 2026-08-31.

fleet

Parallel campaign orchestrator. Runs multiple campaigns in coordinated waves within a single session. Spawns 2-3 agents per wave in isolated worktrees, collects discoveries, shares context between waves. Use when work decomposes into 3+ independent streams that can run simultaneously.

Continuous autonomous operation mode. Keeps campaigns running 24/7 by chaining Claude Code sessions via RemoteTrigger. Each session picks up from the campaign's continuation state, works until context runs low or the phase completes, then schedules the next session. Auto-stops on campaign completion or budget…

Research-driven multi-cycle improvement director. Forms causal hypotheses about why scores are low, validates them with scout agents before attacking, dispatches axis-parallel fleet attacks, extracts transferable patterns, and runs indefinitely within a budget envelope. Accumulates a persistent belief model and…

Autonomous quality improvement loop. Scores a target against a rubric, selects the highest-leverage axis, attacks it, verifies, documents, and loops. No pre-planning between iterations — each loop re-scores from scratch.
