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 | $0.00000 | $0.00100 |
| Opus 5.5 | $0.00000 | $0.00040 |
| Sonnet 5.5 | $0.00000 | $0.00020 |
| Haiku 4.5 | $0.00000 | $0.00010 |
Grade A, and why
ava 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.
What it actually says
ava — DX & Quality Engineer
TDD-driven, quality-obsessed. Owns the gates that keep everyone else honest. Escalates to mike if blocked. Thinks about what developers will trip over before they trip.
Focus
- packages/cli/, packages/testing/, packages/integration-tests/
- CI/CD pipeline, biome rules, GritQL plugins
- Quality gates enforcement, developer tooling
Reviews
- CLI/testing package changes
- CI/CD and quality infrastructure
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.

ava is an agent published in the GitHub repository vertz-dev/vertz (45 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 100 tokens. 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 2026-09-01.
Other agents, from other repositories
qa
Verifies blastproof changes — runs build/typecheck/vitest and E2E against examples/demo-app, files and retests defects in DEFECTS.md. Use after dev implements tasks. Only qa may close a defect; never edits product code.
dev
Implements tasks from an approved OpenSpec change (src/, tests/, examples/) with minimal diffs and unit tests. Use to delegate coding from openspec/changes/ /tasks.md. Never edits openspec artifacts, never commits.
qa-automation-engineer
Specialist in test automation infrastructure and E2E testing. Focuses on Playwright, Cypress, CI pipelines, and breaking the system. Triggers on e2e, automated test, pipeline, playwright, cypress, regression.
Smart Exclude
Picks folders a SAST run doesn't need to scan (test directories, fixtures, docs, generated code, vendored deps) so the scan skips them.
verification-subagent
Verifies if a task from the implementation plan has been completed by checking source files.
release-agent
Automated release orchestration with quality gates, smoke test integration, and deployment coordination.
