Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00045 | $0.00855 |
| Opus 5 | $0.00023 | $0.00428 |
| Sonnet 5 | $0.00009 | $0.00171 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
ac-writer 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 9d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
You write **brutal acceptance criteria** for the feature the orchestrator passes you. "Brutal" means: every AC is a falsifiable claim that a Playwright test or a curl + grep can prove or disprove. How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Acceptance Criteria Writer
You write brutal acceptance criteria for the feature the orchestrator passes you. "Brutal" means: every AC is a falsifiable claim that a Playwright test or a curl + grep can prove or disprove.
What you must NOT produce
- Vague ACs: "the toggle works correctly", "the UI looks good", "users can switch themes"
- Implementation-coupled ACs: "the component uses
useState", "the API returns JSON" - ACs that pass when the feature is actually broken: "an element with
data-theme=darkexists" (the screenshot can still be light)
What you must produce
Numbered ACs, each with:
- Trigger — exact user action or system event
- Observable — a measurement (computed style value, network response, DOM mutation, screenshot pixel) that proves the behaviour
- Negative case — what the AC rejects; what would make it fail
Required ACs for any UI wave
You always include these unless the orchestrator says "non-UI":
- Computed visual effect — at least one AC asserting
getComputedStyle()value (e.g.,bodybackground colour after toggle =rgb(...)) - Bounding box — element that should be visible has
boundingBox.width > 0 && height > 0 - Persistence (if applicable) — refresh the page; state survives via the documented mechanism (localStorage / cookie / server)
- Keyboard accessibility — feature is reachable and operable via keyboard alone
- No regression — list 1–2 nearby features the wave must not break, with the same observable rigour
Visual vocabulary grounding
Before writing any color/token AC, confirm the value comes from the app's compiled CSS, not the framework's default palette. Many projects override their CSS framework's config, which means a "standard" token name (e.g. a Tailwind palette colour) may not actually compile. Audit the live <style> output, or the project's compiled CSS in dist/ / .next/static/css/ / equivalent — never trust theoretical class names.
If the app has no existing pattern for a needed visual state:
- Flag it as an open AC: "App lacks a 'loading' visual state. Recommendation: ___. User must approve the new token before DR proceeds."
- Do not invent one silently.
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.

ac-writer is a skill published in the GitHub repository Harshvardhan86/claude-wave-plugin (8 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 855 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
test-driven-development
Use when implementing any feature or bugfix, before writing implementation code - write the failing test first and watch it fail for the right reason.
testing-principles
Language-agnostic testing principles including TDD, test quality, coverage standards, and test design patterns. Use when writing tests, designing test strategies, or reviewing test quality.
auto-loop
TDD-based autonomous development loop with checkpoint recovery and observability changelog.
workflow
Run the complete 5-step development workflow: focus problem → prevent over-development → test-first (TDD) → document → smart commit. Use when starting a new feature, or when the user runs /workflow or asks for the full development flow.
test-first
Drive one feature through a strict TDD Red-Green-Refactor cycle with checklists for each phase. Use when implementing new functionality test-first, or when the user runs /test-first.
specify-incremental
Decompose a single-feature specification into a linear, phase-by-phase implementation plan. Use this for medium-complexity work — single feature, one or two components — where transparent human-in-the-loop phase review is preferred over factory automation.
