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 | $0.00046 | $0.00890 |
| Opus 5.5 | $0.00018 | $0.00356 |
| Sonnet 5.5 | $0.00009 | $0.00178 |
| Haiku 4.5 | $0.00005 | $0.00089 |
Grade A, and why
architecture-builder 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.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architecture builder
Produce docs/20-architecture.md and docs/21-engineering-principles.md from docs/00-vision.md + docs/10-prd.md.
docs/20-architecture.md sections
- Platform decision — iOS / Android / both, with order if sequential.
- iOS stack —
- Swift version (latest stable)
- Minimum iOS target — resolve
knowledge/stack-defaults.md's relative rule (flagship = latest major minus one) to a concrete number here, and record how you resolved it - UI: SwiftUI by default; UIKit only if PRD demands something SwiftUI struggles with
- State:
@Observable+@MainActoron ViewModels only (Combine /@Published/ObservableObjectare forbidden —knowledge/ios-conventions.md) - Networking: URLSession + async/await, or a named lib
- Persistence: SwiftData (content apps) or GRDB+SQLite/FTS5 (camera/media) — pick by PRD complexity
- DI: lightweight — protocol + initializer injection
- Testing: Swift Testing (
@Test/@Suite) for unit and domain tests, not XCTest. UI automation stays XCUITest — it is XCTest-based, has no Swift Testing equivalent, andruntime-gateruns it, so a blanket "never XCTest" would ban the suite the release gate expects. Name the snapshot lib. State the coverage floor for the pure-Swift domain engine package (knowledge/stack-defaults.md)
- Android stack —
- Kotlin version
- minSdk / targetSdk (set based on PRD users)
- UI: Jetpack Compose
- Architecture: MVVM or MVI, picked once
- Networking: Retrofit + OkHttp + Kotlinx Serialization (or named alternative)
- Persistence: Room (or named alternative)
- DI: Hilt (flagship) or Koin (utility tier)
- Async: Coroutines + Flow
- Testing: JUnit, Turbine, MockK, Paparazzi (screenshot), Compose UI test
- Shared concerns — auth, analytics, crash reporting, feature flags, remote config, push.
- Backend interface — sketch the APIs the apps need. If backend is in scope, name the service shape.
- Repository layout —
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.
- 1mo ago First seen · 69 lines · 46 tokens per session scan A 70994a3939a6
architecture-builder is a skill published in the GitHub repository vmobifystudio/app-dev-team (4 stars, last pushed 4d ago), licensed MIT. It adds 46 tokens to every session and 890 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.

execute-task
Implement one task (or a cohesion bundle) from a signed-off spec (Ready or Active): recompute the execution freshness gate, write the verifying test first, implement to green, run the project's full CI with adaptive retry, converge via the stepsconvergence list (default /polish --nested), then open a draft PR…
orchestrate
Advance one planwright spec by one step: pick the next ready unit critical-path-first (or a cohesion bundle), run the freshness gate, record the dispatch under the per-spec lock, and dispatch /execute-task via the backend. A stateless, disposable orchestrator session; a reconcile sweep rebuilds from disk. Never…
spec-kickoff
Walk a spec bundle section by section to mutual understanding, producing the signed-off kickoff brief downstream skills execute from. On sign-off: runs the Discovery-Rigor lens pass, flips Draft to Ready, records the sign-off record (anchor last), commits, pushes, opens a draft PR, then on clean completion marks the…

The front door: a standing conversational session that takes any ask about the repository in plain language, answers questions, and routes work that changes the repository per request onto visual flight (an isolated worker that lands a draft PR) or instrument flight (the spec pipeline), stating its grounds, with…

Autonomous act-then-review convergence loop: iterate /self-review passes, draining every action disposition (Auto-applicable and Agent-resolvable applied, Needs-sign-off applied on the branch) until only irreducible Needs-human-judgment forks remain, then hand off a projection of the audit record plus the…

Drive a live Appium session from the shell with the aco CLI.
