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 | $0.00051 | $0.02201 |
| Opus 5 | $0.00026 | $0.01100 |
| Sonnet 5 | $0.00010 | $0.00440 |
| Haiku 4.5 | $0.00005 | $0.00220 |
Grade A, and why
start 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.
How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Guided Onboarding (Mobile App Studio)
Single file written by this skill: production/review-mode.txt (only when the user picks a review mode in Phase 3b).
This is the entry point. It assumes nothing — not the framework, not the idea, not the user's experience level. It looks at what is on disk, asks the user where they are, then hands off.
Purpose / When to Run
Run when:
- The repo has just been cloned and nothing has been authored yet
- The user types
/startto re-orient - A returning collaborator wants a clean route into the right next step
Do not run when the project is mid-sprint and the user has a clear active task — /help or /sprint-status are better.
Inputs

Outputs
production/review-mode.txt— only written if not present and the user makes a choice in Phase 3b
Phase 1: Silent State Probe
Do this without narrating. The findings only inform recommendations; they are not the conversation opener.
Check:
- Framework configured? Read
.claude/docs/technical-preferences.md. If the Framework field still contains[TO BE CONFIGURED], the framework is not pinned. - Concept exists? Glob for
design/concept.md. - PRDs exist? Count files matching
design/prd/*.md. - Source code present? Glob for any of:
src/**/*.ts,src/**/*.tsx,lib/**/*.dart,ios/**/*.swift,app/src/main/**/*.kt,**/*.swiftexcluding Pods. - Production work in flight? Count files in
production/sprints/andproduction/epics/. - Review mode set? Glob
production/review-mode.txt.
Hold these as facts to validate the user's self-assessment in Phase 4.
Phase 2: Ask Where the User Is
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.

start is a skill published in the GitHub repository cenconq25/claude-code-app-studio (40 stars, last pushed 4mo ago), licensed MIT. It adds 51 tokens to every session and 2,201 once invoked, about $0.0003 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 2026-09-03.
