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 | $0.00082 | $0.04003 |
| Opus 5 | $0.00041 | $0.02001 |
| Sonnet 5 | $0.00016 | $0.00801 |
| Haiku 4.5 | $0.00008 | $0.00400 |
Grade A, and why
expo-launchpad-plan 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 11d 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 — 459 lines — stays where its author put it; the contents beside it link to each section on GitHub.
expo-launchpad-plan
Phase A, step 2 of the expo-launchpad pipeline. Reads the research spec and config.md, decides the
app identity, writes a comprehensive PRD in the project's default_language (branching structure
on kind), maps the project directory structure, and advances the pipeline state to design.
All file schemas (config.md, state.md, pipeline-log.md) are defined in
docs/harness-protocol.md — refer to that document as the single source of truth. Do not redefine
schemas here.
Input
1. Read docs/harness/config.md
Extract:
| Key | Use |
|---|---|
app_idea |
Refined concept tagline written by the research phase |
app_name |
Display name (blank — this skill sets it) |
app_slug |
Kebab-case identifier (blank — this skill sets it) |
bundle_id |
App bundle ID (blank — this skill sets it) |
kind |
game or app — drives which PRD structure and structure map is written |
engine |
skia — the only supported Phase A value, meaningful only when kind: game; cited in the PRD's mechanics/structure sections |
default_language |
The user's conversation language; the PRD and all copy are written in it |
orientation |
Currently portrait (bootstrap default) — this skill may revise it |
If config.md does not exist, abort with:
expo-launchpad-plan: docs/harness/config.md not found — run the orchestrator to bootstrap first.
2. Read the latest research spec
Find the most recent file matching docs/harness/specs/*-research.md (sort by filename descending,
take the first). If no spec file exists, abort with:
expo-launchpad-plan: no research spec found in docs/harness/specs/ — run expo-launchpad-research first.
Extract from the spec:
- Chosen Concept — title, tagline, core mechanic / primary journey, differentiator
- Monetization hook — one-line note only; the mechanism and any SDK/config are deferred to Phase B (never design monetization implementation here)
- Clone-Avoidance Check — must read
SAFEorCLONE (resolved). If it reads anything else (missing, unresolvedCLONE, or malformed), do not proceed — see Error handling.
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.

expo-launchpad-plan is a skill published in the GitHub repository SummerRiversound/expo-launchpad (2 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session and 4,003 once invoked, about $0.0004 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.
