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 | $0.00068 | $0.03362 |
| Opus 5 | $0.00034 | $0.01681 |
| Sonnet 5 | $0.00014 | $0.00672 |
| Haiku 4.5 | $0.00007 | $0.00336 |
Grade A, and why
expo-launchpad-contract 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 12d 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 — 289 lines — stays where its author put it; the contents beside it link to each section on GitHub.
expo-launchpad-contract
Phase A, step 4 of the expo-launchpad pipeline. Reads the PRD, the design doc, and config.md,
proposes verifiable completion criteria (Mandatory Hard Gates + Platform-Robustness Gates +
Functional Criteria), and marks the contract AGREED before handing off to the generator.
All file schemas (config.md, state.md, contract.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_name |
Contract title header |
app_slug |
Used to identify the app/game |
kind |
app or game — selects which project directories the anti-stub grep and Hard Gate 4 target |
strict_mode |
If true, run --strict negotiation; if false (or absent), run default 1-pass |
If config.md does not exist, abort with:
expo-launchpad-contract: docs/harness/config.md not found — run the orchestrator to bootstrap first.
2. Read the latest PRD
Find the most recent file matching docs/harness/plans/*-prd.md (sort by filename descending,
take the first). Abort with a clear message if none exists.
3. Read the latest design doc
Find the most recent file matching docs/harness/plans/*-design.md (sort by filename descending,
take the first). Abort if none exists.
Mandatory Hard Gates
These 8 criteria are non-negotiable and must appear verbatim in every contract.md. A FAIL on
any one results in an immediate FAIL verdict, regardless of other passing criteria.
Source:
docs/harness-protocol.md§3 — Mandatory Hard Gates block. Always cite; never restate differently.
tsc --noEmitandexpo lintreturn zero errors.jest— all tests pass.- No TODO, stub, or placeholder in app/game logic (grep-checkable).
- All tuning constants centralized in
config/gameConfig.ts(game) /config/appConfig.ts(app) — no magic numbers in feature code. - Content (levels/enemies/screen data) is defined as data, not hardcoded.
- Localization complete for all configured locales — no missing i18n keys.
- Core loop/flow works end to end (game: start→play→win/lose→restart; app: the primary journey).
- Runs on a simulator with zero crashes and zero console errors.
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-contract is a skill published in the GitHub repository SummerRiversound/expo-launchpad (2 stars, last pushed 1mo ago), licensed MIT. It adds 68 tokens to every session and 3,362 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 2026-08-31.
