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 | $0.00077 | $0.00656 |
| Opus 5 | $0.00039 | $0.00328 |
| Sonnet 5 | $0.00015 | $0.00131 |
| Haiku 4.5 | $0.00008 | $0.00066 |
Grade A, and why
managing-store-metadata 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 7d 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.

Managing Store Metadata
When to use
| Request | Action |
|---|---|
| "update keywords" | Edit keywords.txt, validate |
| "write description" | Edit description.txt (iOS) or full_description.txt (Android) |
| "release notes" | Edit release_notes.txt for all locales |
| "validate metadata" | Run validate-metadata.js only |
File structure
.msd/metadata/{app-id}/
├── ios/{locale}/
│ ├── name.txt ← 30 chars — INDEXED
│ ├── subtitle.txt ← 30 chars — INDEXED
│ ├── keywords.txt ← 100 chars — INDEXED (comma,no,spaces)
│ ├── description.txt ← 4,000 chars — NOT indexed on iOS
│ ├── promotional.txt ← 170 chars — NOT indexed
│ └── release_notes.txt ← 4,000 chars
└── android/{locale}/
├── title.txt ← 30 chars — INDEXED
├── short_description.txt ← 80 chars — INDEXED
├── full_description.txt ← 4,000 chars — INDEXED (include keywords!)
└── release_notes.txt ← 500 chars (NOT 4,000 like iOS)
Steps
- Confirm which locales to update:
cat .msd/config/{appId}.config.json - Edit the relevant
.txtfiles under.msd/metadata/{appId}/ - Always validate after editing:
node skills/managing-store-metadata/scripts/validate-metadata.js {appId} - Fix any ❌ errors before uploading
- Upload:
eas submit --platform ios/eas submit --platform android, or paste directly into App Store Connect / Google Play Console
Critical rules
- Apple description is NOT indexed for search — keywords belong in name, subtitle, keywords.txt
- Google full description IS indexed — include your top keywords naturally 3-5x
- Apple keywords field: comma,no,spaces — spaces waste characters
- Apple subtitle bug: at exactly 30 chars, Apple may not index the last word. Use 29 or fewer.
- Android What's New: 500 chars max (NOT 4,000 like iOS — common mistake)
- validate-metadata.js exits 1 on any limit violation — this blocks CI

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
