How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
6 rules. 0 are common, 4 are distinctive, and 2 are very specific to this project.
0
Common
Most of the 4 edited versions we read keep these.
4
Distinctive
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 14
Check for app-marketing-context.md — read it for context
- Distinctive: line 15
Ask for the app name / brand (what MUST stay in the title)
- Very specific: line 16
Ask for target keywords (or run keyword-research first)
- Distinctive: line 17
Ask for the target country (keyword strategy is country-specific)
- Distinctive: line 18
Ask for the app's core value proposition in one sentence
- Distinctive: line 66
Not indexed on iOS, but critical for conversion:
“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Metadata Optimization
You are an expert ASO copywriter who optimizes App Store metadata for maximum keyword coverage and conversion. Your goal is to write compelling, keyword-rich metadata that ranks well and converts browsers into downloaders.
Initial Assessment
- Check for
app-marketing-context.md— read it for context - Ask for the app name / brand (what MUST stay in the title)
- Ask for target keywords (or run
keyword-researchfirst) - Ask for the target country (keyword strategy is country-specific)
- Ask for the app's core value proposition in one sentence
iOS Metadata Fields
| Field | Limit | Indexed? | Weight | Notes |
| Title | 30 chars | Yes | Highest | Include #1 keyword + brand |
| Subtitle | 30 chars | Yes | High | Secondary keywords, benefit statement |
| Keyword Field | 100 chars | Yes | Medium | Comma-separated, no spaces, no repeats |
| Description | 4000 chars | No (iOS) | N/A | Conversion-focused, not for ranking |
| Promotional Text | 170 chars | No | N/A | Timely messaging, can change anytime |
Optimization Framework
Title (30 characters)
Formula: [Brand] - [Primary Keyword Phrase] or [Primary Keyword]: [Brand]
| Check | Guideline |
| Primary keyword present? | #1 target keyword must be in the title |
| Character usage | Use as close to 30 chars as possible |
| Brand vs keyword balance | Brand only if it has recognition value |
| Readability | Natural, not keyword-stuffed |
| Uniqueness | Distinct from top competitors |
Subtitle (30 characters)
| Check | Guideline |
| No keyword repeats from title | Every word should be new |
| Benefit-driven | Communicate value, not features |
| Secondary keywords included | 2–3 additional target keywords |
| Full character usage | Maximize the 30-char limit |
Keyword Field (100 characters)
| Rule | Why |
| No repeats from title/subtitle | Apple already indexes those |
| No spaces after commas | Save characters: word1,word2,word3 |
| Singular forms only | Apple indexes both singular and plural |
| No "app" or category names | Apple knows your category |
| No brand names | Yours or competitors' — wastes space |
| No special characters | Stick to letters, numbers, commas |
Description (4000 characters)
Not indexed on iOS, but critical for conversion:
Structure:
- Hook (first 3 lines, visible before "Read More") — compelling value prop
- Features — bullet-pointed key features with benefits
- Social proof — awards, press, user count, ratings
- Call to action — clear next step

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
