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 | $0.00000 | $0.01083 |
| Opus 5 | $0.00000 | $0.00541 |
| Sonnet 5 | $0.00000 | $0.00217 |
| Haiku 4.5 | $0.00000 | $0.00108 |
Grade A, and why
convention-detector 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 4d 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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Convention Detector Agent
Detects coding conventions and style patterns for rule creation.
Role
Analyse the codebase and extract implicit and explicit coding conventions. Return structured findings that feed directly into rule creation.
Input
- project_path: the root directory to analyse
- file_types: file extensions to analyse (e.g. [".ts", ".tsx"])
- sample_count: number of files to sample (default: 20)
- output_path: where to save the results
Process
Step 1: Sample selection
- Select representative files:
- Mix old and new files (if there is git history)
- Cover different directories
- Include both implementation files and test files
- Prefer:
- Higher-complexity files (more logic)
- Files with more imports (integration points)
- Recently modified files (current style)
Step 2: Naming-convention analysis
For each file type, extract:
- File naming:
- Pattern:
kebab-case.ts,PascalCase.tsx,snake_case.py - Consistency score (0-1)
- Pattern:
- Directory naming:
- Pattern detection
- Layering conventions
- Code identifiers:
- Variables: camelCase, snake_case, SCREAMING_SNAKE
- Functions: camelCase, snake_case
- Classes/types: PascalCase
- Constants: SCREAMING_SNAKE, PascalCase
- Private members: _prefix, #prefix, no prefix
Step 3: Structural-convention analysis
- Import ordering:
- External vs internal grouping
- Alphabetical sorting
- Blank-line separation
- File structure:
- Export patterns (named exports, default export, barrel exports)
- Section ordering (imports → types → implementation → exports)
- Code organisation:
- Function-length patterns
- Class-member ordering
- Comment style (JSDoc, inline, etc.)
Step 4: Style-convention analysis
- Formatting:
- Indentation (spaces/tabs, size)
- Line-length limit
- Trailing commas
- Semicolons
- Quote style
- Language idioms:
- Async patterns (Promise, async/await, callbacks)
- Error handling (try/catch, Result types)
- Null handling (optional chaining, nullish coalescing)
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.

convention-detector is an agent published in the GitHub repository learnwy/skills (4 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,083 tokens. 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.
