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 | $0.00063 | $0.01083 |
| Opus 5 | $0.00032 | $0.00541 |
| Sonnet 5 | $0.00013 | $0.00217 |
| Haiku 4.5 | $0.00006 | $0.00108 |
Grade A, and why
typescript-structure scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TypeScript/JavaScript Structure Analyzer
Analyze TypeScript and JavaScript files to understand their structure without reading full implementations. Uses the TypeScript Compiler API to extract imports, interfaces, types, classes, and functions.
Quick Usage
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" <file.ts>
Supported File Types
.ts- TypeScript.tsx- TypeScript JSX (React).js- JavaScript.jsx- JavaScript JSX.mts,.mjs- ES Modules.cts,.cjs- CommonJS
Output Formats
| Format | Use Case | Token Cost |
|---|---|---|
skeleton (default) |
Code outline with { ... } bodies |
Low |
signatures |
Just function/interface/class signatures | Very Low |
json |
Structured data for processing | Medium |
detailed |
Full structure with JSDoc | Higher |
Common Commands
Get file structure (default skeleton):
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" src/components/App.tsx
Get just signatures (ultra-compact):
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" src/api.ts --format=signatures
Focus on a specific interface:
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" src/types.ts --interface=UserConfig
Focus on a specific class:
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" src/services.ts --class=AuthService
Get JSON for processing:
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" src/models.ts --format=json
Only show interfaces and types:
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" src/types.ts --only=interfaces
Skip JSDoc to save tokens:
node "${CLAUDE_PLUGIN_ROOT}/skills/typescript-structure/dist/cli.js" large_file.ts --no-jsdoc --compact
Options Reference
| Option | Description |
|---|---|
--format=FORMAT |
Output format: skeleton, signatures, json, detailed |
--only=TYPE |
Show only: functions, classes, interfaces, types, imports, enums |
--class=NAME |
Focus on specific class |
--interface=NAME |
Focus on specific interface |
--function=NAME |
Focus on specific function |
--no-jsdoc |
Omit JSDoc comments (saves tokens) |
--no-decorators |
Omit decorators |
-n, --line-numbers |
Include line number annotations |
-m, --max-lines=N |
Truncate output to N lines |
--compact |
Remove blank lines for density |
What ships with it
1 file 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.

typescript-structure is a skill published in the GitHub repository eran-broder/code-structure-plugin (4 stars, last pushed 6mo ago), licensed MIT. It adds 63 tokens to every session and 1,083 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.
