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.

SkillSpector: 7 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00063 | $0.01581 |
| Opus 5 | $0.00032 | $0.00790 |
| Sonnet 5 | $0.00013 | $0.00316 |
| Haiku 4.5 | $0.00006 | $0.00158 |
Grade A, and why
typescript-advanced 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 8d 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.

TypeScript Advanced
Comprehensive TypeScript guidance covering compiler configuration, advanced types, utilities, type narrowing, best practices, and documentation patterns.
When to Apply
Use this skill when:
- Configuring TypeScript compiler (tsconfig.json)
- Working with advanced type features (generics, conditionals, mapped types)
- Creating custom utility types and type guards
- Implementing type-first development workflow
- Making illegal states unrepresentable with discriminated unions
- Implementing runtime validation with Zod
- Generating API documentation with JSDoc/TypeDoc
- Creating architectural decision records (ADRs)
- Debugging complex type errors
- Optimizing type checking performance
Use When
- "Help me do this with strict TypeScript."
- "How should I model this union/generic type?"
- "How do I avoid
anyand unsafe assertions?" - "How do I fix this TypeScript compile error safely?"
Scope
In Scope
- tsconfig and strict-mode guidance.
- Advanced type modeling (generics, conditionals, mapped types).
- Runtime narrowing and type-safe validation patterns.
- TypeScript documentation patterns (JSDoc/TypeDoc, ADRs).
Out of Scope
- End-to-end testing setup.
- Framework build pipeline setup unrelated to TypeScript design.
- Language-agnostic coding standards.
Consolidation Note
This skill consolidates 5 original TypeScript skills (~3,372 lines) into a ~120-line navigation hub with on-demand reference loading:
- typescript-type-system (738 lines) - Compiler config, strict mode, module resolution
- typescript-utility-types (832 lines) - Built-in and custom utility types
- typescript-advanced-types (724 lines) - Generics, conditional types, mapped types, patterns
- typescript-best-practices (270 lines) - Type-first development, illegal states, Zod validation
- typescript-docs (808 lines) - JSDoc, TypeDoc, ADRs, framework-specific documentation
Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| CRITICAL | Compiler & Configuration | Essential foundation | compiler- |
| CRITICAL | Best Practices & Patterns | Type-first workflow | practices- |
| HIGH | Advanced Types | Complex type logic | types-advanced- |

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.
- 8d ago First seen · 229 lines · 63 tokens per session scan A 91d3c2a15996
typescript-advanced is a skill published in the GitHub repository pantheon-org/tekhne (10 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 1,581 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 2026-09-03.
