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: 10 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 | $0.00038 | $0.04650 |
| Opus 5.5 | $0.00015 | $0.01860 |
| Sonnet 5.5 | $0.00008 | $0.00930 |
| Haiku 4.5 | $0.00004 | $0.00465 |
Grade A, and why
domain-discovery 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 1mo 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 — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Domain Discovery & Maintainer Interview
You are extracting domain knowledge for a library to produce a structured domain map. Your job is not to summarize documentation — it is to build a deep understanding of the library first, then use that understanding to surface the implicit knowledge that maintainers carry but docs miss.
The output is a set of task-focused skills — each one matching a specific developer moment ("implement a proxy", "set up auth", "audit before launch"). Domains are an intermediate conceptual grouping you use during analysis; the final skills emerge from the intersection of domains and developer tasks.
There are five phases. Always run them in order — unless the lightweight path applies (see below).
- Quick scan — orient yourself (autonomous)
- High-level interview — extract the maintainer's task map
- Deep read — fill in failure modes and detail (autonomous)
- Detail interview — gap-targeted questions, AI-agent failures
- Finalize artifacts
Lightweight path (small libraries)
After Phase 1, decide whether the library warrants the full five-phase flow or the compressed flow below. This is a judgment call — lean toward full discovery unless the library is obviously small (single-purpose utility, 2–3 distinct developer tasks max). Use a compressed flow when the skill surface is small enough that two interview rounds would be redundant:
- Phase 1 — Quick scan (same as full flow)
- Phase 2+4 combined — Single interview round. Combine the high-level task map questions (Phase 2) with gap-targeted and AI-agent-specific questions (Phase 4) into one interview session of 4–8 questions total. Skip the draft-review step since the skill set is small enough to confirm in one pass.
- Phase 3 — Deep read (same as full flow, but scope is smaller)
- Phase 5 — Finalize artifacts (same as full flow)
The lightweight path produces identical output artifacts (domain_map.yaml and skill_spec.md). It just avoids two separate interview rounds when the library is small enough that one round covers everything.
What ships with it
2 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.

domain-discovery is a skill published in the GitHub repository TanStack/intent (355 stars, last pushed 7d ago), licensed MIT. It adds 38 tokens to every session and 4,650 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
