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 5.1 | $0.00069 | $0.00558 |
| Opus 5.5 | $0.00028 | $0.00223 |
| Sonnet 5.5 | $0.00014 | $0.00112 |
| Haiku 4.5 | $0.00007 | $0.00056 |
Grade A, and why
react 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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React
Describe the React task directly, for example: “Review effect cleanup in
packages/admin” or “Migrate packages/web from React 18 to React 19.”
Optional review or migrate prefixes express the same tasks.
- Target. Read target-selection.md, then resolve the package/subproject and React version from explicit task inputs and that package's evidence. Complete its clarification gate before reading a version resource or taking a version-dependent action.
- Load. For a resolved React 18 target, read 18.md. For React 19, read 19.md. Read both only for an explicit 18-to-19 migration or multiple resolved targets, and group notes by target. Load only the selected resource; the links are a menu, not a preload list.
- Apply. Match root APIs, effects, hooks, and migration traps to the selected target and requested change. Keep Next.js framework decisions in the separate Next.js family. A React task can finish from this directory without finding another skill or an ambient repository document.
- Verify. Report the package path, target/version evidence (including an
intentional override), selected references, recommendations or applied
changes, and actual checks. Distinguish guidance from verified runtime
behavior; report unavailable checks as
NOT_RUN.
Resource boundary
Resolve bundled links relative to this skill's real directory. Before loading
a selected resource, verify that it exists and its real path stays within this
directory. Missing, absolute, traversal, or symlink-escaping required resources
return BLOCKED_RESOURCE_MISSING; stop the dependent action without searching
the checkout, predecessor skills, sibling skills, or environment for a copy.
Target project manifests and source files are explicit task inputs, not bundled
fallback resources.
Output
Return target-scoped React guidance or changes, the relevant migration traps, and verification evidence. For unresolved targets, return one grouped clarification and wait; provide no version-specific recommendation yet.
What ships with it
5 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.

react is a skill published in the GitHub repository hmj1026/dhpk (2 stars, last pushed today), licensed MIT. It adds 69 tokens to every session and 558 once invoked, about $0.0003 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 2026-10-16.
