wrdn-effect-atom-reactivity-keysAdd reactivityKeys to effect-atom write mutation calls. An agent skill from UsefulSoftwareCo/executor.
Wrdn Effect Atom Reactivity Keys is an agent skill from UsefulSoftwareCo/executor. Add reactivityKeys to effect-atom write mutation calls. Use when lint flags a useAtomSet mutation call that mutates data without invalidation keys.
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: The missing integration layer for AI agents. Let them call any OpenAPI / MCP / GraphQL / custom js functions in secure environment. The licence is MIT.
Read from SKILL.md and the folder at commit 9ef04e9. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobBashFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Wrdn Effect Atom Reactivity Keys loads about 204 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 61 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Grep, Glob, BashAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Add reactivityKeys to effect-atom write mutation calls. An agent skill from UsefulSoftwareCo/executor. Wrdn Effect Atom Reactivity Keys is an agent skill from UsefulSoftwareCo/executor. Add reactivityKeys to effect-atom write mutation calls.
Wrdn Effect Atom Reactivity Keys fits situations like: lint flags a useAtomSet mutation call that mutates data without invalidation keys.
Run `npx skills add UsefulSoftwareCo/executor --skill wrdn-effect-atom-reactivity-keys -a claude-code`. Or copy the skill folder (.agents/skills/wrdn-effect-atom-reactivity-keys in UsefulSoftwareCo/executor) into .claude/skills/wrdn-effect-atom-reactivity-keys in your project. Claude Code loads it when a task matches its description.
Run `npx skills add UsefulSoftwareCo/executor --skill wrdn-effect-atom-reactivity-keys -a codex`. Or copy the skill folder (.agents/skills/wrdn-effect-atom-reactivity-keys in UsefulSoftwareCo/executor) into .agents/skills/wrdn-effect-atom-reactivity-keys in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add UsefulSoftwareCo/executor --skill wrdn-effect-atom-reactivity-keys -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/wrdn-effect-atom-reactivity-keys, .gemini/skills/wrdn-effect-atom-reactivity-keys, .github/skills/wrdn-effect-atom-reactivity-keys and .opencode/skills/wrdn-effect-atom-reactivity-keys in your project.
SKILL.md names no scripts, command-line tools or credentials: Wrdn Effect Atom Reactivity Keys is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Glob, Bash.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Wrdn Effect Atom Reactivity Keys is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 204 tokens (SKILL.md is roughly 816 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
