Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Effect 4 Apply Effect 4 semantics from project-local architecture, the narrowest relevant reference, and source matching the target's installed packages. ## Workflow Do not activate this workflow merely because a file imports `effect`. For nontrivial Effect work: 1. Resolve the target package or workspace and its exact installed `effect` and relevant `@effect/*` versions. If `effect` is not 4.x, stop because this skill does not apply. For 3.x, point the user to the v3 skill: `npx skills add PaulRBerg/agent-skills#shelved --skill effect-ts-v3`. 2. Confirm lockstep versions: every `@effect/*` package must match the installed `effect` version exactly. Report a mismatch instead of coding around it. 3. Inspect neighboring services, layers, errors, schemas, runtime boundaries, and tests. Local conventions decide organization. Installed package evidence decides API facts. 4. Read `references/critical-rules.md`, then only the task-specific references below. 5. Verify every uncertain import, signature, or behavior against the package installation visible to the target workspace before editing. Do not port v3 names from memory. Many were renamed or removed. …

How to install
mdr add paulrberg/agent-skills/effect-ts@sha256:a091e35cdfc6a5a8The line at the top of this page pins the label git:20261019.e444ac2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
