Inspect package/upstream source with opensrc: internals, exact paths, version diffs, and upgrade audits for npm, PyPI, crates, and Git; not general web.
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
# Opensrc Use this skill when source-level dependency inspection materially changes the answer. Prefer docs and types first; pull source when behavior, migration risk, or implementation details matter. ## Core Workflow 1. Read the repo `AGENTS.md` and inspect relevant manifests and lockfiles. 2. Use the global `opensrc` binary. Fall back to `bunx opensrc` only if the binary is unavailable. 3. Use `opensrc fetch` when the goal is cache-only prep: ```bash opensrc fetch --cwd <repo-root> zod react next opensrc fetch <pkg>@<current_version> <pkg>@<target_version> ``` 4. Use `opensrc path` when the next command needs a filesystem path: ```bash rg "pattern" "$(opensrc path zod)" cat "$(opensrc path zod)"/src/types.ts find "$(opensrc path pypi:requests)" -name "*.py" git diff --no-index "$(opensrc path <pkg>@<current>)" "$(opensrc path <pkg>@<target>)" ``` 5. Cite exact versions and local source paths when source evidence affects the recommendation. 6. Use web/docs sources for release notes, API references, changelogs, and migration guides; use `opensrc` for implementation internals and source diffs. ## Version Guardrails …

How to install
mdr add bjornmelin/dev-skills/opensrc@sha256:503d6c4cbc5576f6The line at the top of this page pins the label git:20260905.b7d83c3, 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.
