opensrc SKILL.md skillA

opensrc from canvascoding/canvas-notebook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add canvascoding/canvas-notebook/opensrc@git:20260415.c9cbc93

Pins git:20260415.c9cbc93 in mdr.lock. Pin the fingerprint instead.

Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for", "read the source of", "how does X work internally", "get the implementation of", "opensrc path", or any task requiring access to dependency source code beyond types and docs.

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

# Source Code Fetching with opensrc

Fetches dependency source code so agents can read implementations, not just types. Clones repositories at the correct version tag and caches them globally at `~/.opensrc/`.

## Core Pattern

```bash
rg "parse" $(opensrc path zod)
cat $(opensrc path zod)/src/types.ts
find $(opensrc path zod) -name "*.test.ts"
```

`opensrc path <pkg>` prints the absolute path to cached source. If not cached, it fetches automatically. Progress goes to stderr, path to stdout, so `$(opensrc path ...)` works in subshells.

## Fetching Source Code

```bash
opensrc path zod
opensrc path pypi:requests
opensrc path crates:serde
opensrc path facebook/react

# Multiple packages at once
opensrc path zod react next
opensrc path pypi:requests pypi:flask
opensrc path crates:serde crates:tokio

# Specific versions
opensrc path zod@3.22.0
opensrc path pypi:flask@3.0.0
opensrc path owner/repo@v1.0.0
opensrc path owner/repo#main
```

### Version Resolution

For npm packages, opensrc auto-detects the installed version from lockfiles (`package-lock.json`, `pnpm-lock.yaml`, `yarn.lock`). Use `--cwd` to resolve from a different project:

```bash
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add canvascoding/canvas-notebook/opensrc@sha256:63b69ae45e5ebc88

The line at the top of this page pins the label git:20260415.c9cbc93, 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.
