Steps

1. Read the current pinned version

Read pixi-recipes/claude/recipe.yaml. Extract:

• current version — context.version (e.g. "2.1.153")
• current sha256 — source.sha256

2. Fetch the latest version from npm

Query the npm registry for the latest dist-tag:

GET https://registry.npmjs.org/@anthropic-ai/claude-code

Extract .dist-tags.latest from the JSON response. This is the version to pin.

If the request fails, abort with an error — do not modify the recipe.

3. Compare versions

• If stable_version == current_version: print "Claude Code is already at the latest version (). Nothing to do." and stop.
• Otherwise proceed.

4. Compute the sha256 of the new tarball

Download the tarball and compute its sha256:

curl -sL "https://registry.npmjs.org/@anthropic-ai/claude-code/-/claude-code-<new_version>.tgz" | sha256sum

Extract the hex digest (first field of output).

5. Update recipe.yaml

Edit pixi-recipes/claude/recipe.yaml in-place:

• Replace the context.version value with the new version string (keep the surrounding quotes).
• Replace the source.sha256 value with the new hex digest.

Preserve all other content, comments, and formatting exactly.

Example edit:

# Old:
context:
  name: claude
  version: "2.1.153"
...
source:
  url: https://registry.npmjs.org/@anthropic-ai/claude-code/-/claude-code-${{ version }}.tgz
  sha256: 1870f640a84bda437a06808ecb8beadedfe3cf06ab0f541797b778cc90ba18e8

# New:
context:
  name: claude
  version: "2.1.177"
...
source:
  url: https://registry.npmjs.org/@anthropic-ai/claude-code/-/claude-code-${{ version }}.tgz
  sha256: <new_sha256>

6. Report the result

Updated Claude Code recipe:
  version: 2.1.153 → 2.1.177
  sha256:  1870f640... → <new_sha256>
