release

A release checklist for the Lading Rust project. It updates the change log and version files, verifies the dependency lockfile, then prepares a branch, commit, and pull request.

In plain words
What is it for?
Use it to prepare a versioned release, choosing a semantic-version change based on whether the updates are breaking.
Why use it?
It reduces the chance of missing a required file or step when publishing a new software version.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

release scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Release process for lading

1. Determine the next version

  • Read lading/Cargo.toml and CHANGELOG.md to find the current version and unreleased changes.
  • If the user hasn't specified a version, suggest one based on semver:
    • Breaking changes in the unreleased section -> bump minor (we're pre-1.0).
    • Otherwise bump patch.
  • Confirm the version with the user before proceeding.

2. Create a release branch

  • Create a branch from main: git checkout -b prepare-release-v<version>

3. Update CHANGELOG.md

  • Read CHANGELOG.md.
  • Insert a new ## Unreleased header (with empty subsections) above the current unreleased content.
  • Rename the existing unreleased content block to ## [<version>].
  • Ensure there is a blank line between the new empty ## Unreleased and ## [<version>].

4. Bump version in Cargo.toml

  • Edit lading/Cargo.toml to set version = "<new_version>".

5. Update Cargo.lock

  • Run cargo check to propagate the version change into the lockfile without re-resolving all dependencies.

6. Commit and create PR

  • Stage CHANGELOG.md, lading/Cargo.toml, and Cargo.lock.
  • Commit with message: release: v<version>
  • Push the branch and create a PR targeting main.

7. Tag after merge

  • After the PR is merged, remind the user to tag the merge commit on main:
    • git checkout main && git pull
    • git tag -a v<version> -m "v<version>"
    • git push origin v<version>
  • NEVER use git push --tags — always push exactly one tag at a time.
  • The release.yml GitHub Actions workflow will automatically create a GitHub Release from the tag, pulling notes from CHANGELOG.md.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

release is a skill published in the GitHub repository DataDog/lading (98 stars, last pushed 4d ago), licensed MIT. It adds 31 tokens to every session and 482 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
