difit: Skill for Codex

.codex/skills/vscode-release/SKILL.md

vscode-release is a skill for Codex from yoshiko-pg/difit. It costs 49 tokens per session (488 once invoked), scanned A, original, MIT.

A release workflow for publishing the difit extension for Visual Studio Code, including building and checking a VSIX package. VSIX is the installable file format for VS Code extensions.

In plain words
What is it for?
Use it to build, locally smoke-test, version, commit, tag, and publish the difit VS Code extension.
Why use it?
It reduces the risk of publishing an untested extension or releasing the wrong version. It also requires explicit approval before publishing.

Skill for Codex

Written for Codex: agents/openai.yaml present.

This is yoshiko-pg/difit's own configuration. It tells Codex how to work on difit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything difit configures →

About the project

difit is a command-line tool that starts a local web server showing Git commit differences in a GitHub-style file-change viewer. Developers use it to inspect and review local diffs or pull requests, with review comments that can also be copied into AI prompts. The catalogue entries connect coding-agent workflows to difit for requesting or performing reviews.

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

vscode-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 2mo 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

VS Code Extension Release Workflow

Follow this workflow for the current repository.

Prepare local build verification

  1. Verify release target files in packages/vscode and confirm current branch state.
  2. Run pnpm install --frozen-lockfile.
  3. Run pnpm -C packages/vscode run package.
  4. Read packages/vscode/package.json and confirm the current extension version.
  5. Confirm the VSIX exists at packages/vscode/difit-vscode-<version>.vsix.
  6. Ask the user to smoke test the local VSIX install in VS Code:
    • Install from VSIX.
    • Confirm the difit command opens review correctly.
    • Confirm the toolbar button/icon appears and works.
  7. Ask for explicit OK in Japanese before publishing.

Release after explicit OK

Treat the locally verified build result at OK time as the source of truth. Do not skip rebuilding after version changes.

  1. Bump extension version in packages/vscode/package.json:
    • pnpm -C packages/vscode version patch --no-git-tag-version
  2. Re-run pnpm -C packages/vscode run package and confirm the new VSIX filename.
  3. Commit packages/vscode/package.json with an English message: chore(vscode): release vX.Y.Z.
  4. Create tag vscode-vX.Y.Z.
  5. Push main and tags: git push origin main --tags.
  6. If push is rejected by non-fast-forward:
    • Run git pull --rebase origin main.
    • Retry git push origin main --tags.
  7. Publish to Visual Studio Marketplace:
    • pnpm -C packages/vscode exec vsce publish
    • Use the already bumped version from packages/vscode/package.json.

Output to user

  • Respond in Japanese.
  • Report local build verification result, released version, created tag, and publish result.
  • Mention if any recovery step was required (for example, rebase due to non-fast-forward).

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
