dart-intellij-third-party: Skill for Claude Code

.agents/skills/monthly-release/SKILL.md

monthly-release is a skill for Claude Code, Codex from flutter/dart-intellij-third-party. It costs 18 tokens per session (1,016 once invoked), scanned A, original, BSD-3-Clause.

A step-by-step procedure for preparing, checking, and publishing the monthly release of the Dart IntelliJ plugin. An IntelliJ plugin adds Dart support to JetBrains development tools.

In plain words
What is it for?
Use it when updating the changelog, reviewing changes since the previous release, testing the plugin, and publishing a new monthly version.
Why use it?
It provides a repeatable release checklist and records user-facing changes in the correct changelog format. It also preserves the project's stated compatibility policy.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is flutter/dart-intellij-third-party's own configuration. It tells Claude Code and Codex how to work on dart-intellij-third-party 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 dart-intellij-third-party configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 33
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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

monthly-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 9d 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.

Monthly Plugin Release Process

Use this skill when preparing, testing, validating, and publishing a new monthly release of the Dart IntelliJ plugin (dart-intellij-third-party).

[!NOTE] Platform Compatibility Policy: untilBuild is intentionally omitted in gradle.properties and build.gradle.kts to maintain open-ended compatibility with future IDE builds without artificial version caps. Do NOT add untilBuild caps during monthly releases.


Release Process Checklist

1. Update Changelog for the Release

  • Branch: changelog (created off upstream/main)
  • Goal: Collect unreleased user-facing PRs into the release version header and set up a new ## Unreleased block.
  • Steps:
    1. Review commits merged since the previous release (git log <last-release-commit>..upstream/main).
    2. Identify missing user-facing PRs (bug fixes, new features, performance enhancements).
    3. In third_party/CHANGELOG.md, rename ## Unreleased to ## <new-version> (e.g. ## 508.0.0).
    4. Follow changelog formatting conventions:
      • Entries must strictly use descriptive, state-based phrases (typically starting with gerunds, nouns, or verbs like Avoid / Support / Log / Prevent) rather than starting with imperative verbs like Fix or Add.
      • Under ### Removed, do NOT repeat action verbs like "Remove" (e.g., - untilBuild restriction (#553)).
    5. Add a fresh empty ## Unreleased section at the top of third_party/CHANGELOG.md with standard subheaders (### Added, ### Changed, ### Removed, ### Fixed).
    6. Create PR (e.g. Update changelog for <version> (#<PR>)) and merge it to main.
    7. Delete local and remote changelog branch upon merge (git branch -D changelog).

2. Build & Validate

  • Compilation & Structure Verification:
    1. Ensure local main is checked out and updated (git fetch upstream && git checkout main && git reset --hard upstream/main), and navigate to the third_party directory (cd third_party).
    2. Run compilation check:
      ./gradlew testClasses
      
    3. Run plugin structure validation:
      ./gradlew verifyPluginStructure
      
    4. Run unit tests:
      ./gradlew test
      
  • Build Prospective Release Zip Artifact:
    1. Run the Gradle build with -PversionedName (from the third_party directory):
      ./gradlew buildPlugin -PversionedName
      
    2. Behavior:
      • Gradle reads the release version (<version>) directly from CHANGELOG.md.
      • The -PversionedName flag instructs build.gradle.kts to output Dart-<version>-<commitHash>.zip.
      • Generated zip location: third_party/build/distributions/Dart-<version>-<commitHash>.zip.

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.

It adds 18 tokens to every session and 1,016 once invoked, about $0.0001 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.
