What it does

Maintainer Label System is an agent skill from InternationalColorConsortium/iccDEV. Maintain iccDEV repository labels, path labeler rules, issue triage labels, PR CI status labels, and label workflow governance.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Issue triage. It works with GitHub. The repository describes itself as: iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. The licence is BSD-3-Clause.

When your agent uses it

  • Tasks that involve Issue triage

Example prompts

  • “/maintainer-label-system”

Requirements

  • Docker
  • Pre-approved tools (allowed-tools): bash, read, grep, glob, shell(git:*)

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. The branch or PR being changed.
  2. Whether the change is taxonomy-only, path-label automation, issue triage,
  3. Any labels that must remain stable for existing issues, PRs, or workflows.

What it can do on your machine

Read from SKILL.md and the folder at commit 3c2425d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • bash
    • read
    • grep
    • glob
    • shell(git:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • bash
    • actionlint
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Maintainer Label System loads about 1k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 391 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Maintainer Label System

Use this skill when adding, removing, or auditing labels and label automation.

Required Inputs

  1. The branch or PR being changed.
  2. Whether the change is taxonomy-only, path-label automation, issue triage, PR status labeling, or CodeQL label routing.
  3. Any labels that must remain stable for existing issues, PRs, or workflows.

Workflow

  1. Read ../../../docs/label-system.md.
  2. Audit the managed manifest against live labels before changing taxonomy. .github/labels.yml is not destructive: classify undeclared live labels as legacy or migrate them deliberately.
  3. Update .github/labels.yml before changing workflow or labeler behavior.
  4. Add .github/labeler.yml rules only for deterministic file paths or branch names. Do not classify severity, exploitability, or maintainer judgment from PR text.
  5. Keep privileged label workflows on trusted metadata:
    • no checkout of PR head code in pull_request_target;
    • explicit zizmor rationale for any retained pull_request_target labeler;
    • least-privilege job permissions;
    • pinned third-party actions;
    • no direct ${{ }} expressions inside shell.
  6. Keep issue triage and PR-status labeling independent of taxonomy synchronization; neither may issue manifest-wide label writes for every issue or PR event.
  7. If issue triage logic changes, keep it conservative and make labels easy for maintainers to override.
  8. If PR status labels change, preserve mutual exclusion among passed, failed, and pending.
  9. If PR CI control labels change, keep them maintainer-only, one-shot, and restricted to same-repository pull requests.
  10. Update docs, prompts, agents, and the inventory artifact when policy or maintainer workflow changes.
  11. For a new scope label, add its canonical .github/labels.yml entry before issue-text or path automation. Keep deletion manual after checking all active label consumers.

Review Checklist

  • .github/labels.yml contains every automated label.
  • Managed labels are reconciled with the live inventory without deleting legacy labels or rewriting unchanged metadata.
  • .github/labeler.yml paths are specific enough to avoid noisy labels.
  • Large PR safeguards still exist.
  • Label workflows do not execute untrusted PR content.
  • Status labels remain machine-managed and mutually exclusive.
  • PR CI control labels are documented, canonical in .github/labels.yml, and unavailable to fork PR fast lanes.
  • bump-sha-pins is documented as a maintainer follow-up label for pinned GitHub Action, Docker, or container SHA refreshes.
  • codeql-ready still routes to the full CodeQL workflow.
  • Documentation, skills, and prompts point to the same canonical files.
  • The label-triage agent and inventory artifact match the managed manifest.
