tune-perl-ci

tune-perl-ci is a skill for Claude Code from oalders/kitchen-sink. It costs 78 tokens per session (6,545 once invoked), scanned B, original, MIT.

A maintenance skill for GitHub Actions workflows in Perl projects. It updates test versions, dependency installation, branch triggers, cancellation rules, and older operating-system test entries.

In plain words
What is it for?
Use it to modernize Perl CI workflows by extending the Perl matrix through 5.44, updating perl-tester images, configuring setup-cpm, limiting pushes to the default branch, and removing pre-5.24 macOS and Windows jobs.
Why use it?
Older CI settings can leave projects testing outdated Perl versions, running unnecessary jobs, or allowing stale runs to consume resources. The skill applies these workflow updates as separate reversible commits.

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 B, and why

tune-perl-ci scanned grade B with 1 finding 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 11d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- **Drop the old `sudo:` key.** No sudo is needed: `perldocker/perl-tester` containers run as root, and `shogo82148/actions-setup-perl` provisions a user-local Perl, so the install target is already writable.

Tune Perl CI

Overview

Seven transforms applied to Perl CI workflows under .github/workflows/:

  1. fail-fast: false on every matrix job
  2. Extend Linux + macOS matrices through Perl 5.44
  3. Bump build + coverage jobs to perldocker/perl-tester:5.44
  4. Restrict the push: trigger to the default branch
  5. Add a workflow-level concurrency: cancel-in-progress block
  6. Install deps with setup-cpm + a cpm install run step
  7. Drop macOS + Windows tests for Perls < 5.24

Core principle: modernize the workflow without changing intent. Each transform lands as its own commit so any single change is revertable. Re-running the skill on an already-tuned workflow is a no-op.

Dispatch this skill to a subagent

When this skill is invoked, dispatch the work to a general-purpose subagent via the Agent tool. Do not run the seven transforms inline in the caller's context.

Why:

  • Each transform reads every in-scope workflow, computes a diff, writes the file, runs yaml.safe_load + a structural assertion, then stages and commits. Across seven transforms and multiple workflows, that is a lot of Read/Edit/Bash tool traffic — none of it useful to the caller's session.
  • The caller only needs the final summary line (Applied N transforms across M files in K commits) and the list of commit SHAs. Everything else is intermediate state.

How to dispatch:

  • Brief the subagent with this SKILL.md as its working spec — pass the path to the file or invoke the skill from inside the subagent.
  • Tell the subagent the working directory and (optionally) a single workflow path if the caller specified one.
  • Require the subagent to report back, in under 200 words: the summary line, the per-transform commit SHAs, and any skipped transforms with reason.
  • If a transform's verification fails, the subagent must stop and surface the failure rather than continuing or auto-reverting.

If the user explicitly asks to run inline (e.g. "do it here so I can watch"), honour that — the subagent dispatch is the default, not a hard requirement.

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.

tune-perl-ci is a skill published in the GitHub repository oalders/kitchen-sink (4 stars, last pushed 11d ago), licensed MIT. It adds 78 tokens to every session and 6,545 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
