What it does

CI Timing is an agent skill from wado-lang/wado. Measure how long GitHub Actions jobs and steps took across past runs, and find the pull request that made CI slower. Use for any question about CI duration, a slow job, or when CI got slow.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Development, covering Pull requests and CI/CD. It works with GitHub Actions and WebAssembly. The repository describes itself as: The Wado Programming Language. The licence is MIT.

When your agent uses it

  • Any question about CI duration
  • Tasks that involve Pull requests
  • Tasks that involve CI/CD

Example prompts

  • “/ci-timing”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 037dba4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • mise

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

  • Network

    No URLs in SKILL.md.

    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

CI Timing loads about 518 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 270 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~518

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.

CI Timing

ci-times.mjs reads run, job and step timings from the GitHub API with gh. Run it with mise's Node, and redirect its output to a file in scratchpad/: a sweep over a month makes hundreds of API calls.

Find When a Job Got Slower

Sweep the runs on main, one row per run, oldest first:

sh
mise exec -- node .claude/skills/ci-timing/ci-times.mjs \
  --since 2026-09-01 --job 'E2E\+stdlib' --step stdlib \
  > scratchpad/ci-times.tsv

Each matched job prints as name=STEP/JOB in seconds. - means the step did not run or there was no --step. The row ends with the run's title, which names the merged pull request. Look for the row where a job's total steps up and stays up.

Only runs on main from push events give a clean timeline: each one is a single merge. The defaults are --workflow ci.yml --branch main --event push.

Find Which Step Grew

The job total can grow while the step you guessed stays flat. A step that a pull request added is invisible to --step. Print every step of the runs on either side of the jump and compare them:

sh
mise exec -- node .claude/skills/ci-timing/ci-times.mjs --sha <before> --job 'stdlib O3'
mise exec -- node .claude/skills/ci-timing/ci-times.mjs --sha <after>  --job 'stdlib O3'

--run <run id> does the same for a run that is not on main, such as a pull request's run.

Read the Numbers

  • Hosted runners vary from run to run. Several runs on each side of a jump show a real change. A single run does not.
  • The slowest job sets how long CI takes. A step that grew in a job that finishes early does not slow CI down.
  • A test step grows as tests are added. Compare its growth with the growth in the count of what it runs (wado-compiler/tests/fixtures/*.wado, test blocks under wado-compiler/lib/) before calling it a regression.
