What it does
CI Triage is an agent skill from fair-acc/gnuradio4. Fetch and classify a failed GitHub Actions job for this repo — distinguish out-of-memory kills, six-hour timeouts, configure errors and genuine test failures, and identify what was in flight. Use whenever a CI job fails.
Its SKILL.md is about 550 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 DevOps & Cloud, covering Failing and flaky tests and CI/CD. It works with GitHub Actions. The repository describes itself as: Prototype implementations for a more compile-time efficient flowgraph API. The licence is LGPL-3.0.
When your agent uses it

- Tasks that involve CI/CD
Example prompts
- “/ci-triage”
What it can do on your machine
Read from SKILL.md and the folder at commit af62235. 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
Shell commands in SKILL.md call:
ghcmake
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh, 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
CI Triage loads about 548 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 179 words of instructions outside code blocks.
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 triage
Fetching logs
gh run view --log refuses while the run is still in progress. This always works:
JID=$(gh run view <run-id> --json jobs -q '.jobs[]|select(.name=="<job>")|.databaseId')
gh api --allow-escape-sequences "repos/fair-acc/gnuradio4/actions/jobs/$JID/logs" \
| sed 's/\x1b\[[0-9;]*[a-zA-Z]//g' > job.logWithout --allow-escape-sequences the call fails; without the sed the log is unreadable.
Classification
| signature | cause |
|---|---|
exit code 137 + "runner has received a shutdown signal" | OOM — the kernel killed the runner |
Build step with no conclusion at all | OOM so hard the step never reported |
conclusion cancelled at ~360 min | six-hour job timeout |
CMake Error: generator : Ninja / Does not match ... Unix Makefiles | a cached _deps sub-build from another generator |
***Failed <n> sec | the test's own bound, not a ctest timeout |
***Timeout | ctest TIMEOUT property |
After an OOM
The runner is 4 cores / ~16 GB. Read the last twenty lines: the compiles and links in flight are the
peak. Sum their measured peak RSS (see the measure-build-cost skill) before changing
GR_BUILD_PARALLEL_LEVEL — a job count sized from core count rather than memory is how this repo
OOMs.
Also grep cores, for the runner's own report of cores and MemTotal, and Hits: for the ccache hit
rate, which explains most duration differences between runs.

When should I use CI Triage?
CI Triage fits situations like: tasks that involve Failing and flaky tests; tasks that involve CI/CD.
How do I install CI Triage in Claude Code?
Run `npx skills add fair-acc/gnuradio4 --skill ci-triage -a claude-code`. Or copy the skill folder (.claude/skills/ci-triage in fair-acc/gnuradio4) into .claude/skills/ci-triage in your project. Claude Code loads it when a task matches its description.
How do I install CI Triage in Codex?
