Always fetch the CI result JSON before reading code or proposing fixes.

Determining PR, sha, and workflow name

From a Praktika report URL (e.g. https://silk-artifacts-eu-north-1.s3.amazonaws.com/json.html?PR=12&sha=abc123&name_0=PR):

Extract PR, sha, name_0 from query params
Normalize name_0: lowercase + spaces → underscores (e.g. "PR" → "pr")

From a bare PR number:

Run gh pr view {PR} --json headRefOid --jq '.headRefOid' to get the latest sha
Use pr as the normalized workflow name

Building the JSON URL

https://silk-artifacts-eu-north-1.s3.amazonaws.com/PRs/{PR}/{sha}/{normalized}/result_{normalized}.json

Fetch this URL with WebFetch.

Result structure

The JSON is a serialized praktika.Result:

{
  "name": str,
  "status": str,       # OK | FAIL | ERROR | SKIPPED | UNKNOWN | XFAIL | XPASS | PENDING | RUNNING | DROPPED
  "start_time": float?,
  "duration": float?,
  "info": str,
  "results": [...],    # nested Result objects, same shape, recursive
  "files": [...],
  "links": [...],
  "ext": {
    "labels": [{"name": str, "link": str?, "hint": str?}, ...],
    "warnings": [...],
    "errors": [...],
    "report_url": str?,
    ...
  }
}

Walk the results tree recursively to find all failing jobs and sub-jobs. Use the info field of failing nodes as the primary signal for what went wrong before touching any code.

The nested results of the main workflow result are the individual job results. Each job result is expected to include a link to its job.log (in links). When a failing job's info doesn't contain enough detail to pinpoint the problem, job.log can be used to dig into the full output.

How to use it

Copy the folder

Take clickhouse/check-ci from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
