What it does

Oncall is an agent skill from pigweed-project/pigweed. Pigweed oncall rotation runbooks and maintenance workflows (such as rolling CIPD client tools for b/315378787). DO NOT auto-load during normal coding tasks. Only load when explicitly triggered by the user via the /oncall or /roll-cipd slash command.

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts (for example `TEST.md`, `resources/roll_cipd.md` and `scripts/roll_cipd.py`).

It sits in DevOps & Cloud, covering Incident response, Hooks and plugins and Runbooks and postmortems. The repository describes itself as: Modern software development for embedded systems. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Incident response
  • Tasks that involve Hooks and plugins
  • Tasks that involve Runbooks and postmortems

Example prompts

  • “/oncall”

Requirements

  • Python 3

Workflow steps

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

  1. Determine candidate git_revision tags
  2. Roll version and update digests
  3. Check and verify
  4. Verify client functionality
  5. Commit changes
  6. Submit to Gerrit

What it can do on your machine

Read from SKILL.md and the folder at commit de25dbe. 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 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • git
    • gh

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

  • Network

    Links to these hosts (documentation or services it may open):

    • pwbug.dev

    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

Oncall loads about 992 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 285 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~992

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); the scripts in this folder are not scanned.

description
Pigweed oncall rotation runbooks and maintenance workflows (such as rolling CIPD client tools for b/315378787). DO NOT auto-load during normal coding tasks. Only load when explicitly triggered by the user via the `/oncall` or `/roll-cipd` slash command.

Pigweed Oncall Workflows

This skill provides operational workflows and runbooks for the Pigweed oncall rotation. It is designed to be manually triggered via slash commands to prevent unnecessary auto-loading.


Invoking this Skill

Trigger this skill and its subskills explicitly using slash commands in the prompt:

  • /oncall: Access the general oncall workflow, overview, and task router.
  • /oncall roll-cipd or /roll-cipd: Trigger the CIPD client update subskill (b/315378787), which rolls the pin, creates a pw_env_setup: Roll cipd commit, and submits it.
  • /oncall presubmit: Run presubmit verification on your branch or stack.

Oncall Responsibilities & Subskills

Subskill / CommandDescriptionRunbook / Tool
/roll-cipdUpdate pinned CIPD version, create pw_env_setup: Roll cipd commit, and submit to Gerrit (b/315378787)roll_cipd.md / roll_cipd.py
/oncall presubmitRun presubmit checks across commit stacksRun Presubmit Checks
/oncall reviewReview incoming and ongoing Git/Gerrit patchesCode Review

Subskill: Roll CIPD Client (b/315378787)

CIPD (Chrome Infra Package Deployer) is used by Pigweed to install and manage prebuilt toolchains and binaries. Updating the CIPD client pin is a recurring oncall maintenance task tracked under b/315378787.

Triggers
  • Explicit user slash commands: /roll-cipd or /oncall roll-cipd.
  • Explicit user prompt during oncall rotation specifically requesting CIPD pin roll.
Guards
  • Do not auto-load on general tool, environment, or setup tasks unless explicitly requested.
  • Do not use the mutable latest ref in .cipd_version (it causes selfupdate validation failures).
  • Always ensure all platform digests in .cipd_version.digests are generated and verified.
Execution Workflow

Run the oncall helper script:

bash
# Roll and commit
python3 .agents/skills/oncall/scripts/roll_cipd.py --commit

# Roll, commit, and submit to Gerrit
python3 .agents/skills/oncall/scripts/roll_cipd.py --commit --push
Option 2: Manual Roll, Commit & Push
  1. Determine candidate git_revision tags:
    bash
    python3 pw_env_setup/py/pw_env_setup/cipd_setup/wrapper.py describe \
        infra/tools/cipd/linux-amd64 -version latest
  2. Roll version and update digests:
    bash
    python3 pw_env_setup/py/pw_env_setup/cipd_setup/wrapper.py selfupdate-roll \
        -version-file pw_env_setup/py/pw_env_setup/cipd_setup/.cipd_version \
        -version git_revision:<HASH>
  3. Check and verify:
    bash
    python3 pw_env_setup/py/pw_env_setup/cipd_setup/wrapper.py selfupdate-roll \
        -version-file pw_env_setup/py/pw_env_setup/cipd_setup/.cipd_version \
        -check
  4. Verify client functionality:
    bash
    python3 pw_env_setup/py/pw_env_setup/cipd_setup/wrapper.py -version
  5. Commit changes:
    bash
    git add pw_env_setup/py/pw_env_setup/cipd_setup/.cipd_version \
        pw_env_setup/py/pw_env_setup/cipd_setup/.cipd_version.digests
    git commit -m "$(cat <<'EOF'
    pw_env_setup: Roll cipd

Rolls CIPD client version to <git_revision>.

Bug: 315378787 EOF )"

6. Submit to Gerrit:
```bash
./gh pr create --cq
