ca-task
The sanctioned task-board mutator — add a queued task, start one (flips to in-progress and stamps the date, minting a dotted ID on pick-up), or mark an in-progress task done. The only blessed write to open-tasks.md.
npx skills add arbiterForge/codeArbiter --skill ca-task --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# $ca-task — task-board writer The one blessed way to mutate `<project-root>/.codearbiter/open-tasks.md` (resolves D-1). Hand-editing the board is no longer the only path; this command keeps every entry schema-conformant and every transition dated. The board LOGIC lives in the pure `_taskboardlib` transforms; this command runs the thin writer `${CLAUDE_PLUGIN_ROOT}/hooks/taskwrite.py`. ## Verbs Always put `--` before user text (a desc or title) so a value beginning with `-` is not parsed as a flag. Resolve the interpreter once by presence — `PY=python3; { command -v python3 >/dev/null 2>&1 && python3 --version >/dev/null 2>&1; } || PY=python` — never `python3 … || python …`, which reruns the helper on any nonzero exit and reports the second run's code instead of the first's (#577) — then invoke `"$PY"` below. - **add** — append a queued task. ID-less by default; pass `--id <group>.<type>` to mint a dotted ID now, `--from <origin>` for a harvest back-ref, `--boundaries a,b` for the security/trust boundaries it touches. The description must be nonblank and single-line; origin and boundary values must also stay on one line. - `"$PY" "${CLAUDE_PLUGIN_ROOT}/hooks/taskwrite.py" add [--id

What does the ca-task skill do?
The sanctioned task-board mutator — add a queued task, start one (flips to in-progress and stamps the date, minting a dotted ID on pick-up), or mark an in-progress task done. The only blessed write to open-tasks.md.
How do I install it?
Run `npx skills add arbiterForge/codeArbiter --skill ca-task --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From arbiterForge/codeArbiter, a repository with 138 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
