Babysitter is a workflow engine for AI coding agents that enforces predefined steps, quality checks, human approvals, and decision records. It is used to coordinate complex, repeatable agent workflows across supported coding tools. The catalogue contains skills, agents, instructions, settings, a plugin, and an MCP integration for its workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00230 |
| Opus 5 | $0.00013 | $0.00115 |
| Sonnet 5 | $0.00005 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
executing-plans scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
- Executing in a separate/parallel session
- Want human checkpoints between task batches
Process
- Load persisted tasks (resume support)
- Verify/setup worktree
- Execute tasks in batches (default 3)
- Report after each batch, wait for feedback
- Finish branch after all tasks complete
Agents Used

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

executing-plans is a skill published in the GitHub repository a5c-ai/babysitter (1,778 stars, last pushed 4d ago), licensed MIT. It adds 25 tokens to every session and 230 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
Other skills, from other repositories
version-bump
Version the Team plugin at land time (DEV-internal, not distributed): decide the SemVer level, compute the next free version against current main, update all six version strings, cut the [Unreleased] changelog body into a dated [X.Y.Z] section, run the land-time consistency assertion, and commit chore(version): X.Y.Z.…
qrspi-workflow
Defines QRSPI phases, artifacts, gates, and state transitions. Load when routing or resuming Team pipeline work.
tracking-tickets
Defines tracker status transitions and closing rules. Load when a pipeline run is linked to a ticket.
team-pr
Opens a pull request after verification. Trigger on "open the PR", "open a draft PR", or "/team-pr" only; never infer the phase from passed verification.
pr-watch-mechanics
Bounded watch-loop mechanics for the pr-watch skills: cycle timing, soft cap, handoff. Load when running or authoring a PR watch loop.
pr-screenshots
Attaches local images to a PR body. Invoke ONLY on explicit intent: "add screenshots to a PR", "attach an image to a PR description", or "/pr-screenshots"; never infer it from images on disk.
