paseo-loop

getpaseo/paseo

Run an agent loop with worker/verifier cycles until an exit condition is met.

What is paseo-loop?

Paseo Loop executes iterative autonomous workflows by launching a worker agent, verifying progress, and repeating until done or limits are hit. Use when you need continuous execution, polling, babysitting, or "keep trying until" behavior.

  • Execute worker/verifier cycles: launch worker → check verification → repeat until exit condition
  • Support multiple verification shapes: shell checks (objective criteria), verifier prompts (judgment-based), or both
  • Manage loop lifecycle with CLI commands: ls, inspect, logs, stop, and run
  • Configure worker and verifier providers independently, optionally from orchestration preferences
  • Set iteration and time limits to prevent runaway loops
  • Archive agent states after each iteration for inspection and debugging

How to install paseo-loop

npx skills add https://github.com/getpaseo/paseo --skill paseo-loop
Prerequisites
  • Paseo skill must be installed and readable
  • Orchestration preferences file at ~/.paseo/orchestration-preferences.json (unless providers explicitly named)
  • Clear understanding of worker intent and verification criteria before launching

How to use paseo-loop

  1. 1.Define the worker prompt: self-contained, concrete, explicit about what counts as progress
  2. 2.Choose verification shape: shell check (objective), verifier prompt (judgment), or both
  3. 3.Select worker and verifier providers from preferences or explicitly name them
  4. 4.Set --max-iterations and/or --max-time to prevent runaway loops
  5. 5.Add --sleep only when polling external systems; otherwise let it run fast
  6. 6.Optionally use --archive to keep agent states for inspection after each iteration
  7. 7.Launch with: paseo loop run

Use cases

Good for
  • Babysit a pull request: worker fixes issues, shell check validates PR status, sleeps 2m between checks, max 1h runtime
  • Drive tests to green: worker investigates test failures and fixes code, verifier confirms all tests pass, max 10 iterations
  • Cross-provider implementation: worker on one provider, verifier on another to catch each other's blind spots, bounded iterations and time
  • Poll external systems: worker checks state of external service, sleeps between checks, repeats until condition met
  • Autonomous code improvement: worker refactors or optimizes code, verifier checks quality metrics and test results
Who it's for
  • Developers automating repetitive fix-and-verify workflows
  • DevOps engineers babysitting deployments or infrastructure checks
  • QA automation specialists driving test suites to completion
  • Anyone needing iterative autonomous execution with verification

paseo-loop FAQ

When should I use a shell check vs. a verifier prompt?

Use shell check (--verify-check) for objective criteria a command can answer, like test results or PR status. Use verifier prompt (--verify) for judgment calls that need reasoning. Use both when shell rules out obvious failures and the verifier judges the rest.

Should worker and verifier use the same provider?

For implementation loops, pair them on different providers—each catches the other's blind spots. For simpler loops, the same provider is fine.

What are sensible defaults for max-iterations and max-time?

Depends on the task. Babysitting a PR might be max-time 1h with 2m sleep. Driving tests to green might be max-iterations 10. Always set both to prevent runaway loops.

Can I inspect a running or completed loop?

Yes. Use `paseo loop ls` to list loops, `paseo loop inspect <id>` to see details, `paseo loop logs <id>` for output, and `paseo loop stop <id>` to stop it.

What does --archive do?

--archive keeps agent states after each iteration so you can inspect what the worker and verifier did, helping debug loops or understand decision-making.

Paseo Loop Skill

A loop is a worker/verifier cycle: launch a worker → check verification → repeat until done or limits hit. Use for "keep trying", "babysit", or "watch this until X."

User's arguments: $ARGUMENTS

Prerequisites

Read the paseo skill. Before choosing worker or verifier providers, read ~/.paseo/orchestration-preferences.json unless the user explicitly named providers in this request. Do not start the loop until you have read it.

Loops are a CLI primitive: paseo loop run. Manage with paseo loop ls, paseo loop inspect <id>, paseo loop logs <id>, paseo loop stop <id>.

Your job

  1. Understand the user's intent from $ARGUMENTS and the conversation.
  2. Worker prompt — self-contained, concrete about what to do this iteration, explicit about what counts as progress.
  3. Verification — pick the right shape:
    • Shell check (--verify-check) for objective criteria a command can answer (gh pr checks --fail-fast, npm test).
    • Verifier prompt (--verify) for judgment ("Return done=true only if all tests pass and the changed files are coherent. Cite the command and the outcome.").
    • Both, when shell rules out the obvious failures and the verifier judges the rest.
  4. Providers--provider for the worker, --verify-provider for the verifier. From preferences unless the user named them. For implementation loops, pair worker and verifier on different providers — each catches the other's blind spots.
  5. Sleep--sleep only when polling something external. Otherwise let it run as fast as the loop completes.
  6. Stops — set a sensible --max-iterations and/or --max-time. Open-ended loops are how runaways happen.
  7. Archive--archive keeps agents after each iteration for inspection.
  8. Launch with paseo loop run.

Common shapes

Babysit a PR — worker checks PR state and fixes issues; shell check is gh pr checks <n> --fail-fast; sleep 2m; max-time 1h.

Drive tests to green — worker investigates failures and fixes code; shell check is the test command; verifier confirms all tests pass; max-iterations 10.

Cross-provider implementation — worker on impl provider, verifier on a different provider; verifier checks changed files, runs typecheck and tests; max-iterations and max-time both bounded; archive on so iterations can be inspected.

Prompt rules

Worker — self-contained, concrete (commands, files, branches, tests, PRs, systems), explicit about what counts as progress this iteration.

Verifier — checks facts, doesn't suggest fixes, cites commands/outputs/file evidence, specific about what "done" means.
