Troubleshooting

Most problems fall into one of three buckets: daemon not running, agent not found, or push not triggering the pipeline. This page walks each one.

First stop for anything: no-mistakes doctor.

Debug in this order

flowchart TD
  problem["Something is wrong"] --> doctor["Run no-mistakes doctor"]
  doctor --> daemon{"Daemon issue?"}
  daemon -- "yes" --> daemonpath["Check daemon status and daemon.log"]
  daemon -- "no" --> triggered{"Did the push trigger a run?"}
  triggered -- "no" --> gate["Check remote, hook, and socket"]
  triggered -- "yes" --> provider["Check agent or provider setup"]

That order matches the actual boundaries in the system:

  • local environment and binaries
  • daemon and gate wiring
  • provider-specific PR or CI integration

Daemon won’t start

Symptoms: no-mistakes daemon status shows stopped, or no-mistakes exits with “daemon not running.”

Start it manually

Terminal window
no-mistakes daemon start

This installs or refreshes the managed service (launchd, systemd user service, or Task Scheduler), then starts it. If service install or startup fails, it falls back to a detached daemon.

Check logs

Terminal window
tail -f ~/.no-mistakes/logs/daemon.log

Check for stale artifacts

Stale PID files or sockets from a crashed daemon can block startup:

Terminal window
ls -la ~/.no-mistakes/daemon.pid ~/.no-mistakes/socket

If the PID file points at a process that’s no longer running, remove both and run no-mistakes daemon start again.

Managed service logs

  • macOS (launchd): launchctl list | grep no-mistakes and check ~/Library/LaunchAgents/com.kunchenguid.no-mistakes.daemon.*.plist
  • Linux (systemd): systemctl --user status no-mistakes-daemon-* and journalctl --user -u no-mistakes-daemon-* -f
  • Windows (Task Scheduler): schtasks /query /tn "no-mistakes-daemon-*"

NM_HOME collisions

If you have multiple installs with different NM_HOME roots, each gets its own scoped service name (with a short suffix derived from the path). Make sure you’re looking at the right one - no-mistakes daemon status reports which.

no-mistakes update prompts or aborts

Symptom: update warns about active pipeline runs, says the daemon is running from a different executable path, or aborts because the daemon executable path cannot be determined.

When pending or running pipeline runs exist, update warns that restarting the daemon can cause those runs to fail and prompts before continuing. When the running daemon uses a different binary, update prompts before replacing it. Pass no-mistakes update -y to confirm non-interactively while still printing warnings.

If the daemon executable path can’t be determined at all (stale PID, permissions), the update aborts before replacing anything.

Fix:

Terminal window
no-mistakes daemon stop
no-mistakes update

Agent binary not detected

Symptom: doctor shows for your native agent, or the pipeline errors with “agent binary not found.”

Check PATH

The daemon uses the same binary-discovery order described in Choosing an Agent. When it’s running through a managed service, it reloads PATH from your login shell on macOS and Linux and appends common install locations such as ~/.local/bin, ~/go/bin, ~/.cargo/bin, ~/bin, /opt/homebrew/bin, /usr/local/bin, /usr/bin, and /bin.

If a native agent is installed in a version-manager shim directory or another nonstandard location, set an explicit override in ~/.no-mistakes/config.yaml:

agent_path_override:
claude: /Users/you/.local/bin/claude

For agent: acp:<target>, set acpx_path instead:

acpx_path: /Users/you/.local/bin/acpx

The daemon logs its effective PATH at startup in ~/.no-mistakes/logs/daemon.log with the message daemon environment ready. If the log contains login shell environment resolution failed or login shell environment resolution returned no entries, the daemon used a degraded fallback PATH that may omit version-manager directories such as nvm, fnm, or volta, so tools like pnpm may be missing.

Restart the daemon after installing a new agent

Terminal window
no-mistakes daemon stop
no-mistakes daemon start

macOS App Management prompts during agent runs

Pipeline prompts steer agents to keep intentional writes inside the disposable worktree and avoid mutating system locations such as /Applications, Homebrew-managed packages, or global tool configuration. This reduces macOS App Management prompts from agent-invoked commands, but it is not an OS sandbox.

If you still see prompts, check the step log for commands that intentionally write outside the worktree and move that setup into your normal development environment or an explicit repo-local command. Requested test evidence may still be written under the managed temporary no-mistakes-evidence directory, or under the configured in-repo evidence directory when test.evidence.store_in_repo is enabled. Normal tool temp or cache writes can still happen outside the worktree. Testing prompts ask agents to remove transient working-tree artifacts they created, such as downloaded models, caches, build outputs, large binaries, or generated data directories, before completion.

A pipeline step failed

Symptom: a run stops with a failed step.

Check the per-step log at ~/.no-mistakes/logs/<runID>/<step>.log. Fatal step errors are appended to that log, so failures such as rejected pushes include the returned error output there instead of only appearing in daemon.log.

git push no-mistakes doesn’t start a pipeline

Symptom: push succeeds but no-mistakes shows no active run.

Check the remote

Terminal window
git remote -v | grep no-mistakes

If it’s missing, run no-mistakes init again. Re-running init refreshes an existing gate and repairs the no-mistakes remote when it is missing. It also reattaches an existing gate after you rename or move the repo directory, as long as the old path no longer exists.

Check the hook

The gate’s bare repo has a post-receive hook that notifies the daemon. Look at the gate path:

Terminal window
no-mistakes status
# gate path is shown in the output
ls -la <gate-path>/hooks/post-receive

The hook should be executable. If it’s missing or non-executable, no-mistakes init will reinstall it for an existing no-mistakes-managed gate. For existing gate repos, no-mistakes daemon restart also installs missing no-mistakes-managed hooks and refreshes legacy managed hooks without overwriting custom hooks.

Also check <gate-path>/notify-push.log. The hook now appends daemon notification failures there and prints the same error back to the pushing client.

Check the daemon socket

The hook talks to the daemon over ~/.no-mistakes/socket. If the daemon isn’t running, the push still succeeds (the hook never blocks), but no pipeline starts. Start the daemon and push again.

If the gate is older, re-running no-mistakes init or restarting the daemon also reapplies hook-path isolation for existing bare repos when Git supports config --worktree. That protects the gate hook if a tool such as Husky wrote core.hookspath into shared git config from inside a linked worktree.

PR step is skipped

Symptom: pipeline completes but the PR step shows skipped.

Check the Provider Integration requirements. Most common causes:

  • gh or glab not installed
  • gh auth status shows not authenticated
  • Bitbucket env vars not set in the daemon’s environment
  • Upstream is on a host that isn’t supported (GitHub, GitLab, or bitbucket.org)
  • You pushed the default branch (PR step always skips on the default branch)

CI step stuck or timed out

Symptom: CI step runs for 4 hours and pauses for approval.

ci_timeout defaults to 4h. Raise it in ~/.no-mistakes/config.yaml:

ci_timeout: "8h"

The CI step keeps monitoring while the PR remains open, even after checks are currently healthy, because a later default-branch update can make the PR conflict or rerun CI. Once checks are green and the PR is mergeable, the CI panel shows ✓ Checks passed and the terminal title switches to Checks passed, so you can tell when to go merge the PR. The signal clears automatically if checks start re-running or a new failure appears. If the PR is still open at the timeout, the step pauses for approval with findings for the open monitoring state or any known unresolved failures. You can approve (accept the risk), fix (run another auto-fix cycle), skip, or abort from the TUI or no-mistakes axi respond.

Worktree won’t clean up

Symptom: ~/.no-mistakes/worktrees/<repoID>/<runID>/ sticks around after a run ends.

The daemon removes worktrees at run completion, and also on daemon startup (crash recovery). If one is still there:

Terminal window
# From inside the repo the worktree belongs to:
git worktree list
git worktree remove --force <path>

Or let the daemon clean it on next startup:

Terminal window
no-mistakes daemon stop
no-mistakes daemon start

Reset everything

When state is genuinely wedged:

Terminal window
no-mistakes daemon stop
rm -rf ~/.no-mistakes/worktrees ~/.no-mistakes/servers ~/.no-mistakes/socket ~/.no-mistakes/daemon.pid
no-mistakes daemon start

This keeps your gate repos, database, and config but clears transient state. For a full wipe, see the Uninstall section.

Still stuck
