Examples

/code-review ultra

Effects and persistence

Runs a deep review in a cloud sandbox. Usage credits are required after included free runs are exhausted.

Recovering after an error

/goal now retries with backoff or pauses with an explanation after API errors, network loss, and token/usage limits, including waiting for a usage reset. Verify both goal status and outputs before treating the work as complete.

Effort selection

maxEffortLevel caps effort globally or per model under modelSettings, including Bedrock, Vertex, and Foundry. Users may choose a lower effort. Inspect the effective cap when /effort cannot reach the expected level.

Key takeaways

  • Groups the operational commands: permission and sandbox controls, MCP and plugin management, project cleanup, and a troubleshooting sequence.
  • Scope /permissions rules by tool and path, and treat /sandbox as one layer rather than the sole security boundary.
  • claude project purge deletes transcripts, task lists, logs, and the project entry in ~/.claude.json; always run --dry-run first.
  • claude --safe-mode disables customizations (CLAUDE.md, hooks, plugins, MCP, skills) to isolate what triggers a Fable-to-Opus fallback, while keeping auth and permissions active. The automatic fallback follows the safety classifiers that shipped with the 2026-07-01 Fable 5 redeployment and carry over to Fable 5.1; biology flags rerun on Opus 5 and cybersecurity flags on Opus 4.8.
  • CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 bundles the autoupdater, feedback, error-reporting, and telemetry disables for locked-down environments.
  • v2.1.248 adds --restricted/CLAUDE_CODE_RESTRICTED=1; v2.1.248–251 also harden symlink and path traversal across file tools, plugin commands, workflow scriptPath, and Grep/Glob deny rules.

Cautions

Check the comparison target and credit usage. A whole-repository fallback can require explicit consent.
