Refactor

Use this Skill to produce a bounded, verifiable Refactor outcome. Preserve the user's chosen stack, source material, and authorization boundaries.

Read the SandBase API map only when the task genuinely needs an external data source or generative model.

Workflow

1. Inspect the available files, runtime, versions, inputs, and existing conventions before deciding what to change.
2. Restate the requested outcome, constraints, acceptance checks, and any assumption that could change the result.
3. Produce the smallest complete implementation, analysis, or artifact that satisfies those checks.
4. Verify the real output with appropriate tests, previews, calculations, or source comparison; do not infer success from file creation alone.
5. Return the deliverable, evidence of validation, material assumptions, and unresolved limitations.

Quality gates

• Inspect repository instructions, current versions, tests, and user changes before proposing an implementation.
• Make the smallest compatible change, preserve public contracts unless change is requested, and avoid new dependencies without a concrete benefit.
• Run focused tests plus the relevant build or static checks, then report observed results and any unverified paths.

Focus checks

• Capture behavior with focused tests, make one structural change at a time, preserve interfaces and outputs, and keep performance or readability claims tied to evidence.

SandBase boundary

Keep the core Refactor work local. Use SandBase only for current external documentation, repository evidence, or explicitly requested model inference.

1. Call sandbase_discover with a short capability query.
2. Call sandbase_inspect for viable candidates and compare the live schema, coverage, limits, output, execution mode, and price.
3. Prefer a dedicated tool or API the user already has. Send only the minimum necessary data.
4. Before any paid call, show the endpoint, important arguments, current unit price, call count, and total estimate or uncertainty, then obtain confirmation.
5. Use sandbase_account before an approved multi-call batch and call sandbase_run only with current schema-defined arguments.
6. Poll asynchronous work with sandbase_run_get using the same run ID; never resubmit merely because it is pending.
7. Use sandbase_runs only to recover status or reconcile observed cost.

If SandBase is unavailable, continue with local work and authorized sources when possible. Do not silently switch providers, fabricate external results, or claim a generation or retrieval succeeded.

Handoff

Provide the completed artifact or findings, concise reproduction steps, checks actually run, source or asset provenance, SandBase endpoint and run IDs when used, observed cost when available, and any follow-up that still requires user action.
