Overview

Use this skill for deterministic local automation tasks handled by shell commands or small helper scripts.

Use Pseudo-Agentic Automation only when browser/GUI interaction is required.

Scope Boundary

Use this skill when command execution needs explicit deterministic workflow structure, retry policy, and validation contract.

Do not invoke for one-off trivial commands that do not require orchestration.

Preconditions

Before execution:

1. define desired end state
2. verify working directory and permissions
3. identify potential side effects
4. identify rollback/recovery approach for risky operations
5. derive proportional validation from the requested outcome and repository evidence; ask only when a material missing choice changes the result
6. operate locally by default; do not deploy unless explicitly requested
7. for expensive verification commands, probe runtime dependencies first (for example browsers, shared libraries, required binaries)

Use This Skill When

• Setting up environments and dependencies.
• Running local service orchestration flows.
• Performing repeatable batch operations.
• Executing command pipelines with clear expected outputs.

Do Not Use This Skill When

• Browser-based login/CAPTCHA flows are required.
• Dynamic web interaction is core to task success.
• Native GUI automation is required.

Workflow

1. Derive and confirm the desired end state from the active task contract.
2. Check current state first (pwd, ls, status commands).
3. Execute minimal command sequence.
4. Validate results explicitly.
5. If commands fail, inspect stderr, adjust, and retry with bounded attempts.

Retry policy:

1. default retry limit: 3
2. if repeated failures suggest missing prerequisites, pause and resolve prerequisites first
3. if failure risk escalates (data loss/security), stop and escalate

Command Rules

1. Prefer idempotent commands.
2. Scope side effects to the project directory.
3. Use non-interactive flags by default.
4. Avoid destructive operations unless explicitly requested.
5. Capture key outputs for verification.
6. Do not run deployment/publish/release commands unless user explicitly asks.

Script Guidance

1. Use short scripts only when command chains become complex.
2. Emit machine-readable result artifacts only when the task authorizes them and they are required for a consumer or evidence contract.
3. Print diagnostics to stderr.
4. Exit non-zero on failure paths.

Validation Checklist

1. Confirm expected files/directories/services are present.
2. Confirm outputs match requested outcomes.
3. Confirm sensitive data was not staged or exported.
4. Report exact commands and results.
5. If a command is blocked by environment constraints, capture exact blocker error and switch to constrained verification fallback rather than blind retries.

Deliverable Format

When applying this skill, provide:

1. end-state target
2. commands executed
3. validation results
4. unresolved issues or residual risk
