Plugin Router

Internal helper for Plugin Factory follow-up routing. The canonical front door is [[plugin-factory-router]]; use this skill only after that router selects a router follow-up or when a loaded Plugin Factory workflow explicitly asks for the detailed route map.

Philosophy

• Route first, execute second.
• Prefer one clarification over unsafe guessing when ambiguity changes risk.

When to Use

Use when plugin intent remains broad, mixed, or missing a clear lane owner after canonical Plugin Factory routing.

Do not use this as the root Plugin Factory entrypoint. Route root-level plugin lifecycle requests through [[plugin-factory-router]] first.

Inputs

• request text
• optional path/source
• constraints and trust requirements

Outputs

Return a routing handoff object with:

• schema_version
• execution_mode
• selected_lane
• next_skill
• required_inputs
• optional blocked_by
• confidence

Workflow

Use the detailed routing protocol in references/workflow.md.

Apply the context-disposition policy: move important still-valid context to references, and intentionally discard stale, duplicated, unsafe, superseded, or low-signal text.

Execution Boundaries

Apply the OpenAI-style plugin design contract when ambiguity affects side-effect class, package boundary, child-skill separation, user steering, or plugin output shape. Route once; do not execute lane logic from this helper.

Plugin Router owns lane selection, missing-input reporting, and handoff shape. It does not scaffold, harden, install, refresh projections, mutate marketplace state, or make release-readiness claims.

Read when:

• You need full lane-selection and handoff protocol details: references/workflow.md.
• You need side-effect, context-minimization, or user-control routing checks: OpenAI-style plugin design contract.
• You need to choose whether plugin factory work should build a new artifact, improve an existing one, stay docs-only, or stop: First-principles factory gate.

For non-trivial factory work, include first_principles_gate or an explicit first_principles_gate_status: not_applicable with the reason in the output or handoff before claiming readiness.

Examples

• "Create a new plugin with marketplace entry." -> route to [[plugin-creator]]
• "Harden this imported plugin before release." -> route to [[plugin-builder]]
• "Install this plugin from GitHub and verify visibility." -> route to [[plugin-installer]]

Validation

bash Infrastructure/scripts/validation-and-linting/validate_skill_authoring_family.sh

Fail fast: stop at first failed gate and report blocker text.

Constraints

• redact secrets and sensitive data by default
• no lane-specific execution

Anti-Patterns

• executing lane logic before routing is complete
• routing by preference instead of explicit intent evidence
• emitting a handoff without required inputs/missing data

Failure Mode

• Stop when one request can validly route to multiple lanes with different side-effect classes, ownership boundaries, or validation gates.
• Ask one blocking question or return blocked_by instead of guessing the lane.

Gotchas

• Router confidence is not execution authorization.
• A plugin lifecycle request may contain skill work; route the plugin boundary first, then hand off skill hardening only when ownership is explicit.
• Marketplace or install intent changes the side-effect class even if the user phrases it as a review.
