description	Intelligent orchestrator for the Platonic Coding lifecycle. Auto-detects the user's intent and project state, then routes to the right next step—brainstorm a design, initialize a project, run the recovery flow for existing code, formalize drafts into RFCs, refine specs, implement from guides with tests, or review code compliance. Single entry point for the complete specification-driven development lifecycle, with structured design exploration built in.

Platonic Coding

Intelligent orchestrator for the complete specification-driven development lifecycle. Auto-detects the user's intent and project state, then executes the appropriate workflow phase—brainstorming, initialization, specification management, implementation, or review. Structured design exploration (formerly the standalone platonic-brainstorming skill) is built in as BRAINSTORM mode.

When to Use This Skill

Use this skill when you need to:

• Brainstorm a design through collaborative dialogue before committing to an RFC
• Bootstrap a new project with Platonic Coding infrastructure
• Adopt Platonic Coding for an existing codebase (recover specs from code)
• Manage RFC specifications (validate, refine, generate indices)
• Implement features from RFC specs with guides and tests
• Review code for spec compliance
• Run the full workflow from design → RFC → code → review

Keywords: platonic coding, brainstorm, discuss, investigate, specs, RFC, implementation, review, workflow, spec-driven, initialization

Intelligent Auto-Detection

Auto-detects intent and project state when invoked without specific instructions. See references/REFERENCE.md for the full decision tree.

Intention Detection (runs first)

Before inspecting project state, scan the user's natural-language request for intent keywords that signal a desire to explore rather than immediately produce an artifact:

• Trigger words (case-insensitive): brainstorm, discuss, investigate, explore, deep analysis, deep dive, think through, design exploration, trade-offs, what's the best approach.
• Match → enter BRAINSTORM mode (references/BRAINSTORM/brainstorm.md), regardless of project state. The user wants to explore first; project-state detection resumes at handoff.
• Exception: if the request uses a canonical operation name (impl-full, review, specs-refine, init-scaffold, workflow --phase <N>, brainstorm), the explicit operation wins — don't reroute it.

Project-State Detection (when no intent keywords)

Quick Reference:

• No Platonic infrastructure (no .platonic.yml and no docs/specs/) → INIT mode (scaffold new or recover existing)
• RFCs but no guides → Phase 2 (implementation)
• Guides + code → Phase 3 (review) or resume Phase 2

Note: .platonic.yml is optional. The skill auto-detects project metadata (name, language, framework) from host manifests and uses built-in default paths (docs/specs, docs/impl, docs/drafts). A .platonic.yml is only needed to override defaults or set custom spec stages.

Override with canonical operations: brainstorm, init-scaffold, init-scan, specs-refine, impl-full, review, workflow --phase <N>.

Core Workflow Phases

Phase	Focus	Output	Brainstorming
1	RFC Specification	Draft → RFC → specs-refine	✅ Optional (BRAINSTORM mode)
2	Implementation	Guide → Code + Tests	✅ Optional (BRAINSTORM mode)
3	Review	Compliance report	❌

Phases run sequentially (full workflow) or independently (explicit invocation). BRAINSTORM mode is an optional entry ramp to Phases 1 and 2. See references/WORKFLOW/workflow-overview.md for details.

Operation Modes

BRAINSTORM Mode

Structured design exploration through collaborative dialogue. Produces an approved design draft (docs/drafts/), then presents post-draft alternative paths (see below). Entered by intent keywords, or explicitly. No code, RFC, or scaffolding is produced until the design is approved.

Examples: brainstorm the message queue design, discuss how auth should work, investigate options for caching.

INIT Mode

Bootstrap Platonic Coding infrastructure. Operations: init-scaffold, init-scan, init-plan-modular-specs, init-recover-*.

Note: init-scaffold creates directories and templates but does not create .platonic.yml by default — project metadata is auto-detected from host manifests and default paths are used. A .platonic.yml is only created when the user explicitly requests non-default paths or custom spec stages.

Examples: init-scaffold for project "Acme", init-scan then recover specs.

SPECS Mode

Manage RFC specifications. Operations: specs-refine (comprehensive), specs-generate-*, specs-validate-*, specs-check-*.

Examples: specs-refine, specs-generate-index.

IMPL Mode

Translate RFCs to guides and code. Operations: impl-full (default), impl-create-guide, impl-code, impl-validate-guide, impl-update-guide.

Confirmation Gates: Pauses after impl guide and coding plan. Override with "no confirmations".

Examples: impl-full for RFC-042, impl-code from IG-001.

REVIEW Mode

Validate code against specs. Generates report-only by default (no code changes). 6-step process: understand specs → checklist → map → review → discrepancies → report.

Examples: review src/auth/ against RFC-001, review for gap analysis.

WORKFLOW Mode

Orchestrate full 3-phase flow. See references/WORKFLOW/workflow-overview.md.

Examples: workflow --phase 1, workflow starting with brainstorm.

Post-Draft Alternative Paths

After BRAINSTORM mode produces an approved design draft, the skill does not assume "create a new RFC" is the only next step. It checks docs/specs/ and docs/impl/ for related existing RFCs/IGs, then presents a routing menu (full table in references/BRAINSTORM/brainstorm.md):

1. Pause at each phase gate — careful, default; approve every confirmation gate
2. Quick pass — run multiple phases straight through, no further confirmations (quick fixes)
3. Update an existing RFC — revise a related RFC instead of spawning a new one
4. Create a new RFC — formalize the draft into a fresh RFC-NNN (next sequential NNN unless user overrides)
5. Update an existing IG — refine an existing implementation guide via impl-update-guide
6. Create a new IG — generate a fresh IG-XXX via impl-create-guide (next sequential XXX unless user overrides)

The menu leads with a recommendation based on what was found. The user picks by number; each path maps to existing canonical operations.

Default Paths & Templates

Artifact	Path	Naming
Drafts	docs/drafts/	YYYY-MM-DD-<topic>-design.md
RFCs	docs/specs/	RFC-NNN-<name>.md (NNN = exactly 3 digits; strict sequence)
Guides	docs/impl/	IG-XXX-<name>.md (XXX = exactly 3 digits; strict sequence)

Templates in assets/ use {{PLACEHOLDER}} syntax.

Best Practices

1. Trust auto-detection; override with explicit operations when needed
2. Review generated artifacts (all Draft status)
3. Run specs-refine regularly
4. Use confirmation gates—don't skip unless confident (or use quick-pass routing)
5. Review mode is report-only by default

Dependencies

• Read/write to project directories
• Access to host manifests (Cargo.toml, package.json, pyproject.toml, go.mod, etc.) for auto-detection
• .platonic.yml is optional — only read if present for path/stage overrides
• Understanding of target language/framework
