ideate

A guided ideation stage for exploring and assessing different directions before choosing one. It runs a defined sequence of agents and saves their ideas in a task workspace.

In plain words
What is it for?
Use it when you explicitly start the Harmonia ideate stage to generate options, compare them, and record the chosen planning material.
Why use it?
It keeps early planning from jumping to the first solution and preserves the results for later work. It also checks that the expected output files were created.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ideate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Your working contract is the 4 rules; their digest is injected at session start - read ${CLAUDE_PLUGIN_ROOT}/core/RULES.md in full only if that digest is not in your context. Read the ideate stage from ${CLAUDE_PLUGIN_ROOT}/core/lifecycle.yaml - its agent sequence and artifact contract are authoritative; do not hardcode them.

  1. Workspace: run bash ${CLAUDE_PLUGIN_ROOT}/bin/workspace.sh mint --repo . --slug <short-task-slug> (entry stage). If it refuses because an incomplete workspace exists, surface its message verbatim and stop - the user either continues that task (--task <id>) or forces --new.
  2. Dispatch the stage's agents in order (the ideator may run the panel primitive at ${CLAUDE_PLUGIN_ROOT}/core/patterns/panel.md for divergence). Pass the task ask and the workspace path - agents write ideas.md into the workspace, not into conversation (R8).
  3. Confirm the out-artifacts named by the stage exist in the workspace before finishing.

You orchestrate only: no stage logic beyond dispatch, sequencing, and artifact checks (R9).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ideate is a skill published in the GitHub repository foliveira/harmonia (2 stars, last pushed 18d ago), licensed MIT. It adds 33 tokens to every session and 296 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

todos

This chat has a shared, live TODO plan — your tasks for the conversation, which the user also edits. Read this skill and reach for the todo tools whenever a request takes more than a couple of steps. It covers the plan model (group = task, items = its steps; loose items are the user's lane), how to work it: propose…

Use when adding a new workflow skill to pi-thinkrail-workflow, changing an existing workflow skill's role, trigger, handoff, or structure, or checking a workflow skill against the workflow system's rules. Not for authoring general-purpose skills outside this package.

brainstorming

Use this BEFORE any creative or feature work: building a new feature, adding functionality, changing behavior, or making a nontrivial design decision. Turns the user's request into a validated design — recorded as a spec-graph task-spec — before any implementation. Do not skip this because a change looks small.

Use when finished work needs to ship as a pull request, or when the ask is about a PR — creating one, bringing it up to date, adding screenshots, watching its checks, or addressing its review comments. Not for reviewing a PR you are not shipping.

writing-specs

Use when a workflow step drafts or revises a spec artifact — a goal-and-requirements, an architecture, or a module SPEC — or when a workflow skill names it at such a step. The shared quality bar for specs — not a workflow, nothing to execute.

clarify

Adaptive requirements clarification with auto-depth routing. Shallow (Q&A) for simple tasks, Deep (exploration + DRAFT + PLAN) for complex ones. Escalates automatically when ambiguity persists.
