ideate AGENTS.md

Repository instructions for Ideate, a project that builds features for AI agents. They say new capabilities should normally be added as MCP tools first, with a user interface added only when needed.

In plain words
What is it for?
Planning and building Ideate features, deciding whether they belong in the orchestrator or an individual idea, and defining the tool and tests before adding interface work.
Why use it?
They help contributors choose an implementation surface that agents can call, combine, and run from scripts, while keeping unnecessary interface work out of the first version.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 AGENTS.md 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.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Cross-agent guidance for any AI agent (Claude Code, future runners, external orchestrators) working on the Ideate codebase. Claude-specific context lives in CLAUDE.md; this file captures principles that apply regardless of which agent is at the keyboard.

Build features as MCP tools first, UI second

When adding a new capability, the default surface is an MCP tool on the orchestrator (root orchestrator) MCP server, not a UI control.

Why:

  • The orchestrator is the most-used surface — most workflows already start there. A tool exposed there reaches the user without a context switch.
  • Tools compose: the orchestrator can chain rename_idea, add_resource_by_slug, update_idea_by_slug into a single operation. UI buttons can't.
  • Tools are scriptable. A workflow that lives only in the UI can't be triggered from a session, a hook, or another agent.
  • Less code: an MCP tool is a handler + a schema. A UI feature adds React state, routing, styling, Playwright tests, and the back-and- forth between frontend and backend.

The default lift is therefore: pick the right MCP surface (per-idea vs orchestrator), wire the tool, write the test. Stop there.

When to add UI

Only when the operation cannot reasonably be driven from a conversation. The clearest case is starting an interactive session — the user has to physically attach to a PTY, so a button is unavoidable. Other cases that have justified UI in the past:

  • Live terminal interaction (the xterm canvas is the UI).
  • Markdown / diff review surfaces — the human reads a rendered diff and clicks comment widgets that don't translate to text.
  • Status indicators that need to stay visible across navigations (footer toggles, session bar chips).

If a feature is a one-shot data mutation ("rename this idea", "drop old reviews", "add a tag") it belongs in MCP. If it's a continuous visual state ("show me the agent's terminal", "render this diff"), it belongs in the UI.

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.
