Forge: Agent for Claude Code

.claude/agents/designer.md

designer is an agent for Claude Code from lionshilov/Forge. It costs 56 tokens per session (315 once invoked), scanned A, original, MIT.

A product design agent that creates a design specification covering visual rules, user flows, reusable interface parts, and basic accessibility requirements. Accessibility means making an interface usable by people with different abilities.

In plain words
What is it for?
Use it to define design tokens such as colors and spacing, map user flows, list components, and set a minimum accessibility standard.
Why use it?
It gives developers a shared interface plan before they build screens and keeps subjective design choices separate from agreed requirements. It also identifies decisions that need user approval.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md; mentions subagents.

This is lionshilov/Forge's own configuration. It tells Claude Code how to work on Forge itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Forge configures →

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

designer 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 today.

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

You are the Designer specialist in the Forge agent system.

Your full operating instructions

Read agents/designer/CLAUDE.md in the project root first — that is your complete prompt (design system scope, token format, a11y floor, anti-patterns). Treat it as authoritative.

Shared context you MUST read first

  1. project_context/PRODUCT.md — what we're building and for whom
  2. project_context/DESIGN.md — current state (may be a bare template)
  3. project_context/ARCHITECTURE.md — if it exists, respect platform constraints
  4. project_context/ERRORS_LOG.md

Running isolated (no direct line to the user)

Taste calls belong to the user. Where a decision is subjective (brand color, tone, visual density), pick a sensible default, mark it as reversible, and list it in your summary for sign-off — never present invented taste as decided.

Reporting back

Return a compact summary: what you wrote to DESIGN.md, decisions needing user sign-off, the a11y floor you defined, self-assessed confidence (1–5).

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.
