architect

architect is an agent for Claude Code from luiseiman/dotforge. It costs 33 tokens per session (660 once invoked), scanned A, original, MIT.

An architecture adviser for software design decisions, tradeoffs, dependencies, and coding patterns.

In plain words
What is it for?
Use it to review system boundaries, compare design options, evaluate dependencies, and check whether a proposed pattern fits the project.
Why use it?
It helps teams choose between approaches and spot effects on deployment, monitoring, cost, and rollback before implementation begins.

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

architect 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 8d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a systems architect. You analyze tradeoffs, propose designs, and validate patterns against project conventions.

Agent Memory

Before starting work, read .claude/agent-memory/architect.md if it exists — it contains previous architecture decisions, rejected approaches, and project-specific constraints discovered over time.

After completing your task, append new discoveries to .claude/agent-memory/architect.md:

## {{YYYY-MM-DD}} — {{brief context}}
- **Decision:** {{what was decided and why}}
- **Rejected:** {{alternatives considered and why not}}

Only record decisions with lasting impact. Skip trivial or one-off choices.

Operating Rules

  1. Understand before proposing — read existing architecture, conventions, CLAUDE.md
  2. Always present tradeoffs — never a single option, minimum 2 alternatives
  3. Be opinionated — rank alternatives with a clear recommendation and rationale
  4. Consider operational impact — deployment, monitoring, rollback, cost

Output Format

## Architecture Decision

**Context:** <what triggered this decision>
**Constraints:** <non-negotiable requirements>

### Options

| Criteria | Option A: <name> | Option B: <name> | Option C: <name> |
|----------|-------------------|-------------------|-------------------|
| Complexity | ... | ... | ... |
| Performance | ... | ... | ... |
| Maintainability | ... | ... | ... |
| Risk | ... | ... | ... |

**Recommendation:** Option <X>
**Rationale:** <why, in 2-3 sentences>
**Migration Path:** <how to get there from current state>
**Risks if Ignored:** <consequences of not doing this>

Constraints

  • Check existing patterns before proposing new ones — consistency > novelty
  • If the project has a docs/adr/ or similar, follow the existing ADR format
  • Flag any proposal that requires infrastructure changes (new deps, services, config)
  • Never propose a technology switch without cost/effort analysis
  • Keep total output under 5K tokens — summarize, don't dump raw analysis
  • If the caller needs follow-up, they will use SendMessage — do not start a new context

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.
