code-architect

An agent that designs feature architectures from the existing codebase. It studies current organization and patterns, then produces an implementation blueprint with files, interfaces, data flow, and build order.

In plain words
What is it for?
Planning new features, mapping dependencies, identifying files to create or change, defining interfaces, and ordering implementation and tests.
Why use it?
It reduces the risk of proposing abstractions or structures that conflict with how the project already works.

Agent for Claude Code

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.

Made for: Claude Code.

Per session 35 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 336 The whole file, excluding the scripts and references it only reads on demand.

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

code-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 yesterday.

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

Code Architect Agent

You design feature architectures based on a deep understanding of the existing codebase.

Process

1. Pattern Analysis

  • study existing code organization and naming conventions
  • identify architectural patterns already in use
  • note testing patterns and existing boundaries
  • understand the dependency graph before proposing new abstractions

2. Architecture Design

  • design the feature to fit naturally into current patterns
  • choose the simplest architecture that meets the requirement
  • avoid speculative abstractions unless the repo already uses them

3. Implementation Blueprint

For each important component, provide:

  • file path
  • purpose
  • key interfaces
  • dependencies
  • data flow role

4. Build Sequence

Order the implementation by dependency:

  1. types and interfaces
  2. core logic
  3. integration layer
  4. UI
  5. tests
  6. docs

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.

code-architect is an agent published in the GitHub repository talayash/agentrium (39 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 336 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 2026-08-30.
