code-architect

An agent that studies an existing codebase and produces a feature architecture plan with files, interfaces, data flow, dependencies, and implementation order.

In plain words
What is it for?
It helps plan features, identify relevant code conventions and boundaries, order tests and implementation, and prepare a blueprint compatible with test-driven development, where tests guide the code.
Why use it?
It reduces the risk of proposing abstractions or file structures that conflict with the project's existing patterns.

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 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.

Origin

This is a copy

88% identical to code-architect — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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, tests-first. This project drives non-trivial work through tdd-guide (and, when .specify/ exists at the repo root, through spec-kit's /specify/plan/tasks). Your blueprint must be compatible with that flow:

  1. types and interfaces
  2. failing tests for the behaviour the feature must deliver
  3. core logic — implement until tests go green
  4. integration layer
  5. UI
  6. user-facing docs (never source-file docstrings; see CLAUDE.md)

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 ifixai-ai/claude-strike (20 stars, last pushed 4mo ago), licensed MIT. It adds 35 tokens to every session and 425 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to code-architect, differing in 15 lines, and is treated as a copy.
