About octopus-architecture

octopus-architecture is a Codex CLI skill for evidence-based architecture reviews. It examines implementation, callers, tests, change history, and failure behavior to propose an interface, compare design alternatives, and state a decision without authorizing automatic refactoring.

Key features

  1. 01Evidence-based architecture review
  2. 02Inspect callers, tests, and source history
  3. 03Compare two design alternatives
  4. 04Define migration and test impact
  5. 05Optional bounded independent review

Use cases

  1. 01Review a proposed module boundary
  2. 02Assess a simplification against callers and tests
  3. 03Compare designs for a demonstrated extension

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/nyldn/claude-octopus --skill octopus-architecture

After installing, type/octopus-architecturein Claude Code to confirm it loaded.

Details

From the project README

Host: Codex CLI — This skill was designed for Claude Code and adapted for Codex. Cross-reference commands use installed skill names in Codex rather than /octo:* slash commands. Use the active Codex shell and subagent tools. Do not claim a provider, model, or host subagent is available until the current session exposes it. For host tool equivalents, see skills/blocks/codex-host-adapter.md.

Architecture review

Load skills/blocks/engineering-method-selection.md from the installed plugin and apply only the methods relevant to this task. Preserve this entry point's execution contract and output format. Read referenced skills as instructions; do not invoke the current command recursively or add provider calls from a seat.

Run this method on the current host. A routine architecture review makes zero additional provider dispatches. --peer-review, an explicit independent-review request, or an existing risk policy may add one bounded external reviewer through Octopus routing. Report incomplete independent coverage if that reviewer cannot read the source or does not return a grounded contribution.

Method

Read and apply skills/blocks/architecture-simplification.md from the installed plugin root. Pin the source revision and inspect implementation, callers, tests, recent churn, and failure behavior before recommending a boundary.

For a single simplification, produce one evidence-backed interface. For a design choice, produce two alternatives from the same immutable requirements:

  • Draft A minimizes caller knowledge and configuration.
  • Draft B makes the next demonstrated extension easier.

Label two host-generated drafts as correlated alternatives from one model. If an independent reviewer is authorized, send it the same source and requirements but not Draft A before its first response. Transport diversity does not prove model family diversity. Unknown family means unknown independence.

Completion

Return Evidence, Caller contract, Proposed interface, Migration, Test impact, and Decision. The decision is keep, simplify, or investigate. simplify requires exact source evidence and a concrete caller example. A design review never authorizes an automatic refactor.

LSP Integration

When the host exposes language-server tools, use document symbols, workspace symbols, definitions, and references to confirm module boundaries and caller relationships before proposing an interface. Treat LSP results as an index: verify consequential claims against source and tests, and fall back to repository search when the language server is unavailable or incomplete.
