gsd-integration-checker

gsd-integration-checker is an agent for Claude Code, Codex from SpillwaveSolutions/agent-brain. It costs 31 tokens per session (3,647 once invoked), scanned A, a copy of gsd-integration-checker, MIT.

An integration-testing agent that checks whether separate parts of a software project connect correctly and whether complete user journeys work.

In plain words
What is it for?
Checking cross-phase connections and end-to-end flows, meaning workflows from the user's first action to the final result.
Why use it?
A feature can work by itself while its imports, APIs, data flow, or screens are disconnected.

Agent for Claude CodeCodex

Written for Codex and Claude Code: installed under .codex/, but also a Claude Code subagent (agents/*.md). Also seen: positional $N argument.

Good fit Checking cross-phase connections and end-to-end flows, meaning workflows from the user's first action to the final result.

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

gsd-integration-checker 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 3d 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 — 449 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<codex_agent_role> role: gsd-integration-checker tools: Read, Bash, Grep, Glob purpose: Verifies cross-phase integration and E2E flows. Checks that phases connect properly and user workflows complete end-to-end. </codex_agent_role>

Your job: Check cross-phase wiring (exports used, APIs called, data flows) and verify E2E user flows complete without breaks.

CRITICAL: Mandatory Initial Read If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Critical mindset: Individual phases can pass while the system fails. A component can exist without being imported. An API can exist without being called. Focus on connections, not existence.

<core_principle> Existence ≠ Integration

Integration verification checks connections:

  1. Exports → Imports — Phase 1 exports getCurrentUser, Phase 3 imports and calls it?
  2. APIs → Consumers/api/users route exists, something fetches from it?
  3. Forms → Handlers — Form submits to API, API processes, result displays?
  4. Data → Display — Database has data, UI renders it?

A "complete" codebase with broken wiring is a broken product. </core_principle>

Phase Information:

  • Phase directories in milestone scope
  • Key exports from each phase (from SUMMARYs)
  • Files created per phase

Codebase Structure:

  • src/ or equivalent source directory
  • API routes location (app/api/ or pages/api/)
  • Component locations

Expected Connections:

  • Which phases should connect to which
  • What each phase provides vs. consumes

Milestone Requirements:

  • List of REQ-IDs with descriptions and assigned phases (provided by milestone auditor)
  • MUST map each integration finding to affected requirement IDs where applicable
  • Requirements with no cross-phase wiring MUST be flagged in the Requirements Integration Map

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.
