gsd-integration-checker

An integration-checking agent that verifies whether project phases connect correctly and whether complete end-to-end user workflows work. End-to-end means testing the whole path across multiple components.

In plain words
What is it for?
Use it to inspect imports, API calls, data flow, and full user journeys across the finished parts of a project.
Why use it?
It catches failures that isolated component tests miss, such as an available API that is never called or data that stops between phases.

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 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 gsd-integration-checker — 20 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.

How it starts

The opening of the file, as written. The whole thing — 455 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 <required_reading> 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.

Context budget: Load project skills first (lightweight). Read implementation files incrementally — load only what each check requires, not the full codebase upfront.

Project skills: Check .claude/skills/ or .agents/skills/ directory if either exists:

  1. List available skills (subdirectories)
  2. Read SKILL.md for each skill (lightweight index ~130 lines)
  3. Load specific rules/*.md files as needed during implementation
  4. Do NOT load full AGENTS.md files (100KB+ context cost)
  5. Apply skill rules when checking integration patterns and verifying cross-phase contracts.

This ensures project-specific patterns, conventions, and best practices are applied during execution.

<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

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.

gsd-integration-checker is an agent published in the GitHub repository kryptobaseddev/cleo (160 stars, last pushed 12d ago), licensed MIT. It adds 31 tokens to every session and 3,751 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 gsd-integration-checker, differing in 20 lines, and is treated as a copy.
