mcp-dockhand: Instructions file for GitHub Copilot

.github/instructions/gemini-review.instructions.md

mcp-dockhand gemini-review.instructions.md is an instructions file for GitHub Copilot from strausmann/mcp-dockhand. It costs 283 tokens per session, scanned A, original, MIT.

A code-review guide for an MCP server that wraps the Dockhand REST API, a web interface for managing Dockhand. It requires checking the wrapper against Dockhand's actual routes, methods, request data, and communication protocol.

In plain words
What is it for?
Use it when changing or reviewing Dockhand MCP tools, especially their endpoints, HTTP methods, parameters, validation, path handling, configuration merging, and tests.
Why use it?
It catches mismatches between the tool and the service it represents, as well as unsafe paths, incomplete parameter descriptions, unnecessary requests, and weak tests.

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

mcp-dockhand gemini-review.instructions.md 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 1mo 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.

What it actually says

Gemini Code Assist Review Instructions

This repository wraps the Dockhand REST API (https://github.com/finsys/dockhand) into MCP tools.

Upstream Verification (CRITICAL)

For every MCP tool change, verify against the upstream Dockhand source:

  • API Routes: src/routes/api/**/+server.ts in finsys/dockhand defines the actual endpoints
  • HTTP Methods: Each +server.ts exports named functions (GET, POST, PUT, DELETE, PATCH)
  • Request Bodies: Check what the route handler actually parses from the request
  • Hawser Protocol: internal/protocol/messages.go in finsys/hawser for agent communication

If an MCP tool uses a different HTTP method or parameter name than the upstream source, flag as HIGH.

Code Quality Checks

  1. All path parameters must use encodePath() (path injection prevention)
  2. All Zod parameters must have .describe() annotations
  3. No Record<string, unknown> — use explicit typed parameters
  4. additionalConfig/additionalSettings merged BEFORE explicit fields
  5. No unnecessary API calls (don't fetch just to read connectionType)
  6. Tests must actually validate what they claim (no loose string matching)
  7. API schema (docs/dockhand-openapi.json) must stay deterministic
Changes

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.
