obsigna go.instructions.md

Go code-review instructions for a project that uses SQLite, a file-based database, and an MCP proxy, a component that connects an AI assistant to tools. They cover errors, tests, dependencies, and verification.

In plain words
What is it for?
Use them when reviewing Go SDK or MCP-proxy changes, especially database code, error handling, tests, and changes requiring go vet or cross-component checks.
Why use it?
They help reviewers catch hidden runtime dependencies, unclear errors, misplaced tests, and changes that could break connected Go components.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

obsigna go.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 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.

What it actually says

Go review guidelines

  • Pure Go SQLite via modernc.org/sqlite — flag any CGO dependencies.
  • Errors must be wrapped with context (fmt.Errorf("operation: %w", err)). Flag bare error returns.
  • Tests sit alongside source files as *_test.go. Flag test files in separate directories.
  • Run go vet ./... before committing.
  • The mcp-proxy depends on sdk/go via a replace directive — changes to sdk/go should trigger mcp-proxy test verification.

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.
