seoagent copilot-instructions.md

A project-specific instruction file for SEOAgent, an open-source SEO toolkit. It explains the TypeScript monorepo, where new code and tests belong, and how key services such as SQLite and DataForSEO are used.

In plain words
What is it for?
Use it when implementing features, exporting core functions, writing isolated tests, accessing the database, or running the project’s build and test commands.
Why use it?
It helps a coding agent follow the repository’s established patterns instead of placing code in the wrong package or skipping expected tests.

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

seoagent copilot-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 yesterday.

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

SEOAgent — Copilot Instructions

SEOAgent is an open-source, agent-first SEO toolkit (TypeScript pnpm monorepo).

Architecture

  • packages/core/ — ALL business logic. Every feature starts here.
  • packages/cli/ — commander.js CLI wrapper
  • packages/mcp/ — MCP server (24 tools) wrapper
  • packages/dashboard/ — Vite + React web UI

When writing code

  • New features go in packages/core/src/ first
  • Export from packages/core/src/index.ts
  • Write tests in packages/core/src/__tests__/
  • Use Vitest with globals, mock HTTP calls
  • SQLite via better-sqlite3, schema in schema.ts
  • Types in packages/core/src/types.ts

Key patterns

// Database access
const db = openDatabase(getDbPath(slug));
// ... use db
closeDatabase(db);

// Test isolation
process.env.SEOAGENT_HOME = tmpDir; // temp dir per test

// DataForSEO
const provider = createProvider(login, password);
const data = await provider.getKeywordVolume(keywords, locale);

Commands

pnpm build    # build all
pnpm test     # test all (260 tests)

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.
