scythe-context-mcp: Instructions file for Codex

AGENTS.md

scythe-context-mcp AGENTS.md is an instructions file for Codex, OpenCode from Lianye-Scythe/scythe-context-mcp. It costs 356 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Scythe Context MCP, a tool that indexes a codebase so an agent can find relevant files, symbols, dependencies, and related code.

In plain words
What is it for?
Use it when exploring unfamiliar code, preparing focused context for a task, tracing imports and dependencies, or checking whether the repository index is current.
Why use it?
It gives the agent a defined way to search a repository while keeping private files, credentials, and generated indexes out of commits and outputs.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is Lianye-Scythe/scythe-context-mcp's own configuration. It tells Codex and OpenCode how to work on scythe-context-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything scythe-context-mcp configures →

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

scythe-context-mcp AGENTS.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 12d 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

Scythe Context MCP Agent Guide

Workflow

  • Start with repo_index_status to check whether .scythe-context/index.sqlite exists, whether files/chunks/symbols/dependencies/embeddings are present, and whether freshness reports stale files.
  • If metadata is missing or stale, run repo_reindex with dry_run=false.
  • Set index_embeddings=true only when semantic search is needed. This sends chunk text to the configured Gemini-compatible endpoint.
  • Prefer repo_context_pack for task-oriented code lookup. It combines hybrid search, snippet budgeting, related-file metadata, bounded multi-hop traversal, and suggested paths.
  • Use repo_semantic_search when debugging raw ranking behavior. Prefer a smaller max_context_chars for broad exploration and increase it only when the returned snippets are not enough.
  • After a search result identifies a useful file, call repo_related_files for that file when you need a focused view of its symbols, imports, and reverse imports.

Privacy

  • Do not commit .scythe-context/, legacy .repo-beacon/, or local/.
  • Do not print API keys, proxy tokens, or contents of files under local/secrets/.
  • Treat third-party Gemini-compatible proxy endpoints as remote services that can see query and chunk text.

Development

  • Keep indexing, storage, provider, search, and MCP tool wiring decoupled.
  • Preserve stable chunk row ids for unchanged files so embedding cache remains useful.
  • Add focused tests when changing scanner, chunker, schema, ranking, formatting, or provider compatibility.
  • Run npm test, npm run build, and npm audit --omit=dev before committing a completed development slice.
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.
