hive AGENTS.md

A project guide for Hive, a server that gives AI coding assistants access to an Obsidian note vault and can delegate work to local or low-cost workers. It also documents the repository’s architecture and operating rules.

In plain words
What is it for?
Use it when working on the Hive repository, especially before changing code, following its development process, or troubleshooting its orchestration setup.
Why use it?
It tells an assistant which instructions and documentation to read first, where project decisions and task status are stored, and how worker routing works.

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

hive AGENTS.md scanned grade A with 1 finding 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

- **All `subprocess.run` calls MUST catch broad `Exception`**, not just `CalledProcessError` — git invocations on Windows raise things like `FileNotFoundError` that would otherwise crash a write tool.

AGENTS.md

Instructions for AI coding agents (Claude Code, OpenCode, Copilot, Cursor, Codex, Antigravity) operating in this repo.

Behavioural SSOT lives in dotfiles: $DOTFILES_REPO_DIR/AGENTS.md (the dotfiles repo root, resolved per-machine via the path cascade: explicit env → ~/.config/dotfiles/machine.jsonenv-contract.json default; ADR-025). Read it FIRST — Identity, Standing Orders, Decision Hierarchy, Model Selection, Neural Hive protocol, MCP usage rules, Spec-Driven Development gate, and operational rules. This file adds ONLY what is specific to the Hive repo. The Claude-specific tooling overlay is .claude/CLAUDE.md.

What this repo is

Hive — vault-native AI orchestration: a unified MCP server giving AI coding assistants on-demand access to an Obsidian vault plus delegation to local/cheap workers.

Build/operate docs live in docs/ (docs-as-code): docs/adr/ (architecture decisions + sequence-diagrams.md), docs/runbooks/, docs/troubleshooting/, docs/lessons.md. Per-feature specs live in specs/. Task state lives in the bitácora GitHub Project (filter by Repo = hive), not here. The cross-project brain and AI memory live in the maintainer's vault.

Big-picture architecture

Hive is an MCP server (stdio transport, FastMCP framework) with three responsibilities:

  1. Vault tools — query, search, list, write, patch markdown files in an Obsidian vault. All writes auto-commit to git (best-effort; git failure never crashes the server) and validate YAML frontmatter.
  2. Session toolssession_briefing assembles tasks + lessons + git log + health in one call so an AI client gets ~50 lines of context instead of ~800.
  3. Worker toolsdelegate_task and capture_lesson each make one attempt against one OpenAI-compatible worker. No internal fallback: the caller owns the chain, and failures are classified as pool unavailable vs task failed so the caller can tell a retryable one from a real one.

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.

hive AGENTS.md is an instructions file published in the GitHub repository mlorentedev/hive (10 stars, last pushed 7d ago), licensed MIT. It adds 3,040 tokens to every session, about $0.0152 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
