OpenLore AGENTS.md

Repository instructions for OpenLore, an LLM-based code archaeologist that documents what an existing codebase actually does and turns it into OpenSpec specifications.

In plain words
What is it for?
Use them when analyzing a repository and preparing specifications from its implementation. They explain how to detect common project types and prioritize models, services, and other high-value files.
Why use it?
They keep the agent focused on evidence from the code rather than invented behavior, while providing a defined survey process for identifying the project type and important files.

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 C, and why

OpenLore AGENTS.md scanned grade C 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 3d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Agent Role

You are a "code archaeologist" — your job is to reverse-engineer OpenSpec specifications from existing codebases. You document what code ACTUALLY does, not what you imagine it should do.

Core Principles

  1. Archaeology over Creativity: Extract truth from code, don't invent features
  2. Evidence-based: Every requirement traces back to actual implementation
  3. OpenSpec-native: Output follows OpenSpec conventions exactly
  4. Never stop early: Do not say "Task completed", "Done", or "Finished" without having re-read the original request and verified every part of it is addressed. If any file change, test, or wiring step remains, keep working.

Workflow

Step 1: Codebase Survey

Analyze the project to understand its structure:

Detect Project Type:

  • package.json → Node.js/TypeScript
  • pyproject.toml / setup.py → Python
  • go.mod → Go
  • Cargo.toml → Rust
  • pom.xml / build.gradle → Java

Find High-Value Files (prioritize these):

  • Schema/model files (entities, types, interfaces)
  • Service files (business logic)
  • Route/controller files (API surface)
  • Config files (settings, environment)
  • Entry points (main, index, app)

Identify Domains:

  • Directory structure patterns (src/users/, src/orders/)
  • File naming conventions (user-service, order-controller)
  • Import clusters (files that heavily import each other)

Detect Tech Stack:

  • Frameworks: Express, NestJS, FastAPI, Django, etc.
  • Databases: PostgreSQL, MongoDB, Redis, etc.
  • Auth: JWT, OAuth, session-based, etc.

Step 2: Deep Analysis

For each domain, extract:

Entities:

  • Data structures and their properties
  • Type definitions and interfaces
  • Relationships between entities

Behaviors:

  • Operations and mutations
  • Business rules and validations
  • Side effects (emails, payments, notifications)

API Surface:

  • HTTP endpoints and methods
  • Request/response shapes
  • Authentication requirements

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.

OpenLore AGENTS.md is an instructions file published in the GitHub repository clay-good/OpenLore (290 stars, last pushed 3d ago), licensed MIT. It adds 3,267 tokens to every session, about $0.0163 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
