knowledge-manager: Instructions file for Codex

AGENTS.md

knowledge-manager AGENTS.md is an instructions file for Codex, OpenCode from treylom/knowledge-manager. It costs 2,058 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding assistants working on knowledge-manager. They explain the repository's purpose, the files to read first, and how placeholder paths keep the project portable.

In plain words
What is it for?
They help agents safely modify skills, agents, commands, and their mirrored configuration files in this repository.
Why use it?
They prevent agents from hardcoding one user's personal folders and breaking the setup for other users.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is treylom/knowledge-manager's own configuration. It tells Codex and OpenCode how to work on knowledge-manager 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 knowledge-manager 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

knowledge-manager 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Generic AI agent contract

This file is the vendor-neutral version of CLAUDE.md. If you are an AI coding assistant other than Claude Code (e.g. Codex, Cursor, Gemini, Antigravity, OpenCode, an autonomous agent framework, or a future model), read this file before you modify anything in this repository.


Repository Identity

  • Name: knowledge-manager
  • Type: Claude Code / Antigravity skill + agent + command distribution repo
  • Primary purpose: Ingest content (web, PDF, YouTube, social, chat logs) and file it as structured notes in the user's Obsidian vault (or Notion, or local markdown).
  • Deployment model: Users git clone this repo, run a setup wizard, and the wizard rewrites placeholder tokens in every skill file with the user's personal paths.
  • Key invariant: The committed source tree is portable. It contains {{PLACEHOLDER}} tokens, never one user's hardcoded paths.

Read First

Read these files in this order before making any edit:

  1. CLAUDE.md — the same contract written for Claude Code, with a worked example of source-vs-substituted file forms.
  2. README.md — end-user documentation; see the ## Installation & Configuration section for how the placeholder system is presented to users.
  3. docs/vault-path-configuration.md — full technical reference: config schema, substitution algorithm, skip-worktree mechanism, troubleshooting.

If you are unable to read those files for any reason, stop and ask the user to paste their contents rather than guessing.


Placeholder Contract (CRITICAL)

The following 5 tokens appear verbatim in committed source files and must be preserved whenever you edit a skill, agent, or command file:

Token Semantic meaning
{{VAULT_PATH}} Absolute path to the user's Obsidian vault directory
{{VAULT_NAME}} Basename of {{VAULT_PATH}} (the vault folder name, used by Obsidian CLI --vault argument)
{{OBSIDIAN_CLI}} Absolute path to the Obsidian CLI executable (may be empty string if not installed)
{{ZETTELKASTEN_ROOT}} Vault-relative path to the Zettelkasten root folder (default: Zettelkasten)
{{RESEARCH_ROOT}} Vault-relative path to the research/MOC root folder (default: Research)

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.
