pneuma-skills: Instructions file for Codex

AGENTS.md

pneuma-skills AGENTS.md is an instructions file for Codex, OpenCode from pandazki/pneuma-skills. It costs 3,483 tokens per session, scanned A, original, MIT.

A shared AGENTS.md file that tells coding agents how to work in the Pneuma Skills project, including its tools, structure, and rules.

In plain words
What is it for?
It helps agents understand the project, choose the right commands, and read the relevant rules before editing files.
Why use it?
It keeps agent instructions in one place and prevents different agents from using copied or outdated guidance.

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

This is pandazki/pneuma-skills's own configuration. It tells Codex and OpenCode how to work on pneuma-skills 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 pneuma-skills 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

pneuma-skills 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 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.

How it starts

The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pneuma Skills

Single source of truth for agent instructions. Claude Code reads this via the one-line @AGENTS.md import in CLAUDE.md; Codex and Kimi read this file directly. Never duplicate content into CLAUDE.md — it must stay a single import line.

This startup guide stays below 24 KiB so Codex can read it within its default instruction budget. Architecture details live in Project Guide. Before editing, read the matching domain rules below; their contents are shared by both harnesses.

Product and Architecture

Pneuma Skills is co-creation infrastructure for humans and code agents. It turns an agent's work into a domain-specific environment where a person can watch, participate, and carry the work forward. Four pillars support this: a visual environment, skills, continuous learning, and distribution.

  1. Shared work, two ways to interact. Agents use native file tools; people see documents, decks, boards, and other domain objects. Files remain the canonical surface for persistent work. Viewers consume typed Sources; their optional edits return to the same files. Preserve the connection between what the user points at, what the agent changes, and the visible result. ViewerAddress is the shared object-reference contract.
  2. The viewer is a live player for the task. It renders work as it forms and supports direct edits, structured guidance, and inspection where useful. Design the experience around the person's task and the domain's units. Creation and consumption can have different interactions; partial, waiting, and failed states must remain understandable.
  3. A mode packages a way of working. Its domain model, skill, scripts, seeds, viewer, and quality criteria belong together. The framework supplies shared contracts and runtime services. Mode-specific knowledge stays in the mode; backend-specific knowledge stays behind BackendModule. Capabilities are explicit, so a backend need not pretend to support another backend's tools.
  4. Spend agent judgment where it matters. Interpretation, creation, and tradeoffs need judgment. Established assembly, validation, scheduling, and deterministic interaction paths belong in programs. Put repeatable mechanics in scripts and explain their use in skills. Essential workflow policy must remain usable across the supported harnesses.
  5. Let collaboration accumulate. Sessions persist; optional projects connect work across modes through shared materials, context, and explicit handoffs. Preference skills maintain personal and project memory. Evolution proposes evidence-backed additions and removals to guidance for user review. Modes can be customized and distributed with their working methods intact.

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.
