Agents-of-Abyss: Instructions file for Codex

AGENTS.md

Agents-of-Abyss AGENTS.md is an instructions file for Codex, OpenCode from 8Dionysus/Agents-of-Abyss. It costs 1,103 tokens per session, scanned A, original, Apache-2.0.

Repository instructions that tell a coding agent which guidance to read before editing files and where each rule applies.

In plain words
What is it for?
Use them to guide work across a repository, resolve conflicts between root and nested instructions, and run the right checks before closing a change.
Why use it?
They reduce mistakes caused by ignoring local rules, ownership boundaries, generated files, or required validation steps.

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

Agents-of-Abyss 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 7d 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.

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Applies to

This root card applies repository-wide unless a nearer AGENTS.md supplies a narrower local delta.

Role

Agents-of-Abyss is the constitutional and ecosystem center of AoA. It owns ecosystem identity, charter, layer map, federation rules, program direction, compact center registries, and center-local measurement over those surfaces. It keeps the long arc legible without absorbing specialized implementation.

Skills, techniques, evals, memory, routing, KAG, playbooks, shared statistics, roles, runtime behavior, and ToS authored meaning remain with their owner repositories. Quest, checkpoint, progression, recurrence, or RPG language here must not imply live runtime state, ledger authority, or unreviewable autonomy.

Read before editing

Select only the route that can change the current task's interpretation. A nearby README is a human surface: read it when its explanation, package map, provenance, compatibility, or usage contract is material, not merely because the file exists. Use docs/START_HERE_ROUTE_CONTRACT.md only when the center entry-route contract itself changes.

Route mode First owner surface
first-reading README.md
root-editing docs/ROOT_SURFACE_LAW.md
direction-change ROADMAP.md
ownership-routing docs/REPO_ROLES.md
mechanic-change nearest mechanics/**/AGENTS.md; use the human atlas only when needed

Route source-linked knowledge to Tree-of-Sophia; roles and progression to aoa-agents; scenarios and questlines to aoa-playbooks; typed helpers and control-plane behavior to aoa-sdk; runtime and storage to abyss-stack; and skill, technique, eval, memo, KAG, routing, or stats meaning to its named owner.

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.
