ai-context: Instructions file for Claude Code

AGENTS.md

ai-context AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from dkothule/ai-context. It costs 1,296 tokens per session, scanned A, original, MIT.

A shared instruction file for AI coding assistants working on the ai-context project. It tells them which project notes, rules, plans, and session records to read and follow.

In plain words
What is it for?
Use it to orient an agent, plan larger changes, apply project standards, and continue work from earlier sessions.
Why use it?
It keeps different assistants aligned with the same project context and reduces lost decisions between sessions.

Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is dkothule/ai-context's own configuration. It tells Claude Code, Codex and OpenCode how to work on ai-context 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 ai-context 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

ai-context 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Shared agent adapter

This file is intentionally thin. The single source of truth is .ai-context/, loaded on demand.

Read First (Every Session)

All paths below are relative to .ai-context/.

Always read:

  1. project.overview.md — what this project is
  2. project.tasks.md — what is in flight, blocked, next
  3. Session logs in sessions/ — never _archive/, never _template.md: a. Newest by filename date. If several share that date, order by the time: frontmatter field; where absent, fall back to filename order. b. Scan the # Session: heading of the other same-date logs and read any whose topic relates to the current task. c. If that log's "Next Steps" or "Notes For Next Agent" points at earlier work you are continuing, follow the reference. Read at most 3 logs unless continuation references in (c) require more.

Then read based on task:

  • Writing/modifying code → standards/project.rules.base.md, standards/project.rules.md
  • Release/history context → project.changelog.md
  • Understanding layout → project.structure.md
  • Planning non-trivial work → project.tasks.md, plans/
  • Language/testing → files in standards/

Planning

Before non-trivial work (multi-session, architectural change, external dependency), write a plan to .ai-context/plans/YYYY-MM-DD-<topic>.md using _template.md. Reference the plan from project.tasks.md so it's discoverable. After plan approval, write the file immediately — before any implementation begins.

Execution Contract

  1. Follow .ai-context/standards/project.rules.base.md and project.rules.md.
  2. One logical change per commit; tests run before commit.
  3. Keep .ai-context/ in sync with project state — route each change to the correct file:
    • New architectural decision → project.decisions.md
    • User-visible change → project.changelog.md
    • Task transition (new/done/blocked) → project.tasks.md
    • Plan authored → plans/YYYY-MM-DD-<topic>.md
    • Session close → sessions/YYYY-MM-DD-<topic>.md

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.
