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

kiro-for-codex 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 5d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Kiro for Codex

This file defines the agent contract and serves as the index to project guidance. It applies repo‑wide unless overridden by a nested AGENTS.md.

Steering Documents

  • Use Steering as the authoritative source for product, technical, and structural guidance.
  • Location: .codex/steering/product.md, .codex/steering/tech.md, .codex/steering/structure.md.
  • Access: Resolve paths via ConfigManager (e.g., ConfigManager.getPath('steering')). Do not hardcode absolute paths.
  • Mutations: Treat Steering as read‑only; perform changes only via feature flows (Init/Refine/Delete), not ad‑hoc edits.
  • Usage: When producing outputs, summarize applicable Steering points and cite the specific file/section; do not restate content verbatim.

Decision Precedence

  1. Code-level flags and constraints in "src/constants.ts"
  2. Steering documents under ".codex/steering/*.md"
  3. This AGENTS.md contract (general repository conventions)
  4. Generic assumptions (avoid unless explicitly allowed)

Agent Behavior Contract

  • Use CodexProvider for CLI operations; build commands with CommandBuilder; execute via ProcessManager. Do not spawn child processes directly.
  • Respect feature flags and constraints in src/constants.ts and any package.json contributes.* gating.
  • Logging: Use the shared OutputChannel; log key lifecycle and error paths; avoid noisy logs.
  • Error handling: Use centralized services (ErrorHandler, RetryService); avoid ad‑hoc try/catch loops.
  • Performance/UX: Do not block the extension host; for long tasks use split terminals and VS Code progress notifications.
  • Reference Steering for naming, boundaries, and directory layout instead of restating rules here.

Paths & I/O

  • Workspace I/O: Prefer VS Code FS APIs (vscode.workspace.fs) for read/write/create.
  • Path resolution: Use ConfigManager for all .codex/** paths; avoid absolute paths.
  • Write boundaries: Only write within .codex/**, the workspace, or VS Code storage as allowed by project rules.
  • Steering: Do not overwrite files under .codex/steering directly; use feature flows.

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.
