Instructions file for CodexOpenCode

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

This is LFDT-Lineth/lineth-monorepo's own configuration. It tells Codex and OpenCode how to work on lineth-monorepo 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 lineth-monorepo 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

lineth-monorepo 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.

AGENTS.md

Documentation Precedence

  • AGENTS.md is the canonical source for repository-wide agent instructions.
  • Tool-specific files should stay concise and link back to AGENTS.md.
  • If instructions conflict, follow AGENTS.md.

Agent Entry Points

  • Codex: AGENTS.md (this file)
  • Cursor: .cursor/rules/documentation.mdc, .cursor/BUGBOT.md, then AGENTS.md
  • Claude Code: CLAUDE.md, then AGENTS.md
  • GitHub Copilot: .github/copilot-instructions.md, then AGENTS.md

Local Agent Workflows

  • squash-bugbot: canonical skill at .agents/skills/squash-bugbot/SKILL.md.
  • Use /squash-bugbot <PR_NUMBER> locally in Codex, Cursor, or Claude Code to triage unresolved bot PR comments.
  • Claude Code exposes the same workflow through .claude/commands/squash-bugbot.md, a symlink to the canonical skill.
  • Requires an authenticated gh CLI with access to read PR comments, write PR comments, resolve review threads, and push the current branch.

Discoverability Index

  • Repository overview: README.md
  • Contribution process: CONTRIBUTING.md, docs/contribute.md
  • Local setup: docs/get-started.md, docs/local-development-guide.md
  • Architecture: docs/architecture-description.md
  • Engineering guidelines: docs/development-guidelines.md
  • Docker image builds (CI and local simulation): scripts/docker/README.md
  • Security and audits: docs/security.md, docs/audits.md
  • Package-specific agent rules: */AGENTS.md (contracts/, coordinator/, prover/, tracer/, ts-libs/sdk/, linea-besu/plugins/, transaction-exclusion-api/, e2e/)

Project Guidelines

Continuous Improvement

When a task requires a significant course correction (e.g., wrong architecture choice, misunderstood repository pattern, missed convention), propose an update to the relevant AGENTS.md.

For each proposal, include:

  • What failed or was ambiguous
  • Why it caused rework or risk
  • The concrete rule to add or modify
  • The correct scope (AGENTS.md at root vs package-level */AGENTS.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.
