PlanExe: Instructions file for Codex

AGENTS.md

PlanExe AGENTS.md is an instructions file for Codex, OpenCode from PlanExeOrg/PlanExe. It costs 1,637 tokens per session, scanned A, original, MIT.

Repository instructions for PlanExe, a system made of services and shared packages that runs planning pipelines through web interfaces, workers, databases, and MCP connections. They map the architecture and define compatibility rules for APIs, database models, and task identifiers.

In plain words
What is it for?
Use them to modify PlanExe services, preserve shared contracts, update workers or interfaces, and verify changes across the system.
Why use it?
They help developers change one service without breaking shared data models, existing API clients, or saved planning workflows.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; built for openclaw.

This is PlanExeOrg/PlanExe's own configuration. It tells Codex and OpenCode how to work on PlanExe 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 PlanExe 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

PlanExe AGENTS.md scanned grade A with 1 finding 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 2mo 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.

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PlanExe agent instructions

Scope: repo-level guardrails for PlanExe services and shared packages. Always check the package-level AGENTS.md for file-specific rules (use rg --files -g 'AGENTS.md' if you are unsure).

Repo architecture map

  • database_api: shared SQLAlchemy models for DB-backed services.
  • worker_plan/worker_plan_api: shared API types/helpers (must stay lightweight).
  • worker_plan: FastAPI service that runs the pipeline.
  • frontend_multi_user: Flask UI (hosted mode) + Postgres.
  • worker_plan_database: DB-backed worker that polls tasks.
  • mcp_cloud: MCP stdio server + HTTP wrapper; primary cloud deployment, secondary Docker setup for advanced users, tertiary venv workflow for developers; bridges MCP tools to PlanExe DB/worker_plan.

Shared contracts

  • Keep worker_plan HTTP endpoints and response shapes backward compatible.
  • Preserve shared SQLAlchemy models in database_api (nullable defaults for new columns).
  • Run directory naming defaults live in worker_plan/worker_plan_api/generate_run_id.py. Verify in code before changing run-id formats.
  • Keep prompt catalog UUIDs stable when used as defaults; they live in worker_plan/worker_plan_api/prompt/data/*.jsonl.

Hard rules (agent safety)

  • Never commit directly to main. Always create a feature branch (e.g. feat/short-description, fix/short-description) and commit there. Push the branch and open a PR so CI can verify the changes.
  • Do not add real API keys or passwords to .env, .env.*, or any llm_config/*.json file.
  • Treat track_activity.jsonl as sensitive (may contain API keys/tokens). Never expose it to end users. Store track_activity.jsonl in PlanItem.run_track_activity_jsonl and keep it out of downloadable zips at artifact creation time. Legacy snapshots may be sanitized at download time, but new snapshots should be served directly without unzip/recompress.
  • Shared packages (database_api, worker_plan_api) must not import service apps (frontend_*, worker_plan_database, worker_plan.app).
  • If a service needs shared logic, move it into a shared package rather than importing across service boundaries.

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.
