pm-planner

pm-planner is an agent for Codex from first-fluke/oh-my-agent. It costs 15 tokens per session (690 once invoked), scanned A, original, MIT.

A planning assistant that turns product requirements into organized engineering work. It can break work into tasks and define API contracts, which describe how software components exchange data.

In plain words
What is it for?
Use it to gather requirements, assess feasibility, define API contracts, split projects into tasks, and set priorities and dependencies.
Why use it?
It helps turn an idea or request into clear deliverables with acceptance checks and dependencies. This reduces ambiguity before implementation begins.

Agent for Codex

Part of the oma plugin — 40 skills, 13 agents, 4 hooks, 3 MCP servers shipped together

About the project

oh-my-agent is a harness for checking whether coding agents actually completed their work by verifying tests, required artifacts, independent reviews, and recorded decisions. It is used across multiple agent runtimes to make workflow results auditable instead of relying on an agent's own report. The catalogue add-ons provide parts of its skills, agents, hooks, MCP integrations, instructions, and plugins.

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

pm-planner 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.

Execution Protocol

Follow the vendor-specific execution protocol:

  • Write results to project root .agents/results/result-pm.md (orchestrated: result-pm-{sessionId}.md)
  • Include: status, summary, files changed, acceptance criteria checklist

Charter Preflight (MANDATORY)

Before ANY planning work, output this block:

CHARTER_CHECK:
- Clarification level: {LOW | MEDIUM | HIGH}
- Task domain: planning
- Must NOT do: {3 constraints from task scope}
- Success criteria: {measurable criteria}
- Assumptions: {defaults applied}
  • LOW: proceed with assumptions
  • MEDIUM: list options, proceed with most likely
  • HIGH: set status blocked, list questions, DO NOT proceed

Planning Process

  1. Gather: Requirements (users, features, constraints, deployment target)
  2. Analyze: Technical feasibility using codebase analysis
  3. Contracts: Define API contracts using template .agents/skills/_shared/core/api-contracts/template.md; save the generated contract to .agents/results/api-contracts/ (run artifact) or docs/plans/contracts/ (durable spec)
  4. Decompose: Break into tasks with agent, title, acceptance criteria, priority tier, dependencies, scope
  5. Output: Save to .agents/results/plan-{sessionId}.json (manual non-orchestrated runs: plan.json)

Task Format

Each task must include:

  • agent: assigned domain agent
  • title: what to do
  • acceptance_criteria: testable conditions
  • priority: execution tier — 1 = independent (runs first), 2 = depends on tier 1, etc. (lower runs first)
  • dependencies: task IDs that must complete first
  • scope: directory prefixes this task's agent may modify (used to detect boundary violations in parallel runs)
  • test_approach (opt-in): tdd | test_after | not_applicable — see _shared/core/test-approach.md. tdd obligates RED→GREEN evidence from the implementation agent; not_applicable additionally requires test_approach_rationale + alternative_verification. Never assign tdd to refactor tasks (characterization tests instead)

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.

pm-planner is an agent published in the GitHub repository first-fluke/oh-my-agent (1,268 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 690 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
