project-planner

project-planner is a skill for Claude Code, Codex from amanning3390/hermeshub. It costs 40 tokens per session (480 once invoked), scanned A, original, MIT.

A project-planning tool that turns a goal into milestones, tasks, dependencies, effort estimates, and a timeline. A milestone is a major delivery point, while a dependency is work that must happen first.

In plain words
What is it for?
Use it to break down projects, plan sprints and roadmaps, estimate tasks, identify the critical path, track progress, and save the plan as a Markdown file.
Why use it?
It helps expose the order and size of the work, reducing plans that overlook prerequisites or assume too much work can happen at once.

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

project-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 9d 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.

What it actually says

Project Planner

Structured project planning with task decomposition and tracking.

When to Use

  • User describes a project and needs a plan
  • User wants to break down work into tasks
  • User needs timeline estimates
  • User wants to track progress against milestones

Procedure

  1. Gather project scope and constraints
  2. Decompose into milestones (major deliverables)
  3. Break milestones into tasks (actionable items)
  4. Identify dependencies between tasks
  5. Estimate effort for each task
  6. Generate timeline with critical path
  7. Save plan to workspace as markdown

Plan Format

# Project: [Name]
**Goal:** [One sentence]
**Timeline:** [Start] → [End]

## Milestones
### M1: [Milestone Name] (Due: [date])
- [ ] Task 1 (Est: 2h, Depends: none)
- [ ] Task 2 (Est: 4h, Depends: Task 1)

### M2: [Milestone Name] (Due: [date])
- [ ] Task 3 (Est: 8h, Depends: M1)

Estimation Guidelines

  • Small task: 1-2 hours
  • Medium task: 4-8 hours
  • Large task: 2-3 days (should be broken down)
  • Add 20% buffer for unknowns

Pitfalls

  • Over-optimistic estimates — multiply initial guess by 1.5
  • Ignoring dependencies creates phantom parallelism
  • Plans without review points drift silently
  • Too granular = overhead; too coarse = no visibility

Verification

  • Every task has an owner and estimate
  • Dependencies form a DAG (no cycles)
  • Critical path is identified
  • Buffer exists for high-risk items
Changes

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.
