foundation: Skill for Cursor

.cursor/skills/create-plan/SKILL.md

create-plan is a skill for Cursor from markmhendrickson/foundation. It costs 25 tokens per session (686 once invoked), scanned A, a copy of create-plan, MIT.

A workflow for creating a new plan as a Neotoma record. It collects the plan's goals, scope, success measures, and status, then can link it to related project records.

In plain words
What is it for?
Use it to create plans, check that their summary matches the intended work, connect them to objectives or releases, and optionally rebuild the plans mirror.
Why use it?
It turns an informal idea into a structured plan with clear boundaries and measurable completion criteria.

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

create-plan 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 1mo 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.

Create New Plan

Create a new plan entity in Neotoma with title = {{input:title}}.

Follow the complete workflow in foundation/development/plan_workflow.md. Configuration is read from foundation-config.yaml.

This workflow can also be triggered automatically via .cursor/rules/plan_detection.mdc when you mention planning-related patterns in natural language (e.g., "create plan", "new plan"). Both paths execute the same workflow.

Workflow Overview

Implements Checkpoint 0 of the plan creation workflow:

  1. Collect required plan fields from the user
  2. Run alignment check (summary → user confirms)
  3. Store plan as a Neotoma plan entity
  4. Create relationships to related entities
  5. Optionally rebuild the neotoma-plans mirror

Tasks

  1. Collect required fields:

    Ask the user for any missing required fields:

    • title — Short, imperative name
    • description — Problem being solved and why it matters
    • scope — What is explicitly in scope
    • out_of_scope — What is explicitly out of scope
    • success_criteria — Measurable conditions for completion
    • status — Default to draft

    Optional fields to offer (collect if relevant):

    • priority (P0/P1/P2/P3)
    • phase
    • target_release
    • deliverables
    • dependencies (canonical names of plans this plan requires)
    • testing_notes
    • observability_notes
  2. Alignment check:

    After collecting fields, produce a concise summary:

    • Problem it solves and why it exists
    • What is explicitly in scope and out of scope
    • Critical constraints or invariants

    Ask: "Does this accurately capture what you want this plan to do?"

    Incorporate corrections and re-summarize if changes are substantial. Do not proceed until the user confirms.

  3. Store the plan:

    Use store or submit_entity with:

    • entity_type: plan
    • All collected fields as snapshot fields
  4. Create relationships (if relevant entities are mentioned or known):

    • REFERS_TO for objectives, releases, or parent plans
    • DEPENDS_ON for plans this plan requires
    • INFORMED_BY for issues, feedback, or research

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.
