At a glance

Creates and updates local plan documents in .cursor/plans with required timestamp and package version metadata in both file body and filename.

  • SKILL.md covers Scope, Required in-file sections, Prune stale plans before saving and Required location, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Fantasia Plan Documents is an agent skill from vishiri/fantasia-archive. Creates and updates local plan documents in .cursor/plans with required timestamp and package version metadata in both file body and filename. Before saving a new plan, deletes existing plan files whose last modified time is more than 30 days old.

Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A world-builder's best friend! The licence is GPL-3.0.

Example prompts

  • “Use the fantasia-plan-documents skill to create and updates local plan documents in .cursor/plans with required timestamp and package version…”
  • “/fantasia-plan-documents”

What it can do on your machine

Read from SKILL.md and the folder at commit 26d4648. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fantasia Plan Documents loads about 436 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 145 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~436

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Creates and updates local plan documents in .cursor/plans with required timestamp and package version metadata in both file body and filename. Before saving a new plan, deletes existing plan files whose last modified time is more than 30 days old.

Plan documents (.cursor/plans)

Scope

Planning artifacts: rollout inventories, checklists, migration trackers, etc.

Resolve open product/UX/scope decisions per clarify-before-assume.mdc before saving plan.

Required in-file sections

After metadata (Created at, Project version), include Uncertainty gate:

  • Product/UX/scope gaps resolved via AskQuestion or explicit user answers before implementation
  • Do not guess, assume, or imply unstated behavior
  • No implementation steps that depend on unstated product choices

Prune stale plans before saving

  • List .cursor/plans/ before new plan
  • Delete files with mtime >30 days old
  • Skip if folder missing/empty

Required location

  • .cursor/plans/ — create if missing
  • No top-level docs/ for plans unless user requests elsewhere

Required filename format

Topic + version + timestamp YYYY-MM-DD-HH-mm-ss.

Example: feature-x-plan_v2.1.0_2026-03-30-20-10-39.plan.md

Required in-file metadata

  • Created at: YYYY-MM-DD-HH-mm-ss
  • Project version: <package.json version>

Version source

Read package.json — same value in filename + body.

Notes

  • Local temporary workspace; may be gitignored
  • Drafts elsewhere → move into .cursor/plans/ + normalize metadata
