What it does

To Spec is an agent skill from rengwu/wayfinder-maps. Turn the current conversation into a spec, saved to .plan/ — no interview, just synthesis of what you've already discussed.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering User stories. The repository describes itself as: Planetary visualization tool for /wayfinder maps. The licence is MIT.

When your agent uses it

  • Tasks that involve User stories

Example prompts

  • “/to-spec”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Explore the repo to understand the current state of the codebase, if you haven't already. If a CONTEXT.md glossary exists at the repo…
  2. Sketch out the seams at which you're going to test the feature — the public interfaces where behaviour can be observed without reaching…

What it can do on your machine

Read from SKILL.md and the folder at commit c252110. 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

To Spec loads about 813 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 482 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~813

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.

Turn the current conversation into a spec, saved to `.plan/` — no interview, just synthesis of what you've already discussed.
disable-model-invocation
true

This skill takes the current conversation context and codebase understanding and produces a spec (you may know this document as a PRD). Do NOT interview the user — just synthesize what you already know.

Process

  1. Explore the repo to understand the current state of the codebase, if you haven't already. If a CONTEXT.md glossary exists at the repo root, use its vocabulary throughout the spec; respect any ADRs in docs/adr/ in the area you're touching. If neither exists, proceed silently.

  2. Sketch out the seams at which you're going to test the feature — the public interfaces where behaviour can be observed without reaching inside. Existing seams should be preferred to new ones. Use the highest seam possible. If new seams are needed, propose them at the highest point you can. The fewer seams across the codebase, the better - the ideal number is one.

Check with the user that these seams match their expectations.

  1. Write the spec using the template below, then save it to .plan/<slug>/spec.md, where <slug> is a short kebab-case name for the work (reuse the directory if one already exists for this effort). Create the directory if needed — .plan/ is committed to version control; it is the project's shared planning memory. Tell the user the path.
<spec-template>

Problem Statement

The problem that the user is facing, from the user's perspective.

Solution

The solution to the problem, from the user's perspective.

User Stories

A LONG, numbered list of user stories. Each user story should be in the format of:

  1. As an <actor>, I want a <feature>, so that <benefit>
<user-story-example>
1. As a mobile bank customer, I want to see balance on my accounts, so that I can make better informed decisions about my spending
</user-story-example>

This list of user stories should be extremely extensive and cover all aspects of the feature.

Implementation Decisions

A list of implementation decisions that were made. This can include:

  • The modules that will be built/modified
  • The interfaces of those modules that will be modified
  • Technical clarifications from the developer
  • Architectural decisions
  • Schema changes
  • API contracts
  • Specific interactions

Do NOT include specific file paths or code snippets. They may end up being outdated very quickly.

Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it within the relevant decision and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.

Testing Decisions

A list of testing decisions that were made. Include:

  • A description of what makes a good test (only test external behavior, not implementation details)
  • Which modules will be tested
  • Prior art for the tests (i.e. similar types of tests in the codebase)

Out of Scope

A description of the things that are out of scope for this spec.

Further Notes

Any further notes about the feature.
