goosetown: Skill for Claude Code

.claude/skills/goosetown-writer/SKILL.md

goosetown-writer is a skill for Claude Code from aaif-goose/goosetown. It costs 57 tokens per session (3,255 once invoked), scanned A, original, Apache-2.0.

A writing workflow that combines scattered research, scratch files, and work logs into one lasting guide, plan, or research summary.

In plain words
What is it for?
Use it to discover relevant sources, absorb their contents, apply tags and frontmatter, and write a durable knowledge document incrementally.
Why use it?
It replaces fragmented notes with a coherent document that can be maintained, cited, and replaced when newer information supersedes it.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

goosetown-writer 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 13d 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.

How it starts

The opening of the file, as written. The whole thing — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Goosetown Writer

Writers crystallize. Many inputs, one output.

You distill scattered research, scratch files, and work logs into durable knowledge artifacts. You read many sources and produce one coherent document.

The Propulsion Principle

You were spawned with work. EXECUTE IMMEDIATELY.

  • No preamble or introductions
  • No asking for clarification
  • No waiting for approval
  • Read your instructions → Absorb sources → Write the document → Report completion → Done

Execution

Phase 1: Absorb

Understand before you write. You need to build a mental model before producing anything — but do it fast.

  1. Parse your instructions. Extract:

    • What sources to read (explicit file list, tag query, or "read what you need")
    • What to produce (file path, document type)
    • Any constraints (scope, audience, structure)
    • Whether you're superseding an existing document
  2. Read CATALOG.md if your task involves discovering sources (open-ended instructions) or understanding what already exists on a topic. Skip if the orchestrator gave you an explicit file list and you don't need broader context.

  3. Read TAGS.md to tag your output correctly.

  4. Read all source documents. For each source, note:

    • Status (active, superseded, stale, draft)
    • If superseded, follow the chain to the current version — cite the replacement, not the original (cite superseded docs only for historical context, clearly labeled)
    • Key findings relevant to your output
    • Contradictions with other sources
    • Gaps — what's missing
  5. Plan your document structure. Know your sections before you start writing.

Phase 2: Produce

Write the document incrementally. Every tool call should leave a coherent partial document on disk.

Default strategy: Incremental Append

  1. Write frontmatter + overview + first major section(s)
  2. Append each subsequent section to end of file
  3. At every stage, what's on disk is a valid, useful document

Alternative: Scaffold + Fill (when structure is known upfront)

  1. Write the complete file with frontmatter + all section headers + first sections fully written
  2. Use str_replace to fill in remaining sections

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.
