freddie: Skill for Claude Code

.agents/skills/freddie-doc-standards/SKILL.md

freddie-doc-standards is a skill for Claude Code, Codex from AnEntrypoint/freddie. It costs 82 tokens per session (1,304 once invoked), scanned A, original, MIT.

A set of rules for writing and organizing documentation in the Freddie repository. It distinguishes learning guides from reference material and covers document placement, structure, length limits, and validation.

In plain words
What is it for?
Use it to write, move, review, or audit Markdown, code comments, and API documentation, and to decide where repository notes and incident reports belong.
Why use it?
It prevents documentation from becoming misplaced, repetitive, too detailed, or hard to follow. It also helps resolve checks that report documentation-rule violations.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is AnEntrypoint/freddie's own configuration. It tells Claude Code and Codex how to work on freddie itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything freddie configures →

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

freddie-doc-standards 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 3d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Applying the Freddie Documentation Standard

The documentation rules live in docs/AGENTS.md. This workflow covers placement, corpus audits, budgets, and validation across Markdown, JSDoc, and code comments. It is guidance, not a script; use freddie-prose-standard for required coverage and editorial judgment, and never treat length alone as a defect.

Sources of truth (read, don't re-summarize)

  • docs/AGENTS.md — hierarchy, tutorial/reference forms, taxonomy, budgets, and slop checklist.
  • .agents/notes/README.md — when a decision earns an Agent Note, how to file it, and what goes inside one (the header block, per-lifecycle skeleton, and Alternatives-considered mandate, gated by verify-agent-note-format); docs/postmortem/README.md — when an incident earns a postmortem.
  • Root AGENTS.md — the standing orders whose budget discipline this skill protects.
  • Archived Agent Notes — frozen historical snapshots excluded from editorial maintenance and evolving documentation gates.

Review structure before prose

Apply the standard's authoring order to every human-facing document in scope. Do not apply this structural pass to Agent Notes. Classify a postmortem as a reference scoped to one incident; preserve its required chronological evidence without treating chronology as a teaching sequence.

  1. Locate the document in the repository and navigation trees. State its own subject and identify its direct children.
  2. Set the permitted level of detail. Keep full detail about the document's subject, summarize direct children by purpose, responsibility, and high-level behavior, and move deeper explanations to their owning descendants with links. Treat test infrastructure as descendant-owned unless it is the document's subject.
  3. Classify the document from its intended use, not its path or title. A tutorial must lead through ordered work to an observable outcome; a reference must support lookup within an explicit scope without requiring sequential reading.
  4. For a tutorial, privately classify the starting reader and concepts as beginner, intermediate, or advanced. Trace each concept to its prerequisites, reorder premature material, and move optional advanced detail to a later tutorial or reference.
  5. Split substantial mixed forms. Put a small secondary form in a clearly labeled section.

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.
