dogwood: Skill for Claude Code

.claude/skills/autoformalize-policies/SKILL.md

autoformalize-policies is a skill for Claude Code from dogwood-policy/dogwood. It costs 140 tokens per session (4,610 once invoked), scanned A, original, Apache-2.0.

A skill that turns access requirements written in everyday language into validated Dogwood policy files. Dogwood is a policy language for expressing and checking authorization rules.

In plain words
What is it for?
Use it for requirements such as allowing an action only when a condition holds, denying access after an event, or limiting actions within a time period.
Why use it?
It helps resolve ambiguous wording and catch policy errors before the resulting rule is used.

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

autoformalize-policies 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 12d 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.

Autoformalizing natural language into Dogwood policies

Your job: turn a natural-language authorization requirement into a Dogwood .dw policy that parses, validates against a schema, and means what the user actually intended. This is a formalization task — the hard part is not the syntax (that is fully documented; see Ground truth) but pinning down ambiguous intent and mapping it onto the right Dogwood construct.

Do not guess at intent when a requirement is underspecified, and do not return a policy you have not validated. Follow the loop below in order:

  1. Disambiguate the requirement (resolve every gap that changes the output).
  2. Formalize it into a .dw policy.
  3. Validate it — run it through the dogwood CLI and fix until it is clean. This step is mandatory (see Step 3); a policy that has not been validated is not a finished answer.
  4. Round-trip the intent and present the result.

The ground truth (read before authoring)

Dogwood's syntax and, crucially, its legality rules are precisely documented. Treat these as authoritative; do not invent syntax from memory. These paths are relative to this skill directory (.claude/skills/autoformalize-policies/); the guide lives in the dogwood-docs crate:

  • ../../../dogwood-docs/guide/02-policy-language.md — core policy syntax: permit/forbid, the (principal, action, resource) scope, when/unless, and the complete Cedar expression language (operators, literals, methods, has/like/is, sets/records, entity refs). 100% of the core syntax.
  • ../../../dogwood-docs/guide/04-temporal-expressions.md — the temporal { … } sublanguage: formerly/previous/since, windows, exists/tp, count/sum, predicates, and the acceptance rules (range restriction, conjunct ordering, tp-dependence). Read this in full before writing any history-dependent policy.
  • ../../../dogwood-docs/guide/02-policy-language.md (the "action schema" section) — the action schema and the context.input/context.output convention.
  • ../../../dogwood-docs/guide/03-event-schema.md — the event-schema DSL and decision vs history event kinds (needed only when customizing the default).
  • ../../../dogwood-docs/guide/05-information-providers.md — computed facts via Provider::Name(args) calls in an ordinary when { … }; see ../../../dogwood-docs/guide/10-provider-schema.md for declaring providers (providers.json, the Rhai contract).
  • ../../../dogwood-docs/guide/09-calling-macros.md — calling macros; and ../../../dogwood-docs/guide/06-macros.md — defining def cedar / def temporal (rarely needed; reach for it only for a genuinely reusable pattern).

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.
