What is docs-to-types?

An architecture step that turns agreed documentation into typed code structure, including domain values, valid states, interfaces, errors, and module boundaries. It is intended for defining the framework around behavior, not implementing the behavior itself.

Use it after clarifying domain notes and architecture decisions, before implementing workflows, to define types, adapters, error handling, and dependency direction.

Important rules written only in documents can be forgotten or applied inconsistently. Types and module boundaries make those rules visible to the compiler and the team.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.00868
Opus 5.5	$0.00025	$0.00347
Sonnet 5.5	$0.00012	$0.00174
Haiku 4.5	$0.00006	$0.00087

Security

Grade A, and why

docs-to-types 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 2mo 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.

Docs to Types

Upfront architecture skill for converting clarified prose into typed architecture. If the team knows a durable domain or architecture fact, the type system and module graph should know it too.

Not for general grilling, refactoring review, or the first TDD slice. CONTEXT.md, ADRs, and grill notes are source material, not the final harness.

Prime directive

Do not implement business behavior. Compress approved context into the whole intended typed architecture:

canonical domain types, schemas, brands, and invariants
discriminated unions/state models that rule out invalid states
smart constructors/parsers for values entering from system edges
service/interface seams using project conventions
typed result/error families and error translation boundaries
production/test adapter slots
composition/layer/module topology using project conventions
production and test call stacks
dependency-direction checks where practical

Do not create business workflows, real persistence/network logic, product behavior, after-the-fact refactors, generic mutation/outcome frameworks, or fake production logic pretending to be complete.

Read first

AGENTS.md and project coding rules
CONTEXT-MAP.md, if present
relevant CONTEXT.md files
relevant docs/adr/*
approved grill-with-docs notes/specs
existing source near the target area

If there are no context docs/ADRs and no approved grill-with-docs output, stop and recommend grill-with-docs.

Workflow

1. Extract architecture facts

Before editing, produce a fact table:

| Fact                                        | Source     | Code artifact         | Confidence |
| ------------------------------------------- | ---------- | --------------------- | ---------- |
| Link Catalog is the application-facing seam | CONTEXT.md | `LinkCatalog` service | high       |

Include domain names, ownership boundaries, dependency direction, call stacks, adapter choices, runtime constraints, typed errors, and infrastructure that must stay behind adapters.

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.

docs-to-types is a skill published in the GitHub repository modernweb-dev/rocket (395 stars, last pushed 8d ago), licensed MIT. It adds 62 tokens to every session and 868 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
