aid-design-data-model

aid-design-data-model is a skill for Claude Code from AndreVianna/aid-methodology. It costs 138 tokens per session (937 once invoked), scanned A, original, MIT.

A planning aid for defining a data model: the entities in an application, how they relate, and what database changes adding them would require. It records the plan before a migration is written.

In plain words
What is it for?
Use it to plan entities, relationships, and the effects of introducing them on the database. It prepares a design for a separate build-and-migration step.
Why use it?
It helps clarify the shape and connections of stored data before implementation, reducing costly changes to the database later.

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

aid-design-data-model 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 26d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design Data Model (develop a design seed, resolve nothing)

Bind VERB=design, ARTIFACT=data-model -- the design stage in the contract's vocabulary -- then follow the shared contract at .aid/runtime/templates/design-lifecycle.md. This skill binds that contract and restates none of its rules. The seed it writes is .aid/design/data-model.md; realizing it into the built model and its migration is /aid-create-data-model's job, not this one's.

  • Boundary vs /aid-create-data-model: that skill builds the model and its migration from a ready seed; this one only develops the seed. Neither resolves anything on its own -- the user decides when a seed is ready to realize.
  • Not a numbered pipeline phase; does not route to /aid-execute.

State machine: INTAKE -> DESIGN -> VERIFY (loop) -> PRESENT [user decides] -> DONE, as design-lifecycle.md § Skill shape defines it. Print the [State: NAME] -- {purpose} entry line on each state.

State: INTAKE

  1. Require a subject. Empty argument -> ask one bootstrapping question ("What data model do you want to design -- its entities, relationships, and migration impact?") and wait.
  2. Allocate through the Work Initiation Gate exactly as the contract's Allocation rule requires (.agents/skills/aid-design/SKILL.md INTAKE step 4 is the shape), with initiator: aid-design-data-model. phase is not driven.
  3. Acquire .aid/design/ per the contract, then read .aid/design/data-model.md if a prior seed exists -- re-invocation iterates it rather than starting over.
  4. Classify complexity for the aid-architect dispatch (verifier tier >= producer).

Advance: DESIGN.

State: DESIGN

Dispatch aid-architect (clean context, tiered) to write or iterate .aid/design/data-model.md in the seed shape the contract fixes (design-seed.md; feature-002 §4), grounded in .aid/knowledge/ and the project source plus any seed read in INTAKE. What this artifact's seed must settle: its entities, their relationships, and the migration impact of introducing them; its ## Destination names where the built model and its migration land. Never writes .aid/knowledge/ and never writes production code -- the design invariant (design-lifecycle.md).

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.
