29-ia.md，逐块说明
bank-app 还没有 29-ia.md。以下是 SKILL.md 所述该分文件包含的块。
## 1 · AI ports
One row per port: kind, what it asks, what it returns, the "could not decide" value, the review state
## 2 · Provider and models
Provider, model and options per port, and whether inherited
## 3 · Prompts and output
Per LLM port: resources, variables, answer type, closed fields, every unusable answer. Per search: threshold and its basis, result ceiling
## 4 · Data sent
Per field: sent or not, in which form, why; the receiver and its agreement
## 5 · Vector store
Store, embedding model, dimensions, distance, item id, every writer and its re-index path — none without a store
## 6 · Failure and retry
Per port: timeout, retrying layer, attempts; the failure table; project-wide pieces NEW or REUSE
## 7 · Observability
Metric names and the alarm each exists for; content logging off
## 8 · Test cases
Every case, by level
## 9 · Requirements to other partials
Migration, re-index trigger, ingestion job, review state
## 10 · Declared dependencies
BOM and starters
## 11 · Configuration
Every property, its value, its owner
## 12 · Deferred
Same shape as every partial. none when nothing was deferred
## Compose services
The postgres image row for a store, or none
## Design patterns
The adapter over each port, with its classes — step 10b
它读什么、写什么、拒绝什么
skill 自己的契约，取自 SKILL.md，保留原文。
Class
design — the territory is skill_classes.design in @.claude/schemas/extensions.json, and ArchHook.java guard enforces it. Writes inside the use case folder and nothing else.
Reads
docs/use-cases/UC-NNN-<slug>/00-use-case.md (mandatory), 10-domain.md (mandatory), 30-rest.md, 25-messaging.md, 35-jobs.md, 32-security.md (when present), the Components tables and 29-ai.md of earlier cases, pom.xml, docker-compose.yml, the active blueprint's packages.map, the Initializr's metadata, @.claude/rules/ai.md, @.claude/rules/http-client.md, @.claude/rules/error-handling.md, @.claude/rules/personal-data.md, @.claude/rules/secrets.md, @.claude/rules/observability.md, @.claude/rules/architecture-ddd.md, @.claude/skills/docker-architect/references/compose-service-decision.md, and this skill's references/.
Writes
docs/use-cases/UC-NNN-<slug>/29-ai.md. Nothing else.
Owns
the provider and the model and options of each AI port, the prompt resources and their variables, the answer type and what each unusable answer becomes, the fields sent to the provider, the store, its embedding model and the list of writers that must re-index, the timeout and the retrying layer of each AI port, the translation of provider failures, AI metrics, AI dependencies and configuration, and the postgres image row a store needs.
Does not decide
the port, its domain types or the review state (10-domain.md), the trigger and its deadline (00-use-case.md, 30-rest.md), a re-index trigger or an ingestion job (25-messaging.md, 35-jobs.md), the migration's final form (20-persistence.md), or the tests (40-tests.md). Does not write Java, prompts, pom.xml, application.yml or docker-compose.yml — the executor and docker-architect do, from this partial. Doesn't touch .claude/rules/**.

guard 如何处理它
design 是这个 skill 的类。ArchHook 在 skill 被调用时开启一个阶段，并按该类的领地检查每次写入。右侧文字是 hook 自己的输出。
design 类的 write_allow
- ✓
docs/use-cases/UC-*/** - ✓
docs/use-cases/BACKLOG.md src/**：迁移和类归执行器docker-compose.yml：另一个类的文件已批准的用例：其 spec 已冻结
拒绝以退出码 2 结束，消息回到模型。
PreToolUse Skill(ai-architect) audit call exit 0 guard call exit 0 # a skill of another class replaces the phase # write_allow: docs/use-cases/UC-*/**, docs/use-cases/BACKLOG.md
PreToolUse Write(docs/use-cases/UC-005-record-kyc-verdict/29-ia.md) guard write exit 0 PostToolUse audit file exit 0
PreToolUse Write(docker-compose.yml) guard write exit 2 ❌ `ai-architect` is class `design` — docker-compose.yml is outside its territory. write_allow: docs/use-cases/UC-*/**, docs/use-cases/BACKLOG.md Put the content in the spec as a code block, or finish the run and invoke the skill that owns this path. If the path is legitimately this skill's, widen skill_classes.design in .claude/schemas/extensions.json — retrying will not help.
# UC-005-record-kyc-verdict-spec.md: status: approved PreToolUse Edit(docs/use-cases/UC-005-record-kyc-verdict/29-ia.md) guard write exit 2 ❌ UC-005-record-kyc-verdict is approved — its specs are immutable. Record the change in the new use case's "Impact on approved use cases" section, and the one-line entry in UC-005-record-kyc-verdict/CHANGELOG.md, which stays writable.
它在轨道上的位置
每张卡片是 /new-feature 的一步；箭头带着一步交给下一步的分文件。虚线的步骤仅在用例需要时运行。
/new-feature orchestrator · opus/new-feature-implement 之后谁读这份分文件批准之后，/new-feature-implement 让执行器构建代码。spec 按引用整合，与分文件不一致时以 spec 为准；分文件按章节读取，用于细节。
