A personal collection of agent skills, workflow references, delivery playbooks, and focused audit checklists for AI coding agents.

The Markdown files in [ skills/](/metacircu1ar/skill_vault/blob/main/skills) document reusable workflows for advising, batch changes, code review, deep research, goal-driven execution, verifier generation, localization, simplification, and testable frontends.

[ skills/product-delivery-skills/](/metacircu1ar/skill_vault/blob/main/skills/product-delivery-skills) contains four self-contained, installable skills:

| Skill | Purpose |
|---|---|
`product-implementation-planner` |

`product-plan-compiler`

`parallel-plan-implementation`

`phase-commit-reviewer`

The default delivery sequence is `product-implementation-planner`

→ `product-plan-compiler`

→ `parallel-plan-implementation`

→ `phase-commit-reviewer`

.

Each product-delivery skill includes its supporting references, templates, schemas, scripts, and a dedicated README.

[ skills/audit/](/metacircu1ar/skill_vault/blob/main/skills/audit) contains focused audit playbooks. Each one is intended to produce concrete findings with file paths, line numbers, impact, and suggested fixes.

| Skill | Purpose |
|---|---|
`audit-input-validation` |

`audit-auth-and-access-control`

`audit-secrets-and-config`

`audit-rate-limiting`

`audit-cors`

`audit-database-performance`

`audit-resilience-and-observability`

`audit-asset-pipeline`

`audit-type-safety`

`security-review`

`ios-prelaunch-checklist`
