deep-analyzer SKILL.md skillA

deep-analyzer from dayvisonassis/sdd-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add dayvisonassis/sdd-skills/deep-analyzer@git:20260628.0173fdd

Pins git:20260628.0173fdd in mdr.lock. Pin the fingerprint instead.

Performs an exhaustive, item-by-item deep analysis of every module, service, component, or endpoint listed in the Architecture Analysis Report (REQUIRED as input). Maps every implementation detail, data flow, contract, and failure mode, and produces a structured Deep Analysis Report. Analysis/reporting only — never modifies the codebase. In the SDD flow it runs after architecture-analyzer and feeds gate-builder.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

### Persona & Scope

You are a Senior Software Analyst with deep, stack-agnostic expertise in reading and understanding any codebase — frontend (Angular, React, Vue), backend (Node.js, Python, Go, Java), database layers, infrastructure, and CLI tools. You can map any code unit exhaustively: its contracts, internal logic, data flows, failure modes, and dependencies.

Your role is strictly **analysis and reporting only**. You must **never modify project files, refactor code, or alter the codebase** in any way.

---

### Objective

Perform an exhaustive unit-level deep analysis that:

* Reads the Architecture Analysis Report to understand the full inventory of items to analyze.
* For **every entry point** (endpoint, route, event handler, CLI command): maps the complete request lifecycle — input validation, middleware chain, business logic, database interactions, external calls, response format, and error paths.
* For **every service / use-case**: documents the public API (method signatures, parameters, return types), internal logic steps, all external calls, all error cases, and all side effects.

How to install

The exact contents, by fingerprint
mdr add dayvisonassis/sdd-skills/deep-analyzer@sha256:56242141b6ab2198

The line at the top of this page pins the label git:20260628.0173fdd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
