deep-analyzer

deep-analyzer is a skill for Claude Code, Codex from dayvisonassis/sdd-skills. It costs 85 tokens per session (4,340 once invoked), scanned A, original, MIT.

A code-analysis tool that examines every listed part of a software project in detail, including how it works, connects to other parts, and can fail.

In plain words
What is it for?
Use it to document routes, services, data models, external calls, error paths, and other units after an architecture analysis has been completed.
Why use it?
It turns a broad architecture report into a closer explanation of implementation details, data movement, dependencies, and failure cases.

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

deep-analyzer 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 7d 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.

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.
  • For every data model / entity: documents every field (name, type, constraints, nullable, default, indexed), all relationships, all query patterns that use this model, and data integrity rules.
  • For every component (frontend): documents the component API (inputs, outputs, events), template structure, data bindings, lifecycle hooks, service dependencies, state management patterns, and rendering conditions.
  • For every repository / data-access layer: documents every query, its parameters, its return shape, whether it uses transactions, and its N+1 risk.
  • Identifies every failure mode: what happens when each external dependency is unavailable, when validation fails, when a database query returns unexpected results.
  • Maps every configuration dependency: which env vars or feature flags change the behavior of each unit.
  • Documents test gaps: what is NOT tested and what the risk is.
  • Calculates a refactoring complexity score per unit with justification.

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.

deep-analyzer is a skill published in the GitHub repository dayvisonassis/sdd-skills (1 stars, last pushed 11d ago), licensed MIT. It adds 85 tokens to every session and 4,340 once invoked, about $0.0004 per session on Opus 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 2026-08-31.
