analyzing-projects

A systematic method for exploring an unfamiliar codebase and understanding how its parts fit together.

In plain words
What is it for?
Use it when joining a project, investigating a feature, mapping dependencies, recognizing architecture patterns, or assessing tests and technical debt.
Why use it?
It reduces the time spent guessing where an application starts, how data moves, which modules depend on each other, and where quality problems may exist.

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

analyzing-projects 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 2d 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.

Analyzing Projects

Systematic approaches to understanding codebases, identifying patterns, and mapping system architecture.

When to Use This Skill

  • Onboarding to a new codebase
  • Understanding unfamiliar code before making changes
  • Investigating how features are implemented
  • Mapping dependencies between modules
  • Identifying architectural patterns in use

Core Analysis Framework

The 5-Layer Discovery Process

Layer 1: Surface Scan
  └─ Entry points, config files, directory structure

Layer 2: Dependency Mapping
  └─ Package managers, imports, module relationships

Layer 3: Architecture Recognition
  └─ Patterns (MVC, hexagonal, microservices)

Layer 4: Flow Tracing
  └─ Request paths, data flow, state management

Layer 5: Quality Assessment
  └─ Test coverage, code health, technical debt

Phase 1: Surface Scan

Entry Point Discovery

Start by identifying how the application launches:

  1. Look for standard entry files:

    • main.*, index.*, app.*, server.*
    • cmd/ directory (Go)
    • src/main/ (Java)
    • bin/ scripts
  2. Check configuration files:

    • package.json (scripts.start, main)
    • Makefile, Taskfile
    • Docker/Compose files
    • CI/CD configs (.github/workflows/)
  3. Map directory structure:

    Quick heuristics:
    ├── src/           → Source code
    ├── lib/           → Internal libraries
    ├── pkg/           → Public packages (Go)
    ├── internal/      → Private packages (Go)
    ├── tests/         → Test files
    ├── docs/          → Documentation
    ├── scripts/       → Build/deploy scripts
    └── config/        → Configuration
    

Initial Questions to Answer

  • What language(s) and framework(s)?
  • What's the build system?
  • How is the app deployed?
  • Where are the main entry points?

Phase 2: Dependency Mapping

Package Manager Analysis

File Ecosystem Key Sections
package.json Node.js dependencies, devDependencies
requirements.txt / pyproject.toml Python direct dependencies
go.mod Go require blocks
Cargo.toml Rust dependencies
pom.xml / build.gradle Java dependencies

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.

analyzing-projects is a skill published in the GitHub repository CloudAI-X/opencode-workflow (274 stars, last pushed 7mo ago), licensed MIT. It adds 37 tokens to every session and 1,712 once invoked, about $0.0002 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 2026-08-30.
