analyze-first

analyze-first is a command for Claude Code from vibehat/claude-task-manager. It costs 0 tokens per session (216 once invoked), scanned A, original, MIT.

A command for examining the relevant parts of a codebase before deciding how to implement a change.

In plain words
What is it for?
Use it before planning a feature to map related files, understand the architecture, find reusable code, and decide whether to extend existing code or create something new.
Why use it?
It reduces guesses by documenting existing files, patterns, similar functionality, extension points, and integration dependencies first.

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

analyze-first 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 4d 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.

What it actually says

Analyze First - Codebase Analysis Before Planning

Use this command when you need to analyze the codebase before making any implementation decisions.

Usage: /analyze-first [feature or area to analyze]

Process

COMPLIANCE CONFIRMED: I will prioritize understanding existing architecture before suggesting changes.

ANALYSIS REQUIREMENTS:

  1. Map existing file structure relevant to: $ARGUMENTS
  2. Identify all related components, services, and utilities
  3. Document current patterns and conventions
  4. Note any duplicate or similar functionality
  5. Highlight extension points and architectural decisions

DELIVERABLES:

  • Complete file inventory with paths and purposes
  • Architecture diagram (text-based)
  • Reusability assessment for existing components
  • Integration points and dependencies
  • Recommendations for extension vs creation

VALIDATION CHECKPOINTS:

  • ✓ All relevant files identified and read
  • ✓ No assumptions about non-existent code
  • ✓ Current patterns documented
  • ✓ Reuse opportunities highlighted

This analysis will inform all subsequent planning and implementation decisions.

Changes

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.

analyze-first is a command published in the GitHub repository vibehat/claude-task-manager (21 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 216 tokens. 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.
