agentcmd: Command for Claude Code

.claude/commands/cmd/generate-bug-spec.md

generate-bug-spec is a command for Claude Code from jnarowski/agentcmd. It costs 9 tokens per session (2,777 once invoked), scanned C, original, MIT.

A command that creates a bug-fix specification without changing the implementation. It documents reproduction steps, a suspected cause, ordered fix tasks, verification steps, file paths, commands, and complexity scores.

In plain words
What is it for?
Writing structured bug reports and fix plans in .agent/specs/todo/ for later implementation.
Why use it?
It gives developers a repeatable plan for investigating and fixing a bug before editing code.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: positional $N argument.

This is jnarowski/agentcmd's own configuration. It tells Claude Code how to work on agentcmd itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentcmd configures →

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 C, and why

generate-bug-spec scanned grade C with 1 finding 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 2mo 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Bug Fix Specification

Generate focused spec for bugs with reproduce → diagnose → fix → verify workflow. Creates spec at .agent/specs/todo/[id]-[bug]/spec.md with timestamp-based ID.

Variables

  • $param1: $1 (optional) - Bug context or description (infers from conversation if omitted)

Instructions

  • IMPORTANT: Use reasoning model - THINK HARD about reproduction, root cause, AND fix approach
  • IMPORTANT: This command ONLY generates spec - do NOT implement code or make changes beyond spec folder/file and index.json
  • Your ONLY file operations: create spec folder, write spec.md, update index.json - nothing else
  • Normalize bug name to kebab-case for folder name
  • Replace ALL <placeholders> with specific details
  • Formalize reproduction steps - make them precise and repeatable
  • Root Cause is iterative - start with hypothesis, update during investigation
  • Create detailed tasks with specific file paths and commands
  • Assign complexity (1-10) to EVERY task
  • Order tasks by dependencies
  • DO NOT include hour estimates - use complexity points only

Complexity Scale

Assign based on context window usage and cognitive load:

  • 1-2/10: Trivial - Single file, <50 lines, minimal context
  • 3-4/10: Simple - Few files, straightforward logic
  • 5-6/10: Moderate - Multiple related files, moderate context
  • 7-8/10: Complex - Cross-cutting change, high context
  • 9-10/10: Very complex - Architectural change, deep knowledge required

Key principle: Higher complexity = more context agent needs to load/understand

Workflow

  1. Determine Context:

    • If $param1 provided: Use as context
    • If $param1 empty: Infer from conversation history
  2. Generate Spec ID:

    • Generate timestamp-based ID in format YYMMDDHHmm using current local time
    • Example: November 13, 2025 at 2:22pm local → 2511131422
    • Read .agent/specs/index.json (will be updated in step 8)
  3. Generate Bug Name:

    • Generate concise kebab-case name from context (max 4 words)
    • Examples: "Memory leak in workflows" → "workflow-memory-leak", "Export crash" → "export-crash-fix"

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.
