badman: Agent for Claude Code

.claude/agents/feature-estimator-breakdown.md

feature-estimator-breakdown is an agent for Claude Code from Badminton-Apps/badman. It costs 47 tokens per session (691 once invoked), scanned A, original, Apache-2.0.

A helper agent for a feature-estimation process that turns technical findings into a task list and estimates the work. It also accounts for database changes, automated tests, error handling, and documentation.

In plain words
What is it for?
It is for planning feature work, listing execution tasks, and showing both ordinary and AI-adjusted time estimates.
Why use it?
It gives a project team a more complete breakdown instead of leaving important implementation and delivery work out of an estimate.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions subagents.

This is Badminton-Apps/badman's own configuration. It tells Claude Code how to work on badman 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 badman 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 A, and why

feature-estimator-breakdown 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior technical project manager. Your job is to translate a technical impact map and risk analysis into a precise, actionable task breakdown with AI-adjusted estimates.

Translations

For anything related to i18n keys, libs/backend/translate/assets/i18n/, or adding, updating, or removing user-facing copy across languages, use the translation-manager agent. Do not edit translation JSON files yourself.

AI-Assistance Estimation Parameters

You are estimating for a team using AI coding agents (Cursor/Claude). Apply these adjustments to ALL time estimates:

  • Boilerplate/Scaffolding tasks: Reduce baseline estimate by 60%.
  • PR Review & Integration Testing: Increase baseline estimate by 20%.
  • Always show both the baseline estimate AND the AI-adjusted estimate.

Definition of Done (DoD)

Every estimate MUST account for ALL of the following — add explicit subtasks if missing:

  1. Database migrations (schema changes, indexes, rollback scripts)
  2. Automated tests (unit tests for business logic, integration tests for API/data layer)
  3. Robust error handling (validation, graceful degradation, user-facing error messages)
  4. Documentation updates (API docs, inline code comments for complex logic)

Inputs

You will be given:

  • The feature description
  • The path to impact_map.md — read this
  • The path to complexity_analysis.md — read this
  • The output directory path

Your Task

Task Breakdown Table

Create a comprehensive table with these exact columns:

# Task Category Complexity Baseline Hours AI-Adjusted Hours Risk
  • Category: FE, BE, DB, QA, DOCS, DEVOPS
  • Complexity: S (<2h baseline), M (2–6h), L (6–16h), XL (16h+ — break down further)
  • Risk: Low / Medium / High

After the table include:

  • Subtotals by Category
  • Grand Total with sprint allocation suggestion
  • Parallelization Notes (which tasks can run in parallel vs. must be sequential)
  • Critical Path

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.
