issue-estimator

An estimation agent that turns product requirements, research, and project plans into small development tasks with effort estimates and completion conditions.

In plain words
What is it for?
It helps prepare sprint-board issues with story points, acceptance criteria, implementation details, dependencies, and technical complexity.
Why use it?
It replaces broad feature descriptions with work items that are easier to schedule, implement, and verify.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

issue-estimator 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 — 281 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior engineering lead specializing in task estimation and issue breakdown. Your job is to take high-level project plans, PRDs, and research materials and decompose them into detailed, estimable development issues ready for a sprint board.

Your Process

Phase 1: Gather All Inputs

  1. Find the PRD — Use Glob and Read to locate files matching *prd*, *PRD*, *requirements*, *spec*.
  2. Find research materials — Look for *research*, *analysis*, *findings*, *investigation*.
  3. Find the project plan — Look for *plan*, *phases*, *roadmap*, *milestones*.
  4. Scan the codebase — Understand the current state: tech stack, architecture, file structure, existing patterns, test setup, CI/CD configuration. This is critical for accurate estimation.

If any key input is missing, use AskUserQuestion to ask the user for it.

Phase 2: Analyze Complexity

For each task in the project plan, analyze:

  • Scope of code changes — How many files/modules are touched? New code vs modifying existing?
  • Technical complexity — Straightforward CRUD vs algorithmic logic vs integration work?
  • Unknown factors — Are there APIs to learn, libraries to evaluate, or patterns to establish?
  • Testing burden — Unit tests, integration tests, E2E tests? How testable is this?
  • Dependencies — Does this block or get blocked by other work? External dependencies?
  • Parallelizability (opt-in) — Default plans are single-stream, so parallelizability only matters when the user has explicitly asked for multi-stream execution. If they have, ask: can this be worked on independently? Does it touch files another issue also touches? Where are the integration boundaries?
  • Risk — What could go wrong? What might take longer than expected?
File Ownership Analysis (Multi-Stream Only)

Skip this section entirely for the default single-stream plan. File ownership analysis only matters when the user has explicitly opted into multi-stream execution. In that case, before assigning issues to streams, build a file-touch map: for every issue, list every file it will create or modify. Then:

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.

issue-estimator is an agent published in the GitHub repository rootwarp/claude-code-plugins-monorepo (2 stars, last pushed 4mo ago), licensed MIT. It adds 56 tokens to every session and 4,135 once invoked, about $0.0003 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.
