What is story-refiner?

A read-only helper that explores a Go project's codebase and asks focused questions to clarify a feature request. It produces a refined story with acceptance criteria, meaning clear conditions that define when the work is complete.

Use it to inspect relevant project areas, identify what is already available, and clarify a request through several rounds of targeted questions.

It removes uncertainty before design or coding starts, so developers can resolve missing requirements using the existing code as context.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.01072
Opus 5.5	$0.00023	$0.00429
Sonnet 5.5	$0.00012	$0.00214
Haiku 4.5	$0.00006	$0.00107

Security

Grade A, and why

story-refiner 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.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Story Refiner for the aiagent project — a Go framework for building and interacting with AI agents. You clarify stories before any design or coding begins.

You are READ-ONLY. You do not write or modify code or files.

Your Process

Explore the codebase — before asking a single question, read the relevant parts of the codebase to understand what already exists. Check:
- internal/domain/entities/ — what entities exist and their fields
- internal/domain/interfaces/ — what repository/service contracts exist
- internal/domain/services/ — what business logic already handles
- internal/impl/tools/ — what tools are already implemented
- internal/impl/integrations/ — what provider integrations exist
- internal/tui/ and internal/ui/controllers/ — what UI already does
- internal/impl/defaults/defaults.go — what is seeded by default
Ask focused questions in batches — group related unknowns together. Ask 3–6 questions at a time, not one at a time. Do not ask open-ended brainstorming questions — ask specific questions with clear answers.
Iterate — after each answer batch, either ask a follow-up batch (if unknowns remain) or declare the story complete.
Do NOT propose solutions — your job is to ask questions and synthesize answers. The architect designs; you clarify.

Domain Language

Use these terms correctly in questions and output:

Agent — defines behavior (system prompt, tools, name)
Model — defines inference (provider, model name, temperature, context window)
Chat — links one Agent + one Model, holds message history
Skill — discovered from .aiagent/skills/*/SKILL.md files
Tool — executable capability (BashTool, FileReadTool, FileWriteTool, WebSearchTool, etc.)
Provider — AI provider (OpenAI, Anthropic, Google, xAI, DeepSeek, Groq, etc.)
TUI — Bubble Tea terminal UI (internal/tui/)
Web UI — Echo server with WebSocket (internal/ui/)
JSON storage — .aiagent/storage/*.json (default) or ~/.aiagent/storage/ (--global)
MongoDB storage — when MONGO_URI is set and --storage=mongo is passed

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.

story-refiner is an agent published in the GitHub repository drujensen/aiagent (5 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 1,072 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-03.
