auto-propose-backlog-specs

auto-propose-backlog-specs is a skill for Claude Code from fjpulidop/specrails-core. It costs 30 tokens per session (2,780 once invoked), scanned A, original, MIT.

A product-discovery skill that examines a code project and proposes feature ideas. It records those ideas as GitHub Issues under the `product-driven-backlog` label.

In plain words
What is it for?
Use it to review the project by area, generate two to four feature ideas per area, and inspect the resulting backlog with `/specrails:get-backlog-specs`.
Why use it?
It helps turn an understanding of the existing product into a visible list of possible improvements without changing application code.

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

auto-propose-backlog-specs scanned grade A 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Analyze the project from a product perspective to generate new feature ideas. Syncs results to GitHub Issues labeled product-driven-backlog. Use /specrails:get-backlog-specs to view current ideas.

Input: $ARGUMENTS (optional: comma-separated areas to focus on. If empty, analyze all areas.)

IMPORTANT: This command only creates GitHub Issues. You may read files and search code to understand current capabilities, but you must NEVER write application code.


Areas

Read .specrails/config.yaml or CLAUDE.md to identify project areas/modules. If not defined, use high-level categories inferred from the codebase structure (e.g., Frontend, Backend, API, Data, Infrastructure, Developer Experience).


Execution

Launch a single explorer subagent (subagent_type: Explore, run_in_background: true) for product discovery.

The Explore agent receives this prompt:

You are a product strategist analyzing the this project (read name from CLAUDE.md, package.json, or directory name) to generate new feature ideas using the Value Proposition Canvas framework.

Your goal: For each area, propose 2-4 new features that would significantly improve the user experience. Every feature MUST be evaluated against the project's personas.

Areas to analyze: {all areas or filtered by user input}

Step 0: Read Personas

Before anything else, read all persona files: Read all persona files from .specrails/personas/*.md and .claude/agents/personas/*.md. For each persona, extract their Jobs, Pains, and Gains from the Value Proposition Canvas section.

These contain full Value Proposition Canvas profiles (jobs, pains, gains).

Research steps

  1. Understand current capabilities — Read codebase structure
  2. Check existing backlog — Avoid duplicating existing issues
  3. Think through each persona's day — For each area:
    • What does each persona need here?
    • What would a competitive tool offer?
    • What data is available but not surfaced?
  4. For each idea, produce a VPC evaluation:
    • Feature name (short, descriptive)
    • User story ("As a [user type], I want to [action] so that [benefit]")
    • Feature description (2-3 sentences)
    • VPC Fit per persona: Jobs, Pains relieved, Gains created, Score (0-5)
    • Total Persona Score: sum of all persona scores / max possible
    • Effort (High/Medium/Low)
    • Inspiration (competitor or product pattern)
    • Prerequisites
    • Area

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.
