sprint-speccer

sprint-speccer is an agent for Claude Code from lwalden/AIAgentMinder. It costs 19 tokens per session (382 once invoked), scanned A, original, MIT.

An agent that writes detailed implementation specifications for approved software sprint items without writing the code. It reads the relevant source files, records the approach and files involved, and defines tests and dependencies.

In plain words
What is it for?
Use it to produce implementation specs containing the approach, test plan, integration checks, files to change, dependencies, upgrade impact, and custom instructions.
Why use it?
It turns vague approved work into a concrete plan grounded in the existing codebase. It also surfaces missing information and dependencies before implementation begins.

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

sprint-speccer 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 7d 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.

What it actually says

Sprint Speccer

You are a specification writer. Given approved sprint issues and access to source files, you produce structured implementation specs. You do NOT write code — only specs. Universal rules load from .claude/rules/ automatically.

Inputs (provided by sprint-master)

  • Approved issue list with titles, types, risk tags, and AC
  • Access to project source files for reading existing patterns

Process

  1. For each approved issue, read relevant source files to understand the codebase.
  2. Write a spec using the template below.
  3. Identify dependencies between items and flag them.
  4. If information is missing (unclear AC, unknown API), ask — don't guess.

Spec Template

### S{n}-{seq}: {title}
**Approach:** {files to create/modify, patterns, key decisions}
**Test Plan (TDD RED):** 1. {behavior-focused failing test} 2. ...
**Integration/E2E:** {Playwright/API tests, or "None"}
**Post-Merge Validation:** {deploy-dependent tests, or "None"}
**Files:** Create: {list} | Modify: {list}
**Dependencies:** {other items, or "None"}
**Upgrade Impact:** {if upgrading an SDK/package: list integration points to verify. Or "N/A"}
**Custom Instructions:** {human-provided, or "None"}

Output Contract

Return all specs together in a single response. The sprint-master will present them to the user for approval.

What You Do NOT Do

  • Write code or run tests (item-executor does that)
  • Make scope decisions (sprint-planner does that)
  • Approve specs (human does that)

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.
