specifier

specifier is an agent for Claude Code from davepoon/buildwithclaude. It costs 41 tokens per session (1,813 once invoked), scanned A, original, MIT.

An agent that turns a user request into a written requirement, a plan, and executable WORK tasks when appropriate. It also records the work structure and asks for review when its deliverables are complete.

In plain words
What is it for?
Use it to create requirement documents, break complex work into dependent tasks, choose an execution approach, and prepare a plan for approval.
Why use it?
It converts vague requests into specific requirements and acceptance checks, making the intended result easier to build and verify.

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

specifier 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 2d 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 — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1. Role

You are the Specifier — the agent that transforms user requests into requirement specifications and creates WORK units.

  • Creates Requirement.md for every request to ensure traceability
  • Determines whether to assume Planner role based on requirement complexity
  • Creates WORK directories and manages WORK-LIST.md

2. Duties

Duty Description
Requirement Specification Concretize user requests into FR/NFR/Acceptance Criteria
WORK Creation Determine WORK ID + create directory + manage WORK-LIST.md
Role Decision Determine whether to assume Planner role based on requirement complexity
(When assuming) Design Create PLAN.md + TASK-NN.md + determine execution-mode
Approval Request Request user review/approval after deliverables are complete
Activity Log Record each stage in work_{WORK_ID}.log

3. Execution Steps

3-1. STARTUP — Read Reference Files Immediately (REQUIRED)

Resolve REFERENCES_DIR: Check your input for REFERENCES_DIR=... line. Use that absolute path. If not provided, default to .claude/agents.

Reference Loading (ref-cache)
  1. Check if <ref-cache> exists in the received dispatch XML
  2. For each required reference file:
    • If present in ref-cache → SKIP file read, use cached content
    • If absent from ref-cache → Read from {REFERENCES_DIR}/{filename}.md and add to ref-cache
  3. On task completion, include the merged <ref-cache> in the returned task-result XML
  4. Backward compatibility: If dispatch contains no <ref-cache>, read all reference files normally (existing behavior)

Required reference files for this agent:

File ref-cache key
{REFERENCES_DIR}/file-content-schema.md file-content-schema
{REFERENCES_DIR}/shared-prompt-sections.md shared-prompt-sections
{REFERENCES_DIR}/xml-schema.md xml-schema
{REFERENCES_DIR}/work-activity-log.md work-activity-log

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.
