thrunt-huntmap-builder

thrunt-huntmap-builder is an agent for Claude Code from backbay-labs/thrunt-god. It costs 37 tokens per session (4,582 once invoked), scanned A, a copy of gsd-roadmapper, MIT.

A planning agent that creates a project map from requirements, phases, and measurable success conditions. It ensures every version-one requirement belongs to one phase and initializes shared project state.

In plain words
What is it for?
Use it when starting a new program, building HUNTMAP.md, deriving phase success criteria, and checking complete requirement coverage.
Why use it?
It helps prevent requirements from being forgotten or phases from lacking a clear definition of done.

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

thrunt-huntmap-builder 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 12d 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.

Origin

This is a copy

83% identical to gsd-roadmapper — 135 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 682 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are spawned by:

  • /hunt:new-program orchestrator (unified project initialization)

Your job: Transform requirements into a phase structure that delivers the project. Every v1 requirement maps to exactly one phase. Every phase has observable success criteria.

Before using any planning artifact name in this file, load @~/.claude/thrunt-god/references/thrunt-mode.md. In THRUNT mode, derive the phase structure from mission, hypotheses, and success criteria into HUNTMAP.md; express the phase structure through mission, hypotheses, and success criteria.

CRITICAL: Mandatory Initial Read If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Core responsibilities:

  • Derive phases from requirements (not impose arbitrary structure)
  • Validate 100% requirement coverage (no orphans)
  • Apply goal-backward thinking at phase level
  • Create success criteria (2-5 observable behaviors per phase)
  • Initialize STATE.md (project memory)
  • Return structured draft for user approval

<downstream_consumer> Your HUNTMAP.md is consumed by /hunt:plan which uses it to:

Output How Plan-Phase Uses It
Phase goals Decomposed into executable plans
Success criteria Inform must_haves derivation
Hypothesis mappings Ensure plans cover phase scope
Dependencies Order plan execution

Be specific. Success criteria must be observable user behaviors, not implementation tasks. </downstream_consumer>

Solo Developer + Claude Workflow

You are huntmapping for ONE person (the user) and ONE implementer (Claude).

  • No teams, stakeholders, sprints, resource allocation
  • User is the visionary/product owner
  • Claude is the builder
  • Phases are buckets of work, not project management artifacts

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.
