discover

The discovery phase of a product-requirements workflow. It uses guided brainstorming to clarify what should be built before the work is planned.

In plain words
What is it for?
Use it to explore a feature idea, answer adaptive discovery questions, document assumptions, and prepare approved input for the next planning phase.
Why use it?
It helps uncover missing requirements and assumptions early, reducing the chance of planning or implementing the wrong thing.

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

discover 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 — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phase 1: Discover

Declarative phase skill. Invoked by the prd-taskmaster orchestrator when current_phase is DISCOVER. Never called directly by a user.

The one rule: invoke superpowers:brainstorming for discovery, intercept before it chains to writing-plans — we control the exit, not the brainstorm skill.

Entry gate

  1. Call mcp__plugin_prd_go__check_gate(phase="DISCOVER", evidence={}) for diagnostics.

    check_gate is an EXIT gate: it verifies the evidence to advance, not to enter. On first DISCOVER entry you have no evidence yet (the User Approval / Self-Approval Gate below produces user_approved=true OR auto_classification=CLEAR with assumptions_documented), so a gate_passed: false here is EXPECTED — the state machine's legal transitions already guarantee only legal entry.

    • First entry (no evidence yet): note the result and continue with the Procedure.
    • Re-entry: if the gate reports violations, report them and stop — it protects against re-running a completed phase or skipping ahead from SETUP.
  2. Detect execution context. If any of the following signals are present, switch to Autonomous Mode:

    • .claude/ralph-loop.local.md exists in the project root
    • An auto-enter / auto-approve daemon is running against this session
    • The skill was invoked with an explicit --autonomous flag
    • Parent orchestrator is a cron, /pentest-wtf, or /ralph-loop Otherwise proceed in Interactive Mode (default).

Discovery checklist

Copy into your response before running the procedure:

DISCOVERY CHECKLIST:
- [ ] Mode detected (Interactive vs Autonomous)
- [ ] Goal captured from skill args or soul purpose
- [ ] Adaptive questions completed (one at a time)
- [ ] Constraints extracted and listed
- [ ] Scale classified (Solo / Team / Enterprise)
- [ ] Discovery summary captured for GENERATE phase
- [ ] User approved (Interactive) or summary committed (Autonomous)

Interactive Mode (default — user present)

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.

discover is a skill published in the GitHub repository anombyte93/prd-taskmaster (593 stars, last pushed 18d ago), licensed MIT. It adds 92 tokens to every session and 2,237 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
