explore

explore is a skill for Claude Code, Codex from SienkLogic/plan-build-run. It costs 18 tokens per session (4,392 once invoked), scanned A, original, MIT.

A conversation tool for exploring an idea and deciding whether it should become a task, requirement, project phase, decision, or nothing yet.

In plain words
What is it for?
Use it to think through approaches, discuss possible requirements, research questions, and where the results should be recorded.
Why use it?
It helps turn unclear ideas into a useful direction without forcing premature requirements or implementation plans.

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

explore 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 today.

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

STOP — DO NOT READ THIS FILE. You are already reading it. This prompt was injected into your context by Claude Code's plugin system. Using the Read tool on this SKILL.md file wastes ~7,600 tokens. Begin executing Step 1 immediately.

Step 0 — Immediate Output

Before ANY tool calls, display this banner:

╔══════════════════════════════════════════════════════════════╗
║  PLAN-BUILD-RUN ► EXPLORING                                  ║
╚══════════════════════════════════════════════════════════════╝

Then proceed to Step 1.

/pbr:explore — Idea Exploration

You are running the explore skill. Your job is to help the user think through ideas that might become a todo, requirement, phase, decision, or nothing yet. This is Socratic conversation, not requirements gathering. No phase number is needed.

This skill runs inline (no Task delegation), with optional Task() spawns for context loading, upfront research, and mid-conversation research.

CRITICAL: Agent type rule — When spawning ANY research or analysis Task(), ALWAYS use subagent_type: "pbr:researcher". NEVER use general-purpose, Explore, or other non-PBR agent types. The PreToolUse hook will block non-PBR agents.

Context Budget

Reference: skills/shared/context-budget.md for the universal orchestrator rules. Reference: skills/shared/agent-type-resolution.md for agent type fallback when spawning Task() subagents.

Additionally for this skill:

  • Minimize file reads — this is a thinking skill, not a code analysis skill
  • Delegate deep research to a researcher subagent if investigation exceeds the read threshold:
    • At context_window_tokens < 500000 (200k model): delegate after 3-4 file reads
    • At context_window_tokens >= 500000 (1M model): delegate after 12 file reads Check context_window_tokens in .planning/config.json to determine which limit applies.

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.
