exploration

A two-mode exploration guide: one mode turns rough ideas into agreed designs through discussion, and the other builds throwaway code to answer one design question.

In plain words
What is it for?
Use it to clarify requirements, test an uncertain technical approach with a short-lived prototype, or break a large request into smaller projects.
Why use it?
It separates deciding what to build from deciding how to build it, while keeping experiments from being mistaken for production code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

exploration 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Exploration (Design + Spike)

Two modes, selected by router dispatch context: design (brainstorm a design) or spike (throwaway prototype). DESIGN includes an optional inline sub-procedure, the Doubt Pass, for high-stakes decisions — it is not a third mode.

Mode: DESIGN

Turn rough ideas into validated designs through collaborative dialogue. Understand what to build BEFORE designing how to build it. Use the user's domain language — don't invent new terminology when the repo or prompt already has a stable name.

Scope Triage (Front of Flow)

Before opening the interview, decide whether this is ONE design or MANY. A request spanning multiple independent subsystems produces a sprawling, unfocused design.

Multi-subsystem trigger: 2+ pieces that could be built, tested, and shipped independently — different surfaces, data stores, deploy targets, or pieces joined only by "and."

If multi-subsystem: emit a decomposition recommendation (independent pieces, relationships, build order), then brainstorm ONLY the first sub-project. The router carries the rest forward.

Synthesize-Now Fast Path

If goal + constraints + acceptance are ALL already evident from the prompt or context: skip the interview, draft the design directly, present for confirmation in ONE pass. Still record rejected alternatives (ADR notes). On correction, fix the named gap — don't restart the full interview.

Gate: take the fast path ONLY when all three are stated, not inferred. When in doubt, interview.

Interview (when fast path gate fails)

Cover these 5 dimensions, but only ask about dimensions that are still unresolved. Skip a question when the answer is already explicit — write the inferred answer, mention the assumption, continue.

  1. Purpose — what problem does this solve?
  2. Users — who will use this?
  3. Success — how will we know it works?
  4. Constraints — limitations, requirements, out-of-scope
  5. Scope — single module, single file, full feature, cross-cutting

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.

exploration is a skill published in the GitHub repository romiluz13/cc10x (164 stars, last pushed 29d ago), licensed MIT. It adds 56 tokens to every session and 2,500 once invoked, about $0.0003 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.
