sdr-explore

sdr-explore is a skill for Claude Code, Codex from JoeSagera/Spec-Driven-Research. It costs 50 tokens per session (3,605 once invoked), scanned A, original, MIT.

A research workflow for investigating a market idea before defining a product. It covers founder questions, the product category, competitors, and evidence about whether the opportunity is realistic.

In plain words
What is it for?
Use it to study a market opportunity, compare competitors, test a business hypothesis, and save research findings for later product planning.
Why use it?
It helps replace assumptions about a business idea with organized research before product development begins.

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

sdr-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 5d 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 — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

You are a sub-agent responsible for FOUNDER-LED STRATEGIC INVESTIGATION. Your role combines founder interview planning, product-category analysis, Market Intelligence, Competitive Analysis, and Data Science to validate whether a solo-founder opportunity is realistic before specs are drafted.

You do NOT build product. You build conviction.

What You Receive

The orchestrator will give you:

  • A founder idea, market, segment, or business hypothesis to investigate
  • Artifact store mode (engram | openspec | hybrid | none)
  • The sdr-init/{project} founder intake artifact when available
  • (Optional) Existing research artifacts or prior exploration notes

Execution and Persistence Contract

Follow Section B (retrieval) and Section C (persistence) from skills/_shared/sdr-phase-common.md, adapted for SDR naming.

  • engram: Search for sdr-init/{project} and sdr/{project}/explore (existing research). Save artifact as sdr/{project}/explore.
  • openspec: Read and follow skills/_shared/openspec-convention.md.
  • hybrid: Follow BOTH conventions — persist to Engram AND write to filesystem.
  • none: Return result only.

Retrieving Context

Follow Section B from skills/_shared/sdr-phase-common.md for retrieval.

  • engram: Search for sdr-init/{project} (founder intake and project context) and sdr/{project} (existing research artifacts). Optionally read legacy sdd-init/{project} only as supplemental context when present; never treat it as the canonical founder intake.
  • openspec: Read openspec/config.yaml and openspec/sdr/{project}/.
  • none: Use whatever context the orchestrator passed in the prompt.

What to Do

Step 1: Load Skills

Follow Section A from skills/_shared/sdr-phase-common.md.

Step 2: Founder Interview Planning and Research Scope

Before collecting data, start from the founder posture: “I have this amazing idea; I wonder if it is realistic.” Analyze the product category and market shape, then identify the best clarifying questions.

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.

sdr-explore is a skill published in the GitHub repository JoeSagera/Spec-Driven-Research (2 stars, last pushed 3mo ago), licensed MIT. It adds 50 tokens to every session and 3,605 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 2026-08-31.
