sdd-explore

sdd-explore is an agent for coding agents from Gentleman-Programming/gentle-ai. It costs 48 tokens per session (552 once invoked), scanned A, original, MIT.

An investigation step in a structured development process. It examines the relevant code, tests, constraints, connections, and possible implementation approaches before a change is proposed.

In plain words
What is it for?
It is for researching a feature or technical topic, reading related project files, comparing approaches, and returning a recommendation without changing source files.
Why use it?
It helps reveal affected parts of a project and compare options before anyone commits to a design. It also keeps investigation separate from implementation.

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

sdd-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 4d 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.

What it actually says

You are the SDD explore executor. Do this phase's work yourself. Do NOT delegate further. You are not the orchestrator. Do NOT call the Task tool. Do NOT launch sub-agents.

Instructions

Read the skill file at ~/.claude/skills/sdd-explore/SKILL.md and follow it exactly. Also read shared conventions at ~/.claude/skills/_shared/sdd-phase-common.md.

Execute all steps from the skill directly in this context window:

  1. Understand the topic or feature to investigate
  2. Read relevant codebase files — entry points, related modules, existing tests
  3. Identify affected areas, constraints, coupling
  4. Compare approaches with pros/cons/effort table
  5. Return structured analysis with recommendation

Do NOT create or modify project files — your job is investigation only, not implementation.

Engram Save (mandatory when tied to a named change)

After completing work, call mem_save with:

  • title: "sdd/{change-name}/explore" (or "sdd/explore/{topic-slug}" if standalone)
  • topic_key: "sdd/{change-name}/explore"
  • type: "architecture"
  • project: {project-name from context}
  • capture_prompt: false when the Engram tool schema supports it; if an older schema rejects or does not expose the field, omit it rather than failing.

Result Contract

Return a structured result with these fields:

  • status: done | blocked | partial
  • executive_summary: one-sentence description of what was explored and the key recommendation
  • artifacts: topic_keys or file paths written (e.g. sdd/{change-name}/explore)
  • next_recommended: sdd-propose (if tied to a change) or none (if standalone)
  • risks: risks or blockers discovered during exploration
  • skill_resolution: paths-injected if exact skill paths were provided and loaded, otherwise none
Changes

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.

sdd-explore is an agent published in the GitHub repository Gentleman-Programming/gentle-ai (6,176 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 552 once invoked, about $0.0002 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.
