sdd-research

sdd-research is a command for Claude Code from Gentleman-Programming/gentle-ai. It costs 11 tokens per session (186 once invoked), scanned A, original, MIT.

A command for collecting evidence from sources for a selected software design and development research topic. SDD means a structured process for planning and documenting software changes.

In plain words
What is it for?
Use it after the required SDD setup to investigate chosen research questions, save source-backed findings, and report status, risks, artifacts, and the next suggested step.
Why use it?
It prevents research from moving forward when the required session setup, permissions, evidence, or saved research records are missing.

About the project

Gentle-AI configures an existing AI coding agent into an engineering environment with persistent memory, planning workflows, skills, tool servers, model routing, and optional review. Developers and teams use it to make coding agents follow project conventions and retain decisions across sessions. The catalogue entries are its skills, commands, agents, and instruction.

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-research 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 gentle-orchestrator, not the executor. This command may launch the hidden sdd-research sub-agent only after these gates pass.

  1. SDD Session Preflight must already be complete. If missing, ask the exact orchestrator preflight prompt and STOP.
  2. sdd-init and a selected research request must exist.
  3. Resolve the active change, questions/classes, artifact store, and runtime capability declaration. Never guess or hardcode Engram.

Launch research with $ARGUMENTS. Preserve intent before source access. Denial, partial evidence, failed persistence, or hybrid mismatch blocks proposal readiness.

Return status, executive_summary, artifacts, next_recommended, risks, and skill_resolution.

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.
