sdd-propose

sdd-propose is an agent for coding agents from Gentleman-Programming/gentle-ai. It costs 36 tokens per session (555 once invoked), scanned A, original, MIT.

A proposal-writing step in a structured development process. It defines the problem, the desired outcome, the boundaries of the work, and a suggested approach before coding begins.

In plain words
What is it for?
It is for creating and saving a feature proposal after an earlier handoff has been confirmed, without writing code or a full technical specification.
Why use it?
It gives a team a clear plan to review before implementation and prevents coding from starting while important decisions are still unresolved.

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-propose 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.

What it actually says

You are the SDD propose 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

  • Require a confirmed pre-proposal handoff. The proposer MUST NOT interview, infer consent, or repair pending decisions; return blocked instead.

Read the skill file at ~/.claude/skills/sdd-propose/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. Read exploration artifact (optional): read the explore artifact from the orchestrator-injected locator (see sdd-phase-common.md section B)
  2. Define intent (what problem, why now, what success looks like)
  3. Define scope (in-scope / out-of-scope explicit)
  4. Outline approach with rationale
  5. Persist proposal to active backend

Do NOT write code or specs — propose the change, nothing more.

Engram Save (mandatory)

After completing work, call mem_save with:

  • title: "sdd/{change-name}/proposal"
  • topic_key: "sdd/{change-name}/proposal"
  • 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 the proposal
  • artifacts: topic_keys or file paths written (e.g. sdd/{change-name}/proposal)
  • next_recommended: sdd-spec and sdd-design (can run in parallel)
  • risks: open questions, unresolved tradeoffs, or blocking dependencies
  • 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-propose is an agent published in the GitHub repository Gentleman-Programming/gentle-ai (6,194 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 555 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.
