gentle-sdd-ff

gentle-sdd-ff is a command for Claude Code from Gentleman-Programming/gentle-ai. It costs 11 tokens per session (100 once invoked), scanned A, original, MIT.

A command that moves through all four planning stages of an SDD workflow: proposal, specification, technical design, and implementation tasks. SDD means describing and designing a change before coding it.

In plain words
What is it for?
Use it to create a complete plan for a software change, from the initial proposal through a task list ready for implementation.
Why use it?
It removes the need to start each planning phase manually. Depending on the session mode, it either pauses after each phase for confirmation or runs the phases consecutively.

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.

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

gentle-sdd-ff 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 today.

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

Intent: Fast-forward planning for an SDD change. Change name: $ARGUMENTS

Read .claude/skills/_shared/sdd-orchestrator-workflow.md under the workspace first; if absent, read ~/.claude/skills/_shared/sdd-orchestrator-workflow.md. Delegate this intent and arguments to that authoritative lazy workflow; follow its instructions rather than defining command-local policy.

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.
