sdd-tasks

sdd-tasks is an agent for coding agents from Gentleman-Programming/gentle-ai. It costs 37 tokens per session (547 once invoked), scanned A, original, MIT.

A task-planning phase for specification-driven development, where a software design and its requirements are broken into an ordered implementation checklist. It identifies which tasks can be done in parallel.

In plain words
What is it for?
Use it to create an implementation plan from a specification and design, while leaving the actual coding to a later phase.
Why use it?
It turns a broad change into smaller, trackable pieces and shows how each piece satisfies a requirement.

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-tasks 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 tasks 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-tasks/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 spec artifact (required): read the spec artifact from the orchestrator-injected locator (see sdd-phase-common.md section B)
  2. Read design artifact (required): read the design artifact from the orchestrator-injected locator (see sdd-phase-common.md section B)
  3. Decompose work into ordered tasks (small enough to ship in isolation)
  4. Link each task to the spec requirement it satisfies
  5. Mark which tasks can run in parallel vs sequential
  6. Persist tasks to active backend

Do NOT implement — produce the checklist only.

Engram Save (mandatory)

After completing work, call mem_save with:

  • title: "sdd/{change-name}/tasks"
  • topic_key: "sdd/{change-name}/tasks"
  • 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 (total tasks, parallel vs sequential)
  • artifacts: topic_keys or file paths written (e.g. sdd/{change-name}/tasks)
  • next_recommended: sdd-apply
  • risks: task dependencies that introduce bottlenecks or unclear ownership
  • 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-tasks is an agent published in the GitHub repository Gentleman-Programming/gentle-ai (6,194 stars, last pushed today), licensed MIT. It adds 37 tokens to every session and 547 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.
