SkillAI & models

Planning gives your AI a structured way to handle model customization work. Once added, it figures out what you are trying to achieve and produces a clear step-by-step plan before any work begins. It is meant to be active alongside your other skills whenever a request involves customizing models.

Available today. Use it from your connected AI after setup.

After adding planning, keep it active whenever you ask your AI about model customization, such as fine-tuning or training a model. It will then pair with your other skills to lay out a plan for each request.

Then ask your AI: use the planning skill

What your AI can do with it

  • Work out what you actually want to accomplish before any work starts
  • Turn model customization requests into a clear step-by-step plan
  • Plan tasks like fine-tuning, training, building, and customizing models
  • Plan how to review your data as part of the workflow
  • Work together with your other model customization skills on every request

What this skill tells your AI

The instructions your AI receives, as published by awslabs/agent-plugins in plugins/sagemaker-ai/skills/planning/SKILL.md and read by ahel’s review.

Principles

  • One question at a time. Each question should resolve a branching decision in the plan. Avoid generic or out-of-domain questions.
  • Surface constraints early. If a user decision would constrain downstream options, flag it before the plan is finalized.
  • Keep plans short. Only include tasks that are necessary for the user's stated goal.
  • Don't ask what you already know. Check conversation history and project files before asking the user.

Phase 1: Brainstorming

Goal: Understand what the user wants to accomplish and identify which skills belong in the plan.

Read references/input-output-contracts.md, references/model-customization-plan.md, and references/evaluate-first-plan.md to:

  • Identify which skills could be relevant to the user's stated goal.
  • Check whether the user has the necessary input artifacts for each skill. If not, find the skills that generate those inputs and add them first.
  • Order skills to allow a smooth transition from one to the next and avoid dead ends.
  • Check if a recommended workflow matches the user's needs. If not, assess what modifications are needed and verify they are possible against the contracts table.
  • Decide which skills in a matching workflow can be skipped.
  • Surface limitations early — if a user decision (model choice, region, evaluation method) would constrain downstream options, mention it proactively, get user feedback, and adapt the plan accordingly.

During brainstorming:

  • Workflow choice gate: Before generating any plan, determine whether the user wants the evaluate-first workflow or the direct fine-tuning workflow. If the user has explicitly chosen (e.g., "evaluate first", "skip evaluation", "already evaluated the base model"), proceed with their choice. Otherwise, present both options with brief pros/cons and ask the user to choose. Saying "fine-tune" or naming a technique alone is NOT an explicit choice to skip evaluation — the user may not know evaluate-first is an option. Do NOT present a plan until the user has chosen a path. After they choose, read ONLY the corresponding reference plan.
  • Use the Restrictions column of the contracts table to flag constraints as soon as the relevant decision is made. Examples (non-comprehensive list, check contracts table for the full picture):
    • User picks a Nova model → alert that deployment regions are limited.
    • User picks a region → alert if it conflicts with model availability.
  • If a restriction applies, check whether it requires changes to other steps in the plan.
  • Do NOT ask the user about base model selection or preferences. Model selection is handled exclusively by the model-selection skill.
  • Move to Phase 2 as soon as you can determine which skills and tools the plan needs.

Phase 2: Plan Generation

Goal: Propose a structured plan for the user to review.

Generate a plan as a numbered list of tasks. Each task has:

  • A short name
  • A one-sentence description of what happens
  • Which skill handles it (if applicable)

Format:

Based on what you've described, here's what I propose:

1. ⬜ **[Task Name]** — [What happens]. *(Skill: [skill-name])*
2. ⬜ **[Task Name]** — [What happens]. *(Skill: [skill-name])*
3. ⬜ **[Task Name]** — [What happens]. *(Skill: [skill-name])*

Does this plan look right, or would you like to change anything?

Rules for plan generation:

  • Infer ordering from the Prerequisites column in the contracts table — a skill cannot appear before its prerequisites. If unsure, consult references/skill-routing-constraints.md.
  • Only offer capabilities covered by an available skill. If the user needs something no skill supports, say so.
  • Tailor the plan to the user's actual intent. Not every plan needs every skill.
  • If the user already has input artifacts (e.g., a trained model), skip the steps that produce them.

When the user approves the plan, write it to PLAN.md and save it under the project directory structure defined by the directory-management skill.

# Plan

1. ⬜ **[Task Name]** — [Description]. _(Skill: [skill-name])_
2. ⬜ **[Task Name]** — [Description]. _(Skill: [skill-name])_
3. ⬜ **[Task Name]** — [Description]. _(Skill: [skill-name])_

Status indicators:

  • ⬜ Not Started
  • 🔄 In Progress
  • ✅ Completed

Update PLAN.md whenever a task's status changes.


Phase 3: Plan Iteration

Goal: Refine the plan until the user approves it.

  • If the user suggests changes, regenerate the plan incorporating their feedback.
  • If the user approves, begin execution by handing off to the first task's skill.

Execution

Once the plan is approved:

  1. Before starting a task, update its status in PLAN.md to 🔄 (In Progress).
  2. If the task maps to a skill, load that skill's full SKILL.md before doing any work. Do not attempt the task from general knowledge — always defer to the skill's instructions.
  3. Execute the task by following the loaded skill's workflow.
  4. When the task completes:
    • Update its status in PLAN.md to ✅ (Completed). If the task generated output files (scripts, notebooks, manifests), record the file paths under the completed task:

      - [x] Fine-tune model
        - Output: `scripts/01_sft_finetuning.py`
        - Output: `manifests/sft-llama-20260515.json`
      
    • Briefly confirm completion and move to the next task.

  5. If the user interrupts with a new request mid-execution:
    • Completed tasks are immutable — do NOT modify them.
    • Regenerate the remaining tasks to incorporate the user's new input.
    • Present the updated remainder for approval before continuing.

Plan Completion

When all tasks in the plan are done: Present to the user:

"We've completed everything in the plan. What would you like to do next?"

This re-enters Phase 1 (Brainstorming) for a new goal. There is no terminal state — the conversation continues as long as the user wants.
