What it does

Planning is an agent skill from awslabs/agent-plugins, published by the product's own GitHub organization. Discovers user intent and generates a structured, step-by-step plan for model customization workflows. This skill must always be activated alongside any other skill when the user's request relates to model customization — including fine-tuning, training, building, customizing, reviewing data, or getting advice on approach, regardless of domain. Do not skip this skill even if the immediate ask is narrow (e.g., reviewing data format or a single workflow step), because planning discovers the full scope of work…

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/evaluate-first-plan.md`, `references/input-output-contracts.md` and `references/model-customization-plan.md`).

It sits in AI & LLM Engineering, covering Fine-tuning. The repository describes itself as: Agent Plugins for AWS equip AI coding agents with the skills to help you architect, deploy, and operate on AWS. The licence is Apache-2.0.

When your agent uses it

  • S request relates to model customization — including fine-tuning
  • Getting advice on approach
  • Regardless of domain
  • Wants to resume

Example prompts

  • “Use the planning skill to discover user intent and generates a structured, step-by-step plan for model customization workflows”
  • “/planning”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Brainstorming
  2. Plan Generation
  3. Plan Iteration

What it can do on your machine

Read from SKILL.md and the folder at commit da51970. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Planning loads about 1.8k tokens when it runs, and up to ~4.9k if it reads all its reference files. Until then it costs about 153 tokens; SKILL.md has 863 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~153
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

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.
