What it does

Tool Foundation Sprint Approach Options is an agent skill from product-on-purpose/pm-skills. Day 2 morning move of a Foundation Sprint. Forces generation of 3 to 7 candidate approaches as one-page summaries before the team converges on a top bet. Use after Day 1 is signed and before Magic Lenses on Day 2 afternoon. Enforces a minimum of 3 approaches to prevent first-idea anchoring. Each approach summary names what it is, why it serves the differentiators, and includes a simple visual.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `HISTORY.md`, `references/EXAMPLE.md` and `references/TEMPLATE.md`).

The repository describes itself as: 68 plug-and-play, best-practice product management skills for AI agents: 30 Triple Diamond phase + 11 foundation + 12 utility + 15 tool (Foundation Sprint + Design Sprint). Plus… The licence is Apache-2.0.

Workflow steps

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

  1. Frame the approach space (5 min)
  2. Silent ideation (15-20 min)
  3. Cluster and select 3-7 (15-25 min via Decider call)
  4. One-page summarize each approach (25-40 min)
  5. Cross-summary review (5-10 min)

What it can do on your machine

Read from SKILL.md and the folder at commit 1cef1a9. 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.

    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

Tool Foundation Sprint Approach Options loads about 2k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 109 tokens; SKILL.md has 976 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~109
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4k

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.

Foundation Sprint Approach Options

Day 2 morning of a Foundation Sprint. The team forces itself to generate multiple plausible approaches before committing to one. The skill enforces a minimum of 3 approaches; anchoring on a single approach is the most common Day 2 failure mode.

Family contract: docs/reference/skill-families/foundation-sprint-skills-contract.md. This skill is a member of foundation-sprint-skills.

When to Use

  • Day 2 morning of a Foundation Sprint.
  • Day 1 is signed; the Mini Manifesto, decision principles, and differentiation chart are committed.
  • The team is ready to generate candidate approaches before evaluating them through Magic Lenses in the afternoon.

When NOT to Use

  • Day 1 is unresolved. Approach Options without differentiation context produces approaches that miss the strategic position.
  • The team has only one approach in mind and is unwilling to generate alternatives. The skill forces minimum 3; if the team refuses, the issue is sprint discipline, not tooling.
  • More than 7 approaches are emerging organically. The skill caps generation at 7; beyond that the team is generating features, not strategic approaches.

What This Skill Produces

A single bundled artifact containing:

  1. 3 to 7 one-page approach summaries, each with:
    • Name and label (color, letter, ID)
    • One-sentence "what it is"
    • "Why it's a good idea" rationale (1 short paragraph)
    • Simple doodle or textual visual description
    • How the approach serves the two chosen differentiators
  2. Approach set summary table comparing all approaches at a glance (label, name, capture mechanism, recall mechanism, primary trade-off).

See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for the Brainshelf example.

Sequence (75 minutes)

Step 1: Frame the approach space (5 min)

The facilitator restates the differentiation: "We are committing to [differentiator 1] and [differentiator 2]. Approaches that fail either of these are out of scope." This sets the boundary; the team generates inside it, not outside it.

Step 2: Silent ideation (15-20 min)

Each team member generates 2-4 candidate approaches silently. Cluster duplicates. Surface 8-12 candidates.

Step 3: Cluster and select 3-7 (15-25 min via Decider call)

The team clusters similar approaches and the Decider narrows to 3-7 candidates that will be one-page-summarized. The 3-minimum is enforced; if the team produces 2 candidates after clustering, push the team back to ideation to generate at least one more.

Step 4: One-page summarize each approach (25-40 min)

Each team member takes 1-2 approaches and writes the one-page summary. Each summary names:

  • Label: a color, letter, or short identifier (Yellow, Blue, Approach A, etc.)
  • What it is: one sentence the customer would understand
  • Why it's a good idea: short paragraph naming the customer value and the team's ability to deliver
  • Visual: a simple doodle or textual description of what the customer sees or does
  • How it serves the differentiators: one or two lines per chosen differentiator
Step 5: Cross-summary review (5-10 min)

The team reviews the full set, flagging summaries that don't fit the differentiators or that overlap so heavily with another approach that they're duplicates. The Decider approves the set advancing to Magic Lenses.

Approach Generation Discipline

The skill enforces five rules at decision-point:

  1. Minimum 3, maximum 7. Fewer than 3 means the team is anchored on one idea; more than 7 means the team is generating features.
  2. Each approach must be a strategic path, not a feature. "Add a settings screen" is a feature; "make capture the home screen" is a strategic path.
  3. Each approach must serve both chosen differentiators (not just one). An approach that wins on differentiator 1 but fails differentiator 2 should be either revised or dropped.
  4. Each approach must be visually describable. If the team can't draw it on a card, the approach is too abstract for the sprint.
  5. No first-idea bias. The first approach the team thought of should be included only if it survives the differentiation check; many teams find their initial idea is not the strongest after generating alternatives.

Inference Inputs

InputWhat the skill does with it
Basics bundled artifactReads target customer to ensure approaches are designed for them, not for an adjacent customer
Differentiation bundled artifactReads the 2 chosen differentiators and the 2x2 position; flags approaches that miss either differentiator
Approach candidates (optional)If pre-supplied, pre-populates the silent ideation board; team adds and refines rather than starting cold

Common Pitfalls

  • Generating features instead of approaches. "Add notifications" is not an approach; it's a feature. The skill enforces strategic-path framing.
  • Too few options. Stopping at 2 approaches because "those are obviously the choices" anchors the team. Force a third even if it's intentionally weaker; it surfaces the trade-offs.
  • Approaches that fail one differentiator. An approach that beats differentiator 1 but loses differentiator 2 has rejected the Day 1 strategic commitment. Either drop it or revise it.
  • Skipping the visual. "I can describe it in prose" defeats the purpose. The visual forces concreteness.
  • Overlap masquerading as distinct approaches. Two summaries that differ only in implementation detail are one approach. Cluster them.

Decider Role

The Decider's job during Approach Options:

  1. Restate the differentiation boundary at the start.
  2. Narrow the clustered candidates to 3-7 for one-page summary.
  3. Approve the final set advancing to Magic Lenses; reject summaries that drift from the differentiation.

The Decider does NOT pick a top approach in this skill. Magic Lenses produces the top bet; Approach Options produces the candidates Magic Lenses will evaluate.

Cross-Skill Usage

Prerequisites: tool-foundation-sprint-differentiation. The Day 1 strategic position is the load-bearing input.

Next invocation: tool-foundation-sprint-magic-lenses in the afternoon. The approach set produced here is the input to Magic Lenses scoring.

Decider Checkpoint

This skill ends with a Decider Checkpoint in references/TEMPLATE.md. The Decider signs off on the set of approaches advancing to Magic Lenses, confirming none are out-of-scope and none are duplicates. Without sign-off, Magic Lenses begins with an unstable candidate set.
