What it does

Tool Foundation Sprint Basics is an agent skill from product-on-purpose/pm-skills. Day 1 morning move of a Foundation Sprint. Forces explicit team choices on target customer, important problem, team advantage, and competitors and alternatives. Produces a single coherent strategic frame that becomes the input to Day 1 afternoon Differentiation. Use after the sprint brief is signed and Day 1 morning is scheduled. Bundled artifact, not four separate decisions.

Its SKILL.md is about 2.3k 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

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

  1. Target customer (25-35 minutes)
  2. Important problem (20-30 minutes)
  3. Team advantage inventory (20-30 minutes)
  4. Competitor and alternative map (20-30 minutes)

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 Basics loads about 2.3k tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 102 tokens; SKILL.md has 1,101 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.4k

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 Basics

Day 1 morning of a Foundation Sprint. The team makes four foundational choices explicit: who the product is for, what important problem it solves, why this team has a right to win, and what customers do today instead. The output is one coherent strategic frame, not four separable decisions.

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

When to Use

  • Day 1 morning of a Foundation Sprint, after the brief is signed.
  • The team has sufficient customer and market knowledge (per readiness verdict) to make informed choices.
  • Each of the four sub-decisions is open or contested; the team has not pre-aligned on any of them.
  • The Decider is in the room and ready to sign off on the bundled output before lunch.

When NOT to Use

  • The team lacks enough customer knowledge to choose a target customer or name an important problem. Run customer research or problem framing first; revisit when readiness criterion 3 passes.
  • The team has already committed to a specific customer-problem pair and just wants to validate it. Use a lighter validation tool; Basics is for genuine decision-making, not ratification theater.
  • Day 1 morning has slipped into afternoon. Differentiation depends on Basics being complete; if Basics did not produce a coherent frame by lunch, do not start Differentiation. Reframe or postpone.

What This Skill Produces

A single bundled artifact with five sections:

  1. Target customer statement: a specific, named customer with markers (demographic, behavioral, contextual).
  2. Important problem statement: a customer-perceived pain strong enough to drive switching from alternatives.
  3. Team advantage inventory: the capabilities, insights, relationships, data, and timing edges that make this team credible against the problem.
  4. Competitor and alternative map: direct competitors, substitute workflows, manual workarounds, internal tools, and the strongest baseline of all: doing nothing.
  5. Note-and-Vote trace: a record of how each sub-decision was made, including alternatives considered and Decider rationale.

The artifact is treated as one coherent output, not four separate ones. The team signs off on the bundled frame, not on the components in isolation. See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for the Brainshelf example.

The Four Sub-Decisions

Each sub-decision uses tool-note-and-vote (the silent ideation + voting + Decider supervote protocol). The skill structures the sequence but the decision protocol is the standalone note-and-vote tool.

1. Target customer (25-35 minutes)

The team produces 3-7 candidate customer descriptions through silent ideation, then votes, then the Decider supervotes one. The chosen customer MUST be specific (not "SaaS PMs" but "PMs at Series-B SaaS companies between 20 and 100 engineers"). The skill rejects vague segments and prompts the team to add markers until the description names someone the team can recognize.

2. Important problem (20-30 minutes)

The team names 3-7 candidate pains the chosen customer experiences. Vote, then Decider supervote. The chosen problem MUST be painful enough to drive switching from current behavior (including doing nothing). Mild annoyances are not Important Problems; the skill enforces this by asking explicitly: "What does the customer currently do, and why would they leave it for our solution?"

3. Team advantage inventory (20-30 minutes)

The team enumerates its specific edges: capabilities, insights, relationships, data, technology, distribution, timing. Vote to surface the top 2-3 (multi-vote), Decider confirms. The skill rejects generic advantages ("great team," "passionate") and prompts for specific evidence ("Sam previously built X at Y company"; "Riley has a 12k-member network in our target segment").

4. Competitor and alternative map (20-30 minutes)

The team maps the full alternative space: direct competitors, substitute workflows, manual workarounds, internal tools, and "do nothing." For each, the team notes what customers use it for and why people leave (or stay). The skill enforces inclusion of "do nothing" as a competitor; many teams forget that inertia is often the strongest alternative.

Inference Inputs

InputWhat the skill does with it
Sprint briefReads the Decision Target to scope which customers and problems are in-scope; out-of-scope candidates are flagged before voting
Customer/market context packetPre-populates the silent ideation board with previously-surfaced candidates so the team doesn't reinvent them
Competitor knowledgePre-populates the alternative map with already-known competitors; the team adds and discusses rather than starts cold
Team advantage notesSurfaces the team's existing self-assessment; voting refines and prioritizes

Common Pitfalls

  • Vague customer. "SaaS PMs" or "readers" is not a target customer. The skill prompts for markers until the team can name a specific person archetype.
  • Mild-annoyance problems mistaken for painful ones. If the customer would not switch from doing nothing or from a paid alternative, the problem is not painful enough. The skill tests this explicitly.
  • Generic team advantages. "Great engineers" is not an advantage; "Sam built the original Pocket sync engine and knows offline-first patterns" is. The skill rejects unspecific advantages and prompts for evidence.
  • Ignoring "do nothing" as a competitor. The most common oversight. Many teams skip it because they think of competitors as named products; the skill forces inclusion.
  • Treating the four sub-decisions as separable. A target customer whose important problem is not solvable by the team's advantage cannot win. The skill ratifies the BUNDLED artifact, not the components; if the components don't cohere, the team revisits.
  • Skipping note-and-vote trace. The decision moments are load-bearing. Without the trace, Day 1 PM Differentiation begins on a fragile foundation and may end up re-litigating Basics under a different name.

Decider Role

The Decider's job during Basics is to:

  1. Frame each of the four sub-decisions (or approve the facilitator's framing).
  2. Listen during silent ideation and vote discussion without dominating.
  3. Supervote each sub-decision with explicit rationale when the supervote diverges from the team's top choice.
  4. Sign off on the bundled artifact as a coherent strategic frame before Differentiation begins.

A Decider who blesses everything without challenge is not adding value; a Decider who overrides without rationale is not building trust.

Cross-Skill Usage

Prerequisites: tool-foundation-sprint-brief. The Brief's Decision Target tells the skill which customer-problem space is in-scope.

The skill invokes tool-note-and-vote four times (once per sub-decision). Each invocation produces its own decision record; the four traces are aggregated into the bundled artifact.

Next invocation in the sprint: tool-foundation-sprint-differentiation on Day 1 afternoon, immediately after lunch.

Decider Checkpoint

This skill ends with a Decider Checkpoint in references/TEMPLATE.md. The Decider signs off on the bundled artifact as a coherent strategic frame, not on the components individually. Without sign-off, Differentiation cannot start cleanly because the inputs are still under negotiation.
