tool-foundation-sprint-differentiationDay 1 afternoon move of a Foundation Sprint. An agent skill from product-on-purpose/pm-skills.
Tool Foundation Sprint Differentiation is an agent skill from product-on-purpose/pm-skills. Day 1 afternoon move of a Foundation Sprint. Converts the morning's Basics frame into a defensible strategic position by scoring differentiator candidates against customer-perceived value, choosing two committed differentiators, plotting alternatives on a 2x2 chart, writing decision principles, and producing a one-page Mini Manifesto. Use after Basics is signed; before Approach Options the next morning.
Its SKILL.md is about 2.2k 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`).
It sits in Data & Analytics, covering Data visualization. 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.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 1cef1a9. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Tool Foundation Sprint Differentiation loads about 2.2k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 1,047 words of instructions outside code blocks.
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.
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.

Day 1 afternoon of a Foundation Sprint. The team converts the morning's Basics frame (customer, problem, advantage, competitors) into a defensible strategic position. The output is a one-page Mini Manifesto that the team and Decider sign as the Day 1 strategic summary.
Family contract: docs/reference/skill-families/foundation-sprint-skills-contract.md. This skill is a member of foundation-sprint-skills.
A single bundled artifact with five sections:
See references/TEMPLATE.md for the canonical structure and references/EXAMPLE.md for the Brainshelf example.
Each team member produces 3-5 candidate differentiators silently. Cluster duplicates, then surface the full set (8-15 candidates is typical). The candidates can be classic (speed, price, simplicity, breadth, depth, trust) or custom (specific to this product or market).
Score each candidate on three dimensions, 1-5 scale:
Sum the three for a rough score. Top 5-7 candidates advance.
The team narrows to two differentiators through tool-note-and-vote. The two MUST be observable to the customer (not internal-team values) and deliverable by the team (not aspirational). The Decider supervotes if scoring produces a tie or the team is split.
Place the two differentiators as the chart axes. Plot the competitor set from Basics (including "do nothing"). Position the product where it can occupy unoccupied space. If the unoccupied position is too far from where competitors cluster, the team may be drifting into a niche that customers don't recognize; if the position overlaps with a strong competitor, the differentiation is not strong enough.
Convert the two differentiators into 3-5 operational principles. Examples:
Principles are NOT marketing copy. They are decision-making rules for future product calls.
The Decider drafts a one-page Mini Manifesto in the team's voice. Tone is plain, declarative, and direct about what the product is NOT (this is the part teams skip and shouldn't).
| Input | What the skill does with it |
|---|---|
| Basics bundled artifact | Reads target customer (for "customer-perceived" check), problem (for "would this differentiator solve the problem"), advantages (for "can the team deliver"), and competitor map (for chart plotting) |
| Differentiation candidates | If pre-supplied, pre-populates the silent ideation board; otherwise the team generates them in Step 1 |
The Decider's responsibilities during Differentiation:
Prerequisites: tool-foundation-sprint-basics. The Basics bundled artifact is the load-bearing input.
The skill invokes tool-note-and-vote at least once (to choose the two differentiators). Additional note-and-vote invocations may happen for the principles list if the team is split.
Next invocation: tool-foundation-sprint-approach-options on Day 2 morning. The chosen differentiators and the decision principles constrain which approach options are in-scope.
This skill ends with a Decider Checkpoint in references/TEMPLATE.md. The Decider signs off on the two differentiators, the 2x2 position, the principles, and the Mini Manifesto as the Day 1 strategic summary. Without sign-off, Day 2 starts on an unstable strategic foundation.

Tool Foundation Sprint Differentiation fits situations like: tasks that involve Data visualization.
Run `npx skills add product-on-purpose/pm-skills --skill tool-foundation-sprint-differentiation -a claude-code`. Or copy the skill folder (skills/tool-foundation-sprint-differentiation in product-on-purpose/pm-skills) into .claude/skills/tool-foundation-sprint-differentiation in your project. Claude Code loads it when a task matches its description.
Run `npx skills add product-on-purpose/pm-skills --skill tool-foundation-sprint-differentiation -a codex`. Or copy the skill folder (skills/tool-foundation-sprint-differentiation in product-on-purpose/pm-skills) into .agents/skills/tool-foundation-sprint-differentiation in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add product-on-purpose/pm-skills --skill tool-foundation-sprint-differentiation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tool-foundation-sprint-differentiation, .gemini/skills/tool-foundation-sprint-differentiation, .github/skills/tool-foundation-sprint-differentiation and .opencode/skills/tool-foundation-sprint-differentiation in your project.
SKILL.md names no scripts, command-line tools or credentials: Tool Foundation Sprint Differentiation is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Tool Foundation Sprint Differentiation is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.4k tokens, read only when the agent opens those files.
