v0.13.0
What changed
The "10x" release: two new capabilities (a team skill and shared company memory), a smarter humanizer, and a round of content, tooling, and consistency upgrades across the bundle.
Added
teamskill. Convenes the co-founders in a single reply for cross-domain questions and big decisions: the most relevant co-founder leads, only the needed voices join, each is attributed by name, and every session ends in one clear recommendation. Portable, so it ships to Claude.ai, ChatGPT, and every other Agent Skills tool, bringing the multi-voice behavior that previously existed only in the Claude.ai project template to every platform. Added to the README skills list and install steps.- Shared company memory (Claude Code only). The four personas, both coaches, and the team skill now share one memory file,
./.cofounder-team/company.mdin the founder's project, holding the durable basics (stage, ICP, metrics, runway, burn, cap table, top goal). Skills read it at session start instead of re-asking, update it when facts change, and offer once to create it. Defined inshared/persona/company-memory.mdinside a{{FLAVOR:claude-code}}block; the portable build never sees it. Documented as cross-skill contract #4 inCLAUDE.md. - Humanizer: anti-fabrication rule. The workflow now forbids introducing facts, numbers, names, or citations not present in the source (placeholder or ask instead), and
references/patterns.mdopens with a note that the invented specifics in its "after" examples are illustrative, not licence to fabricate. - Humanizer: density judgment and newer tells. New "judge density, not presence" rule (count occurrences against length; one em dash is typography, three per paragraph is a tell), a warning that the voice examples are one voice, not the voice (so humanized pieces stop converging on the same casual-blogger sound), and extended watch lists: verb slop (leverage, unlock, streamline, robust, game-changer, holistic, supercharge, elevate, empower, seamless), "here's the thing", and perfectly parallel identical-opener bullet lists.
- Missing weak/strong examples in
startup-application-coach. The competitors, why-now, customer acquisition, and milestones questions inreferences/questions.mdnow each have a weak/strong pair (fictional companies, labelled as such).references/moats.mdgains a worked false-moat-to-honest-sequencing example plus two missing moat types: counter-positioning and regulatory/compliance position. - Missing slides in
pitch-deck-coach.references/slide-by-slide.mdgains a go-to-market slide section (one concrete channel, evidence it works, why it is hard to copy) and use-of-funds guidance on the ask slide (money-to-milestones lines, 18-to-24-month operating plan, and how to handle forms that demand 5-year projections). - Freshness discipline on program facts.
references/program-specific.mdopens with a standing rule (figures dated mid-2026; trust the program's live application over this file) and notes YC's four-batches-a-year cadence.references/video.mdhedges the verbatim YC instructions the same way and adds an explicit rule: real founders on camera, no AI avatars or synthetic voiceover, for both video types.
Changed
- Humanizer works on non-English drafts now, structurally. The old contract skipped the humanizer entirely for non-English copy. The new contract: lexical patterns (word lists, English idiom) remain English-only, but structural patterns (forced triplets, stacked hedges, signposting, label-colon-restatement lists, generic endings, chatbot leakage) apply in any language, so non-English drafts get a structural-only pass with a one-line note. Updated in the humanizer's scope section, the shared persona snippet, both coaches, the README, and
CLAUDE.mdcontract #3. - The build renders every
.mdfile, not justSKILL.md. Reference files now go through the same directive pipeline (includes, flavor blocks, variables), enabling shared snippets insidereferences/. Files without directives render byte-identical to a plain copy. Documented inCLAUDE.md. - Duplicated content moved to
shared/includes. The team-bio weak/strong example and the bottom-up TAM strong example (the two examples that had already drifted apart between files), both coaches' conversation-style and humanizer-language sections, and the personas' "no em dashes" / "default to brief" bullets now live in single shared snippets. The vision guidance intentionally stays two-level (summary in SKILL.md, detail invision.md) rather than deduplicated, since the two serve different loading stages. - The slop-check hook is quieter and sharper. It now scans only the text Claude just wrote (pre-existing text no longer re-triggers it on every edit), requires two kinds of tell (or a pile-up of AI words) before speaking, drops the lone en-dash and curly-apostrophe triggers, matches "let's dive" with either apostrophe, and syncs its word list with the humanizer's pattern catalog.
hooks/README.mdupdated to match. - Persona descriptions trimmed to what-and-when. The behavior summary sentence ("challenges weak assumptions... takes a clear position") is gone from all four personas' frontmatter descriptions; the domain keywords and triggers stay. The behavior itself is unchanged; it lives in each skill's "How you think" section, which the model now has no shortcut around.
- Bundle renamed to "The Co-Founder Team" in the README. Title and tagline now match the folder, skill names, and changelog. The GitHub repo URLs still point at
betahope/founding-teamuntil the repo itself is renamed (GitHub will redirect once it is). - Application coach: replaced the unexplained "$2.5M in revenue" acquisition target in
references/questions.mdwith stage-appropriate phrasing (first 100 users, first 20 paying customers, first $100K).
