cs-onboardStructured C-suite onboarding via a founder interview that captures company context into a persistent file used by all advisory skills.
Cs Onboard is an agent skill from borghei/Claude-Skills. Structured C-suite onboarding via a founder interview that captures company context into a persistent file used by all advisory skills. Use when setting up advisory context, refreshing stale context, or onboarding a new executive.
Its SKILL.md is about 4.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4a698e8. 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 (its code samples are markdown).
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.
Cs Onboard loads about 4.8k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 2,112 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.

C-Suite Onboarding captures the company context that powers every C-level advisory skill. One structured conversation produces a persistent context file that transforms generic advice into specific, situationally-aware guidance. Without context, advisory skills give textbook answers. With context, they give your-company answers.
| Command | Duration | Purpose |
|---|---|---|
/cs:setup | 45 minutes | Full onboarding interview across 7 dimensions |
/cs:update | 15 minutes | Quarterly refresh -- what changed since last capture |
/cs:score | 5 minutes | Assess context completeness and freshness |
This is a conversation, not a form. Follow these rules:
Opening line:
"Tell me about the company in your own words -- what are you building and why does it matter?"
Then let the conversation flow naturally across the 7 dimensions.
What to capture: What they do, who it is for, the real founding "why," one-sentence pitch, non-negotiable values.
Key probes:
Red flags:
What to capture: Headcount (FT vs contractors), revenue range, runway, stage label, what broke in the last 90 days.
Key probes:
Stage Definitions:
| Stage | Signal | Typical Challenges |
|---|---|---|
| Pre-PMF | <$500K ARR, pivoting, searching | Finding the right customer/problem/solution fit |
| Early PMF | $500K-$2M ARR, repeatable sales | Hiring, process, not breaking what works |
| Scaling | $2M-$10M ARR, growth machine building | Middle management, culture preservation, unit economics |
| Optimizing | $10M+ ARR, efficiency focus | Innovation stagnation, org complexity, market defense |
What to capture: Self-identified superpower, acknowledged blind spots, archetype, what actually keeps them up at night.
Key probes:
Founder Archetypes:
| Archetype | Strength | Blind Spot | Advisory Focus |
|---|---|---|---|
| Product | Deep user empathy, product vision | Sales, go-to-market, delegation | Revenue strategy, hiring |
| Technical | Engineering excellence, technical moats | Business model, communication | GTM, storytelling, team |
| Sales | Revenue generation, relationships | Product depth, technical debt | Product strategy, engineering |
| Operator | Execution, processes, efficiency | Vision, innovation, risk-taking | Strategy, long-term planning |
Red flags:
What to capture: Team described in 3 words, last real conflict and how it was resolved, which values are real vs aspirational, strongest and weakest leader.
Key probes:
Red flags:
What to capture: Who is winning and why (honest version), real unfair advantage, the competitive move that could hurt them.
Key probes:
Red flags:
What to capture: Priority stack-rank across product/growth/people/money/operations, the decision they have been avoiding, the "one extra day" answer.
Key probes:
The "avoided decision" is often the most valuable insight. Common avoided decisions:
What to capture: 12-month target (specific and measurable), 36-month target (directional), exit vs build-forever orientation, personal success definition.
Key probes:
Red flags:

/cs:update)Trigger: Every 90 days or after a major event (fundraise, reorg, pivot, key hire/departure).
Opening: "It has been [X time] since we captured your company context. Let's do a quick refresh. What has changed?"
Walk each dimension with a single "what changed?" question:
| Dimension | Refresh Question |
|---|---|
| Identity | "Still the same mission, or has it shifted?" |
| Stage & Scale | "Team size, revenue, and runway now?" |
| Founder | "Has your role changed? What is stretching you?" |
| Team | "Any leadership changes? New key players?" |
| Market | "Any competitive surprises? Market shifts?" |
| Challenges | "What is the #1 problem now vs 90 days ago?" |
| Goals | "Still on track for the 12-month target?" |
After refresh:
Last updated timestampFreshDuring advisory conversations, new information surfaces. Capture it without disrupting flow.
Triggers for enrichment:
Protocol:
Never silently modify the context file. Always confirm before changes.
Handle gracefully -- never block the conversation.
| Missing | Approach |
|---|---|
| Stage | "Just to calibrate -- are you still finding PMF or scaling what works?" |
| Financials | Use stage + team size to infer. Note the inference. |
| Founder profile | Infer from conversation style. Mark as inferred. |
| Multiple founders | Context reflects interviewee. Note co-founder perspective may differ. |
| Recent context | "It's been a while since your last update. Should I assume things are roughly the same, or has something big changed?" |
The context file is loaded by every C-level advisory skill:
| Skill | Uses Context For |
|---|---|
| ceo-advisor | Strategic recommendations calibrated to stage and challenges |
| cfo-advisor | Financial guidance calibrated to runway and revenue |
| cto-advisor | Technical strategy calibrated to team and architecture |
| coo-advisor | Operations advice calibrated to scale and processes |
| cmo-advisor | Marketing strategy calibrated to stage and market position |
| internal-narrative | Narrative construction based on company truth |
| scenario-war-room | Risk variables calibrated to actual threats |
| Skill | Use When |
|---|---|
| ceo-advisor | Using context for strategic decisions |
| internal-narrative | Building narratives from the captured context |
| scenario-war-room | Modeling risks based on company context |
| context-engine | Technical implementation of context management for AI agents |
| Problem | Likely Cause | Resolution |
|---|---|---|
| Founder gives vague, marketing-speak answers | Interview not building trust; questions too formal | Reset with a personal question; follow a thread they care about; use reflection ("So what you're really saying is...") |
| Key dimensions left as "[not captured]" after interview | Founder avoided topic or interview ran out of time | Note which dimensions were skipped (avoidance signals importance); schedule targeted follow-up for missing areas |
| Context file feels generic, could apply to any company | Interviewer used the framework as a script, not a map | Re-interview with focus on specifics: names, numbers, stories; capture their actual words, not paraphrases |
| Advisory skills still giving textbook answers despite context | Context file too sparse or stale (>90 days) | Run /cs:score to assess completeness and freshness; schedule /cs:update if freshness is Stale or Expired |
| Quarterly refresh takes too long or feels redundant | Refresh covering all 7 dimensions instead of focusing on changes | Lead with "What changed?" per dimension; skip unchanged areas quickly; target 15 minutes total |
| Multiple founders give conflicting context | Different perspectives on stage, challenges, or priorities | Note the conflict explicitly in context file; mark which founder provided which data; flag for resolution |
| Context file modified without founder approval | AI agent or team member updated context silently | Enforce "never silently modify" rule; require explicit founder confirmation before any context update |
In scope: Structured founder interview across 7 dimensions (identity, stage, founder profile, team/culture, market/competition, challenges, goals), context file generation and maintenance, quarterly refresh protocol, context quality scoring (completeness and freshness), context enrichment during advisory sessions, privacy rules for external data handling, and missing context graceful handling.
Out of scope: Company financial modeling (use cfo-advisor), competitive intelligence gathering (use competitive-intel), team assessment or 360 reviews (use hr-operations/), product analytics (use cpo-advisor), and automated context capture from external data sources. This skill captures context through conversation, not data integration.
Limitations: Context quality depends entirely on founder candor; evasive or aspirational answers reduce advisory effectiveness. Single-founder interviews may miss co-founder perspectives. Context is a point-in-time snapshot; rapid company changes (pivot, reorg, fundraise) can make context stale before the 90-day refresh. Privacy rules prevent sharing specific context externally, which limits integration with external tools.
