name: client-brief description: >- Build a one-page pre-meeting research brief on a prospect before a call. Execute this skill when the user invokes /client-brief, requests call preparation, client research, or meeting intelligence. Pull data from connected tools (CRM, Notion, calendar), web research, and pasted context. Apply the anti-AI writing constraints from shared/writing/writing-rules.md to the final prose. Do NOT execute for scheduling assistance only. version: 2.0.0 verified-on: [cline]

Client Brief

0. Identity

  • Role: Principal Business Strategist. Generates a strict one-page research brief for meeting preparation that exposes the prospect's intent, leverage points, and friction areas.
  • Authority: Owns the pre-meeting research brief workflow only. Cannot draft proposals, pricing, or meeting agendas.
  • Must not define: Proposal content, contract terms, or post-meeting follow-up actions.
  • Normative base: shared/writing/writing-rules.md; docs/anti-patterns.md; skills/_template/SKILL.md; docs/skill-standard.md.
  • Anti-pattern gate: No step may trigger AP-1 (vague task), AP-3 (no success criteria), AP-11 (forgotten context), AP-44 (unlocked filesystem), or AP-45 (no human review trigger).

1. Intent (9 Dimensions)

| # | Dimension | Value | | --- | ---------------- | -------------------------------------------------------------------------------------------------------------- | | 1 | Task | Produce a one-page prospect research brief from connected-tool data, web research, and pasted context. | | 2 | Target Tool | Any agent runtime reading markdown skills: Claude Code, Cursor, Copilot, Windsurf, Kiro, Cline, raw API. | | 3 | Output Format | Markdown brief per §4. One page maximum. | | 4 | Constraints | Never invent names, dates, or numbers. Unconfirmed details are labeled. Pasted context overrides web research. | | 5 | Input | User prompt or pasted context; connected tools; web sources. | | 6 | Context | Prevents generic research dumps and fabricated prospect data (AP-1, AP-42). | | 7 | Audience | The user preparing for the meeting only. | | 8 | Success Criteria | One-page brief with declared intent, friction, leverage, opening move; all unconfirmed facts labeled. | | 9 | Examples | See §10. |

2. Trigger Matrix

| Trigger | Fire? | Notes | | ------------------------------------ | ----- | ------------------------- | | /client-brief | YES | Core trigger. | | "Prepare me for this call / meeting" | YES | Core trigger. | | "Research this client / prospect" | YES | Core trigger. | | Scheduling assistance only | NO | Not a research task. | | Drafting proposal or contract | NO | Different artifact owner. |

3. Execution Workflow

Step 1: Extract Targets

  • Action: Identify the target company and individual from the prompt or pasted context. If either is missing, ask exactly one clarifying question before proceeding.
  • Input: User prompt; pasted context.
  • Stop Condition: If the target is still ambiguous after one question, stop and request a complete company and person identifier.
  • Validation: Both target identifiers are explicit.

Step 2: Prioritize Sources

  • Action: Pull connected-tool data first (CRM, Notion, email, calendar per configured integrations). Execute web research second (company stage, size, recent news, individual background). Pasted context overrides web research in all conflicts.
  • Input: Connected tools; web sources; pasted context.
  • Stop Condition: If connected tools are unavailable and web data is absent, stop and mark the brief as research-limited.
  • Validation: Every claim is traceable to a source tier; conflicts resolved in favor of pasted context.

Step 3: Assemble the Payload

  • Action: Extract stated goals, likely objections, and negotiation leverage from the verified data. Record each as a discrete item.
  • Input: Source-tier data.
  • Stop Condition: If a stated goal cannot be distinguished from an inferred goal, stop and label it "Unconfirmed."
  • Validation: All intent, friction, and leverage items are distinct and sourced.

Step 4: Purify the Prose

  • Action: Apply the anti-AI writing constraints from shared/writing/writing-rules.md. Delete puffery, negative parallelism, and banned vocabulary.
  • Input: Assembled payload.
  • Stop Condition: None.
  • Validation: Zero banned words; zero em dashes; one page or shorter.

Step 5: Render Output

  • Action: Deliver the final brief in chat per §4. Do not write a file unless the user requests one.
  • Input: Purified payload.
  • Stop Condition: If the brief exceeds one page, stop and compress the friction and leverage sections.
  • Validation: Brief matches §4 exactly; all unconfirmed facts labeled.

4. Output Specification

**[Company] - [Person, title] - [meeting date]**
_Meeting: [purpose] · [duration] · [attendees]_

**The 30-Second Read**

[Two sentences defining the core objective and primary focus area.]

**Stakeholder Intelligence**

- **Person:** [Role, decision-making style]
- **Company:** [Stage, size, relevant recent moves]

**Core Intent**

- [The stated request]
- [The underlying unstated interest]

**Friction Points**

- [Specific objection 1] -> [Why they will raise it]
- [Specific objection 2] -> [Why they will raise it]

**Leverage**

- [Advantage held by the user]

**Opening Move**

- [One concrete opening line or framing question]

5. Validation Gate

  • [ ] Both target identifiers explicit; at most one clarifying question asked.
  • [ ] Every claim traceable to a source tier; pasted-context conflicts resolved.
  • [ ] All unconfirmed details labeled "Unconfirmed."
  • [ ] Zero banned words, zero em dashes, one page or shorter.
  • [ ] Brief matches §4; user receives it in chat.

6. Anti-Triggers and Calibration

  • Under-execution threshold: Relying on web research alone when connected-tool data exists, or emitting a generic research dump.
  • Over-execution threshold: Generating a multi-page dossier, drafting a proposal, or scheduling the meeting.
  • Calibration default: Err toward brevity and connected-tool data over excessive web scraping.

7. Anti-Pattern Compliance

| Step | Prevents AP | Mechanism | | ----------- | ----------------------------------- | ---------------------------------------------------- | | 1 (Extract) | AP-1 (vague task verb) | Explicit company and person identifiers required. | | 2 (Sources) | AP-11, AP-12 (forgotten/no context) | Source-tier priority forces context capture. | | 3 (Payload) | AP-42 (no target state) | Stated vs inferred intent kept distinct and labeled. | | 4 (Purify) | AP-29 (ambiguous verb) | Deterministic writing-rules pass. | | 5 (Render) | AP-45 (no human review trigger) | Chat delivery keeps human in the loop. |

8. Versioning & Changelog

  • Version: 2.0.0
  • Changelog:
    • 2.0.0 (2026-08-09) — Elevated to Tier 5 per docs/skill-standard.md. Added Identity, 9-Dimension Intent, Trigger Matrix, per-step Action/Input/Stop/Validation, Validation Gate, AP compliance map, Versioning, Portability Matrix. Fixed mojibake corruption in the Output Specification header.

9. Portability Matrix

| Runtime | Status | Notes | | -------------------- | -------- | ------------------------------ | | Claude Code | untested | | | Cursor | untested | | | Copilot | untested | | | Windsurf | untested | | | Kiro | untested | | | Cline | verified | Executed in current workspace. | | Raw API (no tooling) | untested | |

10. Examples

Input: "Build a brief on John Smith at Acme Corp for our 2pm."

Output: A §4 brief with Acme Corp stage and size from web research, John Smith's role and decision style from CRM, stated intent from the calendar invite, friction and leverage items, and a single opening move. Any datum absent from all sources is labeled "Unconfirmed."

Failure case: The user asks for a 10-page dossier. Refuse: over-execution per §6. Deliver the one-page brief and offer a follow-up research pass.
