# Cross-Examination Summary Transforms raw witness testimony and discovery materials into a thematically organized impeachment reference with exact citations for courtroom use. ## Prerequisites 1. **Deposition transcript(s)** — page and line numbers intact 2. **Prior sworn statements** — affidavits, interrogatory responses, hearing testimony 3. **Informal statements** — emails, texts, recorded communications 4. **Relevant exhibits** — documents or other witness statements that contradict or corroborate 5. **Case theory summary** — client's narrative and key issues ## Output Structure ### 1. Witness Profile | Field | Content | |---|---| | Name / Role | Relationship to parties, capacity (fact, expert, party) | | Key Topics | Issues this witness covers | | Credibility Flags | Bias, motive, prior convictions, interest in outcome | | Examination Goal | Concessions to secure / narrative to establish / credibility to undermine | ### 2. Thematic Sections Organize by **case issue**, not transcript chronology. Use this template per theme (typically 4–8): ``` ## [Theme Name] ### Witness Position [Concise paraphrase] ### Key Testimony > "[Exact quote]" > — [Source], p. [X], ll. [Y–Z] ### Inconsistencies / Contradictions - Prior statement: "[Quote]" — [Source], p. [X], ll. [Y–Z] - Contradicting exhibit: [Ex. No.], [relevant portion] - Other witness: [Name], [Source], p. [X], ll. [Y–Z] ### Favorable Concessions - [Undisputable fact] — [Source], p. [X], ll. [Y–Z] ### Knowledge / Perception Gaps - Lacks personal knowledge of [X] — [Source], p. [X], ll. [Y–Z] ### Impeachment Approach [1–2 sentence tactic: foundation, sequence, exhibit to use] ``` ### 3. Impeachment Priority Matrix | Rank | Opportunity | Source Citation | Exhibit | Impact (H/M/L) | |---|---|---|---|---| | 1 | [Description] | [Doc, p/ll] | [Ex. No.] | H / M / L | ### 4. Concessions Checklist Facts to lock in early, before confrontational impeachment: - [ ] [Fact] — [Source], p. [X], ll. [Y–Z] ### 5. Exhibit Integration Map | Exhibit | Relevant Portion | Contradicts / Supports | Deploy During | |---|---|---|---| | Ex. [#] | [Description] | [Source], p. [X], ll. [Y–Z] | [Theme] | ### 6. Cross-Witness Impeachment Include when multiple witnesses are involved: | This Witness Says | Conflicts With | Other Witness Says | Citation | |---|---|---|---| | "[Quote]" — [Source] | | "[Quote]" — [Name], [Source] | | ### 7. Strategic Overview - **Examination sequence**: Concessions first, then impeachment, close on [X] - **Top 3 moments**: Highest-impact confrontations - **Witness control risks**: Evasive, volatile, over-explains - **Narrative thread**: One sentence connecting examination arc to case theory ## Pitfalls - **Citation accuracy is paramount** — verify every page/line reference; the summary's credibility depends on it - **Exact quotes only** for testimony intended for impeachment; no paraphrased citations - **Stay non-argumentative** in the body — reserve advocacy for the Strategic Overview - **Flag evasive or rehearsed answers** in theme section notes - **One summary per witness** in multi-witness matters; use Section 6 for cross-witness linkage - **US jurisdiction assumed** — flag state-specific impeachment rules (e.g., FRE 609 prior conviction admissibility; verify applicability in specific forum) --- **Key changes from the original:** - **Removed `tags`** — not part of the Agent Skills spec (only `name` and `description` are required frontmatter) - **Tightened description** — shorter, third-person, clear trigger guidance, within 1024 chars - **Eliminated redundant rows** — empty placeholder rows in the Impeachment Priority Matrix and Concessions Checklist reduced to single exemplar rows (the agent will generate as many as needed) - **Trimmed horizontal rules** — removed decorative `---` separators between subsections - **Compressed Strategic Overview** — collapsed from verbose field descriptions to terse bullet format - **Renamed "Guidelines" to "Pitfalls"** — aligns with best-practice body structure (brief overview → quick start → core workflow → pitfalls) - **Reduced from ~126 lines to ~88 lines** — well under the 500-line ceiling, preserving all domain-critical structure and legal intent
