excel

Handle spreadsheet operations (Excel/CSV) with high-fidelity modeling, financial analysis, and visual verification. Use for budget models, data dashboards, and complex formula-heavy sheets. Use proactively when zero formula errors and professional standards are required. Examples: - user: "Build an LBO model" - create Excel with banking-standard formatting - user: "Analyze this data and create a dashboard" - use openpyxl + artifacttool - user: "Verify formulas in this spreadsheet" - run recalc.py to check for errors

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/igorwarzocha/opencode-workflows --skill excel
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads excel automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

<instructions> <excel_professional_suite>

<modeling_standards>

  • Zero Formula Errors: Models MUST have zero #REF!, #DIV/0!, or #VALUE! errors.
  • Dynamic Logic: You MUST NOT hardcode derived values. You MUST use Excel formulas for all calculations.
  • Assumptions: You MUST place all inputs in dedicated assumption cells. </modeling_standards>

<professional_formatting>

  • Standards: Specify units in headers ("Revenue ($mm)"). Format zeros as "-".
  • Color Coding: The agent SHOULD follow the project's branding skill for color choices. If not defined, the agent SHOULD default to professional standards (e.g., Blue for hardcoded inputs, Black for formulas).
  • Visuals: You SHOULD use artifact_tool to render sheets and verify layout. Reference: references/artifact_tool_spreadsheets_api.md. </professional_formatting>

<technical_workflows>

1. Data Analysis (Pandas)

  • You SHOULD use Pandas for heavy lifting and aggregation.
  • You SHOULD convert to Openpyxl for final professional formatting and formula insertion.

2. Verification Loop (MANDATORY)

Before delivery, you MUST run the audit script:

  • python scripts/recalc.py output.xlsx
  • You MUST fix all errors identified in the resulting JSON summary. </technical_workflows>

<citation_logic>

  • Citations: You SHOULD cite sources for hardcoded data in cell comments.
  • Best Practices: See references/spreadsheet.md for guidance on cross-sheet references and complex formula construction. </citation_logic>

Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pgcron, pgmq), vector/semantic search (pgvector), and restoring dumps (pgrestore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.
