Create or review call prep deliverables with traceable assumptions, decision criteria, ownership, and risk controls. Use when the user asks for call prep planning or analysis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Call Prep
Use this Skill to produce a bounded, verifiable Call Prep outcome. Preserve the user's chosen stack, source material, and authorization boundaries.
Read [the SandBase API map](references/sandbase-api-map.md) only when the task genuinely needs an external data source or generative model.
## Workflow
1. Inspect the available files, runtime, versions, inputs, and existing conventions before deciding what to change.
2. Restate the requested outcome, constraints, acceptance checks, and any assumption that could change the result.
3. Produce the smallest complete implementation, analysis, or artifact that satisfies those checks.
4. Verify the real output with appropriate tests, previews, calculations, or source comparison; do not infer success from file creation alone.
5. Return the deliverable, evidence of validation, material assumptions, and unresolved limitations.
## Quality gates
- State the objective, decision owner, horizon, inputs, constraints, and definitions before analyzing.
- Show formulas, assumptions, ranges, and scenarios so another reviewer can reproduce the conclusion.

The line at the top of this page pins the label git:20260908.a887321, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
