1Trust14 / 25 · 2.8/5

The skill calls for anonymizing customer data when needed, obtaining seller approval, management fact review, and legal involvement for confidentiality and regulatory disclosures. It does not define least privilege, data flow, access isolation, retention/deletion, rollback, or external-effect controls, so points are deducted.

2Reliability8 / 20 · 2.0/5

The workflow, required inputs, document structure, formatting requirements, and review steps are internally consistent. However, there is no abnormal-input handling, failure feedback, dependency-availability guidance, or key-path test coverage; static calibration keeps this below 10.

3Adaptability10 / 15 · 3.3/5

The intended users, sell-side M&A scenario, trigger terms, and expected deliverables are clear. Non-fit boundaries, transaction-stage boundaries, Chinese-language behavior, and environment compatibility are not specified, so points are deducted. No explicit overseas online-service dependency is shown, so no additional network-reachability deduction is applied.

4Convention8 / 15 · 2.7/5

The documentation is readable and layered, with workflow guidance, output requirements, confidentiality notes, and limitations. Repository-level Apache-2.0 licensing, verified publisher provenance, and CI validation provide supporting governance evidence, but the skill lacks versioning, changelog, named maintenance responsibility, update path, installation/dependency notes, examples, and FAQs.

5Effectiveness7 / 15 · 2.3/5

It can organize company materials into a comprehensive CIM outline and specifies Word, Excel, chart, and review requirements. However, no templates, representative outputs, or verifiable generation mechanism are provided, limiting direct usability and comparative-benefit evidence; the static-calibration ceiling is 7.

6Verifiability4 / 10 · 2.0/5

The skill text is auditable, and the repository includes plugin-validation and secret-scanning workflows. There are no tests covering the CIM key paths, real execution results, or independent third-party corroboration, so only limited verifiability is awarded.

Before you use it
  • Do not treat the output as distribution-ready transaction material; management, legal counsel, and the deal team should verify facts, financial adjustments, confidentiality scope, and regulatory disclosures.
  • The skill does not define controls for accessing, storing, transmitting, or deleting sensitive materials; add data-governance controls in a controlled environment.
  • No reproducible DOCX/XLSX templates or test evidence are provided, so manual formatting and numerical review should be expected.
