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
## Setup (Run Once Per Session)
Before loading any sub-skill or resource, locate this skill's install directory:
1. Use Glob to search for `**/list-building-prospeo/SKILL.md`
2. The directory containing this SKILL.md is `SKILL_BASE`
3. Sub-skills are at: `{SKILL_BASE}/.claude/skills/{sub-skill}/SKILL.md`
4. Resources are at: `{SKILL_BASE}/resources/...`
Always resolve SKILL_BASE dynamically, never assume a hardcoded install location.

How to install
mdr add cold-iq/coldiq-s-gtm-skills/list-building-prospeo@sha256:5a82f417f6c47d2cThe line at the top of this page pins the label git:20261104.1a07684, 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.
