Pressure-tests a plan into realistic timelines and delivery risks.
Part of the expert-intelligence-skills marketplace.
A forecast that separates the scope evidence from the schedule-risk drivers, then lands on a range rather than a single date — with the specific risks that would push you to the far end and what published estimation research says about each.
Output is grounded in what practitioners have actually published — every claim carries a citation back to the O'Reilly learning platform, and the skill is instructed never to cite a title, author, or link that didn't surface in its search.
Expand the path that matches your setup. Whichever you use, restart your session or app afterward so the new skill is picked up.

/plugin marketplace add oreillymedia/expert-intelligence-skills
/plugin install forecast-project-delivery@expert-intelligence-skills
Codex
For both the Codex CLI and Codex desktop, you must use the terminal to add the marketplace — run:

Manual: copy the file — works anywhere
Download SKILL.md with the Download raw file button, then:
- Claude desktop, web, or Cowork: open Customize → Skills, click Add → Upload
skill, and drop in the
.mdfile — it's accepted as-is, no zipping needed. One upload covers both Chat and Cowork. - Claude Code or Codex CLI: save it, filename unchanged, as
forecast-project-delivery/SKILL.mdinside~/.claude/skills/or~/.codex/skills/. This route is CLI-only — the desktop and web apps don't read those directories.
Important: When using this method you won't receive updates to this skill.
An O'Reilly learning platform account is required to search the library. When installed as a plugin, the O'Reilly Expert Intelligence MCP server is included automatically. If you copy an individual skill manually instead, connect the MCP server yourself; see the MCP guide for setup steps.
