3ngram includes three prompt templates that orchestrate multiple tool calls automatically. Instead of running each tool manually, invoke a prompt and the AI handles the rest.

Briefing

Start-of-session overview. Gathers commitments, blockers, overdue items, stale work, and recent decisions.
“Run my briefing”
“Give me a briefing for the engram project”
What it does:
  1. Fetches all open commitments (including deferred)
  2. Checks for blockers
  3. Finds overdue items past their deadline
  4. Surfaces commitments with no activity in 7+ days
  5. Recalls recent decisions for context
Output is a structured summary with sections for Overdue, Blockers, Open Commitments, Stale items, and Recent Decisions, ending with a suggested focus area.
Argumentproject (optional)
Tools calledcommitments, blockers, overdue, stale_commitments, recall

Debrief

End-of-session extraction. Reviews the conversation and persists decisions, commitments, blockers, and learnings.
“Run my debrief”
“Debrief this session before I close”
What it does:
  1. Scans the conversation for decisions, commitments, blockers, and learnings
  2. Persists each as a structured memory with the right type and project tag
  3. Resolves any commitments completed during the session
  4. Summarizes what was captured
ArgumentsNone

Project Context

Deep dive into a single project. Retrieves everything scoped to one project in one pass.

  3. Checks for blockers and overdue items
