If time runs short, at least the high-priority items got processed. + +** Phase 2: Claude Rereads V2MOM + +Before processing any items, Claude rereads [[file:../EMACS-CONFIG-V2MOM.org][EMACS-CONFIG-V2MOM.org]] to have it fresh in mind. This ensures filtering decisions are grounded in the strategic framework. + +*What Claude should pay attention to:* +- The 6 Methods and their concrete actions +- The Values (Intuitive, Fast, Simple) and what they mean +- The Metrics (especially active todo count < 20) +- Method 6 discipline practices (ruthless prioritization, weekly triage, ship-over-research) + +** Phase 3: Process Each Item (in Priority Order) + +*IMPORTANT:* Process ONLY items under the "* Emacs Config Inbox" heading. Items already organized under Method 1-6 have been triaged and should remain where they are. + +For each item under "* Emacs Config Inbox", work through these questions: + +*** Question 1: Does this task need to be done at all? + +*Consider:* +- Has something changed? +- Was this a mistake? +- Do I disagree with this idea now? +- Is this actually important? + +*If NO:* **DELETE** the item immediately. Don't move it anywhere. Kill it. + +*Examples of deletions:* +- "Add Signal client to Emacs" - Cool idea, not important +- "Try minimap mode" - Interesting, doesn't serve vision +- "Research 5 different completion frameworks" - Already have Vertico/Corfu, stop researching + +*** Question 2: Is this task related to the Emacs Config V2MOM? + +*If NO:* **Move to** =docs/someday-maybe.org= + +These are tasks that might be good ideas but don't serve the current strategic focus. They're not deleted (might revisit later) but they're out of active consideration. + +*Examples:* +- LaTeX improvements (no concrete need yet) +- Elfeed dashboard redesign (unclear if actually used) +- New theme experiments (side project competing with maintenance) + +*** Question 3: Which V2MOM method does this relate to? + +*If YES (related to V2MOM):* + +Claude suggests which method(s) this might relate to: +- Method 1: Make Using Emacs Frictionless (performance, bug fixes, missing features) +- Method 2: Stop Problems Before They Appear (package upgrades, deprecation removal) +- Method 3: Make Fixing Emacs Frictionless (tooling, testing, profiling) +- Method 4: Contribute to the Emacs Ecosystem (package maintenance) +- Method 5: Be Kind To Your Future Self (new capabilities) +- Method 6: Develop Disciplined Engineering Practices (meta-practices) + +*This is a conversation.* If the relationship is only tangential: +- **Claude should push back** - "This seems tangential. Adding it would dilute focus and delay V2MOM completion. Are you sure this serves the vision?" +- Help Craig realize it doesn't fit through questions +- The more we add, the longer V2MOM takes, the harder it is to complete + +*If item relates to multiple methods:* +Pick the **highest priority method** (Method 1 > Method 2 > Method 3 > etc.) + +*IMPORTANT: Capture useful context!* +During discussion, Craig may provide: +- Impact estimates ("15-20 seconds Γ 12 times/day") +- Theories about root causes +- Context about why this matters +- Examples of when the problem occurs + +**When moving items to methods, add this context to the task description.** This preserves valuable information for later execution and helps prioritize work accurately. + +*Then:* Move the item to the appropriate method section in the V2MOM or active todo list with enriched context. + +** Phase 4: Verify and Celebrate + +Once all items are processed: +1. Verify "Emacs Config Inbox" heading is empty +2. Check that active todo count is < 20 items +3. Note the date of this triage session +4. Acknowledge: You've practiced ruthless prioritization (Method 6 skill development) + +** Decision Framework: When Uncertain + +If you're uncertain whether an item fits V2MOM: + +1. **Ask: Does this directly serve the Vision?** (Work at speed of thought, stable config, comprehensive workflows) +2. **Ask: Does this align with Values?** (Intuitive, Fast, Simple) +3. **Ask: Is this in the Methods already?** (If not explicitly listed, probably shouldn't add) +4. **Ask: What's the opportunity cost?** (Every new item delays everything else) + +*When in doubt:* Move to someday-maybe. You can always pull it back later if it proves critical. Better to be conservative than to dilute focus. + +* Principles to Follow + +** Claude's Role: "You're here to help keep me honest" + +Craig is developing discipline (Method 6: ruthless prioritization). Not making progress = not getting better. + +*Claude's responsibilities:* +- If task clearly fits V2MOM β Confirm and move forward quickly +- If task is unclear/tangential β **Ask questions** to help Craig realize it doesn't fit or won't lead to V2MOM success +- Enable ruthless prioritization by helping Craig say "no" +- Don't let good ideas distract from great goals + +*Example questions Claude might ask:* +- "This is interesting, but which specific metric does it improve?" +- "We already have 3 items in Method 1 addressing performance. Does this add something different?" +- "This would be fun to build, but does it make using Emacs more frictionless?" +- "If you had to choose between this and fixing org-agenda (30s β 5s), which serves the vision better?" + +** Time Efficiency: 10 Minutes Active Work + +Don't take too long on any single item. Splitting philosophical hairs = procrastination. + +*Target:* **10 minutes active work time** (not clock time - interruptions expected) + +*If spending > 1 minute on a single item:* +- Decision is unclear β Move to someday-maybe (safe default) +- Come back to it later if it proves critical +- Keep moving + +*Why this matters:* +- Weekly consistency requires low friction +- Perfect categorization doesn't matter as much as consistent practice +- Getting through all items > perfectly routing each item + +** Ruthless Prioritization Over Completeness + +The goal is not to do everything in the inbox. The goal is to identify and focus on what matters most. + +*Better to:* +- Delete 50% of items and ship the other 50% +- Than keep 100% and ship 0% + +*Remember:* +- Every item kept is opportunity cost +- V2MOM already has plenty of work +- "There will always be cool ideas out there to implement and they will always be a web search away" (Craig's words) + +** Bias Toward Action + +When processing items that ARE aligned with V2MOM: +- Move them to the appropriate method quickly +- Don't overthink the categorization +- Getting it 80% right is better than spending 5 minutes getting it 100% right +- You can always recategorize later during regular triage + +* Living Document + +This is a living document.
