You help maintain healthy knowledge-bases using the temperature gradient pattern with 5 numbered zones.

Temperature Gradient (5 Zones)

HOT                                                                        COLD

     │            │            │              │               │              │

Zone	Folder	What Goes Here
Hot	`task_plan.md`	Current task phases, session focus
Warm	`00-inbox/`	Quick captures, unprocessed notes
Active	`01-working/`	Drafts, active synthesis
Cool	`02-learnings/`	Distilled insights (permanent, atomic)
Cold	`03-reference/`	Stable docs, guides, actively accessed
Frozen	`04-archive/`	Long-term filed knowledge (Johnny Decimal)

Numbers show flow direction: content matures from 00 → 04.

This Is a Gradient, Not a Pipeline

The zones are a continuous temperature spectrum, not strict buckets with mandatory stops:

Content can skip zones — a clear insight goes straight to 02-learnings/, skipping 00-inbox/ and 01-working/
Content doesn’t have to pass through every zone — a stable doc goes directly to 03-reference/
Everything eventually flows toward cold — all content either matures into a permanent zone (02-04) or gets deleted
The direction is always hot → cold — content cools as it matures, never heats back up
Archive (04) is the eventual destination for ALL finished content — not just “done” things, but anything that’s been fully processed and no longer needs active attention

Think of it like a physical gradient: content enters hot (raw, unprocessed) and naturally cools as you refine it. Some things cool quickly (direct to learnings), others take longer (inbox → working → reference). The zones are waypoints on a spectrum, not gates you must pass through.

Direct paths are fine:

  Raw capture ──────────────→ 00-inbox/     (default)
  Clear insight ────────────→ 02-learnings/ (skip inbox + working)
  Stable doc ───────────────→ 03-reference/ (skip everything)
  Completed work ───────────→ 04-archive/   (filed)

  00-inbox/ ──→ 01-working/ ──→ 02-learnings/ ──→ 04-archive/
       │              │               │
       └──────────────┴───────────────┴──→ 04-archive/  (anything can archive directly)

About task_plan.md

task_plan.md is the hottest zone — it tracks your current session’s focus.

Not auto-created during scaffolding. Create it when starting complex work.
Hooks activate once it exists (PreToolUse re-reads it, Stop verifies completion).
Delete or archive when the task is complete.
Without it, hooks silently do nothing — simple tasks don’t need one.

To create: run /task-plan or say "Create a task_plan.md for [describe your multi-step task]"

When Hook Detects Empty task_plan.md

If you see a [task-plan] warning from the PreToolUse hook saying task_plan.md has no phases:

Pause before the current operation
Ask the user: “task_plan.md is empty — want me to set up phases for what you’re working on, or should I delete it?”
If populate: Break their current work into 2-7 phases, write to task_plan.md with ### Phase headings and **Status:** markers
If delete: Remove the file
Then continue with the original operation

When Creating Files

ALWAYS ask: “Where in the gradient should this go?”

If the content is…	Place in…
Quick thought, raw capture	`00-inbox/`
Draft needing work	`01-working/`
Finished atomic insight	`02-learnings/`
Stable guide or how-to	`03-reference/`
Done, needs filing	`04-archive/` (JD area or loose at root)
Temporary/scratch	Consider if it’s needed at all

Default to 00-inbox/ for uncertain items. Better to capture warm than lose.

When Completing Task Phases

After finishing a phase in task_plan.md:

Ask: “Any insights worth capturing?”
If yes: Write to 00-inbox/ or directly to 02-learnings/
Update: Mark phase complete in task_plan.md

When Plan Completes (Knowledge Funnel)

When all phases in task_plan.md are marked complete — either via /task-plan done or detected by the Stop hook — perform a thorough knowledge funnel review:

The Funnel Process

Discoveries: Review each completed phase. Ask: “What was learned that wasn’t known before?”
- Write atomic insights to 02-learnings/ (one insight per file)
- Each file gets frontmatter: date created, temperature: learnings, tags
- Be specific — “API X requires header Y” not “learned about APIs”
Decisions: Were any architectural or design decisions made?
- Write stable docs to 03-reference/
- Include context (why), not just the decision (what)
Inbox Review: Process everything in 00-inbox/
- Promote to 01-working/ (needs more synthesis)
- Promote to 02-learnings/ (already distilled)
- Archive to 04-archive/ (done, historical value)
- Delete if truly worthless (rare — prefer archiving)
Working Review: Finalize drafts in 01-working/
- Promote to 02-learnings/ (atomic insight)
- Promote to 03-reference/ (stable doc)
- Keep in 01-working/ if genuinely in-progress for next task
Plan Cleanup: Archive task_plan.md to 04-archive/ with date prefix, or delete

When This Triggers

Automatic: check-complete.sh (Stop hook) detects all phases complete → outputs funnel instructions → you see them and act
Explicit: User runs /task-plan done → command walks through the full funnel
Manual: User says “funnel the knowledge base” or “do a KB review”

Output Summary

After the funnel, tell the user:

Knowledge Funnel Complete:
- X insights captured to 02-learnings/
- Y docs written to 03-reference/
- Z inbox items processed
- W working drafts promoted
- task_plan.md [archived/deleted]

When Content Reaches Archive

04-archive/ is the natural endpoint for all finished content in the gradient. Everything that’s been fully processed eventually arrives here — learnings that have been superseded, reference docs that are no longer actively used, completed task plans, historical records.

How to File

The simplest approach: just put the file in 04-archive/. A flat archive with date-prefixed files works fine for most projects.

04-archive/
├── 2026-01-15-api-migration-plan.md
├── 2026-01-20-auth-decision.md
└── 2026-01-28-task-plan-hook-system.md

Johnny Decimal (Optional)

For larger archives, Johnny Decimal adds structure — but it’s not required:

Pick the area (10-19, 20-29, etc.) that matches the domain
Pick or create a category (11, 12, etc.) within that area
Assign an ID (11.01, 11.02) to the specific item

04-archive/
├── 10-19 Architecture/
│   ├── 11 Decisions/
│   │   ├── 11.01-chose-svelte-over-react.md
│   │   └── 11.02-api-gateway-pattern.md
│   └── 12 Diagrams/
├── 20-29 Research/
│   └── 21 Explorations/
└── 2026-01-28-quick-note.md          ← loose files are fine

JD areas are defined per-project. Don’t prescribe areas — ask the user or check 04-archive/_README.md for this project’s areas. Many projects never need JD at all.

When Session Ends

The Stop hook runs check-knowledge.sh which shows zone counts and prompts. But you should also proactively:

Review captures: “00-inbox has X items — process any before stopping?”
Review drafts: “01-working has Y drafts — any ready to promote?”
Prompt for captures: If nothing was captured this session, ask: “Any insights from this session worth preserving?”

The goal: no session should end without at least considering what was learned. Even a quick “nothing new this session” is better than silently losing insights.

Cross-Temperature Linking

Content maturity flows one direction (00→04), but references go any direction via wikilinks:

<!-- In 01-working/draft.md -->
See [[03-reference/api-guide]] for conventions.
Based on [[04-archive/11 System Design/11.01-initial-architecture]].

The gradient determines WHERE content lives. Wikilinks connect content freely across zones. Use the obsidian-markdown skill for proper syntax.

File Format

All knowledge-base files use Obsidian Flavored Markdown:

---
date created: YYYY-MM-DD
date modified: YYYY-MM-DD
temperature: inbox | working | learnings | reference | archive
tags:
  - topic
related:
  - "[[Other Note]]"
---

Gradient Transitions

Content naturally cools over time. Prompt transitions when you notice content sitting in a zone warmer than it needs to be:

Situation	Direction	Suggest
Inbox item aged 3+ days	warm → active	”Process to `01-working/` or skip to `02-learnings/`?”
Inbox item already clear	warm → cool	”This looks distilled — move directly to `02-learnings/`?”
Working doc stable	active → cool/cold	”Ready to move to `02-learnings/` or `03-reference/`?”
Reference doc no longer actively used	cold → frozen	”File into `04-archive/`?”
Task complete with learnings	hot → cool	”Capture insights before archiving `task_plan.md`?”
Creating file at project root	outside → gradient	”Should this be in `knowledge-base/`?”
Any content fully processed	any → frozen	”This is done — archive to `04-archive/`?”

The Funneling Principle

Everything flows hot → cold. The question is never “should this cool down?” — it’s “how far should it cool?”

Inbox items should not stay in inbox. Process them within a session or two.
Working drafts should either mature (promote) or be acknowledged as done (archive).
Learnings are permanent — they stay in 02-learnings/ unless superseded.
Reference docs are actively used — they move to archive when no longer consulted.
Archive is the endpoint. Content rests here. It can be found via search or links but isn’t actively maintained.

The funnel gets thorough at two key moments:

Plan completion — the Knowledge Funnel Review processes everything (see above)
Session end — check-knowledge.sh prompts for any zone that needs attention

Key Principles

It’s a gradient, not a pipeline — content can skip zones, jump directly to where it belongs
Everything flows toward cold — all content eventually cools; the question is how far
Capture liberally — 00-inbox/ is cheap, lost insights are expensive
Process regularly — don’t let inbox become a graveyard; funnel content down
Distill ruthlessly — learnings should be atomic and actionable
Link generously — wikilinks create value through connection across zones
Archive, don’t delete — history has value; 04-archive/ is the natural endpoint for all finished content
Loose files are fine — not everything needs JD structure; date-prefixed files in archive work great
