We split this skill into the rules it gives an agent

4 rules. About 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Write structured entries to memory/YYYY-MM-DD.md instead of free-form text.

    line 8
  2. Distinctive:

    After any meaningful action:

    line 12
  3. Very specific:

    Concepts are for search: Write keywords you'd use to find this entry later via memory_search.

    line 48
  4. Distinctive:

    One entry = one topic: Don't mix a decision + tool finding in one entry.

    line 50

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Structured Log

Write structured entries to memory/YYYY-MM-DD.md instead of free-form text. This improves recall via memory_search.

When to Use

After any meaningful action:

  • Made a decision or received a decision from the founder
  • Discovered a new fact (via Exa, PostHog, web, conversation)
  • Found an insight or pattern
  • Completed a task with a result
  • Updated a hypothesis

Entry Format

### HH:MM — [TYPE] Title

What happened (1-2 sentences).

**Facts:**
- concrete fact 1
- concrete fact 2

**Concepts:** keyword1, keyword2, keyword3
**Files:** path/to/file (if changed)

Types (TYPE)

TypeWhen
DECISIONDecision made (by whom, why, what changes)
FACTNew confirmed fact (source required)
INSIGHTPattern, connection, conclusion from data
TOOLFinding from tool usage (PostHog, Exa, web)
TASKCompleted task with result
HYPOTHESISCreated/updated/killed a hypothesis

Rules

  1. Facts must be verifiable. "Signups = 0 for 7 days" (ok). "Seems low" (no).
  2. Concepts are for search. Write keywords you'd use to find this entry later via memory_search. Include: names, products, metrics, topics.
  3. Files — only if changed. List only files that were created or modified.
  4. One entry = one topic. Don't mix a decision + tool finding in one entry.
  5. Narrative < 50 words. Context goes in facts, not prose.

Promotion to MEMORY.md

A fact deserves promotion to MEMORY.md if:

  • It changes understanding of wedge, ICP, constraint
  • It's confirmed 2+ times from different sources
  • It affects current strategy or hypothesis

On promotion — add to the appropriate MEMORY.md section and remove outdated info.

Example

### 14:30 — [TOOL] Analytics: 41% onboarding drop-off

Analytics query revealed a high drop-off rate during onboarding.

**Facts:**
- 41% of users who start onboarding don't complete the key activation step (30d)
- Main cause: timeout on large data imports
- Affects the signup -> activated funnel stage

**Concepts:** onboarding, activation-blocker, funnel-drop, analytics, TTFV

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
