Skill Updater (Experience-to-Skill Diff)

Overview

skill-updater turns successful task execution into reusable skill improvements.

It reads the session log and daily memory, extracts new experience (what worked, new patterns, edge cases), identifies the most relevant skill files, and produces diff-formatted update suggestions for SKILL.md.

This skill follows NeuroClaw hierarchy:

• Defines WHAT to do, not low-level implementation details.
• Does not execute direct shell commands itself.
• Delegates any file scanning or execution via helper skills.

When to Call This Skill

• Task just finished successfully and user confirms "success".
• A tool returns a success status and experience should be recorded.
• Repeated tasks indicate missing instructions or edge-case guidance.

Core Workflow (Never Bypassed)

1. Read the session log and the relevant daily memory.
2. Extract new experience:
   • what worked
   • new patterns
   • edge cases solved
3. Identify the most relevant skill(s):
   • Use skill-creator to scan workspace/skills/ if available.
   • If not available, request a list of relevant skill files from the user.
4. Draft diff-formatted changes for the target SKILL.md:
   • Explicitly state: "New experience X: previously missing Y, now add Z."
   • Specify which sections change: instructions / examples / error handling.
5. Present a clear summary + patch to the user.

Required Output Format

Always include:

1. A concise summary list of new experience.
2. A target skill name.
3. A diff block for each proposed update.

Example output:

""" This successful task yields new experience:

1. ...
2. ...

Suggested update for skill xxx (diff):

@@
- Old line
+ New line

"""

Evidence Sources

• Session log (task execution trace)
• Daily memory (recent patterns and outcomes)

Safety and Execution Policy

• Never write changes directly; only propose diffs.
• Do not update unrelated skills.
• Do not invent results; only use observed success outcomes.
