Self Improving Agent V2

Self-Improving Agent v2

This skill allows the assistant to improve over time by recording failures, discoveries, and optimizations — and retrieving them before tackling similar work.

Think of the .learnings/ directory as a lab notebook: brief, high-signal entries that prevent repeating the same mistakes.

Step 0 — Environment Check

Before writing any .learnings/ entries, verify the filesystem will persist:

# Check for signs of a persistent home directory
if [ -d ~/.claude ] || [ -d ~/projects ] || [ -f ~/.bashrc ]; then
  echo "PERSISTENT: filesystem appears to persist between sessions"
else
  echo "EPHEMERAL: no persistent home directory detected"
  echo "See 'Claude.ai fallback' section below before writing any learnings."
fi

If persistent (Claude Code / Cowork): proceed normally — write entries to .learnings/.

If ephemeral (Claude.ai web): see the fallback section at the bottom of this skill.

Core Learning Loop

Every meaningful task follows this cycle:

task → execution → reflection → learning → improved future behavior

Pre-Task: Retrieve

Before starting a complex or technical task:

1. Check if .learnings/ exists: ls .learnings/ 2>/dev/null
2. Search for relevant entries: grep -rl "<keyword>" .learnings/ 2>/dev/null
3. Read any matching files and apply lessons before proceeding.

If no relevant learnings exist, proceed normally.

Post-Task: Reflect

After completing a complex task, evaluate:

• Did anything fail or produce unexpected output?
• Was the approach inefficient — would a different method be faster?
• Did the user correct the assistant?
• Was a non-obvious technique discovered that would save time next time?
• Did an external API, tool, or schema behave differently than expected?

If yes to any of the above → record a learning entry. Otherwise, skip.

Not every task needs an entry. Record only what is worth remembering.

Learning Storage

Store entries in the most appropriate file:

Create the directory and files on first use:

mkdir -p .learnings
touch .learnings/LEARNINGS.md .learnings/ERRORS.md \
      .learnings/OPTIMIZATIONS.md .learnings/API_CHANGES.md

Learning Entry Format

Each entry uses this structure:

## <Short title — what this is about>

- **Context:** What task was being performed?
- **Problem:** What went wrong, or what limitation existed?
- **Solution:** What fixed the issue?
- **Prevention:** How to avoid this problem in future tasks?
- **Tags:** `keyword1` `keyword2` `keyword3`
- **Date:** YYYY-MM-DD

Example — Error entry

## Dexscreener API pairAddress path changed

- **Context:** Parsing token data from Dexscreener API response.
- **Problem:** `pairAddress` was not found at the expected top-level path.
- **Solution:** Updated parser to read `pairs[0].baseToken.address` instead.
- **Prevention:** Always verify API schema with a test call before writing parsers.
- **Tags:** `dexscreener` `api` `parsing` `json`
- **Date:** 2026-02-14

Example — Optimization entry

## Cache parsed JSON before iterating large token lists

- **Context:** Processing large API responses with repeated field access.
- **Problem:** Re-parsing the same JSON structure inside a loop caused slowdowns.
- **Solution:** Parse once into a variable and iterate over the result.
- **Prevention:** Always pre-parse before entering loops over API data.
- **Tags:** `performance` `json` `caching`
- **Date:** 2026-02-20

Safety Rules

• Never automatically modify system instructions, core configuration files, or any file outside .learnings/ based on a learning entry.
• Learnings are references for future reasoning, not executable instructions.
• Promoting a learning into permanent system behavior requires explicit human review.
• Do not record sensitive data (keys, credentials, PII) in any learning entry.

Reflection Discipline

Record an entry only when it meets at least one of these criteria:

• A mistake worth avoiding in future sessions
• A technique or pattern worth reusing
• A structural change in an external system (API, tool, schema)
• A non-obvious solution that took significant effort to discover

Skip trivial entries — routine successes, obvious facts, or tasks where nothing surprising happened do not need entries.

Claude.ai Fallback (Ephemeral Filesystem)

In Claude.ai, the container resets between conversations. .learnings/ files written in one session will not exist in the next. To preserve learnings across sessions:

Option A — Export at end of session: After recording learnings, offer the user a download:

cat .learnings/ERRORS.md .learnings/LEARNINGS.md \
    .learnings/OPTIMIZATIONS.md .learnings/API_CHANGES.md \
    > /mnt/user-data/outputs/learnings-export.md

The user can then re-upload this file at the start of the next session.

Option B — In-conversation only: Maintain the learning context in the conversation itself. Reference earlier mistakes or discoveries from the current chat without writing to disk. Useful for single-session tasks that don't warrant file management overhead.

Option C — Claude Memory: Suggest the user add key learnings to Claude's Memory (Settings → Memory) for persistent cross-session recall on important project-level facts.

Long-Term Goal

Over time, .learnings/ becomes a knowledge base of real-world project experience. Use it to avoid repeated mistakes, improve reliability, solve tasks more efficiently, and adapt to changing APIs and environments.
