ai-agents-workspace-starter: Skill for Claude Code

.agents/skills/self-improvement/SKILL.md

self-improvement is a skill for Claude Code, Codex from systemowiec/ai-agents-workspace-starter. It costs 28 tokens per session (559 once invoked), scanned A, original, MIT.

A review workflow for capturing lessons after a substantial coding session. It looks for recurring mistakes, useful patterns, missing project context, and repeatable workflows.

In plain words
What is it for?
Use it after a feature, refactor, or other major work session to suggest updates to project notes, known pitfalls, skills, context files, or workflows.
Why use it?
It helps preserve knowledge that would otherwise be forgotten after the session. Proposed changes are shown for review instead of being added automatically.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is systemowiec/ai-agents-workspace-starter's own configuration. It tells Claude Code and Codex how to work on ai-agents-workspace-starter itself, so it is not a mod to install elsewhere.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

self-improvement scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Self-Improvement - Progressive Learning

Overview

The agent analyzes work performed and proposes improvements to the project configuration. NEVER adds automatically - always presents proposals for review.

When to Use

  • After completing a major work session (new feature, refactor)
  • When the user runs /self-improvement
  • When the agent discovers a repeatable pattern or pitfall

When NOT to use:

  • During implementation (focus on the task)
  • For trivial changes (one file, small fix)

Process

1. Gather context

Read:

  • docs/specs/ - recent implementation reports
  • .agents/learnings/gotchas.md - current state of knowledge
  • Recent commits (git log -10 --oneline)
  • Changed files in recent commits

2. Identify possible improvements

Type Goal Where to save
Gotcha Pitfall, unexpected behavior .agents/learnings/gotchas.md
Pattern Repeatable code pattern .agents/skills/<new-skill>/SKILL.md
Context update New model, endpoint, module .agents/context/*.md
Workflow Repeatable process .agents/workflows/<new>.md

3. Format proposals

For each proposal provide:

### [Type]: [Short title]

**Context**: Where/when this occurs
**Problem**: What happened or what is repeatable
**Proposal**: What to add/change
**File**: [file path]

4. Present to the user

  • NEVER add automatically
  • Present the list of proposals
  • Wait for approval of each one separately
  • After approval - add to the appropriate files (in the same commit)

Gotcha Entry Template

### [short title]
**Context**: [where/when this occurs]
**Problem**: [what happened]
**Solution**: [how to fix it]
**Date**: [YYYY-MM-DD]

**Observation**: [what is repeating]
**Example 1**: [where it occurred]
**Example 2**: [where it occurred]

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
