self-improving-systems

self-improving-systems is a skill for Claude Code, Codex from ooiyeefei/ccc. It costs 161 tokens per session (5,097 once invoked), scanned A, original, MIT.

A set of decision guides for determining whether an agent needs saved information, feedback loops, or learning from past results. It distinguishes temporary state or summaries from persistent memory.

In plain words
What is it for?
Use it when an agent forgets context, needs to retain information between tasks, or is being designed to improve from feedback.
Why use it?
It helps avoid adding long-term memory or learning systems when a simpler approach would solve the problem and be easier to control.

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-improving-systems 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 5d 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-Improving Systems

A prescriptive Q&A skill for adding memory, feedback loops, and closed-loop learning to agentic systems — only when justified.

Headline message: most agents shouldn't have persistent memory.

Memory is a liability surface (drift, poisoning, debugging difficulty, GDPR/HIPAA exposure). Persistent memory is the second move, not the first. The skill's job is to filter ruthlessly so the user doesn't ship a mem0/Letta build for a problem that a 200-line conversation summary would solve.

The first 2 stages of the Q&A flow exist to stop most users from over-engineering. By the end of stage 2, ~60% of users will discover they want a state cache (or stateless RAG), not memory + learning. That's the win.


Quick Start

User just asks:

"Add memory to my agent"
"My agent keeps forgetting things — give it context management"
"Make my marketing agent learn from past campaigns"
"Should I use mem0 or Letta?"
"How do I set up closed-loop learning for my finance agent?"
"Build a self-improving HAZOP system"

Skill response (every time, in this order):

  1. Stop. Apply the cache-vs-learning frame (Stage 1).
  2. Run the 6-question need-memory rubric (Stage 2). <4 yes → exit the skill, recommend stateless + RAG.
  3. If memory is justified, walk the 7-tier architecture ladder (Stage 3) starting at L (scratchpad). Escalate only when forced by a concrete justification.
  4. Force the user to design a feedback signal (Stage 4). No signal = state cache, full stop.
  5. Wire the closed loop with explicit human gates (Stage 5).
  6. Build the eval harness (Stage 6) — golden set, regression, drift alarms.
  7. Walk the 8-risk checklist (Stage 7).
  8. Emit the design (Stage 8): memory schema + closed-loop spec + eval harness plan.

Critical Rules

1. Default position: scratchpad-only

Ship a stateless agent first. Add a scratchpad (Reflexion-style verbal self-correction) within a single run. Discard it after. This already gets you most of the gain on most tasks. Anything more must be earned.

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.

self-improving-systems is a skill published in the GitHub repository ooiyeefei/ccc (483 stars, last pushed 1mo ago), licensed MIT. It adds 161 tokens to every session and 5,097 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
