What it does

Self Improving Agent is an agent skill from YiShu5/claude-skills. Low-noise self-improvement skill. Captures learnings, errors, and corrections into a local .learnings/ cache layer. Never auto-promotes to long-term memory files (SOUL.md, MEMORY.md, AGENTS.md, TOOLS.md). Promotion requires explicit user approval after repeated validation.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `.learnings/ERRORS.md`, `.learnings/FEATURE_REQUESTS.md` and `.learnings/LEARNINGS.md`).

It sits in Agent Workflows, covering Agent memory and Agent instruction files. The repository describes itself as: Battle-tested coding-agent skills for product, content, writing, presentations, and workflow automation. The licence is MIT.

When your agent uses it

Tasks that involve Agent memory
Tasks that involve Agent instruction files

Example prompts

“/self-improving-agent”

Requirements

Python 3
A Bash shell

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

Write to cache first. All observations go to .learnings/. No exceptions.
Never auto-promote. The cache is not the system. Promotion is a deliberate act.
SOUL.md is sacred. Modifications require explicit human review every time.
MEMORY.md is for stable truths. Only long-term preferences, decisions, and goals belong there.
Errors and learnings stay separate. Different logs, different purposes.
Silence is better than noise. If unsure whether something is worth logging, don't log it.
No cross-session broadcasting of raw learnings. Only promote distilled, verified content.

What it can do on your machine

Read from SKILL.md and the folder at commit 38bd735. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Shell), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Self Improving Agent loads about 1.2k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~74
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Self-Improving Agent (Low-Noise Edition)

A conservative self-improvement system that treats .learnings/ as a write-first cache layer. Nothing reaches the main system files without human review.

Quick Reference

Action	Target	Auto?
Log a learning	`.learnings/LEARNINGS.md`	Yes
Log an error	`.learnings/ERRORS.md`	Yes
Log a feature gap	`.learnings/FEATURE_REQUESTS.md`	Yes
Promote to MEMORY.md	Requires user approval	No
Promote to SOUL.md	Requires user approval + review	No
Promote to AGENTS.md	Requires user approval	No
Promote to TOOLS.md	Requires user approval	No

Core Principles

Write to cache first. All observations go to .learnings/. No exceptions.
Never auto-promote. The cache is not the system. Promotion is a deliberate act.
SOUL.md is sacred. Modifications require explicit human review every time.
MEMORY.md is for stable truths. Only long-term preferences, decisions, and goals belong there.

No cross-session broadcasting of raw learnings. Only promote distilled, verified content.

Logging Format

Learning Entry

markdown

## [YYYY-MM-DD] Category: brief title

- **Type**: correction | knowledge_gap | best_practice
- **Context**: What was happening
- **Learning**: What was learned
- **Confidence**: low | medium | high
- **Promote?**: no (default) | candidate | promoted

Error Entry

markdown

## [YYYY-MM-DD] brief description

- **Command/Tool**: What failed
- **Error**: The error message or symptom
- **Root Cause**: What actually went wrong
- **Resolution**: How it was fixed
- **Recurrence**: first | repeated

Feature Request Entry

markdown

## [YYYY-MM-DD] brief description

- **Gap**: What capability is missing
- **User Need**: Why it matters
- **Priority**: low | medium | high

Promotion Gates

A cached item may be promoted to a system file only when ALL of these are true:

Repeated — The same insight has appeared in 2+ separate sessions
Verified — The insight was confirmed correct (not a one-off misunderstanding)
User-approved — The user explicitly agrees to promote it
Relevant long-term — It's not a temporary workaround or context-specific hack

Show full SKILL.md (149 more words)Show less

Promotion Targets

Content Type	Target File	Extra Requirement
User preference / long-term decision	MEMORY.md	Stable across sessions
Identity / behavior guideline	SOUL.md	Human review mandatory
Agent capability / role definition	AGENTS.md	Verified in practice
Tool usage pattern / integration	TOOLS.md	Tested and confirmed

Promotion Process

Agent proposes promotion with rationale
User reviews the exact content to be written
User explicitly approves
Agent writes to target file
Agent marks the cached entry as Promote?: promoted

Best Practices (Low-Noise)

Don't log obvious things. "Python needs indentation" is not a learning.
Don't log things already in the codebase or docs.
One entry per insight. No walls of text.
Prefer updating an existing entry over creating a duplicate.
Review .learnings/ periodically. Prune stale entries.
When in doubt, skip the log. You can always add it later.
