Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.01790 |
| Opus 5 | $0.00030 | $0.00895 |
| Sonnet 5 | $0.00012 | $0.00358 |
| Haiku 4.5 | $0.00006 | $0.00179 |
Grade B, and why
learn-and-improve scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Learn and Improve
Analyze friction in the current session and propose targeted improvements to Claude Code configuration.
Workflow
Step 1: Understand the Problem
Ask the user what went wrong. If they've already described the issue, confirm your understanding.
Use AskUserQuestion to clarify:
- What happened? (e.g., "skill X asked for permission to run Y")
- What should have happened? (e.g., "it should just run without asking")
- How often does this occur? (one-off vs recurring)
Step 2: Gather Diagnostic Context
Investigate the current configuration by reading these files (read only what exists):
Settings (permissions, hooks, env):
~/.claude/settings.json(user-level).claude/settings.json(project-level, shared).claude/settings.local.json(project-level, local)
Memory (CLAUDE.md hierarchy):
~/.claude/CLAUDE.md(user-level)./CLAUDE.mdor./.claude/CLAUDE.md(project-level)./CLAUDE.local.md(local overrides)./.claude/rules/*.md(modular rules)
Auto memory:
~/.claude/projects/*/memory/MEMORY.mdfor the current project
Plugins & skills:
.claude-plugin/marketplace.json(if in a plugin repo)- Installed plugins:
~/.claude/plugins/cache/(list directories) - Installed marketplaces:
~/.claude/plugins/marketplaces/(list directories)
MCP servers:
.mcp.json(project)~/.claude.jsonor~/.claude/mcp.json(user)
Also review the conversation history for:
- Tool calls that were blocked or required permission prompts
- Skills that were invoked (or should have been but weren't)
- Agents that were spawned and their outcomes
- Error messages or unexpected behavior
Step 3: Identify the Root Cause
Common root causes and their fixes — see Improvement Types for full details.
| Symptom | Likely Cause | Fix Location |
|---|---|---|
| Permission prompt for a bash command | Missing allow rule |
settings.json permissions.allow |
| Permission prompt for file read/write | Missing path pattern | settings.json permissions.allow |
| Skill not triggering | Bad description triggers | Skill SKILL.md frontmatter |
| Skill triggering on wrong tasks | Description too broad | Skill SKILL.md frontmatter |
| Repeated instructions ignored | Not in CLAUDE.md | CLAUDE.md (appropriate level) |
| Convention not followed per-filetype | No path-scoped rule | .claude/rules/ with paths frontmatter |
| Agent hitting permission walls | Agent lacks permissionMode |
Agent frontmatter |
| MCP tool requiring permission | Missing MCP allow rule | settings.json permissions.allow |
| Hook not firing | Wrong matcher or event | settings.json hooks |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 10d ago First seen · 145 lines · 61 tokens per session scan B 465e637380a5
learn-and-improve is a skill published in the GitHub repository dwmkerr/claude-toolkit (23 stars, last pushed 3d ago), licensed MIT. It adds 61 tokens to every session and 1,790 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
