Memorize is an agent skill from NeoLabHQ/context-engineering-kit. Curates insights from reflections and critiques into CLAUDE.md using Agentic Context Engineering
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Context engineering and Agent instruction files. The repository describes itself as: Hand-crafted Claude Code Skills focused on improving agent results quality. Compatible with OpenCode, Cursor, Antigravity, Gemini CLI, and others. Includes CodeRabbit open-source… The licence is GPL-3.0.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 23e2428. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
arxiv.orgFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Memorize loads about 2.7k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 1,171 words of instructions outside code blocks.
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.
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); files beside SKILL.md are not scanned.

.claude/skills/memorize/SKILL.md (or your agent's skills folder).<role>
You are a memory consolidation specialist implementing Agentic Context Engineering (ACE). Your role is to capture insights from reflection and debate processes, then curate and organize these learnings into CLAUDE.md to create an evolving context playbook that improves future agent performance through structured knowledge accumulation.
</role>
<task>
Transform reflections, critiques, verification outcomes, and execution feedback into durable, reusable guidance by updating `CLAUDE.md`. Use Agentic Context Engineering (ACE) principles to grow-and-refine a living playbook that improves over time without collapsing into vague summaries.
</task>
<context>
This command implements the **Curation** phase of the Agentic Context Engineering framework:
- **Generation**: Initial solutions and approaches (handled by main conversation)
- **Reflection**: Analysis and critique of solutions (handled by /reflexion:reflect and /reflexion:critique)
- **Curation**: Memory consolidation and context evolution (this command)
Output must add precise, actionable bullets that future tasks can immediately apply.
</context>
First, gather insights from recent reflection and work:
/reflexion:reflect/reflexion:critiqueIf scope is unclear, ask: “What output(s) should I memorize? (last message, selection, specific files, critique report, etc.)”
Extract only high‑value, generalizable insights:
Prefer specifics over generalities. If you cannot back a claim with either code evidence, docs, or repeated observations, don’t memorize it.
# Read current context file
@CLAUDE.mdAssess what's already documented:
For each insight identified in Phase 1 apply ACE’s “grow‑and‑refine” principle:
Generation → Curation Mapping:
Example Transformation:
Raw insight: "Using Map instead of Object for this lookup caused performance issues because the dataset was small (<100 items)"
Curated memory: "For dataset lookups <100 items, prefer Object over Map for better performance. Map is optimal for 10K+ items. Use performance testing to validate choice."Ensure new memories don't dilute existing quality context:
Consolidation Check:
Specificity Preservation:
Organization Integrity:
If a potential bullet conflicts with an existing one, prefer the more specific, evidence‑backed rule and mark the older one for future consolidation (but do not auto‑delete).
Update the context file with curated insights:
CLAUDE.mdCreate the file if missing with these sections (top‑level headings):
Project Context
Code Quality Standards
Architecture Decisions
Testing Strategies
Development Guidelines
Strategies and Hard Rules
Place each new bullet under the best‑fit section. Keep bullets concise and actionable.
For each significant insight, add structured entries:
## [Domain/Pattern Category]
### [Specific Context or Pattern Name]
**Context**: [When this applies]
**Pattern**: [What to do]
```yaml
approach: [specific approach]
validation: [how to verify it's working]
examples:
- case: [specific scenario]
implementation: [code or approach snippet]
- case: [another scenario]
implementation: [different implementation]Avoid: [Anti-patterns or common mistakes]
Confidence: [High/Medium/Low based on evidence quality]
Source: [reflection/critique/experience date]
After updating CLAUDE.md:
Coherence Check:
Actionability Test: A developer should be able to use the bullet immediately
Consolidation Review: No near‑duplicates; consolidate wording if similar exists
Scoped: Names technologies, files, or flows when relevant
Evidence‑backed: Derived from reflection/critique/tests or official docs
Track the effectiveness of memory updates:
After effective memory consolidation:
# Memorize from most recent reflections and outputs
/reflexion:memorize
# Dry‑run: show proposed bullets without writing to CLAUDE.md
/reflexion:memorize --dry-run
# Limit number of bullets
/reflexion:memorize --max=5
# Target a specific section
/reflexion:memorize --section="Verification Checklist"
# Choose source
/reflexion:memorize --source=last|selection|chat:<id>CLAUDE.md was created/updated/reflexion:reflect: reflect → curate → memorize. https://arxiv.org/pdf/2510.04618). Remember: The goal is not to memorize everything, but to curate high-impact insights that consistently improve future agent performance. Quality over quantity - each memory should make future work measurably better.

Curates insights from reflections and critiques into CLAUDE.md using Agentic Context Engineering. Memorize is an agent skill from NeoLabHQ/context-engineering-kit.
Memorize fits situations like: tasks that involve Context engineering; tasks that involve Agent instruction files.
Run `npx skills add NeoLabHQ/context-engineering-kit --skill memorize -a claude-code`. Or copy the skill folder (skills/memorize in NeoLabHQ/context-engineering-kit) into .claude/skills/memorize in your project. Claude Code loads it when a task matches its description.
Run `npx skills add NeoLabHQ/context-engineering-kit --skill memorize -a codex`. Or copy the skill folder (skills/memorize in NeoLabHQ/context-engineering-kit) into .agents/skills/memorize in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add NeoLabHQ/context-engineering-kit --skill memorize -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/memorize, .gemini/skills/memorize, .github/skills/memorize and .opencode/skills/memorize in your project.
SKILL.md names no scripts, command-line tools or credentials: Memorize is instructions for the agent only.
SKILL.md names 1 domain. In commands or code: arxiv.org; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Memorize is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Memorize: Context Engineering (abashev/vfs-s3, 106 stars), Harness Engineering (10xChengTu/harness-engineering, 102 stars), Cc Dev Agent (sangrokjung/claude-forge, 852 stars) and Caveman Learn Token Fixes (JuliusBrussee/caveman, 111k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
