What it does

Sight is an agent skill from cwinvestments/memstack. Use when the user says 'draw', 'diagram', 'visualize', 'architecture', or needs a visual overview of code structure.

Its SKILL.md is about 620 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 Development, covering Diagrams. It works with Mermaid. The repository describes itself as: Structured skill framework for Claude Code. 130 skills, persistent memory, TokenStack compression, localhost dashboard with 3-agent runner, real-time streaming, MCP tools. The licence is MIT.

When your agent uses it

The user says draw
Needs a visual overview of code structure

Example prompts

“diagram”
“visualize”
“architecture”
“/sight”

Workflow steps

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

Determine diagram type from context
Scan the relevant code
Generate Mermaid diagram as a code block
Optionally save to docs/diagrams/{name}.mermaid

What it can do on your machine

Read from SKILL.md and the folder at commit 00370ce. 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
No scripts in the folder and no shell commands in SKILL.md.
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

Sight loads about 621 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 182 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~31
When it runs · the whole SKILL.md, loaded when a task matches: ~621

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.

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.

👁️ Sight: The Hidden Becomes Clear

Generate Mermaid diagrams showing project architecture, schema, and data flow.

Activation

When this skill activates, output:

👁️ Sight: The hidden becomes clear.

Then execute the protocol below.

Context Guard

Context	Status
User asks for a diagram or visualization	ACTIVE: generate diagram
User says "draw", "diagram", "architecture"	ACTIVE: generate diagram
User asks to "show" or "map" the structure	ACTIVE: generate diagram
Discussing diagrams conceptually	DORMANT: do not activate
User is looking at existing diagrams	DORMANT: do not activate

Protocol

Determine diagram type from context:
- "database" / "schema" → erDiagram
- "api" / "endpoints" → flowchart TD
- "components" / "pages" → graph TD
- "architecture" / "structure" → flowchart TD (system overview)
- "flow" / "process" → sequenceDiagram
Scan the relevant code:
- For DB: read migration files in database/
- For API: list files in src/app/api/
- For pages: list files in src/app/
- For architecture: read package.json, directory structure, configs
Generate Mermaid diagram as a code block
Optionally save to docs/diagrams/{name}.mermaid

Inputs

What to visualize (database, API, components, architecture)
Project directory

Outputs

Mermaid diagram code block ready to render
Optional saved .mermaid file

Example Usage

User: "draw the AdminStack database schema"

👁️ Sight: The hidden becomes clear.

```mermaid
erDiagram
    accounts ||--o{ organizations : "has"
    accounts ||--o{ cc_sessions : "tracks"
    organizations ||--o{ projects : "contains"

    accounts {

Use when the user says 'draw', 'diagram', 'visualize', 'architecture', or needs a visual overview of code structure.

When should I use Sight?

Sight fits situations like: the user says draw; needs a visual overview of code structure.

How do I install Sight in Claude Code?

Run `npx skills add cwinvestments/memstack --skill sight -a claude-code`. Or copy the skill folder (skills/sight in cwinvestments/memstack) into .claude/skills/sight in your project. Claude Code loads it when a task matches its description.

How do I install Sight in Codex?

Run `npx skills add cwinvestments/memstack --skill sight -a codex`. Or copy the skill folder (skills/sight in cwinvestments/memstack) into .agents/skills/sight in your project. Codex loads it when a task matches its description.

Can I use Sight in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cwinvestments/memstack --skill sight -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sight, .gemini/skills/sight, .github/skills/sight and .opencode/skills/sight in your project.

What does Sight need to run?

SKILL.md names no scripts, command-line tools or credentials: Sight is instructions for the agent only.

Does Sight access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Sight safe to install?

Our automated static check of SKILL.md flagged 2 warning(s): contains zero-width characters. Read the flagged lines before installing; the check is not a guarantee either way.

What licence does Sight use?

Sight is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Sight use?

About 621 tokens (SKILL.md is roughly 2.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Sight?

Skills that share tags, products or a category with Sight: Archify Diagrams (tt-a1i/archify, 79k stars), Diagram Design (cathrynlavery/diagram-design, 45k stars), Draw.io Diagram Studio (Agents365-ai/drawio-skill, 10k stars) and Code Graph Mermaid Diagrams (trailofbits/skills, 7.4k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Sight?

cwinvestments (a GitHub user) maintains it in cwinvestments/memstack, which has 423 GitHub stars. The repository holds 87 skills in this directory. The repository was last updated on September 26, 2026.
