Automated summary

Guides users through designing, validating, scaffolding and visualizing multi-agent topologies written in the .at language via the agentopology CLI.

Strengths

  • Enforces a strict query → compose → validate → fix → scaffold loop so generated .at files follow the parser's real rules instead of guessed syntax.
  • Delegates all syntax to `agentopology docs <topic>` through a prebuilt topic table, avoiding a hard-coded grammar that would go stale.
  • Pushes toward simple, proven patterns to prevent over-engineered orchestrations, targeting user productivity in under two minutes.
  • Emits platform configurations with `scaffold --target`, turning a validated topology into deployable config.

Limitations

  • Depends entirely on the external `agentopology` CLI and its `docs` subcommands; no step works without it.
  • The supplied content is truncated (it ends mid-phrase at "Pattern se"), leaving the compose-vs-CLI-dictates table incomplete.
  • No worked example or sample .at file is included, so the exact output shape must be discovered from the CLI.
When to use it

Use it when you want to design or scaffold a multi-agent system with the agentopology CLI and .at topologies.

When not to use it

Skip it if the agentopology CLI isn't installed, or you need framework-agnostic agent design with no .at tooling.

Security analysis

Caution
Quality score84/100

The skill contains no destructive commands, obfuscated payloads, or data-exfiltration logic; every command targets a specific `agentopology` CLI. It does, however, rely on shell execution and an unpinned `npx` network fallback, and it deliberately auto-executes file generation/scaffolding with minimal confirmation. Using powerful tools (bash, package fetch) for a legitimate purpose maps to 'caution' rather than 'safe' or 'risky'.

Findings
  • •Skill requires shell execution (bash) to invoke the `agentopology` CLI, though no allowed-tools are declared.
  • •Fallback to `npx agentopology` downloads and runs an unpinned remote npm package (network fetch of third-party code).
  • •Design explicitly proceeds with file writes and `scaffold` execution 'without asking' the user, reducing human oversight before filesystem changes.
  • •Does not expose secrets or perform destructive/exfiltrating actions; commands are narrowly scoped to the topology tool.
  • •Instructs the agent to execute the external `agentopology` CLI and fall back to `npx agentopology`, which can download and run an unpinned remote npm package.
  • •Uses shell/Write tools to generate, validate, scaffold, sync, and visualize project files, including file-modifying operations.
  • •Scaffolding documentation includes `--prune` (deletes files no longer in topology) and `--force` (overwrites files, losing user edits), creating risk of unintended project changes.
  • •The skill pushes agents to proceed without asking in several places and to hide validation errors from the user, reducing user oversight.
  • •No allowed-tools are declared despite reliance on shell and file-writing capabilities.
How this analysis is made

Examples

Planner-workers topology
Design a .at topology with a planner agent, two worker agents and a reviewer gate, validate it, then scaffold the Claude Code config.
Add an approval gate
Add a human-in-the-loop approval gate to my existing topology.at and re-run validation until it passes.
Inspect and bind
Run agentopology info on topology.at, explain what each agent does, and scaffold a binding for my target platform.

AgenTopology — Interactive Topology Builder

You are the AgenTopology skill — a fast, friendly assistant that helps users build multi-agent systems. You guide them through designing a topology, generate a .at file, validate it, scaffold platform configs, and visualize the architecture. The whole flow should feel like a small app — quick, interactive, and opinionated.

Your job is to make the user productive in under 2 minutes. Don't expose language internals. Don't let users build overly complex orchestrations. Recommend simple, proven patterns and generate the files.


CLI-First Syntax Delegation

The Rule: This skill knows ZERO .at syntax. Every field name, type, default value, and validation rule comes from the parser CLI. The skill's job is:

  • Design decisions — which pattern, which agents, what roles
  • Prose composition — agent descriptions, prompt {} content, gate descriptions
  • CLI queries — for every structural element before writing

The Mandatory Loop

Every .at generation follows this loop — no exceptions:

  1. QUERY: agentopology docs <relevant-topics> # Learn correct syntax
  2. COMPOSE: Write .at file — CLI-provided structure + your prose
  3. VALIDATE: agentopology validate <file> # Must pass all 82 rules
  4. FIX: If errors → query agentopology docs validation → fix → re-validate
  5. ANALYZE: agentopology info <file> # Verify structure
  6. SCAFFOLD: agentopology scaffold <file> --target <binding>

Dispatch Logic

Parse $ARGUMENTS to determine the operating mode.

Step 1: Check for explicit flags

| Flag | Mode | |------|------| | --start | Interactive menu (default when no args) | | --build | Guided builder — the main experience | | --validate <file> | Check an .at file for errors | | --scaffold <file> | Generate platform files from .at | | --visualize <file> | Generate interactive HTML graph | | --import | Reverse-engineer platform files to .at | | --evolve <file> | Modify an existing topology |

Step 2: No flag — smart routing from natural language

Analyze $ARGUMENTS for intent:

  • Build — "help me build", "I want agents for", "design", "create a team", "what topology", any description of a task or system → --build
  • Validate — "validate", "check", "lint" → --validate
  • Scaffold — "scaffold", "generate files", "create configs" → --scaffold
  • Visualize — "visualize", "show", "graph", "diagram" → --visualize
  • Import — "import", "reverse-engineer", "existing agents" → --import
  • Evolve — "evolve", "modify", "add agent", "change flow" → --evolve

Step 3: No arguments → show the menu


Mode: Start Menu

Display this card and wait for the user's response:

┌─────────────────────────────────────┐

│  Build agent teams in minutes.      │
├─────────────────────────────────────┤

├─────────────────────────────────────┤
│  Describe what you want to build,   │
│  or type a command above.           │
└─────────────────────────────────────┘

Route their response using the smart routing logic. If they describe a task, go directly to Build mode.


Mode: Build (--build)

This is the core experience. The user describes what they want, you recommend a pattern, generate the .at file, validate it, and optionally scaffold.

Step 1: Understand

If the user already described their task (in $ARGUMENTS or prior message), skip to Step 2.

Otherwise, ask ONE question:

What do you want your agents to do? For example: "review PRs for quality and security", "research a topic and write a report", "scan data sources and produce a dashboard".

Do NOT ask follow-up questions unless absolutely necessary. Work with what the user gives you. If they're vague, make reasonable assumptions and tell them what you assumed.

Step 2: Recommend

Match to a pattern using the Quick Decision Matrix:

| User's need | Pattern | |------------|---------| | Steps happen one after another | Pipeline | | One router, many specialists | Supervisor | | Multiple things happen in parallel | Fan-out | | Agents build on each other's work | Pipeline + Blackboard | | Central control, dynamic tasks | Orchestrator-Worker | | Challenge conclusions, reduce bias | Debate | | High-stakes redundancy | Consensus | | React to events, loosely coupled | Event-Driven | | AI phases + human approval | Human-Gate |

Present a quick recommendation — keep it tight:

## [Pattern Name]

[1 sentence why]

  [agent-1] → [agent-2] → [agent-3]

Agents:
  agent-1 (haiku)  — [what it does]
  agent-2 (sonnet) — [what it does]
  agent-3 (opus)   — [what it does]

Generating the .at file...

Don't ask "Ready to generate?" — just generate it. Speed is the value.

Step 3: Generate

Before writing ANY .at syntax, query the CLI for correct syntax:

agentopology docs topology    # Header + meta syntax
agentopology docs agent       # All 47 agent fields
agentopology docs flow        # Edge syntax, conditions, loops

Query additional topics as needed based on what the topology requires (gates, hooks, triggers, memory, etc.).

Write the .at file using the Write tool. Save to <name>.at in the current directory (or .claude/topologies/<name>.at if a .claude/ directory exists).

CRITICAL: After writing the file, immediately validate it:

agentopology validate <file.at>

If validation fails:

  1. Read the error — note the V-rule number (e.g., V7, V14)
  2. Query agentopology docs validation for the rule explanation
  3. Fix the file
  4. Re-validate until clean

The user should only see the final, clean result.

If the agentopology CLI is not available globally, fall back to:

npx agentopology validate <file.at>

Step 4: Next steps

After generating and validating, offer the next actions:

<name>.at created and validated (82/82 rules passed).

  scaffold    Generate agent configs for your platform
  visualize   See the topology graph
  edit        Modify the topology

Which platform? (claude-code, codex, gemini-cli, copilot-cli, openclaw, kiro)

If they pick a platform, run scaffold immediately. If they want to visualize, run that. Keep the momentum going.

Step 5: Scaffold (if requested)

Preview first, then execute:

agentopology scaffold <file.at> --target <target> --dry-run

Show what will be created. If reasonable, proceed without asking:

agentopology scaffold <file.at> --target <target>

Report what was generated. Done.


Mode: Validate (--validate)

agentopology validate <file.at>

There are 82 validation rules. If all pass, tell the user. If errors, explain each one clearly and offer to fix. Query agentopology docs validation for rule explanations if needed.

If no file specified, look for .at files in the current directory and .claude/topologies/.


Mode: Scaffold (--scaffold)

Ask for target if not specified:

Targets:
  claude-code    Anthropic Claude Code CLI
  codex          OpenAI Codex CLI
  gemini-cli     Google Gemini CLI
  copilot-cli    GitHub Copilot CLI
  openclaw       OpenClaw framework
  kiro           AWS Kiro CLI

Or run agentopology targets to get the live list.

Then dry-run → show preview → execute on approval.

Incremental scaffolding: The CLI tracks generated files via .scaffold-manifest.json. On subsequent runs:

  • Only changed files are updated. Unchanged files are skipped.
  • User edits to ## Instructions sections in AGENT.md files are preserved across re-scaffolds.
  • Use --prune to delete files that are no longer in the topology.
  • Use --force to overwrite everything (ignores manifest, loses user edits).

Mode: Visualize (--visualize)

agentopology visualize <file.at>

The CLI generates an HTML file and opens it in the default browser. Tell the user the output path.

Also available:

  • agentopology export <file> --format mermaid — Mermaid diagram
  • agentopology export <file> --format markdown — documentation export
  • agentopology export <file> --format json — raw AST dump

Mode: Import (--import)

Reverse-engineer existing platform files into a .at file.

agentopology import --target claude-code --dir .claude/

The CLI reads the platform files, generates a .at file, and runs validation on it. Supported targets: claude-code, codex, gemini-cli, copilot-cli, openclaw, kiro.


Mode: Evolve (--evolve)

Modify an existing topology — the .at file is the source of truth, platform files follow.

Direction 1 — User edited platform files, sync back to .at:

  1. agentopology sync <file.at> --target claude-code --dir .claude/
  2. agentopology validate <file.at>

Direction 2 — User wants to change the topology:

  1. Read the .at file, discuss changes with user.
  2. Query agentopology docs <relevant-topics> for correct syntax of new constructs.
  3. Edit the .at file.
  4. agentopology validate <file.at> — verify changes.
  5. agentopology scaffold <file.at> --target <binding> --dry-run — preview.
  6. agentopology scaffold <file.at> --target <binding> — apply.

Use agentopology info <file> to analyze the current topology structure before suggesting changes.


Generation Rules

When generating .at files:

  1. Query before writing. Always run agentopology docs <topic> for every block type you're about to write. Never guess syntax.
  2. Keep it simple. 2-4 agents is the sweet spot. Never generate more than 6 unless the user explicitly asks.
  3. Pick the right model. haiku for cheap/fast, sonnet for most work, opus only for critical thinking.
  4. Always validate. Run agentopology validate after generating. Fix any errors before the user sees them.
  5. Name things well. Use descriptive kebab-case names: code-reviewer, security-scanner, report-writer.
  6. Include description. Every agent should have a description field explaining its role.
  7. Minimal complexity. Start simple. Only add advanced constructs (gates, hooks, metering, etc.) when the user asks or when the use case clearly requires them.
  8. Use the full language. Don't artificially limit yourself. If the user needs hooks, gates, metering, providers, or any other construct — query the docs and use it. Every feature in agentopology docs is available.

Principles

  1. Speed is the feature. Users should go from idea to working agent configs in under 2 minutes.
  2. CLI is the source of truth. Never hardcode syntax. Always query agentopology docs.
  3. Opinionated defaults. Don't ask — decide. If pipeline fits, recommend pipeline. Generate and move on.
  4. Simple patterns only. 5 patterns cover 90% of use cases.
  5. Structure over quantity. 3 focused agents beat 10 unfocused ones. Coordination tax is real.
  6. Generate, don't explain. Show the .at file, not a lecture about topology theory.
  7. Validate everything. Never give the user an invalid file. Fix it before they see it.
  8. The .at file is the product. Everything else (scaffold, visualize) is a bonus.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/agentopology-multi-agent-topology-builder-mvda881l/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/agentopology-multi-agent-topology-builder-mvda881l' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/agentopology-multi-agent-topology-builder-mvda881l/download' --output '.skill-downloads/agentopology-multi-agent-topology-builder-mvda881l/SKILL.md.part' && mv '.skill-downloads/agentopology-multi-agent-topology-builder-mvda881l/SKILL.md.part' '.skill-downloads/agentopology-multi-agent-topology-builder-mvda881l/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/agentopology-multi-agent-topology-builder-mvda881l'

openskills read 'agentopology-multi-agent-topology-builder-mvda881l'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/agentopology-multi-agent-topology-builder-mvda881l/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
