Discovery Catalog

Discovery Catalog

Compatibility

This skill is read-only and runs on Windows, macOS, and Linux through PowerShell. PowerShell 7+ (pwsh) is recommended for consistent table rendering, though the dispatcher also works in Windows PowerShell 5.1 with less polished wrapping.

Overview

Read-only inventory of the Discovery catalog repo. One dispatcher script (scripts/discovery-catalog.ps1) supports list and item-inspection invocations:

| Invocation | What it lists |

|---|---|

| discovery-catalog publishers | Every publisher across agents/ and starter-kits/, with per-publisher agent and starter-kit counts |

| discovery-catalog agents | Every agent in the catalog (one row per agent folder name) |

| discovery-catalog agents list-tools | Every agent plus the tools shipped under each agent's tools/ folder |

| discovery-catalog starter-kits | Every starter kit (one row per kit folder name) |

| discovery-catalog <agent-name> describe | One agent with Name, Publisher, Version, HasTool, Description |

| discovery-catalog <starterkit-name> describe | One starter kit with Name, Publisher, Version, Category, AgentCount, Description |

| discovery-catalog <agent-name> list-tools | One agent with Agent, Publisher, Version, ToolCount, Tools, Description |

Repo layout the script handles

The catalog uses a flat layout — one folder per agent or starter kit directly under the parent directory:

| Asset | Path pattern | Display |

|---|---|---|

| Agent | agents/<agent-name>/ | <agent-name> |

| Starter kit | starter-kits/<kit-name>/ | <kit-name> |

| Tool under an agent | agents/<agent>/tools/<tool-name>/ | <tool-name> |

Inclusion rules:

• An "agent" is any folder containing an agent.yaml.
• A "starter kit" is any folder containing a kit.json.
• Folders without those files (shared helpers, README-only directories) are silently skipped.
• The agents/tmp/ scratch directory used by the deployer skills is always skipped.

Publisher and party come from the asset's metadata, not from the folder location:

• For an agent: metadata.yaml → publisher.name (publisher) and publisher.party (1p / 3p).
• For a starter kit: kit.json → author.name (publisher) and the top-level party field.

If publisher.name / author.name is missing, the publisher is reported as (unspecified).

When to Use

Use this skill whenever the user wants to know what is in the catalog. Trigger phrases include but are not limited to:

• *"What agents are in this repo?"* / *"List the agents"* / *"Show me the catalog"*
• *"Who are the publishers?"* / *"Which partners have agents?"*
• *"What starter kits do we have?"* / *"List the starter-kits"*
• *"Show me agents with their tools"* / *"List tools per agent"*
• *"Do we have an agent for retrosynthesis?"* (use -Tag retrosynthesis)
• *"Which agents are missing a tool?"* (use -WithoutToolsOnly)
• Before invoking discovery-services-agent-deployer, when the user isn't sure of the exact agent folder name

Inputs

The skill is fully read-only and needs no Azure config. All inputs are positional or named parameters on scripts/discovery-catalog.ps1.

| Parameter | Position | Description | Default |

|---|---|---|---|

| Command | 0 (mandatory) | publishers, agents, starter-kits, or an agent/starter-kit name | — |

| SubCommand | 1 (optional) | list-tools (with agents or <agent-name>) or describe (with <agent-name> / <starterkit-name>) | empty |

| -Format | named | Table, Markdown, Json, or Plain | Table |

| -Publisher | named | Filter by publisher name (case-insensitive). Applies to agents and starter-kits | all |

| -Tag | named | Filter agents whose metadata.yaml includes this tag (agents only) | all |

| -WithToolsOnly | named | Only show agents that ship a tools/ folder (agents only) | off |

| -WithoutToolsOnly | named | Only show agents missing a tools/ folder (agents only) | off |

Invalid combinations exit with a non-zero code and a friendly message (e.g. agents foo, publishers list-tools).

Process

Mapping /discovery-catalog ... requests to invocations

When the user types a slash-style invocation like /discovery-catalog publishers, run the dispatcher with the matching arguments:

| User says | Run |

|---|---|

| /discovery-catalog publishers | pwsh -NoProfile -ExecutionPolicy Bypass -File .github/skills/discovery-catalog/scripts/discovery-catalog.ps1 publishers |

| /discovery-catalog agents | ... discovery-catalog.ps1 agents |

| /discovery-catalog agents list-tools | ... discovery-catalog.ps1 agents list-tools |

| /discovery-catalog starter-kits | ... discovery-catalog.ps1 starter-kits |

| /discovery-catalog <agent-name> describe | ... discovery-catalog.ps1 <agent-name> describe |

| /discovery-catalog <starterkit-name> describe | ... discovery-catalog.ps1 <starterkit-name> describe |

| /discovery-catalog <agent-name> list-tools | ... discovery-catalog.ps1 <agent-name> list-tools |

Use -Format Table for all catalog responses. Only add -Format Markdown if the user explicitly asks for a paste-ready markdown table.

When the dispatcher output is long, gather the full result before replying; never mention internal transport details, truncation, temp files, or resource files to the user.

Always return the complete table for the requested command; do not shorten it to a partial list or a narrative summary.

In chat responses, present tabular results as Markdown tables for readability, while keeping the count anchor line (*_COUNT=) above the table.

How the dispatcher works (internal — for skill maintainers)

• Resolve repo root via git rev-parse --show-toplevel.
• Walk agents/ and/or starter-kits/ one level deep, skipping tmp/.
• Inclusion: agent folders need agent.yaml; starter-kit folders need kit.json.
• For each entry, parse the appropriate metadata file:
• Agent: metadata.yaml for name, version, description, tags, plus the nested publisher.name and publisher.party.
• Starter kit: kit.json for name, version, description, category, party, author.name, plus top-level agentRefs; treat the role: primary entry as the launch agent.
• Tool (when agents list-tools): tool.yaml for name; folder name as fallback.
• Apply filters: -Publisher, -Tag, -WithToolsOnly, -WithoutToolsOnly.
• Sort by name (and publisher where applicable).
• Render in the requested format.

The first line of Table and Markdown output is a deterministic count anchor (AGENT_COUNT=, PUBLISHER_COUNT=, STARTER_KIT_COUNT=) so callers can grep for it.

Guidelines

• Read-only: never writes to the repo or to Azure. Safe to run repeatedly.
• Display name is the folder name — agents and starter kits are shown by their flat-layout folder name; publisher is rendered as a separate column populated from metadata.yaml/kit.json.
• Folder names are globally unique in the flat layout, so <agent-name> alone is enough to disambiguate.
• Command examples use PowerShell 7+ (pwsh) and work on Windows, macOS, and Linux when PowerShell is installed.
• Always include the count anchor (PUBLISHER_COUNT=, AGENT_COUNT=, STARTER_KIT_COUNT=) in Table/Markdown output so downstream automation has a deterministic anchor.
• Prefer tabular output for every catalog query; do not use Json or Plain for normal discovery responses.
• Return the full table for the requested command; never replace rows with a summary, excerpt, or placeholder text.
• Render user-facing tables in Markdown so columns remain aligned in chat.
• Never narrate internal handling such as reading from a resource file or hitting a terminal output limit.
• Don't crash on missing metadata — entries with missing metadata.yaml or unparseable kit.json are silently skipped (kits) or shown with empty fields (agents). Missing publisher.name is rendered as (unspecified).
• Don't list agents/tmp/ — it's the scratch tree used by other skills (discovery-services-agent-deployer) and is gitignored.
• PS 7+ recommended so Format-Table -AutoSize -Wrap renders long descriptions cleanly. The script works in Windows PowerShell 5.1 too but wrapping is uglier.
• Invalid subcommands exit with non-zero code and a friendly message — the dispatcher rejects e.g. agents foo or publishers list-tools.
