agent-platform-model-registry
Agent Platform Model Registry Management. Use when you need to upload, list, describe, update, or delete machine learning models (and their versions) in the Agent Platform Model Registry. Don't use for model training, model deployment to endpoints, or managing non-Agent Platform models.

# Agent Platform Model Registry Management
## Overview
This skill provides instructions for managing machine learning models in the
Agent Platform Model Registry. It covers listing models, describing model
details, uploading new models or versions, updating metadata, and deleting
models.
## Safety & Confirmation Tiers (CRITICAL)
Before executing any commands on behalf of the user, you MUST adhere to the
following safety tiers based on the action requested:
1. **Tier R: Read-only (`list`, `describe`, `get`)**
* No confirmation needed. Execute immediately to gather information.
2. **Tier M: Mutating & Reversible (`upload`, `update`)**
* Requires **interactive confirmation** with 'Yes'/'No' options. The
confirmation prompt MUST contain the exact, literal command string
with all required flags (e.g. `--region=us-central1`,
`--display-name="..."`) — natural-language paraphrases are NOT
sufficient.
* **Same-turn restriction**: NEVER execute the command in the same turn
as presenting the confirmation prompt. Stop and wait for the user's
reply; only execute after explicit 'Yes' / approval.
3. **Tier D: Destructive & Irreversible (`delete`)**
* Requires **explicit typed confirmation** (e.g. "I confirm" or "Yes,
delete it"). Ask for confirmation IMMEDIATELY — before any pre-flight
checks (don't check if the model is deployed to endpoints first).
* **Same-turn restriction**: NEVER execute in the same turn as asking
for typed confirmation. Wait for the user to reply in a new turn.
## Phase 0: Environment Setup
**CRITICAL**: Before running any commands, you MUST ensure the environment is
correctly initialized by following these steps:
1. **Google Cloud Authentication**: Authenticate with your Google Cloud
credentials and configure active Application Default Credentials (ADC) for
Agent Platform access:
```bash
gcloud auth login
gcloud auth application-default login
```
2. **Set Project**: Configure the active project for subsequent commands:
```bash
gcloud config set project $PROJECT_ID
```
3. **Region**: Always specify `--region=$LOCATION_ID` on each command below.
Do NOT use `global`.
## 1. Listing Models (Tier R)
Use this command to discover existing models in the registry and retrieve their
numeric IDs. No confirmation is required.
```bash
gcloud ai models list \
--region=$LOCATION_ID
```
## 2. Describing a Model (Tier R)
Retrieve the full metadata for a specific model or version. No confirmation is
required.
```bash
gcloud ai models describe $MODEL_ID \
--region=$LOCATION_ID
```
To target a specific version:
```bash
gcloud ai models describe ${MODEL_ID}@${VERSION_ID} \
--region=$LOCATION_ID
```
## 3. Uploading a Model (Tier M)
Register a new model or a new version of an existing model. This is a
long-running operation.
**Action requires an inline confirmation card before proceeding.**
### Example: Uploading a Custom Model
```bash
gcloud ai models upload \
--region=$LOCATION_ID \
--display-name="my-custom-model" \
--container-image-uri="gcr.io/my-project/my-model:latest" \
--artifact-uri="gs://my-bucket/path/to/artifacts"
```
> [!IMPORTANT] This is a Tier M operation — see [Safety & Confirmation Tiers]
> above.
To upload a new version of an existing model, use the `--parent-model` flag or
specify the parent model ID.
## 4. Updating a Model (Tier M)
Update metadata fields like display name, description, or labels.
**Action requires an inline confirmation card before proceeding.**
```bash
gcloud ai models update $MODEL_ID \
--region=$LOCATION_ID \
--display-name="new-display-name" \
--description="Updated description"
```
> [!IMPORTANT] This is a Tier M operation — see [Safety & Confirmation Tiers]
> above.
## 5. Deleting a Model (Tier D)
Permanently delete a Model and all its versions.
**Action requires explicit typed confirmation before proceeding.**
```bash
gcloud ai models delete $MODEL_ID \
--region=$LOCATION_ID
```
> [!WARNING] This operation is irreversible. All model versions must be
> undeployed from all Endpoints before deletion.

skill-development
IncludedComprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.
reprompter
IncludedTransform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.
adaptive-compaction
IncludedAdaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.
agent-skill-creator
IncludedCreate cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.
llm-wiki
IncludedUse when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.
skill-master
IncludedAgent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
