Use this skill when measuring, comparing, or projecting the real cost of a Gemini API prompt, reducing a Gemini bill, choosing between Gemini models on price, tuning thinking_level, or working out why a Gemini bill is higher than the visible output suggests.…

Use this skill when building deterministic agent workflows with Google ADK, routing between nodes with plain Python instead of letting the model decide, or adding a human approval gate that suspends a running agent until a person answers. Covers the ADK 2.0…

Use this skill when you want to treat agent system prompts like build artifacts instead of one giant hand-edited file. Covers authoring modular prompt fragments, transpiling them into a single rendered golden file with Jinja2, build-time validation for…

Use this skill when evaluating agent memory options, when running or reviewing the always-on memory agent sample (Google generative-ai repo, by Shubham Saboo), or when deciding between a self-hosted memory loop and the managed Vertex AI Memory Bank. Covers…

Use this skill when governing an AI agent's tool calls with a plain-English policy on Google's Gemini Enterprise Agent Platform, using Semantic Governance Policies (SGP). Covers deploying an ADK agent to Agent Runtime behind the Agent Gateway with agent…

Use this skill when adding on-device semantic search, FAQ matching, deduplication, clustering, or RAG reranking to a JavaScript or TypeScript app with no server, no API key, and no runtime model download. Covers the @ternlight/base and @ternlight/mini WASM…

Use this skill when running untrusted or model-generated code safely on Google Cloud Run, building an AI code interpreter, or letting an agent execute Python it wrote without exposing your service credentials. Covers deploying a Cloud Run service with the…

Use this skill when running Google's AlphaEvolve, the Gemini-powered evolutionary coding agent, to discover or optimize an algorithm on Google Cloud. Covers wrapping a function in EVOLVE-BLOCK markers, writing a scoring function, driving the controller loop…

Prepare a finished feature for review — clean the worktree, rebase on the base branch, resolve conflicts, and open or update a GitHub pull request linked to the Linear issue. Use as the final shipping step once implementation is complete and the user wants to…

Autonomously execute an approved implementation plan from a Linear issue — write code, run tests, commit changes, and check off tasks in Linear. Use when the plan is ready and the user wants to build the feature or fix end to end, isolating the work in a…

Refine a rough feature request or bug report into a structured PRD or Bug Brief inside a Linear issue. Use at the start of the engineering workflow to define and clarify what to build before any planning or coding — e.g. when the user wants to write a PRD,…

Generate a detailed implementation plan with parent tasks and atomic sub-tasks from the PRD in a Linear issue, syncing it to a

Generate a narrative summary and visual storyboard (browser screenshots) of completed changes and sync it to the Linear issue. Use after implementation to produce a human-readable walkthrough and visual proof of what was built for reviewers and stakeholders.

Manages Git worktrees for isolated parallel development. Creates branches (linking ticket IDs if available), copies local environment files, and pushes changes to the remote.

Lightweight skill to capture solved problems and learnings into simple markdown files

The full Loop Runner lifecycle, interactively — GCP infra setup, first canary run, authoring new loops (interview-driven), local dry-runs, deploys and triggers (cron / GitHub event / manual), cost tracking, and querying past runs. Use when the user wants to…

A template example of a per-loop skill. Use this to describe custom scripts, tools, or runbooks specific to this loop that the agent can execute.

Authoritative reference for the Agentic Resource Discovery (ARD) specification — the open, federated, domain-anchored standard (by Google, Microsoft, Hugging Face and others) for cataloging, discovering, and searching agentic resources (MCP servers, A2A…
