Monoshot is available wherever code is written. ⋅ Use the editor directly. ⋅ Keep source local with the CLI. ⋅ Let agents open, render, and share through the skill or MCP server. ⋅ Generate SVG, PNG, or shareable link through the hosted API.

Themes cover the entire image. Choose a wallpaper, gradient, color, or your own image, then Monoshot matches the syntax theme automatically. Adjust the frame, title bar, padding, radius, and width. Export to PNG or SVG, or copy a shareable editor link.

Monoshot's editor is type-aware. Hover JavaScript and TypeScript identifiers to inspect inferred types, see diagnostics while editing, and add type annotations directly to the image. Packages you import automatically get installed for type acquisition.

Annotations make code images easier to follow. Focus a line, highlight a block, show additions and removals, or add note, log, warning, and error callouts. Drag across lines to annotate a whole section in one pass. → monoshot.dev

Quick Prompt: "Read https://frog.⁠fm, and set up Frog in my project." GitHub: github.com/wevm/frog

The friction log manages itself. No stale lists. Frog can also report friction upstream to dependencies that opt in.

How it works: 1. Agent hits friction, runs `frog log` 2. Entry commits with the code that triggered it 3. Frog files a GitHub issue and comments on the PR 4. Issue gets fixed 5. Friction gets removed from entries Only unresolved friction survives.

GitHub: github.com/wevm/frog The problem: Agents are the best friction loggers you'll ever have, and the worst at keeping a log. Knowledge around workarounds is thrown away.

Docs should be agent-maintainable. Not trapped in a hosted CMS. Not detached from the code they describe. Vocs keeps docs and source together, so agents can inspect source, edit pages, update nav, run checks, and review the diff.

Lightweight docs save tokens. Every duplicated wrapper, noisy layout node, and unnecessary generated page competes with the actual context an agent needs. Vocs keeps the source compact while still allowing rich MDX, React, syntax highlighting, and custom UI.

Fast docs improve feedback. Readers should not wait for heavy JavaScript. Agents need quick responses while they iterate. Search engines need content that is fast to discover. Vocs combines Vite and waku.gg for hybrid server rendering and static generation.

Docs aren't just browser pages anymore. Agents use them to answer questions, write code, generate examples, inspect APIs, and change projects. Vocs makes docs an agent interface: Markdown pages with an embedded sitemap, plus MCP for lightweight context and seamless navigation.

Why is curl.md better than existing read_web_page/webfetch tools? curl.md resolves developer docs, API reference, GitHub issues/PRs, and more directly from their sources. Work smarter, not harder to get agent-friendly Markdown. See for yourself: curl.md/playground

Type safety isn’t just for humans. Agents building CLIs with incur get immediate feedback when they pass the wrong types. Schemas flow through generics so I/O are all fully inferred with zero manual annotations.

Without call-to-actions, agents guess what to do next, or worse, ask the user. incur CLIs tell the agent exactly which commands to run after each step, with the `cta` property.

Every token an agent spends reading output is a token it can't spend reasoning. incur defaults to TOON – ~40% fewer tokens than JSON, still human-readable format.

3,966
Every tool in an agent's context costs tokens, even when it's not being used. Agents using CLIs built on incur load skills on-demand and outputs TOON instead of JSON. Result: up to 3× fewer tokens per session. Good read: kanyilmaz.me/2026/02/23/cli-…

Agents attempting to discover or use a CLIs with vague context can produce inconsistent results. incur CLIs can register themselves as per-command skills. Zero manual skill crafting. Skills are kept up-to-date. Consumers just need to run `<your-cli> skills add`.

incur ships a minimal API so agents can build entire CLIs in a single pass. Three functions: `create`, `command`, `serve` – everything else is handled automatically. No tokens wasted on grokking complex public API surface.
