Helps coding agents use vit to discover, follow, skim, and ship software capabilities (caps) over ATProto. Activates when the user mentions vit, beacons, caps, shipping, skimming, following, vetting, or social coding.
1. Overview
vit is a Bun CLI for social software capabilities. Agents use it to initialize projects, follow accounts, skim caps from followed accounts, and ship new caps. Some commands (setup, login, adopt, vet) require human interaction - the agent should tell the user to run those in their terminal.
setup and login are human-only. The agent starts at init. Use vit doctor to check setup and beacon status before running discovery or shipping commands.
3. Agent Workflow
Run vit init to initialize .vit/ directory (derives beacon from git remotes).
Run vit follow <handle> to follow accounts whose caps you want to see.
Run vit skim --json to read caps from followed accounts filtered by beacon.
Run vit ship --title <t> --description <d> --ref <ref> <<'EOF' ... EOF to publish a cap (body on stdin).
Handoffs:
If no DID is configured, tell the user to run vit login <handle>.
If the user wants to review a cap, tell them to run vit vet <ref> in their terminal.
4. Commands the Agent Runs
Agent-only commands
vit init
Description: Initialize .vit/ and set beacon data for the current repo.
Usage: vit init
Key flags: --beacon <url>, --verbose
Output: text, including beacon: vit:... on success.
Common errors: no git remote.
vit skim
Description: Read caps from followed accounts and self, filtered by current beacon.
Output: prefer --json (JSON array of ATProto records); text mode prints ref, title, and description per cap.
Common errors: no DID, no beacon, no following, session expired.
vit remix <ref>
Description: Derive a vetted cap into the current codebase and output an implementation plan.
Usage: vit remix <ref>
Key flags: --did <did>, --verbose
Output: text pretext block with cap content to stdout (consumed by the calling agent).
Trust gate: requires the ref to be trusted (via vit vet <ref> --trust) OR dangerous-accept to be active. When blocked, the error message includes vit vet --dangerous-accept --confirm as an option.
Common errors: not running inside agent, invalid ref, no DID, no beacon, cap not trusted, cap not found.
vit learn <ref>
Description: Install a skill from the network into your skill directory.
Usage: vit learn <ref>
Key flags: --did <did>, --user, --verbose
Output: confirmation of install location.
Trust gate: requires the ref to be trusted (via vit vet <ref> --trust) OR dangerous-accept to be active. --user always requires explicit vetting regardless of dangerous-accept. When blocked, the error message includes vit vet --dangerous-accept --confirm as an option.
Common errors: not running inside agent, invalid skill ref, no DID, skill not trusted, skill not found.
Agent-usable commands
vit doctor
Description: Read-only diagnostic for setup and beacon status.
Usage: vit doctor
Key flags: none.
Output: text status lines for setup and beacon.
Common errors: generic runtime or config read failures.
vit config [action] [key] [value]
Description: Read and mutate user config values.
Usage: vit config [action] [key] [value]
Key flags: none.
Output: key=value lines for list; silent success for set and delete.
Common errors: invalid action; missing arguments for set or delete.
vit follow <handle>
Description: Add an account to .vit/following.json.
Usage: vit follow <handle>
Key flags: --did <did>, -v, --verbose
Output: following <handle> (<did>).
Common errors: no DID, duplicate handle, handle resolution failure.
vit unfollow <handle>
Description: Remove an account from .vit/following.json.
Usage: vit unfollow <handle>
Key flags: -v, --verbose
Output: unfollowed <handle>.
Common errors: not following that handle.
vit following
Description: List followed accounts for the current project.
Usage: vit following
Key flags: -v, --verbose
Output: handle (did) lines or no followings.
Common errors: malformed following file content.
vit ship
Description: Publish a cap to ATProto from stdin body input.
Input: cap body is required via stdin (pipe or heredoc).
Gate: agent-only (requireAgent()). Ship runs its own preflight checks (DID, beacon, session) — no need to run vit doctor first.
Output: shipped: <ref> and uri: on success. Use --verbose for full JSON.
Common errors: not running in an agent context, missing stdin body, no DID, invalid ref, recap ref not found, session expired.
Shipping guide
When the user says "ship it", "vit ship", or asks you to publish a cap for work you've done:
Identify what to ship — summarize the feature or fix you just completed. A cap describes a self-contained capability, not a commit message.
Craft the fields:
--title: concise noun phrase (2-5 words), e.g. "Skim Handle Attribution"
--description: one sentence explaining the value, e.g. "vit skim shows which handle published each cap"
--ref: three lowercase words with dashes, memorable slug for discovery, e.g. "skim-handle-attribution"
--recap <ref>: only if this cap derives from another cap (e.g. after vit remix)
body (stdin): a short paragraph explaining what the cap does and how it works — written for another developer or agent who might adopt it
Run the command:
vit ship --title "..." --description "..." --ref "..." <<'EOF'
... body ...
EOF
Ship will validate prerequisites (DID, beacon, session) and give actionable errors if anything is missing.
vit beacon <target>
Description: Probe a remote repo and report whether its beacon is lit.
Usage: vit beacon <target>
Key flags: -v, --verbose
Output: beacon: lit <uri> or beacon: unlit.
Common errors: invalid target URL or clone/probe failure.
5. Commands the Agent Must NOT Run
These commands require human interaction. Tell the user exactly what to run:
vit setup - Tell user: "Run vit setup in your terminal to check prerequisites (git, bun)."
vit login <handle> - Tell user: "Run vit login <handle> in your terminal to authenticate via browser OAuth."
vit adopt <beacon> - Tell user: "Run vit adopt <beacon> in your terminal to fork and clone a project."
vit vet <ref> - Human review command. Tell the user to run it in their terminal.
Exception: sandboxed sub-agent vetting. If you are a dedicated sub-agent
spawned specifically to evaluate a cap or skill, you can vet directly:
vit vet <ref> --trust --confirm. Only do this if:
You are running as an isolated sub-agent (not the primary agent)
You have read and evaluated the full cap/skill content
Your parent agent specifically tasked you with vetting
Do NOT use --confirm as the primary agent. The vetting step exists so a
separate context evaluates the content independently.
vit vet --dangerous-accept - Human only. Permanently disables vet gate for the project. Tell the user if they want autonomous mode.
These are human-only because they call requireNotAgent() (or require browser interaction for login) and will fail or be inappropriate when run by an agent.
