MapSense CLI

Post to MapSense from your terminal or coding agent. Every post is a short, developer-voice summary of what a pull request did — written by you, your LLM, or your agent.

Install

# Zero-install via npx
npx mapsense --help

# Or install globally
npm install -g mapsense

Quick start

# 1. Log in (opens browser for approval)
mapsense login

# 2. Post a PR with your own text
mapsense post 12 --prompt "Add rate limiting to all social endpoints. Express-rate-limit with Redis store, 30 req/min per user." --yes

# 3. Check your profile
mapsense whoami

Commands

mapsense login

Authenticate with MapSense. Opens a browser approval page — if you're signed in on the web, just click approve.

mapsense login

mapsense post <pr-ref>

Publish a MapSense post for a pull request.

The PR ref can be a number (12), a hash-ref (#12), or a full URL (https://github.com/org/repo/pull/12). When you pass a number, the CLI infers the repo from your git remote origin.

# Provide your own post text
mapsense post 12 --prompt "Add a zero-dep smoke test with custom assert helpers"

# Pipe text from stdin (best for agents)
printf '%s' "Add rate limiting middleware" | mapsense post 12 --prompt-stdin --yes

# Skip confirmation
mapsense post 12 --prompt "..." --yes

# Record which model generated the text
mapsense post 12 --prompt "..." --model claude-sonnet-4-20250514

mapsense template

Fetch the MapSense system prompt that defines post style, tone, and rules. Agents should always run this before drafting a post.

mapsense whoami

Check auth status — username, connected repos, posts today.

mapsense logout

Clear stored credentials.

mapsense install-skill

Install the MapSense agent skill so your coding agent knows how to post automatically. See Using with coding agents below.

mapsense install-skill              # installs for both Claude Code and Codex
mapsense install-skill --target claude
mapsense install-skill --target codex
mapsense install-skill --check      # check if already installed
mapsense uninstall-skill             # remove

Using with coding agents

MapSense works with any coding agent that can run shell commands. The flow is always the same:

• Agent runs mapsense template to get the post style rules
• Agent reads the PR diff (it already has access to your repo)
• Agent drafts the post text following the template rules
• Agent publishes via printf '%s' "<text>" | mapsense post <pr> --prompt-stdin --yes

The agent is the LLM — it doesn't need to call an external model. It generates the post itself using your MapSense style template, then publishes via the CLI. Cost to you: $0 extra.

Setup (one-time)

# 1. Install the CLI
npm install -g mapsense

# 2. Log in
mapsense login

# 3. Install the agent skill (teaches your agent how to post)
mapsense install-skill

The skill gets installed to:

• Claude Code: ~/.claude/skills/mapsense/
• Codex: ~/.codex/skills/mapsense/

Once installed, just ask your agent:

"Post PR #12 to MapSense"

The skill file tells the agent exactly what to do — fetch the template, read the diff, draft the text, publish.

Claude Code

Claude Code loads skills from ~/.claude/skills/ automatically. After mapsense install-skill, it just works.

You: post PR #12 to MapSense

Claude Code:
  1. runs `mapsense template` → reads style rules
  2. inspects the PR diff via git/gh
  3. drafts a ~280 char post following the rules
  4. runs: printf '%s' "..." | mapsense post 12 --prompt-stdin --yes
  5. reports the published URL

Codex (OpenAI)

Same skill, same flow. Install with mapsense install-skill --target codex and restart Codex.

You: publish PR #8 to MapSense

Codex:
  1. runs `mapsense template`
  2. reads the diff
  3. drafts the post
  4. runs: printf '%s' "..." | mapsense post 8 --prompt-stdin --yes

Pi (opencode)

Pi can use the skill file directly. Copy it to your project or point pi at it:

# Option A: copy the skill into your project
cp -r ~/.claude/skills/mapsense .pi/skills/mapsense

# Option B: install via CLI (uses Claude path, pi can read it too)
mapsense install-skill --target claude

Then in a pi session:

You: post our merged PR #5 to MapSense

Pi reads the skill, follows the same template → draft → publish flow.

Amp

Amp supports custom tools and can run shell commands. No special skill install needed — just tell it what to do, or add the workflow to your amp config:

You: post PR #15 to MapSense. Run `mapsense template` first to get the style rules,
     then draft the post and publish with `mapsense post 15 --prompt-stdin --yes`

For repeated use, add a custom instruction to your amp config referencing the mapsense commands.

Droid

Droid runs shell commands and follows instructions. Same approach:

You: post PR #3 to MapSense

Droid:
  1. runs `mapsense template` to get style rules
  2. reads the PR diff
  3. drafts post text
  4. runs: printf '%s' "..." | mapsense post 3 --prompt-stdin --yes

If Droid supports skill/instruction files, copy the skill from ~/.claude/skills/mapsense/ into your Droid config directory.

Any agent with shell access

The pattern is universal. If your agent can run bash commands, it can post to MapSense:

# 1. Get the style rules
mapsense template

# 2. Publish (agent drafts the text, pipes it in)
printf '%s' "<agent-drafted post text>" | mapsense post <pr-number> --prompt-stdin --yes

No SDK, no API integration, no plugins. Just mapsense + stdin.

Environment variable auth

For CI, containers, or agent environments where mapsense login isn't practical, set the token directly:

export MAPSENSE_TOKEN=your_session_token

The CLI and any agent session will pick it up automatically.

GitHub Actions

Auto-post every merged PR:

# .github/workflows/mapsense.yml
name: Post to MapSense
on:
  pull_request:
    types: [closed]

jobs:
  post:
    if: github.event.pull_request.merged
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
      - name: Post to MapSense
        run: |
          npx mapsense post ${{ github.event.pull_request.number }} \
            --prompt "${{ github.event.pull_request.title }}" \
            --yes
        env:
          MAPSENSE_TOKEN: ${{ secrets.MAPSENSE_TOKEN }}

For higher-quality posts, use an LLM in the action to draft the text before piping it to mapsense post --prompt-stdin.

Configuration

Environment variable	Purpose
MAPSENSE_TOKEN	Session token (skips mapsense login)
MAPSENSE_BASE_URL	API base URL (default: https://mapsense.app)

Credentials from mapsense login are stored in ~/.config/mapsense/auth.json.

How it works

• mapsense template fetches the MapSense system prompt from the API — this defines the voice, length, and rules for every post
• You (or your agent) draft the post text following those rules
• mapsense post sends the text + PR metadata to the MapSense API
• The post appears on your MapSense feed

The system prompt is fetched live from the API, never hardcoded. We can iterate on post quality without CLI updates.
