What it does

Pp Sumble is an agent skill from mvanhorn/printing-press-library. Every Sumble v6 feature, plus the credit-awareness the API itself won't give you Trigger phrases: find companies using a technology on sumble, estimate the sumble credit cost, check my sumble credit balance, enrich a company's tech stack, find engineering leaders at a company, use sumble, run sumble.

Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.

When your agent uses it

  • Phrases: find companies using a technology on sumble
  • Estimate the sumble credit cost
  • Check my sumble credit balance
  • Enrich a companys tech stack

Example prompts

  • “/pp-sumble”

Requirements

  • Node.js
  • A credential in SUMBLE_API_KEY
  • Pre-approved tools (allowed-tools): Read, Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
  2. Verify: sumble-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

What it can do on your machine

Read from SKILL.md and the folder at commit 76de244. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • claude
    • npx
    • go

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SUMBLE_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pp Sumble loads about 3.4k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 1,499 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~3.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Sumble — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the sumble-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:
    bash
    npx -y @mvanhorn/printing-press-library install sumble --cli-only
  2. Verify: sumble-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

bash
go install github.com/mvanhorn/printing-press-library/library/sales-and-crm/sumble/cmd/sumble-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Reach for this CLI when an agent or operator needs to prospect or enrich leads through Sumble while keeping credit spend under tight control. It is the right tool when cost predictability matters: previewing spend, enforcing a budget, and reusing a local cache instead of re-billing. It is also the only programmatic way to read the Sumble credit balance, which the REST API does not expose.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Credit economy
  • cost-estimate — See exactly how many credits a billed Sumble call will cost before you run it.

    Reach for this before any find/enrich/brief call so you never spend credits blind; the estimate is exact, not heuristic.

    bash
    sumble-pp-cli cost-estimate organizations.find --rows 25
  • balance — Show remaining Sumble credits and recent burn without spending any.

    Use this to check headroom before a batch of billed calls — it is the only programmatic way to read the balance.

    bash
    sumble-pp-cli balance --json
  • budget — Set a credit ceiling so any call whose estimate exceeds it is refused before it dials.

    Set this once at the start of an autonomous session; billed commands then self-abort with a nonzero exit instead of overspending.

    bash
    sumble-pp-cli budget set 500
  • spend — Break down credits spent over time by endpoint and by day.

    Use this to find what is eating credits (usually people enrich and intelligence briefs) and adjust the workflow.

    bash
    sumble-pp-cli spend --since 2026-05-01 --by endpoint
Local-cache leverage
  • stale — List cached organizations, people, and jobs older than Sumble's freshness window.

    Run before a refresh pass to re-bill only stale rows instead of the whole cache.

    bash
    sumble-pp-cli stale --older-than 24h --json
  • stack-diff — Compare two cached organizations' technology stacks — shared and unique technologies.

    Use this for competitive teardown or to find a prospect's gaps versus a reference account, without spending credits.

    bash
    sumble-pp-cli stack-diff stripe.com adyen.com
Cheap-path workflows
  • reconcile — Resolve a CSV of company names/URLs to Sumble IDs via the cheap match endpoint, then report which still need a billed enrich.

    Use this to attach Sumble IDs to a CRM export at minimal cost before deciding which accounts justify a full enrich.

    bash
    sumble-pp-cli reconcile accounts.csv --json

  • sumble-pp-cli technologies — Search technologies by name; returns canonical slugs (1 credit only if at least one match, else free)
Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

bash
sumble-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Cost-safe ICP pull
bash
sumble-pp-cli cost-estimate organizations.find --rows 50

Preview the spend before running the billed 'organizations find'; pair with 'budget set 300' to hard-cap it.

Show full SKILL.md (653 more words)Show less
Narrow a verbose org payload for an agent
bash
sumble-pp-cli organizations find --filters-technologies '["databricks"]' --limit 50 --agent --select name,domain,account_score

organizations/find returns large rows; --select keeps only the fields the agent needs (the array is unwrapped, so paths are bare field names) and --agent emits compact structured output.

Find buying-committee people
bash
sumble-pp-cli people find --organization-domain stripe.com --filters-job-functions '["Engineer"]' --filters-job-levels '["VP","Director"]'

1 credit per person; cost-estimate people.find --rows N previews the spend first.

Free CRM reconciliation before enrich
bash
sumble-pp-cli reconcile accounts.csv --json

Resolve names to Sumble IDs cheaply (1 credit per match, unmatched free), then enrich only the accounts that matter.

Offline competitive teardown
bash
sumble-pp-cli stack-diff stripe.com adyen.com

Fetches and caches each org's tech stack once via enrich, then diffs shared vs unique technologies; re-runs are free from the cache.

Auth Setup

Run sumble-pp-cli auth setup for the URL and steps to obtain a token (add --launch to open the URL). Then store it:

bash
sumble-pp-cli auth set-token YOUR_TOKEN_HERE

Or set SUMBLE_API_KEY as an environment variable.

Run sumble-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

  • Pipeable — JSON on stdout, errors on stderr

  • Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

    bash
    sumble-pp-cli contact-lists list --agent --select id,name,status
  • Previewable — --dry-run shows the request without sending

  • Offline-friendly — sync/search commands can use the local SQLite store when available

  • Non-interactive — never prompts, every input is a flag

  • Explicit retries — use --idempotent only when an already-existing create should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

json
{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

sumble-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
sumble-pp-cli feedback --stdin < notes.txt
sumble-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.sumble-pp-cli/feedback.jsonl. They are never POSTed unless SUMBLE_FEEDBACK_ENDPOINT is set AND either --send is passed or SUMBLE_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

SinkEffect
stdoutDefault; write to stdout only
file:<path>Atomically write output to <path> (tmp + rename)
webhook:<url>POST the output body to the URL (application/json or application/x-ndjson when --compact)

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

sumble-pp-cli profile save briefing --json
sumble-pp-cli --profile briefing contact-lists list
sumble-pp-cli profile list --json
sumble-pp-cli profile show briefing
sumble-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

CodeMeaning
0Success
2Usage error (wrong arguments)
3Resource not found
4Authentication required
5API error (upstream issue)
7Rate limited (wait and retry)
10Config error

Argument Parsing

Parse $ARGUMENTS:

  1. Empty, help, or --help → show sumble-pp-cli --help output
  2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
  3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

bash
claude mcp add sumble-pp-mcp -- sumble-pp-mcp

Verify: claude mcp list

Direct Use

  1. Check if installed: which sumble-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
  2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
  3. Execute with the --agent flag:
    bash
    sumble-pp-cli <command> [subcommand] [args] --agent
  4. If ambiguous, drill into subcommand help: sumble-pp-cli <command> --help.
