deepline-pre-research

deepline-pre-research is a skill for Claude Code, Codex from getaero-io/gtm-eng-skills. It costs 135 tokens per session (6,452 once invoked), scanned A, original, MIT.

A planning skill for researching public, private, customer-relationship, workflow, social, and web data sources before a Deepline research or enrichment job. Deepline is a go-to-market data and workflow tool.

In plain words
What is it for?
Use it to compare data providers, identify useful sources, plan enrichment research, and recommend a source plan.
Why use it?
It helps determine which sources cover the needed information and estimates the credit cost before the workflow is built or run.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deepline-pre-research scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/evaluate_examples.py, scripts/evaluate_public_private_corpus.py, scripts/query_design.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 466 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deepline Pre-Research

Quick Start

npm install -g deepline
# Fallback for secure sandboxes: mkdir -p "$HOME/.local" && npm config set prefix "$HOME/.local" && export PATH="$HOME/.local/bin:$PATH" && npm install -g deepline --registry https://code.deepline.com/api/v2/npm/
deepline auth register --wait auto
deepline auth wait --timeout 120 # completes Cowork/browser approval; no-op if already connected
deepline auth status
deepline -h

CLI resolution

Run deepline when it is available. If the shell reports that command is missing, use <workspace-root>/.deepline/runtime/bin/deepline (or the npm-created .cmd shim on Windows). If neither exists, follow https://code.deepline.com/INSTALL.md to set up Deepline.

Before the first Deepline fanout in a task, run deepline preflight --json as one standalone command and wait for it to finish. Never submit preflight beside another Deepline command. After it succeeds, prefix every Deepline command that may run concurrently with DEEPLINE_SKIP_SELF_UPDATE=1; serial commands may stay bare.

Find the highest-signal GTM data sources, public evidence, and market language for a research or enrichment job before building the pipeline. This is a standalone Deepline skill that should behave like last30days with a GTM data lens: broad source coverage, recency, community signals, citations, source stats, and a grounded "What I learned" synthesis. In Deepline, the report first explains what the research found; only after that does it translate the findings into Deepline tool contracts, private/proprietary joins, and Deepline-facing cost.

Non-Negotiables

  • Use Deepline's live tool catalog before naming provider actions. Do not rely on memory.
  • Run live web search. Do not answer public-source discovery from model memory. Every run MUST execute real searches (serper/exa, or the equivalent web-search tool) during the public-source fanout. If a run names public datasets without having searched for them this session, it has failed the fanout — no exceptions for "obvious" verticals. Naming a source family from memory is a draft, not a finding; the finding is the exact artifact the search returns. (Eval evidence: runs that skipped web search lost or tied on exactly the prompts where a competitor searched and surfaced concrete artifacts.)
  • Resolve every materializable dataset to its exact artifact, not its family. For each public dataset/registry you recommend, the fanout must return and record: (1) the exact file/endpoint name (e.g. IA_FIRM_SEC_Feed_YYYY_MM_DD.xml.gz, not "the ADV bulk feed"); (2) the canonical download/API URL; (3) any mirror (e.g. data.gov catalog copy) that is easier to pull; (4) an existing open-source parser or GitHub repo that already structures it, when one exists (search "<dataset> parser github"); (5) the government statistical registry for the vertical when one exists (BLS QCEW + NAICS codes, Census County Business Patterns, etc.) for free establishment counts and sizing. "Source family named" is not done. "Exact file + URL + mirror + parser + NAICS code recorded" is done. See the Artifact Resolution Gate (§4.55).
  • Public-source discovery comes before provider routing. First find the best public registries, datasets, communities, discussions, reviews, directories, papers, repos, and source leads. Then use Deepline routes to materialize, validate, enrich, and activate them.
  • Quote only customer-visible Deepline credits/USD. Never expose provider spend.
  • Do not run paid or cost-unknown full-scope work without approval.
  • Treat private data sources as first-class: CRM, warehouse, workflow runs, product analytics, support/calls, sheets, and customer-owned datasets.
  • Treat custom language as a first-class workflow: buyer words, objections, category language, competitor framing, community slang, sales-call phrasing, and support-ticket pain belong in the source plan.
  • Use tiny probes to learn coverage. Scale only after observed coverage, cost basis, and evidence quality are legible.
  • If the user asks for ScrapeCreators, X.com, Reddit comments, TikTok, Instagram, YouTube transcripts, Bluesky, Truth Social, HN, or Polymarket, include a current support/gap assessment instead of pretending every source is native.
  • Do not depend on /last30days at runtime. Reference it only as a design benchmark for source breadth and synthesis discipline.
  • Public registries and niche datasets that do not have native Deepline tools are still valid sources through generic web/search/extraction routes. For example, the NPI registry for healthcare provider taxonomy can be discovered and pulled through generic web/API search and extraction even when no native npi tool exists. Classify this as available through generic route, not as an unusable gap.
  • Every recommended source must be classified as native, available through generic route, private connector, or missing provider to add.

deepline-pre-research is a skill published in the GitHub repository getaero-io/gtm-eng-skills (58 stars, last pushed yesterday), licensed MIT. It adds 135 tokens to every session and 6,452 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
