What it does when it runs

Deprecated alias. This skill was renamed to `deepline-scoring`. Use when a user or script still invokes `/niche-signal-discovery`: immediately load and follow the `deepline-scoring` skill instead. Triggers: ICP analysis, niche signals, won vs lost analysis, differential signals, signal discovery, ICP signal report, account scoring signals, lead scoring, first-party signals, buyer signals.

Automated analysis of the skill and the 1 file bundled beside it. A skill’s own description is written to be selected by an agent, so it describes the job and not the dependencies.

Keys and connectors you must supply: None found.
Hosts it reaches: code.deepline.com
Tool permissions it declares: No allowed-tools in the frontmatter. It does act, so it runs under whatever permissions your session already grants.
Actions present in the files: shell

Our read

Computed from the artifact. Nothing here has been run, so none of it is a claim about how well the skill works — only about what it is and what it needs.

CouplingReaches the web

Reaches a third-party host at runtime, but needs no key of its own.

It acts, and declares no `allowed-tools`, so it inherits whatever your session already permits.

git clone --depth 1 --filter=blob:none --sparse https://github.com/getaero-io/gtm-eng-skills.git /tmp/gtm-eng-skills
git -C /tmp/gtm-eng-skills sparse-checkout set "skills/niche-signal-discovery"

cp -R "/tmp/gtm-eng-skills/skills/niche-signal-discovery/." ~/.claude/skills/niche-signal-discovery/

Picked up without a restart. A project skill of the same name is shadowed by your personal one. For one repository only, swap ~/.claude/skills for .claude/skills. Claude Code docs ↗

Or take the whole library

This repo ships a .claude-plugin manifest, so Claude Code can install all 21 skills at once. Plugin skills are invoked as /<plugin>:<skill>, so they never collide with your own.

/plugin marketplace add getaero-io/gtm-eng-skills
/plugin

The folder is the same in every client that implements the format — 46 of them — so if yours is not above, only the destination changes.

Source on GitHub ↗

Reproduced in full from getaero-io/gtm-eng-skills/blob/ce24f7d2f73830ad3690ff2e6c57c375d818e6fc/skills/niche-signal-discovery/SKILL.md, which is licensed MIT (repository). 178 words, 4 headings.

niche-signal-discovery (renamed to deepline-scoring)

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

This skill was renamed. niche-signal-discovery is a temporary alias kept so existing prompts, scripts, and saved commands keep working. It will be removed.

What to do

Load the deepline-scoring skill and follow it for this request. Do not answer from this file; it contains no instructions of its own.

If the skill loader supports names, invoke deepline-scoring. Otherwise read the entrypoint directly, trying these roots in order and using the first that exists:

for candidate in \
  "$PWD/.skills/deepline-scoring" \
  "$HOME/.claude/skills/deepline-scoring" \
  "$HOME/.agents/skills/deepline-scoring"; do
  [ -d "$candidate" ] && { echo "$candidate/SKILL.md"; break; }
done

Then tell the user once, in a single line, that /niche-signal-discovery is now /deepline-scoring, and continue with the actual request.

Files bundled with it

These load only when the skill asks for them, so they cost nothing until it runs.
