hotline-add-contact

hotline-add-contact is a skill for Claude Code, Codex from jtsternberg/claude-plugins. It costs 20 tokens per session (521 once invoked), scanned A, original, MIT.

A workspace-registration tool that adds the current project folder to dirmap, a directory lookup system used to find workspaces by short names. It can check whether the chosen name is already registered.

In plain words
What is it for?
Assigning a short alias such as “frontend” or “blog” to a workspace so hotline-dial can reach it.
Why use it?
It lets another tool locate this workspace without requiring its full filesystem path. It also detects when a name already points somewhere else before changing the mapping.

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

hotline-add-contact scanned grade A with 0 findings 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 8d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Hotline: Add Contact

Register a workspace in dirmap so it can be found by hotline-dial during workspace resolution.

Arguments

  • $1 (slug): The short name/alias for this workspace (e.g., blog, coaching, frontend). If not provided, ask the user.
  • $2 (path): The workspace path to register. Defaults to the current working directory if not provided.

Steps

1. Determine Slug and Path

SLUG="$1 or ask the user"
TARGET_PATH="$2 or $(pwd)"

If no slug was provided, ask the user:

What slug should I register this workspace under? (e.g., "blog", "coaching", "frontend")

Resolve the path to its canonical form:

TARGET_PATH=$(realpath "$TARGET_PATH")

2. Check for Existing Entry

Before adding, check if this slug already exists:

dirmap get "$SLUG" 2>/dev/null || dirmap-fallback.sh get "$SLUG" 2>/dev/null

If it exists and points to a different path, confirm with the user:

"$SLUG" is already registered at /existing/path. Overwrite with $TARGET_PATH?

3. Register the Workspace

if command -v dirmap >/dev/null 2>&1; then
  dirmap add "$SLUG" "$TARGET_PATH"
elif [[ ! -f "$HOME/.dirmap.json" ]]; then
  jq -n --arg slug "$SLUG" --arg path "$TARGET_PATH" \
    '{($slug): $path}' > "$HOME/.dirmap.json"
else
  jq --arg slug "$SLUG" --arg path "$TARGET_PATH" \
    '. + {($slug): $path}' "$HOME/.dirmap.json" > "$HOME/.dirmap.json.tmp" \
    && mv "$HOME/.dirmap.json.tmp" "$HOME/.dirmap.json"
fi

4. Confirm

Registered $SLUG$TARGET_PATH. Other agents can now find this workspace with hotline-dial.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
