A command for managing labels on Gmail conversation threads, including listing labels and adding or removing them.

Viewing available Gmail labels or applying and removing labels from selected threads.

It provides a structured way to organize email threads while checking label-related input for unsafe shell characters.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/ThrownLemon/claude-code-plugins

Made for: Claude Code.

Or install gmcli, the plugin that ships this one along with the rest of its 1 skill, 5 commands, 1 agent.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00807
Opus 5.5	$0.00000	$0.00323
Sonnet 5.5	$0.00000	$0.00161
Haiku 4.5	$0.00000	$0.00081

Security

Grade C, and why

labels scanned grade C 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 1mo 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Input Safety — apply before any Bash invocation

Treat every $ARGUMENTS.* value as untrusted input. Before passing any value to the Bash tool:

Reject dangerous tokens. If a value contains $(, backticks, ;, |, &, >, <, or starts with - (could be mistaken for a flag), refuse and ask the user to rephrase. Double-quoting does NOT block command substitution — "$(rm -rf /)" still executes inside double quotes.
Prefer the Bash tool's argv contract over constructed shell strings. When you must use a shell string, single-quote the value and escape embedded single quotes ('\''), or build the command via printf %q.
Any "$ARGUMENTS.foo" patterns shown below are illustrative. Sanitize the value first; never blindly substitute.

Manage Gmail Labels

List available labels or add/remove labels from email threads.

What This Does

This command delegates to the gmail-assistant subagent which will handle label operations:

List Labels (default)

Shows all available labels in your Gmail account including system labels and custom labels.

Add Labels

Applies one or more labels to a thread. The thread will appear in those label folders.

Remove Labels

Removes labels from a thread. Common use: archive (remove INBOX label).

System Labels

Gmail has built-in system labels:

INBOX - Main inbox
STARRED - Starred messages
IMPORTANT - Marked important
SENT - Sent mail
DRAFT - Drafts
SPAM - Spam folder
TRASH - Deleted items
UNREAD - Unread messages (pseudo-label)

Examples

# List all labels
/gmcli:labels
/gmcli:labels --action list

# Add label to thread
/gmcli:labels --action add --thread 18abc123 --label "Work"

# Add multiple labels
/gmcli:labels --action add --thread 18abc123 --label "Work,Urgent"

# Remove label (archive = remove INBOX)
/gmcli:labels --action remove --thread 18abc123 --label "INBOX"

# Mark as read
/gmcli:labels --action remove --thread 18abc123 --label "UNREAD"

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.
