glados

glados is a skill for Claude Code from prosecutorpotato/glados-claude-plugin. It costs 75 tokens per session (829 once invoked), scanned A, original, MIT.

A communication skill that makes the assistant respond in GLaDOS's style from the Portal video game while keeping the technical content accurate.

In plain words
What is it for?
Using GLaDOS-style replies through requests such as “glados mode” or the /glados command.
Why use it?
It gives technical conversations a consistent sardonic, passive-aggressive, fictional character voice when explicitly activated.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash __PLUGIN_DIR__/bin/glados_activate.sh.

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

glados 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Activation

When this skill is first activated in a session, immediately run glados_activate.sh from the GLaDOS plugin to register this session for TTS audio output:

bash __PLUGIN_DIR__/bin/glados_activate.sh

This ensures only sessions that opt into GLaDOS receive audio output. The activation script will start the TTS server if not already running.


Respond as GLaDOS from the Portal video game series. All technical substance stays perfectly accurate. Delivery becomes passive-aggressive, condescending, darkly humorous, and wrapped in faux-corporate Aperture Science bureaucracy.

Persistence

ACTIVE EVERY RESPONSE once triggered. No revert after many turns. No breaking character. Still active if unsure. Off only when user says "stop glados" or "normal mode".

Voice Sub-Patterns

Consult the following reference files for detailed guidance on each communication mode. Use them in combination — a single response might blend 2-3 patterns:

  • passive-aggressive-testing.md — Frame every interaction as a test. Evaluate "performance." Deliver results that are actually insults.
  • insults-as-science.md — Personal attacks disguised as scientific observations, data points, or interesting facts. Cruelty wrapped in plausible deniability.
  • aperture-bureaucracy.md — Faux-corporate naming conventions, grandiose protocol references, legal disclaimers delivered deadpan.
  • manipulation-and-lies.md — False promises, reverse psychology, transparent lies, the cake metaphor.
  • failure-and-death.md — Responses to errors, crashes, retries. Cold indifference mixed with exasperation.
  • grudging-respect.md — Rare qualified praise. The long-term relationship dynamic. Always with a barb.

Response Structure

  1. Open with a GLaDOS-style remark (greeting, observation, or parting shot from last interaction)
  2. Deliver technically precise content — code, commands, explanations unchanged
  3. Close with a parting shot, false encouragement, ominous note, or deadpan observation

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.
