star-chamber

star-chamber is a skill for Claude Code from peteski22/agent-pragma. It costs 22 tokens per session (545 once invoked), scanned A, original, Apache-2.0.

A council that asks several AI systems to review code or answer design questions, then combines their feedback into recommendations.

In plain words
What is it for?
Use it for recent-change reviews and architecture questions, with optional provider selection, request time limits, or multi-round debate.
Why use it?
It reduces reliance on one reviewer when a design choice or complex code review needs different perspectives.

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

star-chamber 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 10d 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.

Star-Chamber: Multi-LLM Craftsmanship Council

This skill is for explicit /star-chamber invocations with live progress in the main conversation. It supports --debate for multi-round deliberation. For automatic invocation on architectural decisions, the star-chamber agent handles that separately.

Advisory skill that fans out code reviews and design questions to multiple LLM providers (Claude, OpenAI, Gemini, etc.) and aggregates their feedback into consensus recommendations.

Arguments

Flag Description Manual Only
--provider <name> LLM provider to use (repeatable, e.g., --provider openai --provider gemini). Defaults to all in config. No
--file <path> Specify file to review (repeatable). Defaults to recent git changes. No
--timeout <seconds> Timeout per provider request (overrides config timeout_seconds). No
--debate Enable debate mode: multiple rounds with summarization between rounds. Yes
--rounds N Number of debate rounds (default: 2, requires --debate). Yes

Manual-only flags are skill invocation parameters interpreted by Claude Code, NOT flags passed to the star-chamber CLI. Debate mode is orchestrated by Claude Code (see Debate Mode in the protocol).

Path Setup

The skill loader provides the base directory in the header: Base directory for this skill: <path>. Set the path variable used throughout the protocol:

STAR_CHAMBER_PATH="<base directory from header>"
# e.g., STAR_CHAMBER_PATH="$HOME/.claude/plugins/cache/pragma/skills/star-chamber"

Protocol

Read and follow the full protocol from $STAR_CHAMBER_PATH/PROTOCOL.md. It contains Steps 0-4: prerequisite checks, invocation mode detection (code review vs design question), review target identification, context gathering, CLI invocation, and result presentation. Debate mode is documented as a separate section.

Auto-Invocation

This skill is not auto-invoked (model-invocable: false). The star-chamber custom subagent handles auto-invocation based on its description. This skill is for explicit /star-chamber invocations only.

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.
