advisor

advisor is a skill for Claude Code, Codex from volomydyr/design-engineer-plugin. It costs 66 tokens per session (1,628 once invoked), scanned A, original, MIT.

A review checkpoint that asks a higher-capability helper agent for a short plan or course correction during coding work.

In plain words
What is it for?
Use it to check your direction, challenge assumptions, and review whether the planned work is complete.
Why use it?
It provides another perspective before major work, when you are stuck, or before calling a task finished.

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

advisor 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 4d 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.

Advisor Skill

This skill is the plugin-native implementation of Anthropic's advisor strategy. The literal advisor_20260301 server tool is an Anthropic API beta; Claude Code plugins don't control request shape, so we ship the strategy via a dedicated Opus 4.7 sub-agent that other skills consult at known checkpoints.

What it is

From the docs (verbatim):

"The advisor tool lets a faster, lower-cost executor model consult a higher-intelligence advisor model mid-generation for strategic guidance. The advisor reads the full conversation, produces a plan or course correction (typically 400 to 700 text tokens, 1,400 to 1,800 tokens total including thinking), and the executor continues with the task."

In our plugin, the calling skill briefs the advisor agent (Opus 4.7 xhigh) with the relevant context, the agent returns a short numbered plan, the caller applies or reconciles.

When to call advisor

From the docs' suggested coding-task system prompt (verbatim):

"Call advisor BEFORE substantive work – before writing, before committing to an interpretation, before building on an assumption. If the task requires orientation first (finding files, fetching a source, seeing what's there), do that, then call advisor. Orientation is not substantive work. Writing, editing, and declaring an answer are.

Also call advisor:

  • When you believe the task is complete. BEFORE this call, make your deliverable durable: write the file, save the result, commit the change. The advisor call takes time; if the session ends during it, a durable result persists and an unwritten one doesn't.
  • When stuck – errors recurring, approach not converging, results that don't fit.
  • When considering a change of approach.

On tasks longer than a few steps, call advisor at least once before committing to an approach and once before declaring done."

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.
