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.

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 | $0.00059 | $0.00430 |
| Opus 5 | $0.00030 | $0.00215 |
| Sonnet 5 | $0.00012 | $0.00086 |
| Haiku 4.5 | $0.00006 | $0.00043 |
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 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
/advisor — Second-Opinion Pass
Port of Claude Code's /advisor. Important limitation: Claude Code's native
/advisor actually routes the question to a second model for a genuinely
independent perspective. A skill running in the same agent/session can't do
that — it can only simulate a critical second pass within the same context.
Be upfront about that difference; frame the output as "a skeptical re-read,"
not "an independent second opinion."
Arguments
/advisor— critique the current plan/approach before proceeding/advisor <specific decision>— critique one specific choice rather than the whole plan
Steps
-
Restate the current plan or decision as it actually stands, not an idealized version of it.
-
Actively look for problems, from a skeptical stance rather than a supportive one:
- What assumption is this plan resting on that hasn't been verified?
- What's the failure mode if that assumption is wrong?
- Is there a simpler approach that was skipped over?
- What would this look like in 6 months — is it something that'll need rework soon?
-
Weigh, don't just list. Not every concern raised is equally important — say which ones are blocking versus worth noting versus minor.
-
Give a clear recommendation: proceed as-is, proceed with adjustments (name them), or stop and reconsider — don't just present pros/cons and leave it unresolved.
Notes
The value of this skill is in genuinely arguing against the current approach, not in politely rubber-stamping it. If the plan really is solid, say so plainly after actually trying to find holes — don't manufacture concerns to seem thorough.
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.

advisor is a skill published in the GitHub repository airvalona/antigravity-like-claude-code (2 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 430 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
