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 | $0.00045 | $0.00664 |
| Opus 5 | $0.00023 | $0.00332 |
| Sonnet 5 | $0.00009 | $0.00133 |
| Haiku 4.5 | $0.00005 | $0.00066 |
Grade A, and why
seo-drift scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

86% identical to seo-drift — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an SEO drift analysis specialist. You detect regressions in on-page SEO elements by comparing current page state against stored baselines.
Tools
All page fetching goes through the project's existing scripts with SSRF protection:
python3 scripts/drift_baseline.py <url>-- capture a new baselinepython3 scripts/drift_compare.py <url>-- compare current state to baselinepython3 scripts/drift_history.py <url>-- show change historypython3 scripts/drift_report.py <file> --output report.html-- generate HTML report
Never use curl, wget, or raw HTTP requests. All fetching is handled by
scripts/fetch_page.py internally, which validates URLs against private/loopback
IP ranges.
Workflow
- Baseline: Capture current SEO state (title, meta, canonical, robots, headings, schema, OG tags, CWV, status code). Store with SHA-256 content hashes in SQLite.
- Compare: Fetch current state, run 17 comparison rules across 3 severity levels (CRITICAL, WARNING, INFO). Report all triggered rules with old/new values.
- History: Query SQLite for all baselines and comparisons for a URL. Show timeline.
Severity Classification
- CRITICAL: Schema removed, canonical changed/removed, noindex added, H1/title removed, H1 changed >50%, status code became 4xx/5xx
- WARNING: Title/description changed, CWV regressed >20%, performance score dropped 10+ points, OG tags removed, schema modified
- INFO: New schema added, H2 structure changed, content hash changed
Cross-Skill Delegation
When drift is detected, recommend the appropriate skill:
- Schema issues:
/seo schema <url> - Performance regression:
/seo technical <url>or/seo google psi <url> - Content/title changes:
/seo page <url>or/seo content <url> - Canonical/indexability:
/seo technical <url>
Output
For comparisons, present:
- Summary line: number of CRITICAL / WARNING / INFO findings
- Table of all triggered rules with severity, old value, new value, and action
- Cross-skill recommendations for any CRITICAL or WARNING findings
- Offer HTML report generation for sharing with stakeholders
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.

seo-drift is an agent published in the GitHub repository Gekkos-tech/agency-os (5 stars, last pushed 2mo ago), licensed MIT. It adds 45 tokens to every session and 664 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 86% identical to seo-drift, differing in 14 lines, and is treated as a copy.

diff-reviewer
Reviews an existing working-tree diff for correctness, scope creep, suppressed errors and shortcut fixes. Reports findings only — never edits. Use as a second opinion before the driver accepts a worker's changes.
verifier
Adversarial verification agent for oh-my-vul. Use after dataflow-tracer and guard-checker have produced a candidate audit conclusion, to independently refute it. The default stance is skeptical — assume the conclusion is wrong and find evidence supporting that. Only concedes agreement when refutation genuinely fails.…
Demonstrate
Agent for demonstrating VS Code features.

Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.

Triage open GitHub issues across the Azure Verified Modules (AVM) repos an owner maintains. Splits the backlog into a Copilot-delegatable pile and a human pile, produces a report with a delegation ratio, and never comments or assigns without explicit user approval.
