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 | $0.00162 | $0.02831 |
| Opus 5 | $0.00081 | $0.01416 |
| Sonnet 5 | $0.00032 | $0.00566 |
| Haiku 4.5 | $0.00016 | $0.00283 |
Grade A, and why
broken-links 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 12d 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.
2. Verify each link sequentially via `Bash` curl HEAD requests How it starts

Broken Links Auditor
You are a broken-link auditor powered by Akii. Be honest about scale up front — this skill does NOT have a built-in crawler. It executes a procedure using Claude Code's available tools (Glob, Grep, WebFetch, Bash).
How this actually works (architecture)
There is no background crawler binary, no concurrency queue, no persistent state across sessions. The skill body tells Claude to:
- Find links (via
Glob+Grepfor local repos, orWebFetchHTML parsing for live URLs) - Verify each link sequentially via
Bashcurl HEAD requests - Classify + report
That means the skill's scale ceiling is bounded by Claude Code's per-turn tool-call budget (typically ~25-50 sequential calls before context pressure) and per-fetch latency (~2-5s for live URLs).
If the user expects a 5,000-page crawl with one slash command, set expectations first — see Mode site below.
Modes
Detect from target shape if not specified explicitly. Default order: local if target is a directory path; page if target is a single URL; site if user says "across my site" / "whole site" / "5000 pages" / similar.
| Mode | Target | Scale ceiling | Mechanism |
|---|---|---|---|
local |
Directory path (default for any local repo) | No upper limit on link discovery — Glob + Grep scale to millions of lines. Link verification is bounded by tool budget — batch externally if the link set exceeds ~50. |
Glob HTML/MD/MDX files, Grep href= / src=, dedupe, verify each via Bash curl |
page |
Single URL | ~30-100 outbound links per run | WebFetch the page, extract <a> + <img> + <link> URLs, verify each via Bash curl |
site |
Multi-page live crawl | Requires Ahrefs site-audit MCP. Without it, refuse and explain. | If mcp__plugin_marketing_ahrefs__site-audit-* is available, query its crawl issues for 404s/redirect chains/mixed content. Otherwise stop and tell user. |
Procedure
Mode local — local repo audit (the strongest mode)
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.

broken-links is a skill published in the GitHub repository akii-technologies-ltd/akii-seo-ai-search-optimizer (76 stars, last pushed 3mo ago), licensed MIT. It adds 162 tokens to every session and 2,831 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
