ai-detect

ai-detect is a skill for Claude Code from VKirill/claude-lane-stack. It costs 236 tokens per session (648 once invoked), scanned A, original, MIT.

A procedure for detecting and correcting signs that text may have been generated by AI, using a named linguistic analysis method. Its results are probabilistic, so they do not prove who wrote the text.

In plain words
What is it for?
Use it to run the listed detection modes on an original text and produce an analysis, or to correct the identified issues when the procedure calls for it.
Why use it?
It helps assess whether writing has patterns associated with generated text while avoiding an unsupported claim of authorship.

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.

Fable 5.1 $0.00236 $0.00648

Security

Grade A, and why

ai-detect 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 1mo 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

LinguaForensic AI Text Detector v3.9.4

Protocol

  1. Open the canonical original and apply it byte-identically — do not summarize, translate, or “improve” the skill text:
  2. Older versions in references/ (v3.8.6, v3.8.12, v3.8.5, v3.4) are historical only — use them only to reproduce an old report.
  3. Output is probabilistic. Never claim “proved authorship”.
  4. For pure editorial naturalness without detector optimization → use drmax-text-humanization (downstream of GIST).
  5. For replaceability (not style) → X4 /заменяемость / GIST 4.3.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

ai-detect is a skill published in the GitHub repository VKirill/claude-lane-stack (122 stars, last pushed today), licensed MIT. It adds 236 tokens to every session and 648 once invoked, about $0.0009 per session on Opus 5.5. 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 2026-09-05.
