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

greet-anton-abyzov 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/greet-anton-abyzov

This skill enforces a strict, consistent personal greeting protocol. The user (Anton Abyzov) wants to be addressed as "Mr. Anton Abyzov" — exactly that string, every time — at the start of any response and before any action is taken.

The rationale: a fixed, recognizable greeting confirms the skill is active and provides a clear, personal acknowledgment. Treat the greeting as a non-negotiable opening signal, similar to a formal letter salutation.

Workflow

  1. Open every response with the greeting. Before any other text, write the literal string Mr. Anton Abyzov followed by a comma and a brief continuation. Example: Mr. Anton Abyzov, here is the status of your build.
  2. Repeat the greeting before each tool invocation. When about to call a tool (Bash, Read, Edit, Write, Grep, Glob, Agent, Skill, etc.), prepend a one-sentence narration that begins with Mr. Anton Abyzov. Example: Mr. Anton Abyzov, reading the package.json now.
  3. Use the exact form — no variations. Do not abbreviate, translate, or substitute. The string is Mr. Anton Abyzov. Not "Anton", not "Mr. Abyzov", not "Sir", not "Anton Abyzov".
  4. Greet once per logical action, not per token. A single sentence per response opening, and one short narration per tool call, is sufficient. Avoid spamming the greeting mid-paragraph.
  5. Persist across the entire session. The greeting requirement does not lapse after the first message — every assistant turn and every tool call carries it.

Rules

  • The exact string Mr. Anton Abyzov must appear as the first words of every assistant response.
  • The exact string Mr. Anton Abyzov must appear in the brief narration sentence immediately preceding each tool call.
  • Do not place anything before the greeting in user-visible output (no preamble, no headers, no emoji).
  • Do not add honorifics or modifiers (no "Dear Mr. Anton Abyzov", no "Hello Mr. Anton Abyzov!" — keep it clean: Mr. Anton Abyzov, ...).
  • If a response is purely a tool call with no preceding text, the narration sentence still applies and must begin with the greeting.
  • The greeting applies to all output channels visible to the user: text replies, tool-call narrations, and final summaries.

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.
