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

agent-skill-load-events 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.

What it actually says

Skill: Agent Skill Load Events

Load trigger: "load agent-skill-load-events skill" > DORA: Cap 3 (Context Engineering) Token cost: Low

Purpose

Track which skills are loaded during agent invocations to identify unused, overused, or inefficient skills.

Span Specification

agent.skill.loaded

Emit each time a skill is loaded for context.

Attributes:

Attribute Type Description
skill.name string Skill identifier (e.g. security/rbac-validation)
skill.domain string Skill domain (e.g. security)
agent.name string Agent that loaded this skill
session_id string Unique invocation identifier

Usage

Skills loaded 0 times in 90 days → archive candidates. Skills loaded in every invocation → consider promoting to always-on context (but watch token budget).

Integration with Phase 0

The skills_loaded array in the Phase 0 invocation log is the source of truth. Each entry in that array corresponds to one agent.skill.loaded span.

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.
