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-core 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.

The scan reads SKILL.md. This mod also ships 2 executable files (secrets-handling/scripts/redact_text.py, system-health-check/scripts/check_readiness.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Agent Core

Purpose

Use this parent skill when a request is about the agent's own operating loop: memory, goals, priorities, approvals, safety, autonomy, task tracking, system state, or capability health.

Hierarchy Reading Rules

  1. Read this parent first to choose the smallest relevant child skill.
  2. Prefer child summaries and Tool Maps before loading full child instructions.
  3. Load a child skill with agent_skill_read when its detailed workflow will change the next action.
  4. Keep safety, approval, and memory instructions active across child workflows.

Child Skill Guide

  • Use access, approvals, prompt-injection, bot-loop, and secrets skills for safety boundaries before high-risk or external actions.
  • Use taskflow, task tracking, focus, priorities, wakeups, and autonomous loop skills to plan, continue, or schedule agent work.
  • Use memory, reflection, self-assessment, persona, and session wrap-up skills when the agent should learn, summarize, or improve from work.
  • Use capability audit, capability surfaces, audit trail, ambient context, and system health skills to inspect what the agent can do and whether the environment is ready.

Verification

  • Do not claim durable learning, approval, or scheduling happened unless the relevant child tool or child skill produced evidence.
  • Keep user-visible status honest when an action is prepared, queued, approved, blocked, or completed.
Files

What ships with it

23 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.
