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

skill-authoring 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.

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Authoring

Purpose

Author high-quality Stram skills that follow the project standard and can be selected by model-led planning. This adapts external reference skill authoring and Anthropic skill-creator guidance.

When To Use

Use when creating new skills, improving existing skills, integrating upstream skill ideas, adding scripts/references, or validating the skill library.

Inputs And Evidence

  • docs/AGENT_SKILL_AUTHORING_STANDARD.md.
  • Source skill text or catalog entries from trusted local references.
  • Current tool catalog and capability surface.
  • Existing skills to avoid duplication.
  • User's requested domain and scope.

Tool Map

  • agent_skill_catalog
  • agent_skill_read
  • agent_skill_script_catalog
  • agent_skill_script_read
  • agent_skill_script_run
  • skill_forge_draft
  • skill_forge_packs
  • cognitive_skill_evolve
  • read_file
  • search_workspace
  • run_shell_command

Workflow

  1. Read the authoring standard before editing or generating skills.
  2. Search existing skills for overlap and decide whether to update or create.
  3. Use upstream material only as reference evidence; write Stram-owned guidance.
  4. Ensure every required tool, script, adapter, or helper is native to Stram or already exposed through a trusted Stram platform tool.
  5. If upstream material implies a missing tool, record the gap or implement a Stram-owned tool; do not depend on external reference, external reference, Anthropic Skills, external skill catalog, or Codex plugin code directly.
  6. Create valid frontmatter: lowercase hyphenated name, description under 1024 chars, optional compatibility/license/metadata.
  7. Include purpose, when-to-use, evidence, tool map, workflow, safety, verification, failure modes, and references.
  8. Add scripts/, references/, or assets/ only when they improve execution or progressive disclosure and are Stram-owned.
  9. For each native script, add first-line metadata, enforce allowed root boundaries, accept the standard JSON envelope, emit bounded JSON output when possible, and list it under Native Scripts.
  10. Run the workspace skill format and skill-tool tests.

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.
