updating-plugin-assets

updating-plugin-assets is a skill for Claude Code, Codex from infraspecdev/tesseract. It costs 54 tokens per session (1,783 once invoked), scanned A, original, MIT.

A maintenance workflow for add-on files such as skills, commands, agents, hooks, and evaluation tests. An evaluation is an executable check that confirms the add-on behaves as intended.

In plain words
What is it for?
Use it when editing plugin assets to identify the required checks, add evaluation coverage, and verify the change before it ships.
Why use it?
It ensures changes to these files include lasting tests and a record showing that the tests first failed and then passed.

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

updating-plugin-assets 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 5d 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.

Updating plugin assets

Overview

Every plugin-asset change in tesseract/ must ship with an executable eval that exercises the new or changed behavior. In-conversation GREEN dispatches are necessary but not sufficient — they don't survive into the repo and can't regression-test future changes. This skill is the procedural companion to the Eval coverage — MANDATORY policy in CLAUDE.md.

Authoritative reference: shield/evals/README.md.

REQUIRED SUB-SKILL when editing a SKILL.md: Use superpowers:writing-skills for skill-content quality (CSO, frontmatter, structure, pressure-test methodology). This skill and writing-skills are complementary, not alternatives — writing-skills covers how to write a good skill; this skill covers how to ship the change in this repo. Load both.

When to use

Trigger this skill whenever you are about to write or edit:

  • **/skills/**/SKILL.md
  • **/agents/*.md
  • **/commands/*.md
  • **/.mcp.json or MCP server prompts under */server/
  • **/hooks/* and **/scripts/* that hooks invoke
  • Skill-orchestrator wiring (the prompts a skill uses to dispatch subagents)
  • Anything under shield/evals/ (the eval system itself)

When NOT to use

  • Pure doc edits (README typo, comment rewording, link fix)
  • Renames with no behavior change
  • Dependency bumps with no prompt/behavior change

For these, state "no eval-shaped surface" in the PR body and proceed.

Doc-authoring skills — writing-style contract

If the asset you are adding or editing is a doc-authoring skill (it writes a doc to docs/shield/ — e.g. prd-docs, plan-docs, lld-docs, research, or any future equivalent), it MUST include an explicit step that applies shield:writing-style to its author-written prose before writing. Prose only — never rendered/marker-wrapped sections or JSON sidecars. This is part of the definition of done for such skills, alongside eval coverage.

Workflow

Before step 1: verify the asset actually exists at the path the user named and the section/symbol you intend to change is real. If the path or section name is wrong, surface the mismatch and ask — do not silently re-target. Following procedure on the wrong file is worse than not following procedure at all.

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.
