Irrlicht: Skill for Claude Code

.claude/skills/ir:refresh-aliases/SKILL.md

ir:refresh-aliases is a skill for Claude Code from ingo-eichhorst/Irrlicht. It costs 97 tokens per session (1,450 once invoked), scanned A, original, MIT.

A maintenance tool for comparing a coding project's model-name aliases with the upstream list it was copied from. An alias is an alternate name that lets software recognize a model.

In plain words
What is it for?
Use it to review alias differences, update the Go alias map, run tests, and prepare or include the changes in a release.
Why use it?
It helps identify new or changed model names before they cause incorrect cost or model handling.

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

ir:refresh-aliases scanned grade A with 1 finding 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 9d 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.

Refresh Model Aliases from Codeburn

Irrlicht's core/pkg/capacity/aliases.go is a hand-translated port of codeburn's BUILTIN_ALIASES map. New frontends (Cursor releases, OMP variants, Antigravity Gemini models, etc.) appear upstream first; this skill keeps our map in sync.

Modes

This skill runs in two modes — the workflow below covers both; only the apply step (Step 7) differs.

  • Standalone (default — invoked as /ir:refresh-aliases or "refresh aliases"): produce a diff report, edit aliases.go, run tests, and open a PR. Maintainer reviews the PR before it lands on main.
  • Release-inline (invoked from /ir:release Step 1.5): produce the same diff, but edit aliases.go directly on the active release branch — no separate PR. The release commit ships the alias updates alongside the version bump. Fail-soft: if the fetch errors out (offline, upstream 5xx), continue the release with the existing map.

When to run (standalone)

  • Quarterly cadence (no schedule — maintainer triggers).
  • On demand whenever a session shows EstimatedCostUSD: 0 for a model the maintainer recognizes as a real provider (likely a new alias upstream).
  • Before cutting a release, if /ir:release's Step 1.5 wasn't run for some reason.

Workflow

1. Fetch upstream

curl -fsSL https://raw.githubusercontent.com/getagentseal/codeburn/main/src/models.ts > /tmp/codeburn-models.ts

If the fetch fails, stop and report the error — don't proceed with a stale copy.

2. Extract upstream BUILTIN_ALIASES

awk '/^const BUILTIN_ALIASES/,/^}$/' /tmp/codeburn-models.ts

The block is a single TypeScript object literal: 'key': 'value', per line, with grouping comments. Parse into an alias → canonical map. Ignore comment lines.

3. Load current Irrlicht map

Read core/pkg/capacity/aliases.go and extract entries from var modelAliases. Each line has the form:

"key": "value",

Strip whitespace, comments, and the surrounding map[string]string{…} boilerplate.

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.
