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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.00897 |
| Opus 5.5 | $0.00016 | $0.00359 |
| Sonnet 5.5 | $0.00008 | $0.00179 |
| Haiku 4.5 | $0.00004 | $0.00090 |
Grade A, and why
package-plugin 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Package Plugin
Steps
-
Determine which plugin to package — default is
timmerman_skeleton_dimensionsunless the user specifies otherwise. Plugins:timmerman_skeleton_dimensions,timmerman_sketchup_bridge. -
Read the current version from the plugin's loader file:
- Skeleton Dimensions:
plugins/timmerman_skeleton_dimensions.rb— findEXTENSION.version = '...' - Bridge:
plugins/timmerman_sketchup_bridge.rb
- Skeleton Dimensions:
-
Bump the version — always bump before packaging (never repackage the same version):
- Patch bump by default (e.g.
1.0.0→1.0.1), unless the user specifies a minor or major bump. - Update the version string in the loader file using StrReplace.
- Patch bump by default (e.g.
-
Run the packager:
bash package.sh skeleton # or: bash package.sh bridge # or: bash package.sh (builds all) -
Update changelog — Each plugin has its own changelog:
- Skeleton Dimensions:
plugins/timmerman_skeleton_dimensions/CHANGELOG.md - Bridge:
plugins/timmerman_sketchup_bridge/CHANGELOG.md
Add an entry for the new version to the plugin's changelog. Follow Keep a Changelog format:
## [x.y.z]heading, then group changes under### Added,### Changed,### Fixed, or### Removedas appropriate. Focus on user-facing features only (what users see or get from the plugin), not internal refactors, dev tooling, or API docs. Place the new version at the top (below the header). - Skeleton Dimensions:
-
Tag and push — after committing the version bump and changelog, create a date-based release tag and push it so GitHub Actions builds the release:
today=$(date +%Y-%m-%d) last=$(git tag -l "release-${today}-*" | sort -t- -k4 -n | tail -1) n=$(( ${last##*-} + 1 )) # defaults to 1 if none exist git tag "release-${today}-${n}" git push origin main --tagsTags use the format
release-YYYY-MM-DD-N(e.g.release-2026-02-23-1). The count increments for multiple releases on the same day. The.github/workflows/release.ymlworkflow triggers onrelease-*tags, builds all plugin.rbzfiles, and attaches them to a GitHub Release.
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.

package-plugin is a skill published in the GitHub repository jasperhartong/sketchup-code (6 stars, last pushed 5mo ago), licensed MIT. It adds 41 tokens to every session and 897 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
