WIGTN Plugin v1: Claude Code

WIGTN Plugin v1 is the Claude Code plugin, and v0.1.16 landed on 4 August 2026. Two releases went out that day. v0.1.15 cut the plugin back to its contracts, and v0.1.16 added knowledge-wiki, a skill that writes down what a session established and puts a gate in front of anything leaving the machine.

The direction is the part worth noticing. This is the second time the plugin has been cut rather than extended, and the report is where that history is measured instead of asserted.

What changed since v0.1.14

v0.1.14 is where this page used to stop, so that is the version worth measuring against. Two releases have landed since, both on 4 August 2026.

• v0.1.15 cut the harness back to its contracts. The agent count went from 13 to 11.
• v0.1.16 added knowledge-wiki, the skill that writes down what a session established and gates what leaves the machine. The skill count went from 6 to 7.
• Across both: 50 files changed, 3,274 lines added and 3,608 removed. The release removes more than it adds, which is the point of it.
• Unchanged: the install id, the commands, the 20 design styles, and the licence.

Get it

Two lines, verbatim from the v0.1.16 README:

• /plugin marketplace add wigtn/wigtn-plugins
• /install wigtn-plugins

The install id is wigtn-plugins, not wigtn-coding. The plugin was renamed on 2 June 2026 and the old id stopped working then; namespaced subagent calls became wigtn-plugins:<agent> in the same change. The repository moved with it, from wigtn-plugins-with-claude-code to wigtn-plugins. GitHub still redirects the old address, so an old link lands fine, but a cloned remote is worth updating.

What shipped

Nothing here compiles. The plugin is Markdown agent definitions, command definitions, skills, one hooks file, and a shell script the quality gate writes into your own repository.

• knowledge-wiki, the v0.1.16 addition: a session's conclusions are written to a wiki, and four checks run before anything is published out of the machine it was written on.
• The package surface at v0.1.16, from the manifest and checked against the tree: 11 agents, 5 commands, 7 skills, 20 design styles. That is an inventory of what is in the box, not a claim about what comes out of it. The tech report is where that claim is examined, and declined.
• Apache 2.0, unchanged.
• Not included: any benchmark. No measurement of this plugin against a single-agent baseline has been published, at this version or any other. The one controlled result we have is on the Codex side, and it covers two tasks on one model.
• Also not included: a standalone runner. It works inside Claude Code and nowhere else.

Read the report

The workflow this release sits inside is in the WIGTN Coding tech report: the six stages, the three layers of shared memory, and what happened to the instruction surface over seven months, which is the thing this release is another step in. The release history, the agent definitions and the commit hook are in the repository. Both are linked at the top of this page.
