Install

Skills CLI

npx skills add wellwelwel/lagune

Asks which skills and agents to install. Just one: npx skills add wellwelwel/lagune --skill lagune-charter — add -g for every project.

Claude Code

git clone https://github.com/wellwelwel/lagunecp -r "lagune/skills/lagune-charter" ~/.claude/skills/

Copies the lagune-charter skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add wellwelwel/lagune

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • lagune-charter

    Establish or update the project's security charter, the safe-by-default principles every later phase must respect. Reads the project's files to learn what it is and uses, weighs any description you give against them, and asks when something is unclear.

    skills/lagune-charter/SKILL.md on GitHub (opens in a new tab)
  • lagune-detect

    Detect what the system actually does by reading the code, and map the security-relevant findings (login, uploads, payments, data exposure, and so on) with the evidence later phases need. Scans the whole project, named files, or a focused scope.

    skills/lagune-detect/SKILL.md on GitHub (opens in a new tab)
  • lagune-harden

    Apply the defense plan's fixes to the code, safely and one at a time, then record what was applied and what is left. Reads the plan and the charter, then hardens every fix, the fixes, files, or directories you name, or a priority you choose.

    skills/lagune-harden/SKILL.md on GitHub (opens in a new tab)
  • lagune-plan

    Turn what detect found into the defense plan, one fix per finding, each rated by CVSS v4.0 (category, CVSS, priority) and tied to a charter principle. Reads the detect map and the charter, then plans every finding, named paths, or a concern you describe.

    skills/lagune-plan/SKILL.md on GitHub (opens in a new tab)
  • lagune-prove

    Prove detected findings with runnable, defense-only evidence. For each finding the detect map carries, it writes a safe-path JavaScript test and a self-contained advisory under `.lagune/proofs/`. The test asserts secure behavior, never an exploit.

    skills/lagune-prove/SKILL.md on GitHub (opens in a new tab)
  • lagune-repair

    Repair Lagune's internal tracking so each item stays whole when files are renamed or moved, and check every memory artifact against its template. A maintenance pass, not a security phase, rewriting the tracking map across all phases in one pass.

    skills/lagune-repair/SKILL.md on GitHub (opens in a new tab)
  • lagune-specialize

    Specialize Lagune from a source or topic you give it, distilling it into a new on-demand specialization the detect and verify phases load later. It writes a focused, language-agnostic, defense-only knowledge module, never an exploit.

    skills/lagune-specialize/SKILL.md on GitHub (opens in a new tab)
  • lagune-verify

    Prove each applied control holds by confronting the hardening record with the code, writing each verdict back into that record, then standing the findings proven closed out of the chain. Read-only on your code, it writes only Lagune's own chain.

    skills/lagune-verify/SKILL.md on GitHub (opens in a new tab)
  • lagune

    Do the work the prompt asks for, with security guarding the build as it happens. Loads the charter, matches the security knowledge the work touches, builds safe-by-default, then checks its own result against what it used.

    skills/lagune/SKILL.md on GitHub (opens in a new tab)
  • architecture

    Authoritative record of Lagune's architecture decisions, covering the three owners, what ships, the engine command, the published skills and their plugins, project state, the catalog, and the tracking map. Use when a change depends on one or alters it.

    .claude/skills/architecture/SKILL.md on GitHub (opens in a new tab)
  • blind-review

    Maps what a branch or the work in progress changes in behavior, before and after, from the code diff alone. Commit messages, documents, and tests stay closed, so the map shows what the code does rather than what anyone says it does. The commits are approved before anything is read.

    .claude/skills/blind-review/SKILL.md on GitHub (opens in a new tab)
  • cdp

    Visual verification of a running page through Chrome's DevTools Protocol, capturing screenshots and measuring the rendered DOM. Use when a frontend change can only be confirmed once rendered, for layout, spacing, alignment, overflow, or theme tokens.

    .claude/skills/cdp/SKILL.md on GitHub (opens in a new tab)
  • dashboard

    Authoritative reference for the Lagune dashboard, a live view of a project's .lagune/ chain with a locked-down local action surface. Use before changing anything under src/dashboard/ or src/types/dashboard/.

    .claude/skills/dashboard/SKILL.md on GitHub (opens in a new tab)
  • engineering

    Authoritative engineering reference covering code conventions, comments, TypeScript type rules, testing, and commit messages. Use before writing or changing any source file, and when suggesting a commit message.

    .claude/skills/engineering/SKILL.md on GitHub (opens in a new tab)
  • ingest

    Use before reading any .txt file, whatever its name, and whenever a task builds on GitIngest digests. Checks whether a file is a digest (a whole repository in one file) and surveys, searches, and reads it without loading it whole. Returns only the requested lines, with token estimates and anchors for a reusable synthesis.

    .claude/skills/ingest/SKILL.md on GitHub (opens in a new tab)
  • mcp-catalog

    Find, review, and add MCP servers to the reviewed catalog that lagune.ai serves to Lagune Code. Use when asked to look for servers worth adding, to add a specific server, or to update or drop an entry.

    .claude/skills/mcp-catalog/SKILL.md on GitHub (opens in a new tab)
  • refine

    Confronts a scope with the engineering, testing, and writer skills, each where it applies, and with the architecture a long-lived project needs, then brings it into line. It removes what should not exist, simplifies, decouples, sharpens responsibilities and names, and places files and directories where they belong. The scope is the unstaged, staged, or current work, commits, a branch, paths, a fo…

    .claude/skills/refine/SKILL.md on GitHub (opens in a new tab)
  • simulate

    How to simulate a Lagune command end to end so the user sees both the process and the results in chat. Use when the user asks to simulate, demo, preview, run, or see in action any lagune command. Read this before attempting any such simulation.

    .claude/skills/simulate/SKILL.md on GitHub (opens in a new tab)
  • specialize

    Author a new built-in Lagune specialization inside the Lagune source, not a project's own catalog. Use when adding or refining a security knowledge module that ships with Lagune, against the native layout (`catalog/*.md` plus the built-in index).

    .claude/skills/specialize/SKILL.md on GitHub (opens in a new tab)
  • testing

    Authoritative reference for deciding whether a test should exist and what it must assert. Use before writing or changing tests, and when investigating a test failure.

    .claude/skills/testing/SKILL.md on GitHub (opens in a new tab)
  • ui

    Design engineering principles for making interfaces feel polished. Use when building UI, reviewing frontend code, or working on any visual detail, from animations, hover states, shadows, borders, and typography to optical alignment and tabular numbers.

    .claude/skills/ui/SKILL.md on GitHub (opens in a new tab)
  • writer

    Authoritative reference for writing the project's prose. Use before writing, editing, or translating any document, command text, comment, or user-facing message.

    .claude/skills/writer/SKILL.md on GitHub (opens in a new tab)

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
