 ## Capabilities
 
 1. **Gather inputs** per `injury-params.schema.json`: `method` (`HEA` or `REA`), `injured_area` in hectares, `baseline_service` and `injured_service` (0..1), `injury_years`, `recovery_years`, `restoration_gain` (0..1), `restoration_years` and `discount_rate` as a fraction (0.03 means 3%). Optional: `restoration_lag` (years from the start of the injury until restoration delivers service), `restoration_unit_cost` per hectare, `currency`. If any required input is missing, ask for it. Never assume one.
-2. **Run** `npm run calc -- <params.json> --out matters/{id}/calc/{run}.json`. The calculator validates the inputs and refuses bad ones; show the user its message rather than adjusting the numbers yourself. When the record contradicts the inputs you were given, run them as given first, then each labelled alternative from its own file in `matters/{id}/inputs/`.

The calculator validates the inputs and refuses bad ones; show the user its message rather than adjusting the numbers yourself. When the record contradicts the inputs you were given, run them as given first, then each labelled alternative from its own file in `matters/{id}/inputs/`. Installed as a plugin with no Aranya workspace here, run `node "${CLAUDE_PLUGIN_ROOT}/.claude/scripts/hea-rea.mjs" <params.json>` with no `--out` and save its output, unchanged, to `matters/{id}/calc/{run}.json`.
 3. **Read the output** — debit and credit in discounted service-hectare-years, the restoration area needed, the scaling ratio, and an optional cost when an expert unit cost is supplied.
 4. **Sensitivity**: always present `range` first (area, and cost if there is one). It moves each expert input by `sensitivity_pct` one at a time, so it is not a worst case; say which rows move the result most.

 ### Catalog
 - `catalog/patches/2026-11-source-pack/QUESTIONS-FOR-COUNSEL.md` is back. Release 0.3.0 deleted it, but seven catalog notes still send readers there for Q1 to Q3.
 
+### Plugin
+- Aranya installs as a Claude Code plugin: `.claude-plugin/plugin.json` and a marketplace file. It ships the skills, the catalog and the calculator, and no hooks, because a plugin-wide write guard would block every edit in a project with no layout. Four skills say where to find the catalog and the calculator when there is no workspace.

 - The README says where Aranya comes from: the book *Evolution of Environmental Jurisprudence in India: The National Green Tribunal* (Cambridge University Press, 2025), and the aim of making REA/HEA compensation analysis free and open to anyone.

 5. **Start a matter.** Say *"Analyse this matter: untreated effluent degraded a mangrove stretch; the unit holds an EC."* Aranya checks the forum, applies the statutes, and records findings and flags under `matters/`.
 6. **Quantify.** Give the injury and restoration parameters and run `/hea-rea-calculator`; it returns the restoration scale with its range.
 
+### Or install the skills as a plugin
+
+```bash
+claude plugin marketplace add prathikcannotcode/aranya
+```
+
+```bash
+claude plugin install aranya@prathikcannotcode-aranya
+```
+
+The plugin carries the five skills (namespaced, as in `/aranya:env-catalog`), the catalog and the calculator, and they work in any project. It carries no hooks. Outside an Aranya workspace nothing enforces the write guard, schema validation or append-only flags, and the calculator's result is saved by the agent, so clone the repo for work that will reach a court.

 ## Skills
 
 Every skill is a slash command. You can also describe the task in plain English and Claude picks the right one.
