 # opc-skills
 
-**Multi-target** skill manager for **opencode** + **Claude Code**. Single source-of-truth (parked archive in the personas repo), per-target lazy activation. Default operations target both platforms.
+**Multi-target** skill manager for **opencode** + **Claude Code** + **Feynman**. Single source-of-truth (parked archive in the personas repo), per-target lazy activation. Default operations target all three platforms; an interactive target-picker prompts when picking via fzf.
 
 ## Why
 
-opencode (≥1.14) auto-scans `~/.claude/skills/` as well as its own `~/.config/opencode/skills/` — so a 1000-skill Claude Code archive ends up bloating the opencode prompt. opc-skills inverts this: keep both target dirs *empty by default*, copy individual skills into them on demand.
+opencode (≥1.14) auto-scans `~/.claude/skills/` as well as its own `~/.config/opencode/skills/` — so a 1000-skill Claude Code archive ends up bloating the opencode prompt. Feynman has its own `~/.feynman/agent/skills/`. opc-skills inverts this: keep all three target dirs *empty by default*, copy individual skills into them on demand.

+#### `pick` flow
+
+1. Choose a verb-prefix category (`performing`, `detecting`, …)
+2. fzf shows skills in that category — `TAB` toggles, `ENTER` confirms
+3. **Target picker** appears: `all` / `opencode` / `claude` / `feynman` — `TAB` for multi-select; `ENTER` on highlighted `all` (default) sends to all three
+4. Selected skills are enabled in the chosen target(s)
+
+#### `disable-pick` flow
+
+Now multi-target aware: lists the **union of all active skills across the three targets**, with each entry annotated `[oc,cl,fy]` showing where it's currently active. After multi-select, the same target picker decides which target(s) to remove from.
+
 `fzf` is required for the interactive commands; `jq` for the bulk-by-axis commands; `python3` (with optional `PyYAML`) for `reindex`.
 
 ### INDEX schema
 
-`reindex` parses each `SKILL.md` frontmatter and emits records with: `folder`, `name`, `description`, `domain`, `subdomain`, `tags[]`, `status`. `enable` / `disable` perform an incremental status update on `INDEX.json` so `enable-domain` / `disable-tag` etc. stay accurate without a full reindex.
+`reindex` parses each `SKILL.md` frontmatter and emits records with: `folder`, `name`, `description`, `domain`, `subdomain`, `tags[]`, `active[]` (per-target list — `opencode`/`claude`/`feynman`), `status`. `enable` / `disable` perform an incremental status update on `INDEX.json` so `enable-domain` / `disable-tag` etc. stay accurate without a full reindex.
 
 ## Shared reference files
 
-Some skills reference sibling files via `../<name>.md` (e.g. the 20 Feynman research skills use `../_platform-mapping.md` for cross-platform tool mapping). `opc-skills enable` auto-syncs any such files from PARKED → ACTIVE so the relative references keep resolving.

 Currently synced:
 - `_platform-mapping.md` — Feynman-skills cross-platform subagent/scheduling/persistence mapping
 
-If you add new shared-reference files at the PARKED root, extend `sync_shared_refs()` in `bin/opc-skills`.

+
+## Implementation notes
+
+- `fzf` placeholder `{}` is shell-escaped automatically — preview commands use `"$PARKED"/{}/SKILL.md` (variable quoted, `{}` unquoted) so bash concatenation produces a clean path. Wrapping `{}` in extra quotes (`"$PARKED/{}/SKILL.md"`) embeds fzf's escape literals into the path and breaks preview.
