opc-skills

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. 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.

For full agent / skill / persona generation across multiple AI platforms, see the upstream personas repo.

Install

ln -s ~/Documents/opc-skills/bin/opc-skills ~/.local/bin/opc-skills

Ensure ~/.local/bin is on your PATH.

Layout it expects

~/Documents/personas/skills-archive/    # full catalog — single source-of-truth
  <skill-name>/SKILL.md
  INDEX.json
  INDEX.md

~/.config/opencode/skills/              # currently-enabled (opencode target)
  <skill-name>/SKILL.md

~/.claude/skills/                       # currently-enabled (claude target)
  <skill-name>/SKILL.md

~/.feynman/agent/skills/                # currently-enabled (feynman target)
  <skill-name>/SKILL.md

(~/Documents/opencode-skills-parked is symlinked to personas/skills-archive for backward-compat.)

Override via env:

• OPC_PARKED — parked catalog root (default ~/Documents/personas/skills-archive)
• OPC_ACTIVE — opencode active dir (default ~/.config/opencode/skills)
• OPC_CLAUDE_ACTIVE — claude active dir (default ~/.claude/skills)
• OPC_FEYNMAN_ACTIVE — feynman active dir (default ~/.feynman/agent/skills)
• OPC_TARGETS — comma-separated default targets (default opencode,claude,feynman)

Targets

enable, disable, and disable-all accept --target / -t:

flag	meaning
--target opencode	only ~/.config/opencode/skills/
--target claude	only ~/.claude/skills/
--target feynman	only ~/.feynman/agent/skills/
--target all	all three
--target both	legacy opencode,claude (no feynman)
--target opencode,feynman	comma-separated subset

When omitted, the default is taken from OPC_TARGETS (default opencode,claude,feynman).

Commands

Inspection

opc-skills status                     # parked + per-target active counts (3 targets)
opc-skills list {active|parked|all}   # skill folder names
opc-skills categories                 # verb-prefix counts (performing, detecting, ...)
opc-skills domains                    # frontmatter `domain:` distribution
opc-skills subdomains                 # frontmatter `subdomain:` distribution
opc-skills tags                       # frontmatter `tags:` distribution

Single-skill operations

opc-skills enable  [--target T] <folder>           # copy parked → active in selected targets
opc-skills disable [--target T] <folder>           # remove from active in selected targets
opc-skills disable-all [--target T] [-y|--yes]     # disable every active skill across targets

Bulk by axis

opc-skills enable-category   <prefix>      # fzf multi-pick within a verb-prefix
opc-skills disable-category  <prefix>
opc-skills enable-domain     <domain>      # bulk by frontmatter domain (eg. cybersecurity)
opc-skills disable-domain    <domain>
opc-skills enable-subdomain  <subdomain>   # bulk by subdomain (eg. malware-analysis)
opc-skills disable-subdomain <subdomain>
opc-skills enable-tag  [--all] <tag>...    # bulk by tags (default: any; --all: intersection)
opc-skills disable-tag [--all] <tag>...

Interactive / search

opc-skills pick                       # fzf: category → multi-select skills → target picker → enable
opc-skills disable-pick               # fzf: union-of-actives → category → multi-select → target picker → disable
opc-skills search [query]             # fzf fuzzy over name+description (enables on selection)
opc-skills disable-search [query]     # fzf over ACTIVE only (disables on selection)
opc-skills reindex                    # rebuild INDEX.json / INDEX.md

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[], 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 in all three targets 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_to_targets() 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.

Known interaction

The personas repo's build.py --install opencode currently wipes and repopulates ~/.config/opencode/skills/ as part of installation, which destroys the active set curated here. Use opc-skills after any personas install, or skip the skills half of build.py installs.

build.py --install opencode and build.py --install claude-skills both emit _platform-mapping.md at the skills-root alongside the 20 Feynman skills (deep-research, literature-review, paper-code-audit, peer-review, paper-writing, replication, source-comparison, summarize, alpha-research, eli5, autoresearch, docker, modal-compute, runpod-compute, session-log, session-search, jobs, watch, preview, contributing).
