Skills¶
Skills shape the agent's workflow around recurring research tasks. They are
Claude Code and Codex slash commands. They no longer ship inside
lightcone-cli. They live in the
LightconeResearch/agent-skills
marketplace and install as plugins.
lc init registers the marketplace globally with each harness, then activates
the plugin per project. On Claude Code it runs claude plugin marketplace add
(global) and writes enabledPlugins into the project's .claude/settings.json,
so Claude Code loads the lightcone plugin when you trust the folder. On Codex it
runs codex plugin (global) when codex is on PATH. See
Install for the by-hand commands.
Plugins¶
The marketplace ships three plugins.
| Plugin | Skills | Notes |
|---|---|---|
astra |
astra |
Standalone ASTRA authoring skill. Ships the validate-on-save and activate-on-read hooks. |
lightcone (recommended) |
new, report, cli, feedback |
Bundles astra. Ships the session hooks plus the lc-extractor subagent. This one plugin is all you need for interactive work. |
lightcone-experimental |
from-paper, from-code, paper-extraction, ralph, check-sentence-by-sentence, figure-comparison |
Opt-in. Requires lightcone. Under active development. |
Skills¶
Plugin skills are namespaced by plugin. Install lightcone, then use these.
| Skill | Command | What it does |
|---|---|---|
new |
/lightcone:new |
Scope a research question into an astra.yaml, with optional literature extraction. |
report |
/lightcone:report |
Author the MyST report that references astra.yaml elements by path. |
cli |
/lightcone:cli |
The lc execution reference — spec–code invariant, status interpretation, failure diagnosis. |
feedback |
/lightcone:feedback |
File a bug report with version and error context. |
astra |
/lightcone:astra |
Author an astra.yaml — orientation and judgment (bundled from the astra plugin). |
The lightcone-experimental plugin adds /lightcone-experimental:from-paper,
/lightcone-experimental:from-code, /lightcone-experimental:paper-extraction,
/lightcone-experimental:ralph,
/lightcone-experimental:check-sentence-by-sentence, and
/lightcone-experimental:figure-comparison.
Authoring¶
Skill sources, helper scripts, and authoring guidance now live in the
agent-skills repository.
Each skill follows the open Agent Skills standard — a
SKILL.md plus optional references/, scripts/, and assets/.
