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 in the project's .claude/settings.json.
Claude Code offers to install the lightcone plugin when you trust the folder.
See Install for the manual 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 venv and 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 |

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/.
