/agent-ecosystem-radar

Use when the user wants one pass that researches external agent tools, compares them, and recommends GroundLine upgrades for Codex, Claude Code, or Antigravity.

align-agent-home

/align-agent-home

Use when the user asks about Codex, Claude Code, or Antigravity settings, official documentation alignment, guidance files, skills, custom agents, rules, hooks, provider boundaries, private config sync, or runtime doctor output.

audit-agent-history

/audit-agent-history

Use when analyzing local Codex, Claude Code, or Antigravity history stores; when comparing current provider storage; when improving retention; when recovering prior context; or when deriving reusable skills from past agent work.

close-live-work

/close-live-work

Use when local tests or CI appear complete but dev, review, staging, production, app store, worker, queue, scheduler, or browser-visible runtime state must be proven before saying deployment or release work is done.

compare-agent-workflows

/compare-agent-workflows

Use when comparing agent tools, skills, plugins, MCP servers, hooks, workflow frameworks, or provider features against GroundLine scope and supported runtimes.

GroundLine

GroundLine helps an AI coding agent slow down at the moments that usually go wrong: resuming someone else's work, touching risky systems, claiming work is complete too early, or letting a release grow without a stop point.

GroundLine is a lightweight control plane for Codex, Claude Code, and Antigravity. It keeps capability blueprints, detects runtime and ecosystem drift, prepares research and upgrade packets, and guides agents through current-state proof, side-effect boundaries, live evidence, and handoff.

GroundLine is not a synced config dump, a heavy bootstrap CLI, or an always-on MCP bundle.

GroundLine also does not reimplement provider-native features. Built-in goal modes, subagents, hook engines, plugin installers, MCP launchers, browser controls, and app context features stay owned by Codex, Claude Code, or Antigravity. GroundLine provides the provider-neutral task contracts, safety boundaries, and verification language around them.

Start Here

If you only want to try GroundLine, do this:

git clone https://github.com/jukqaz/groundline.git
cd groundline
PYTHONDONTWRITEBYTECODE=1 python3 scripts/validate_pack.py --json
PYTHONDONTWRITEBYTECODE=1 python3 scripts/groundline_provider_smoke.py --json

validate_pack.py should report status=PASS. The provider smoke command is read-only: it should report mutation_performed=false and no real provider home writes, but it may return PARTIAL when an existing provider install is stale relative to the checked-out package. Use --require-installed when the goal is post-install release proof rather than package/path validation. Read top-level next_actions before installing or refreshing Codex, Claude Code, or Antigravity.

If you want to install from the public repository:

codex plugin marketplace add jukqaz/groundline --ref main
codex plugin add groundline@groundline

claude plugin marketplace add jukqaz/groundline
claude plugin install groundline@groundline

agy plugin install https://github.com/jukqaz/groundline

When To Use It

Use GroundLine when the next step needs evidence or a boundary:

Situation	Ask the agent
A previous agent worked on this	"Recheck the current state before continuing."
A thread is too long	"Package this task so another agent can continue."
The task keeps expanding	"Hold the line and decide what ships now."
Tests passed but the runtime may still be wrong	"Close this with live evidence."
The action may change files, remotes, production, access, or secrets	"Classify side effects before doing anything."
You are near release	"Polish the release candidate and lock the release cut."
You are comparing agent tools or skills	"Evaluate this capability before adopting it."

What Changes And What Does Not

By default, GroundLine is skills-first:

It adds skill instructions, references, docs, and validation scripts.
It does not install hooks, rules, MCP servers, slash commands, provider-level agents, or background jobs.
It does not read raw transcripts or copy provider runtime state into the repository.
It can recommend optional MCP use when a task needs live GitHub, current docs, private docs, or private code search.

Languages

English is the default and canonical language for GroundLine documentation. Korean companion docs are available for human-facing setup and workflow reading:

Korean README: README.ko.md
Korean human docs index: docs/ko/index.md
Language policy: docs/language-policy.md

LLM-readable references, output contracts, manifests, and skill instructions stay in English unless a release explicitly changes that policy.
