An integrated ecosystem of CLI tools for AI agent workflows. Each tool handles one concern — expertise, issues, prompts, agents, or orchestration — and they compose together so multi-agent teams can operate autonomously on real codebases.
| Tool | CLI | npm | What it does |
|---|---|---|---|
| Mulch | mulch / ml |
 |
Structured expertise management — agents record conventions, patterns, and decisions as they work, then retrieve them at the start of each session |
| Seeds | sd |
 |
Git-native issue tracking — JSONL storage, dependency graphs, templates, zero external dependencies |
| Canopy | cn |
 |
Prompt management — version-controlled prompt composition with inheritance, pinning, and schema validation |
| Sapling | sp |
 |
Headless coding agent — proactive context management between every LLM call, pluggable backends |
| Overstory | overstory / ov |
 |
Multi-agent orchestration — spawn Claude Code agents in git worktrees via tmux, coordinate through SQLite mail, merge with conflict resolution |
overstory (orchestrates agents)
├── sapling (headless coding agent runtime)
├── mulch (stores expertise for agents)
├── seeds (tracks issues agents work on)
└── canopy (manages prompts agents use)
Overstory spawns agents (including Sapling) in isolated git worktrees. Those agents pick up work from Seeds, load project expertise from Mulch, and access managed prompts from Canopy. All five tools share the same design principles:
- Git-native storage — JSONL and YAML files that live in your repo, merge cleanly, and need no external database
- Zero runtime dependencies — each tool is a single Bun binary with no daemon or server
- Multi-agent safe — advisory file locking so concurrent agents don't corrupt shared state
- CLI-first — every operation is a shell command with
--jsonoutput for scripting and piping - Consistent UX — shared color palette, status icons, help screen layout, and flag conventions across all five tools
Requires Bun >= 1.0.
# Install all five tools
bun install -g @os-eco/mulch-cli @os-eco/seeds-cli @os-eco/canopy-cli @os-eco/sapling-cli @os-eco/overstory-cli
# Initialize in your project
cd your-project
ml init && sd init && cn init && ov init
# Verify
ml --version && sd --version && cn --version && sp version && ov --versionOr install individually — each tool works standalone:
bun install -g @os-eco/seeds-cli # just issue tracking
bun install -g @os-eco/mulch-cli # just expertise management# An agent starts a session
ml prime # load project expertise into context
sd ready # find unblocked issues to work on
sd update seed-a1b2 --status in_progress
# Agent does work, then wraps up
ml record testing --type convention \
--description "Always mock fs in unit tests"
sd close seed-a1b2
# Multi-agent orchestration
ov sling seed-c3d4 --strategy worktree # spawn an agent for an issue
ov status # monitor running agents
ov merge builder-01 # merge completed work backEach tool lives in its own sub-repo with independent git history, CI, and npm versioning. This meta-repo tracks cross-cutting concerns:
