Canopy is a multi-repo workspace orchestrator. When you see canopy.toml or a .canopy/ directory at the workspace root, canopy is configured. The mcp__canopy__* tools are your primary surface for repo, branch, and PR operations in that workspace.
The single biggest agent failure mode in multi-repo work is path mistakes — cd /wrong/repo && git status, git checkout in repo A when you meant repo B, pnpm test in the API repo because the previous shell call left you there. Canopy eliminates this class of bug by accepting only semantic inputs (feature, repo, alias) and resolving paths internally. You literally cannot cd to the wrong place because you never specify a path.
Canopy also returns pre-classified state: review comments are temporally filtered into actionable_threads vs likely_resolved_threads, features have computed states like ready_to_commit / drifted / awaiting_review, and every action returns structured next_actions you can follow without re-deriving the rules.
feature_resume firstWhen the user opens a chat and references a feature alias (a Linear issue ID like TEAM-101, a feature name, a slot id like worktree-1, or a PR URL/<repo>#<n>), call mcp__canopy__feature_resume(<alias>) before acting on whatever intent they've stated. This is a compound action: it resolves the alias, switches the canonical slot if it's not already there, refreshes from GitHub + Linear, and returns a structured brief with intent_hints for the most likely next actions.
Patterns that trigger this:
"TEAM-101", "TEAM-101, let's address comments", "jump into auth-flow"."I am back on TEAM-101", "resuming auth-flow".Once you have the brief, look at intent_hints (sorted by priority) and pair the top hint with what the user said. Examples:
| User says | Top hints | Your move |
|---|---|---|
| "address PR comments" | address_comments, post_drafts | call review_comments with the alias from intent_hints[0].suggested_args, then walk through actionable threads |
| "align with dev" | align_with_default | inspect current_state.branch_position_per_repo, propose rebase or merge per repo |
| (nothing specific) | (read top 3 hints) | summarize the brief + hints in 3–5 lines, ask the user which to pursue |
Do not call feature_resume more than once per session per feature unless you've done work that materially changes state (e.g. pushed, resolved a thread, posted replies). The brief is fresh-per-call (refreshes GH/Linear) so repeated calls are wasteful, not stale.
feature_resume supersedes mcp__canopy__switch as the session-start primitive — it does the switch internally plus the full brief. Use switch directly only when you want to focus a slot without the overhead of a fresh brief (e.g. mid-session slot rotation).
When you finish reviewing a thread:
commit --address <comment_id> --resolve-thread (or post-process with mcp__canopy__resolve_thread).mcp__canopy__reply_to_thread <thread_id> <body> with concrete evidence. Pass resolve_after=true when the pushback closes the discussion.| What you want to do | Canopy tool | Don't use |
|---|---|---|
| What feature should I work on right now? | mcp__canopy__triage | per-repo gh pr list + manual grouping |
| Show me everything about a feature | mcp__canopy__feature_state | composing many reads yourself |
| Promote a feature to the canonical slot (the focus primitive) | mcp__canopy__switch | cd repo && git checkout per repo, or guessing paths |
| Inspect slot occupancy (dashboard grid) | mcp__canopy__slots(rich=True) | hand-rolling ls .canopy/worktrees/ + per-slot feature_state |
| Pre-warm a cold feature into a slot without changing canonical | mcp__canopy__slot_load(feature, slot_id?) | mcp__canopy__switch (changes canonical too) |
| Free a slot without bringing a new feature in | mcp__canopy__slot_clear(slot_id) | manual stash + branch checkout |
| Exchange two slots' occupants | mcp__canopy__slot_swap(slot_a, slot_b) | two slot_load calls with replace=True |
| Migrate a pre-3.0 workspace to the slot model | mcp__canopy__migrate_slots | hand-renaming .canopy/worktrees/ dirs |
| Hibernate current focus + start something new | mcp__canopy__switch(feature, release_current=True) (release_current is the API param; user-facing label is "hibernate") | manual stash + checkout dance |
| Commit across the canonical feature (one message, all repos) | mcp__canopy__commit(message=...) (canonical feature inferred; pass feature= for non-canonical) | mcp__canopy__run(... 'git commit') per repo |
| Push the canonical feature to origin | mcp__canopy__push() (add set_upstream=True on first push; the no_upstream blocker tells you when) | mcp__canopy__run(... 'git push') per repo |
| Check whether HEADs match expected | mcp__canopy__drift | cd && git branch --show-current per repo |
| Recover from "something is off" — opaque errors, missing paths, stale state | mcp__canopy__doctor (then doctor(fix=True) if auto_fixable) | hunting through stash lists / worktree paths manually |
| Read PR review comments (temporally filtered) | mcp__canopy__github_get_pr_comments | gh api .../comments + manual filter |
| Get PR data (title, decision, draft, ...) | mcp__canopy__github_get_pr | gh pr view --json ... per repo |
| Get branch HEAD/divergence/upstream | mcp__canopy__github_get_branch | cd repo && git status -b |
| Fetch an issue (Linear / GitHub Issues — provider-agnostic) | mcp__canopy__issue_get | direct API |
| Run a shell command in a specific repo | mcp__canopy__run | cd /path && cmd (path mistake risk) |
| Stash dirty changes for a feature | mcp__canopy__stash_save_feature | raw git stash push |
| List/restore stashes by feature | mcp__canopy__stash_list_grouped / stash_pop_feature | git stash list + manual filter |
1. triage() → pick a feature from the prioritized list
2. feature_state(feature) → get current state + next_actions
3. follow next_actions[0] → primary CTA (canopy decided what to do next)
4. feature_state again → confirm state advanced
5. repeat
The next_actions array is canopy's recommendation. Trust it unless you have a specific reason not to.
Every tool that takes a feature accepts the same alias forms — learn one rule, use everywhere:
SIN-12-searchSIN-12 (resolves through the lane's linear_issue field)<repo>#<n> like backend#142https://github.com/owner/repo/pull/142<repo>:<branch> like backend:feature/xworktree-1, worktree-2, ... — resolves to the slot's current occupant (Wave 3.0). Lets you say "tell me about worktree-2" without first looking up what's in it.For features whose branch name differs across repos (e.g. SIN-13-fixes in backend vs SIN-13-fixes-v2 in frontend), the lane's branches map handles this transparently. You pass the canonical feature alias; canopy resolves per-repo branches.
Canopy organizes worktrees into numbered slots — .canopy/worktrees/worktree-1/, .canopy/worktrees/worktree-2/, etc. A slot is a stable disk resource; the feature inside it is a transient tenant. When you switch from feature X to feature Y, the slot ids don't change — only which feature occupies which slot.
Want to see what's in each slot? Call mcp__canopy__slots (defaults to rich=True) — returns the full dashboard grid in a single call: canonical + every warm slot, each with per-repo branch / dirty / ahead-behind / PR / CI / bot threads / linear / computed feature_state. Empty slots come back as explicit null.
The slot vocabulary (CLI + MCP parity):
mcp__canopy__switch(feature) — promote a feature to canonical. Slot rotation is automatic. evict_to=<slot-N> pins where the outgoing canonical lands; to_slot=<slot-N> promotes whatever feature already sits in that slot.mcp__canopy__slot_load(feature, slot_id?) — warm a cold feature into a slot without changing canonical. Use this to pre-warm a slot before review or before a planned switch. replace=True evicts the current occupant to cold first.mcp__canopy__slot_clear(slot_id) — evict that slot's occupant to cold (with feature-tagged stash if dirty). The slot itself remains.mcp__canopy__slot_swap(slot_a, slot_b) — exchange the occupants. v1 requires identical repo scope on both features.mcp__canopy__migrate_slots() — one-shot migration from a pre-3.0 workspace (where worktrees were named after their feature). Idempotent. Run once per workspace if BlockerError(code='pre_migration') ever surfaces.Canonical is the only place to run code. Slots are passive branch storage. Never cd into .canopy/worktrees/worktree-N/ to launch the app, run tests, or open a dev server — switch the feature into canonical first (mcp__canopy__switch(feature)). If you need to inspect a warm slot's files without changing focus, that's fine (read-only Read / Grep is harmless), but anything that runs the project should happen against canonical.
Canopy errors come back as:
{
"status": "blocked",
"code": "drift_detected",
"what": "branches don't match feature lane",
"expected": {...},
"actual": {...},
"fix_actions": [
{"action": "switch", "args": {"feature": "SIN-12-search"}, "safe": true, "preview": "..."}
]
}
The fix_actions array lists recommended recovery steps, ordered most-recommended first. Each entry has safe: true|false:
safe: true → you can call this directly to recover.safe: false → surface to the user before invoking (it might lose work or affect remote state).When you see a BlockerError, the first step is to read fix_actions[0] and decide whether to follow it.
If a canopy call returns an unexpected error — KeyError from a state read, a "feature not found" for one you just created, a worktree path that should exist but doesn't — call mcp__canopy__doctor first. It reports 21 codes across 12 categories of state-file drift + install-staleness (including slot-state checks added in Wave 3.0: slot_dir_orphan, slot_entry_orphan, slot_branch_mismatch, slot_detached_head), each with code, severity, expected/actual, and an auto_fixable flag.
summary.errors == 0 → not a state problem; investigate the original error normally.auto_fixable: true → call doctor(fix=True); report fixed/skipped to the user.auto_fixable: false (e.g., features_unknown_repo, branches_missing, cli_stale) → surface the issue's fix_action text. The human needs to decide.The mcp__canopy__version tool returns {cli_version, mcp_version, schema_version} for the same handshake.
If the user wants canopy to behave differently here — "use ruff for preflight", "track CodeRabbit and Korbit as bots", "the api repo runs uv run pytest tests/fast before commits" — that's a canopy.toml augment. Suggest invoking the augment-canopy skill, which knows the schema and how to mutate the file safely. Install it with canopy setup-agent --skill augment-canopy if it isn't already.
Each feature has a persistent memory file at <workspace>/.canopy/memory/<feature>.md that survives session boundaries. When you call mcp__canopy__switch(feature), the response includes a memory: <markdown> field — read it first before re-deriving anything.
Three sections in the memory: Resolutions log (per-comment outcomes — never compacted), PR context (one block per PR), and Sessions (newest first; older sessions get trimmed by historian_compact).
What to call when:
mcp__canopy__historian_decide(feature, decisions=[{title, rationale}, ...]) — after picking an approach, after a pivot, before pausing. Decisions are deduped per-session by title, so it's safe to call repeatedly.mcp__canopy__historian_pause(feature, reason) — when stopping work mid-flow. The next session reads it on switch.mcp__canopy__historian_defer_comment(feature, comment_id, reason) — when intentionally skipping a review comment for a stated reason.mcp__canopy__feature_memory(feature) — re-read the memory at any point in the same session.mcp__canopy__historian_compact(feature, keep_sessions=5) — manual trim when the file grows long. Resolutions + PR context are never compacted.Auto-capture from canopy actions (no extra calls needed):
mcp__canopy__commit(address=...) records the resolution into memory automatically (mirrors bot_resolutions.json).mcp__canopy__github_get_pr_comments(alias) records comment_read for each actionable thread + classifier_resolved for the temporal-classifier output, deduped per-session.If you decided something but forgot to call historian_decide, end the turn with a <historian-decisions>[{"title": "...", "rationale": "..."}, ...]</historian-decisions> block. A future Stop hook (autopilot) will tail-parse it and persist (deduped against the explicit calls).
When mcp__canopy__feature_state returns state awaiting_bot_resolution, only bot nits (CodeRabbit, Korbit, Cubic, etc.) are blocking — humans haven't requested changes. The summary splits the actionable count into actionable_bot_count and actionable_human_count so you can tell which side needs attention.
mcp__canopy__bot_comments_status(feature) returns the per-PR rollup: total / resolved / unresolved + per-thread metadata (id, author, file, body preview).mcp__canopy__commit(message, address=<comment-id>) (or canopy commit --address <id>) auto-suffixes the commit message with the bot comment's title + URL and persists the resolution to .canopy/state/bot_resolutions.json. Resolved comments drop out of actionable_bot_count on the next feature_state call.bot-status call has clean per-comment provenance.cd <repo> && git checkout <branch> — use mcp__canopy__switch(feature=...) so all participating repos move together with verification (and the previously-canonical feature evacuates into a warm slot, preserving its work-in-progress).cd .canopy/worktrees/worktree-N/<repo> && pnpm dev (or pytest, or any command that runs the project) — worktrees are passive branch storage. Switch the feature into canonical (mcp__canopy__switch(feature)) and run there. Read-only inspection (Read / Grep against a warm slot) is fine; execution is not.gh pr list --author @me per repo and grouping yourself — mcp__canopy__triage already groups by feature lane and applies priority tiers.cd <repo> && pnpm test — use mcp__canopy__run(repo='repo-b', command='pnpm test'). The shell state from a previous tool call is not yours.gh api .../pulls/{n}/comments and writing your own "is this resolved" logic — mcp__canopy__github_get_pr_comments returns actionable_threads vs likely_resolved_threads already.git status in each repo and synthesizing what's dirty/clean — mcp__canopy__feature_state(feature) returns this aggregated, plus computed state and next_actions.git stash push when there's a feature context — use mcp__canopy__stash_save_feature(feature, message) so stashes get tagged and groupable.mcp__canopy__run(repo='...', command='git commit ...') to commit one repo at a time — use mcp__canopy__commit(message=...) so the whole canonical feature commits with one message and the wrong-branch / hooks-failed cases come back classified.mcp__canopy__run(repo='...', command='git push') per repo — use mcp__canopy__push(). First push needs set_upstream=True; the no_upstream blocker tells you when (and the fix-action carries the same args + set_upstream=True so you can retry mechanically).A message starting with canopy: blocked means the enforcement hook stopped
a git mutation that targeted the wrong directory or branch. Do NOT retry the
same command or work around it with a different path. Read the reason — it
names the fix (usually cd <repo> && ... or canopy switch <feature>).
Use raw Bash, Read, Edit etc. as normal for:
canopy.toml)canopy.tomlcontext is your single read for the workspace map (feature ↔ repo ↔ branch
↔ path ↔ state). It's local + instant. Use it freely for orientation.context remote=True) ONLY when the task depends on
remote state — addressing PR comments, checking if CI is green, reviewing.
Local code/feature work does not need it.start <alias> begins new work (lazy: no repos until you join).canopy join <repo> when you're ready to work in a repo — it creates the
branch AND registers the repo so the enforcement gate recognizes it. A raw
git checkout -b does NOT register; context will advise you to join.context gives you the path; the enforcement gate allows
commits/pushes there. Do NOT switch — switching is only for running.canopy switch <feature> promotes it to trunk (the only place with the full env).context shows a slot's deps as installing or failed, wait or
canopy worktree-bootstrap --deps <feature> before linting/testing there.canopy reclaim frees warm slots whose PRs merged (clean ones only).
