What it does
Firstmate Orca is an agent skill from kunchenguid/firstmate. Agent-only operator checklist for Firstmate's Orca runtime backend. Use when switching to Orca, spawning or supervising Orca-backed work, smoke-testing Orca backend behavior, debugging Orca task state, or reconciling Orca-backed task metadata.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: Talk to one agent. Ship with a crew. The licence is MIT.
When your agent uses it
- Switching to Orca
- Supervising Orca-backed work
- Smoke-testing Orca backend behavior
- Debugging Orca task state
Example prompts
- “/firstmate-orca”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Read state/.meta and the relevant status tail first.
- Confirm the task is actually Orca-backed before using Orca-specific assumptions.
- Use the recorded terminal=, orca_worktree_id=, and worktree= as the task identity.
- Prefer firstmate helpers for peek, send, state, and teardown.
- Avoid raw deletion of Orca worktrees or manual branch cleanup.
- Stop and inspect if the recorded worktree path, Orca worktree id, or project checkout no longer matches expectations.
What it can do on your machine
Read from SKILL.md and the folder at commit 19fcbbd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Firstmate Orca loads about 1.3k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 697 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

firstmate-orca
Use this as the operator checklist for Firstmate's experimental Orca runtime backend.
It does not replace AGENTS.md, docs/orca-backend.md, or harness-adapters.
Orca is a runtime backend, not an agent harness.
The runtime backend owns the task endpoint and, for Orca, the task worktree.
The harness is the agent process launched inside that endpoint, such as claude, codex, opencode, pi, pi-signed, grok, or kimi.
Load harness-adapters for harness-specific launch, interrupt, resume, trust-dialog, and skill-invocation facts.
Implementation details, metadata fields, teardown guarantees, and limitations live in docs/orca-backend.md.
docs/verification/runtime-backends.md "Orca" owns active smoke evidence.
Prefer the bin/fm-* helpers over raw orca commands.
Use raw orca only when the helper surface cannot answer the inspection question, and keep the recorded firstmate metadata as the task identity.
Preflight
Work from the current firstmate home or repo root.
If FM_HOME is set, remember that operational state lives under $FM_HOME while the helper scripts still run from this repo's bin/.
Before switching or spawning against Orca:
- Confirm Orca is intentionally selected through
--backend orca,FM_BACKEND=orca, or localconfig/backend. - Confirm the Orca app is running and the backend readiness checks pass before expecting spawn to work.
- Inspect active
state/*.metarecords before changing backend selection. - Treat a backend switch as affecting future spawns only; existing tasks keep their recorded backend.
- Reconcile watcher wakes before unrelated work, especially if Orca tasks are already in flight.
Spawn
Use bin/fm-spawn.sh so firstmate creates the brief, worktree, terminal, metadata, status file, and watcher surface together.
Pass --backend orca for a one-off Orca task, or rely on the already-selected Orca backend when that selection is intentional.
After spawn, check the task with firstmate helpers:
bin/fm-peek.sh fm-<id>for launch failures, trust dialogs, or first output.state/<id>.metaforbackend=orca,terminal=,orca_worktree_id=, andworktree=.bin/fm-crew-state.sh <id>when the current run state matters.bin/fm-watch.shwhenever there are tasks in flight and this session owns supervision.
Do not manually create the Orca worktree or terminal for a normal firstmate task. Do not manually patch metadata to make an externally-created Orca terminal look like a firstmate task.
Supervision
Use bin/fm-peek.sh, bin/fm-send.sh, bin/fm-crew-state.sh, and bin/fm-teardown.sh for routine operation.
For steer messages, use bin/fm-send.sh <id> '...'; the stable fm-<id> alias also works, and ordinary local text steers may contain newlines because they ride the durable inbox.
Keep initial scope in the task brief; a temporary file remains useful when the instruction includes supporting material the worker should inspect separately.
When supervising, treat state/<id>.meta as the routing record and Orca's own ids as backend implementation details.
The stable firstmate alias is fm-<id>.
The recorded terminal= and orca_worktree_id= fields are what backend helpers use under the hood.
If an ordinary steer fails to enqueue, or a typed-plane fm-send fails to submit, do not immediately repeat the instruction.
Read the reported failure and peek first, then decide whether the record exists or the target is busy, waiting on a prompt, stuck behind a popup, or genuinely wedged.
For harness-specific interrupts or exits, load harness-adapters.

Recovery
For a messy Orca-backed task:
- Read
state/<id>.metaand the relevant status tail first. - Confirm the task is actually Orca-backed before using Orca-specific assumptions.
- Use the recorded
terminal=,orca_worktree_id=, andworktree=as the task identity. - Prefer firstmate helpers for peek, send, state, and teardown.
- Avoid raw deletion of Orca worktrees or manual branch cleanup.
- Stop and inspect if the recorded worktree path, Orca worktree id, or project checkout no longer matches expectations.
Teardown remains governed by the normal firstmate landing rules.
Scout work can be torn down after the report exists and the captain-hold-lifecycle completion gate passes.
Ship work can be torn down only after the work is landed by its project mode.
Smoke Test
Keep Orca smoke tests focused on lifecycle plumbing:
- Select Orca intentionally for a disposable task or scout.
- Spawn through
bin/fm-spawn.sh. - Confirm metadata records the Orca backend, terminal, Orca worktree id, and isolated worktree path.
- Verify
bin/fm-peek.sh, a shortbin/fm-send.shsteer, watcher wake behavior, andbin/fm-crew-state.sh. - Tear down through
bin/fm-teardown.shafter the task is safely disposable or landed. - Restore the previous backend selection if Orca was selected only for the smoke test.
Do not mix a backend smoke test with unrelated feature work.
