June Oven — Printing Press CLI
Prerequisites: Install the CLI
This skill drives the juneoven-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:
- Install via the Printing Press installer. It defaults binaries to
$HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:
npx -y @mvanhorn/printing-press-library install juneoven --cli-only
- Verify:
juneoven-pp-cli --version
- Ensure the reported install directory is on
$PATH for the agent/runtime that will invoke this skill.
If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:
go install github.com/mvanhorn/printing-press-library/library/devices/juneoven/cmd/juneoven-pp-cli@latest
If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.
Direct pair/preheat/watch/cancel control with no HomeKit and no June app, plus local history (record, log, curve, preheat-stats), workflow primitives (ready, eta), and named repeatable cooks (repeat). All agent-native JSON.
Unique Capabilities
These capabilities aren't available in any other tool for this API.
Cook workflow primitives
-
ready — Wait for the oven to reach its target temperature, then exit 0 (non-zero on timeout).
Lets an agent synchronously gate the next cook step on preheat completion instead of busy-waiting.
juneoven-pp-cli ready --timeout 20 --agent
-
eta — Non-blocking estimate of time until the oven reaches target, from the live climb rate.
An agent can sequence the next action off a returned ETA without blocking.
juneoven-pp-cli eta --agent
-
repeat — Save a named mode+temp(+timer) preset in local SQLite and replay it with one word.
Collapses a repeated weekly cook into a single memorable command.
juneoven-pp-cli repeat <name>
Local history the cloud never keeps
-
record — Capture the current cook (session + telemetry/camera activity) into local SQLite.
Turns ephemeral live cooks into a queryable local dataset the cloud never stores.
juneoven-pp-cli record --label sourdough --agent
-
log — List past cooks (mode, target, duration, outcome) from local history.
Answers historical questions about the oven that are impossible through June's API.
juneoven-pp-cli log --since 7d --agent
-
curve — Export one recorded cook's temperature/progress samples as JSON or CSV.
Gives a plottable series for one cook, for analysis or piping.
juneoven-pp-cli curve 3 --format csv
-
preheat-stats — Median/fastest/slowest time-to-target per cook over recorded cooks.
Shows how your specific oven performs over time and whether it is degrading.
juneoven-pp-cli preheat-stats --cook bake --agent
Recipes
Preheat and record
juneoven-pp-cli preheat --temp 450 && juneoven-pp-cli record --label pizza
Start a cook and capture its session to local history.
Weekly cook by name
juneoven-pp-cli repeat sunday-roast
Replay a saved mode+temp+timer preset in one command.
Export a cook's curve
juneoven-pp-cli curve 3 --format csv --agent --select ts,cavity_f
Pull one session's temperature series as CSV for plotting.
Command Reference
Control a June oven directly over June's cloud. No HomeKit, no June phone app. Temperatures are °F by default; add --celsius where a temperature is taken.
juneoven-pp-cli pair — Pair this CLI with your oven by typing an 8-digit code on its screen. Run once; credentials are stored at 0600 and control the oven.juneoven-pp-cli status — Connection state, idle/active, and current target temperature.juneoven-pp-cli preheat --temp 350 — Start a cook (--mode bake or roast). Reports the oven's ack (success/not-allowed).juneoven-pp-cli temp --temp 375 — Change the target of the active cook (June may reject a live retarget with not-allowed).juneoven-pp-cli timer --minutes 10 — Set a cook timer.juneoven-pp-cli cancel — Stop the active cook. not-allowed when already idle (reported as a normal result, not an error).juneoven-pp-cli watch --seconds 120 — Stream live telemetry and camera-frame events as JSON lines until the cook ends or the timeout elapses.juneoven-pp-cli cam --timeout 15 — Print the next interior camera frame's signed URL (frames are typically pushed only during an active cook).
Every command supports --json / --agent for structured output. Command acks come back as {"action","acked","status"}; status is the oven's own verdict.
Unique Capabilities
June's cloud keeps only live state and no history. These commands add a durable local record (SQLite) and workflow primitives no other June tool offers:
juneoven-pp-cli record --label sourdough — Capture the current cook (session + activity) into local history. The only durable record; the cloud stores none.juneoven-pp-cli log --since 7d — List past cooks (mode, target, duration, outcome). Impossible via June's API.juneoven-pp-cli repeat <name> — Save (--save <name> --mode --temp --timer) and replay named cooks in one word. --list shows saved presets.juneoven-pp-cli ready --timeout 20 — Block until the oven reaches target, typed exit (0 ready, 4 timeout). Gate an agent step on preheat completion.juneoven-pp-cli eta — Non-blocking predicted time-to-ready from the live climb rate.juneoven-pp-cli curve <session-id> --format csv — Export one recorded cook's temperature curve.juneoven-pp-cli preheat-stats --cook bake — Median/fastest/slowest time-to-target per cook over recorded cooks.
Firmware note (important): ready, eta, curve, and preheat-stats need an oven that streams live cavity-temperature telemetry. Some firmware (e.g. the penguin model) streams only interior camera frames and no temperature; on those ovens these four commands return an honest empty/notice result rather than data, while record, log, and repeat work fully. status, preheat, temp, timer, cancel, watch, and cam work on all paired ovens.
Finding the right command
When you know what you want to do but not which command does it, ask the CLI directly:
juneoven-pp-cli which "<capability in your own words>"
which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.
Auth Setup
Auth is direct pairing: run juneoven-pp-cli pair once and type an 8-digit code on the oven. A signing key and access token are stored at ~/.config/juneoven-pp-cli/identity.json (0600).
Run juneoven-pp-cli doctor to verify setup.
Agent Mode
Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.
-
Pipeable — JSON on stdout, errors on stderr
-
Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:
juneoven-pp-cli status --agent --select state,target_f
-
Previewable — --dry-run shows the request without sending
-
Offline-friendly — sync/search commands can use the local SQLite store when available
-
Non-interactive — never prompts, every input is a flag
-
Explicit retries — use --idempotent only when an already-existing create should count as success
Response envelope
Commands that read from the local store or the API wrap output in a provenance envelope:
{
"meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
"results": <data>
}
Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.
Paths and state
Agents should treat the CLI's path resolver as part of the runtime contract:
-
Use --home <dir> for one invocation, or set JUNEOVEN_HOME=<dir> to relocate all four path kinds under one root.
-
Use per-kind env vars only when a specific kind must diverge: JUNEOVEN_CONFIG_DIR, JUNEOVEN_DATA_DIR, JUNEOVEN_STATE_DIR, JUNEOVEN_CACHE_DIR.
-
Resolution order is per-kind env var, --home, JUNEOVEN_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.
-
config contains settings like config.toml and profiles. data contains credentials.toml, data.db, cookies, and auth sidecars. state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.
-
Stored secrets live in credentials.toml under the data dir. Existing legacy config.toml secrets are read for compatibility and leave config.toml on the first auth write.
-
Run juneoven-pp-cli doctor --fail-on warn to surface path and credential-location warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.
-
For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:
{
"mcpServers": {
"juneoven": {
"command": "juneoven-pp-mcp",
"env": {
"JUNEOVEN_HOME": "/srv/juneoven"
}
}
}
}
Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use JUNEOVEN_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing JUNEOVEN_HOME, or doctor will not find credentials left under the former root.
Automatic learning
This CLI ships a self-capturing learning loop. The CLI does its own bookkeeping: every invocation is journaled locally, a failed flag followed by a corrected retry auto-derives a flag_alias candidate, and a teach on a query family without a playbook auto-synthesizes a playbook_candidate from the session's journal. Your job is judgment only: recall first, act on surfaced candidates, teach the final answer, playbook amend when you observe a correction. You never record failures by hand.
Step 1: recall before any discovery
Before list/search/drill commands on a new user question, run:
juneoven-pp-cli recall "<user's question>" --agent
The response envelope:
{
"query": "...",
"normalized": "<normalized form>",
"query_entities": ["..."],
"found": true | false,
"match_score": 0.0,
"results": [
{ "resource_id": "...", "resource_type": "...", "venue": "...",
"confidence": 2, "entity_match": "exact|partial|unknown",
"source": "taught|preseed|pattern", "warnings": ["..."] }
],
"mismatches": [ ],
"warnings": [ ],
"candidates": [
{ "id": 12, "class": "flag_alias | playbook_candidate",
"summary": "...", "sightings": 3, "last_seen": "...",
"rationale": "...",
"next_action": ["<trial command>", "juneoven-pp-cli learnings confirm 12"] }
],
"playbook": {
"query_family": "...",
"playbook": {
"steps": [ { "cmd": "<command with {slot} substitution>", "purpose": "..." } ],
"entity_slots": ["$ENTITY"],
"expected_tool_calls": 3
},
"slots_resolved": { "$ENTITY": { "token": "<live token>", "canonical": "<canonical>" } },
"notes": "<workarounds + gotchas for this query family>"
},
"notes": "<duplicate surface for non-playbook callers>"
}
Empty-store short-circuit: if the store has no learnings, playbooks, or candidates yet (recall finds nothing and learnings list and learnings candidates are both empty), skip recall for the rest of this session instead of taxing every query; resume recall-first once something has been taught.
Step 2: decision tree
Read candidates, playbook, notes, results[0], and warnings in that order:
if Candidates present (warnings include "candidates_present"):
-> candidates are try-then-confirm, never facts. Follow each candidate's
two-step next_action verbatim: run the trial command first, then run
`learnings confirm <id>` only after the trial verified the behavior.
Reject a wrong candidate with `learnings reject <id>`.
-> NEVER re-teach something recall surfaced as a candidate; confirm or
reject that candidate instead of teaching a duplicate.
-> candidates ride alongside playbooks and resource hits, not instead of
them; continue with the branches below after acting on them.
if Playbook present:
-> READ Playbook.notes verbatim FIRST (workarounds + gotchas the CLI surface doesn't expose)
-> replay Playbook.steps in order, substituting Playbook.slots_resolved entries
for the entity slot tokens. If a step's slot is unresolved, fall back to
discovery for that step only.
-> the Playbook's expected_tool_calls is a budget; if you find yourself running
materially more, record the divergence via `juneoven-pp-cli playbook amend`
at end-of-session.
elif Notes present (no Playbook):
-> read Notes verbatim before any discovery step; they carry known gotchas
for this query family even when no structured choreography exists yet.
elif Found AND Results[0].EntityMatch == "exact" AND Results[0].Confidence >= 2:
-> skip discovery; fetch live data for Results[*].ResourceID in parallel
elif Found AND Results[0].EntityMatch == "partial":
-> candidate hint, NOT a hit; read the resource title to validate before trusting
elif (any row in Mismatches[] when --debug-mismatches was passed):
-> treat as cold start; the stored learning is for a different entity
(different canonical resolved from query_entities)
else: // Found == false, no playbook, no notes
-> cold start; run discovery normally; teach the answer afterward (Step 4).
If the family has no playbook yet, that teach auto-synthesizes a
playbook candidate from this session's journal - you do not need to
record one by hand.
Playbook and Notes are orthogonal to the per-resource path. A recall response can carry both a Playbook AND a Results[] hit - use both: the Playbook tells you which choreography to run; the resource hits short-circuit specific steps. Default to skipping mismatches; pass --debug-mismatches only when investigating cold-start surprises.
Candidate judgment details: learnings confirm <id> prints the candidate's full payload before materializing it - check that the printed payload matches the behavior you verified. learnings reject <id> tombstones the derivation signature so the same candidate does not resurface. The envelope carries only the few candidates worth acting on now; juneoven-pp-cli learnings candidates lists the full open set.
Graceful degradation: if learnings confirm is an unknown command, you are driving an older binary - ignore the candidates guidance and follow the rest of the protocol.
Step 3: always read warnings
low_confidence: row exists at confidence<2. Treat as a hint, not a skip-discovery hit.resource_not_in_store: the local store doesn't have the resource the learning points at. The match validator couldn't classify entities — direct-fetch and re-evaluate.cross_alias_match (per-result): the row was taught under a different alias and matched the live query's canonical via entity_lookups (e.g., a "USA" teach satisfying a "United States" recall). Trust the resource_id.similar_shape_different_entity:<canonical> (top-level): a structurally matching row exists but its canonical entity differs from the live query's. Treated as cold start; the warning carries the conflicting canonical as a hint, but the row is NOT promoted into Results.ambiguous_alias (top-level): a single query entity resolved to multiple canonicals (e.g., "Cards" → Arizona Cardinals + St. Louis Cardinals). Surface the ambiguity from context before committing to a resource.candidates_present (top-level): the envelope carries a candidates section. Handle it via the candidates branch in Step 2 before anything else.lookup_refresh_available (top-level): an entity in the query has no lookup row yet, but synced data could provide one. Run juneoven-pp-cli sync to refresh entity lookups.- Top-level
no_learnings_for_query_family: the table had no rows above the Jaccard floor. Pure cold start.
Step 4: teach & after finalizing your response - always
Teaching is unconditional. After resolving a query the store could not answer, background-teach the final resource mapping - no call-count threshold, no judging whether it was "worth" learning. The teach is the anchor of the loop: it triggers playbook synthesis for a family without a playbook, and same-referent phrasings fold into one family so near-duplicate teaches do not fragment the store. Fire it after assembling your user-facing response but BEFORE emitting it, with a shell & so the call returns immediately:
juneoven-pp-cli teach --query "<user's question>" --resource-type <type> --resource <id1> --resource <id2>
Silent on success. Errors only land in teach.log under the resolved state dir. Teach the most specific resource - if the user asked a broad question and you walked through parent records to find the specific answer, teach the leaf id, not the parent. The CLI uses seeded entity_lookups for cross-alias resolution at recall time, so a teach under one alias (e.g., "Niners") satisfies future queries under another alias (e.g., "49ers", "San Francisco") automatically.
PII rule: teach the structural question with identifiers stripped - never include names, emails, phone numbers, account ids, or other personal identifiers in taught queries or notes. The CLI scans teach queries for obvious email/phone shapes and warns, but does not block; strip before teaching rather than relying on the warning.
Step 5: playbooks - optional flags, automatic synthesis
You do not need to decide whether a session "deserves" a playbook: a teach on a family without one auto-synthesizes a playbook_candidate from the session's journal, and the next session judges it via confirm/reject. Attach explicit playbook flags only when you already hold choreography worth recording verbatim - workarounds the CLI didn't surface (silently-dropped flags, undocumented params, pagination tricks, payload gotchas). Prefer the integrated one-call form - record the resource learning and the playbook in the same teach invocation:
juneoven-pp-cli teach \
--query "<user's question>" \
--resource <id> \
--playbook-file ~/playbooks/<shape>.json \
--playbook-notes-file ~/playbooks/<shape>-notes.md
juneoven-pp-cli teach-playbook \
--query "<user's question>" \
--playbook-file ~/playbooks/<shape>.json \
--notes-file ~/playbooks/<shape>-notes.md
Playbook files are JSON with steps, entity_slots, expected_tool_calls. Notes files are markdown carrying the gotchas verbatim. File-free callers (MCP-only agents) pass the same content inline: --playbook-json and --playbook-notes on the integrated teach form, --playbook-json and --notes on teach-playbook. On the integrated teach form, the playbook flags are optional - omit them entirely for a resource-only teach. On the standalone teach-playbook form, at least one of the playbook and notes flags must be set; both empty is rejected. Playbooks are keyed on the structural query family (entities stripped) so a recipe taught from one entity-shaped query applies to every other query of the same shape, with slots_resolved binding the live query's canonical at recall time.
When you DO find a playbook on a future recall, treat it as ground truth: replay the steps with slots_resolved substitutions, skip the discovery that the choreography already documents, and read notes before any step.
Step 6: playbook amend & when your debug response identifies a correction
If your debug-protocol response identifies a concrete correction the notes or playbook should know — a workaround, an undocumented endpoint shape, a stale field name, observed schema drift, an empty-payload fallback — fire playbook amend BEFORE emitting your user-facing response. Same fire-and-forget posture as teach.
juneoven-pp-cli playbook amend \
--query "<exact recall query string>" \
--add-note "<your concrete correction>"
What counts as worth amending: a behavior you OBSERVED this session that future-you would benefit from knowing. Examples worth amending:
- A workaround for a CLI surface that silently drops or misorders a flag.
- An undocumented endpoint shape (response wrapped in
{meta, results}, payload nested two levels deeper than the docs claim).
- Observed schema drift (a field renamed, an index that shifted between seasons, a category label that the API now returns lower-cased).
What does NOT belong in notes:
- The year-specific or entity-specific answer to the user's question. That's the response, not a learning.
- Per-team / per-athlete / per-row data the playbook already retrieves at runtime.
- Statements that paraphrase what the existing notes already say.
The amend command appends to the family's existing notes with a timestamped marker ([amend YYYY-MM-DDTHH:MMZ]: <text>). Multiple amends accumulate; the audit trail is visible. If no playbook exists yet for the family, amend creates a notes-only one (so cold-start corrections still land).
PII discipline for amend notes
playbook amend notes are designed to potentially flow upstream as shared knowledge in future versions of the Printing Press. Keep them clean of user-identifying content so the upstream-contribution path stays open without retroactive scrubbing:
- Do NOT embed paths to user filesystems, personal API keys or tokens, user email addresses, user GitHub handles, or specific query histories tied to a single user.
- Acceptable: endpoint shapes, undocumented field names, API gotchas, observed schema drift, workarounds for CLI surfaces, generalizable pagination or retry tactics.
If a correction is only meaningful with user-specific context, it belongs in a personal note, not in the playbook amend.
Measuring the loop
juneoven-pp-cli learnings stats reports recall hit rate, teach-to-reuse, playbook resolution rate, and candidate confirm/reject counts from the local learn_events table. Rates are null until they have a denominator; everything stays on this machine. Use it to check whether the loop is earning its keep for this CLI.
Disabling learning
--no-learn on a single command short-circuits both recall and the teach write path. Use for deterministic agent flows or tests that must not be affected by accumulated learnings.JUNEOVEN_NO_LEARN=true in the environment globally disables the pipeline.
Agent Feedback
When you (or the agent) notice something off about this CLI, record it:
juneoven-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
juneoven-pp-cli feedback --stdin < notes.txt
juneoven-pp-cli feedback list --json --limit 10
Entries are stored locally as feedback.jsonl under the resolved data dir. They are never POSTed unless JUNEOVEN_FEEDBACK_ENDPOINT is set AND either --send is passed or JUNEOVEN_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.
Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.
Output Delivery
Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:
| Sink | Effect |
|---|
stdout | Default; write to stdout only |
file:<path> | Atomically write output to <path> (tmp + rename) |
webhook:<url> | POST the output body to the URL (application/json or application/x-ndjson when --compact) |
Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.
Named Profiles
A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.
juneoven-pp-cli profile save briefing --json
juneoven-pp-cli --profile briefing devices associated mock-value
juneoven-pp-cli profile list --json
juneoven-pp-cli profile show briefing
juneoven-pp-cli profile delete briefing --yes
Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
