• register_grinder

  Register a manual or electric grinder with its dial settings scheme. It becomes the active grinder only when no grinder is in use (none active, or the active one archived); otherwise call set_active with its grinder_id to switch to it. The `active` field of the reply says which.

  Parameters:

  • name (required) — string — The name/model of the grinder, e.g. Kinu M47
  • motor_type (required) — string
  • burr_type (required) — string
  • setting_scheme (required) — string — Collar mark style: single clicks or compound (rotation.number.clicks)
  • direction_convention (required) — string
  • nominal_step (required) — number — Smallest adjustment increment (e.g. 1 click or 0.1collar units)
  • notes — string — Additional notes
  • photo — string — Photo path or URL
  • archived — integer — 1 if archived, 0 if active
  • max_value — ['number', 'null'] — Optional travel max bounds
  • min_value — ['number', 'null'] — Optional travel min bounds
  • catalog_id — string — Optional: the maintenance catalog model this is (the `id` of a catalog row, e.g. rancilio-silvia), when it was registered from the catalog. Its maintenance then comes from that model's researched record. "none" says it is not in the catalog.
  • components_spec — string — JSON mapping string representing compound adjustment math
  • microns_per_step — ['number', 'null'] — Optional mechanical burr travel microns per nominal step

• set_grinder_position destructive

  Set the current grinder collar position. source="measured" resets verification freshness. It replaces the stored position; no history of earlier positions is kept.

  Parameters:

  • grinder_id (required) — integer
  • setting_label (required) — string — Verbatim display label, e.g. "1.1.2"
  • source (required) — string — Whether setting is verified ("measured") or guess ("recalled"/"assumed")

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• register_machine

  Register an espresso or alternative preparation machine. It becomes the active machine only when no machine is in use (none active, or the active one archived); otherwise call set_active with its machine_id to switch to it. The `active` field of the reply says which.

  Parameters:

  • name (required) — string — Machine name/model, e.g. Dedica EC685
  • control_type (required) — string
  • notes — string
  • photo — string — Photo path or URL
  • tools — ['string', 'null'] — JSON or comma-separated tools, e.g., paper filters, flow control, metal mesh
  • archived — integer — 1 if archived, 0 if active
  • prep_type — string — Preparation equipment type. One of: espresso_machine, lever_press, moka_pot, aeropress, french_press, v60_dripper, cold_brew. Lower snake_case.
  • catalog_id — string — Optional: the maintenance catalog model this is (the `id` of a catalog row, e.g. rancilio-silvia), when it was registered from the catalog. Its maintenance then comes from that model's researched record. "none" says it is not in the catalog.
  • prep_style — string — Preparation style. One of: espresso, filter, immersion, percolation. Only "espresso" is diagnosed by the dialing engine (G8). Anything else is recorded but never dialed, so do not guess this field.
  • boiler_type — string
  • hardness_dh — ['number', 'null'] — Optional: the TOTAL hardness (GH) of the water this machine runs on, in °dH (German degrees; ppm as CaCO3 ÷ 17.85), as a test strip reports it. Picks the band of a maker's hardness table for descaling and filter life
  • connected_device — string — Metadata mapping to smart hardware APIs
  • basket_size_grams — number
  • built_in_grinder_id — integer — id of a grinder built into this machine (bean-to-cup / integrated grinder)

  Hints: read-only no · destructive no · idempotent no · open-world no

• set_equipment_archived

  Archive or restore a grinder, machine, water, or scale.

  Parameters:

  • kind (required) — string — The kind of equipment to archive/restore
  • id (required) — integer — The ID of the equipment
  • archived (required) — integer — 1 to archive, 0 to restore

  Hints: read-only no · destructive no · idempotent yes · open-world no

• update_grinder destructive

  Correct a registered grinder: its name, burrs, collar scheme, nominal step, layout, range or notes. Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. setting_scheme, nominal_step and components_spec describe the collar every recorded grind label is read through: call with dry_run first to see which recorded settings would read as a different position, and tell the user before saving. Saving records the change in the grinder's maintenance history; when a locked recipe's setting moves it also opens an unmeasured calibration epoch (set_maintenance_offset resolves it). The collar's current setting is marked assumed when it reads differently, or cleared when the new collar cannot read it, and measured offsets are converted when a click changes worth. Changing direction_convention is a correction: it moves no number, but every finer/coarser said about this grinder was the wrong way round.

  Parameters:

  • grinder_id (required) — integer — This account's own grinder number, from list_grinders. Never guess one.
  • fields — object
  • reason — string — Optional note, appended to this record's own notes as an ordinary line. Omit it and nothing is written.
  • dry_run — boolean — true: write nothing, and answer with what the edit would do to the settings already recorded (moved[], checked, epoch, position_moved, position_cleared, rescaled_offsets, resigned_offsets, step_ignored, direction_flipped, recipe_count)

  Hints: read-only no · destructive yes · idempotent no · open-world no

• update_machine destructive

  Correct a registered machine (its name, control type, prep type and style, basket, boiler, accessories or notes), or record where its selectors stand (settings). Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. prep_style decides whether shots on this machine are diagnosed at all: only "espresso" is. Programs are edited with register_program, the built-in grinder link is not editable here, and archiving is set_equipment_archived.

  Parameters:

  • machine_id (required) — integer — This account's own machine number, from list_machines. Never guess one.
  • fields — object
  • reason — string — Optional note, appended to this record's own notes as an ordinary line. Omit it and nothing is written.

  Hints: read-only no · destructive yes · idempotent no · open-world no

• update_scale destructive

  Correct a registered scale: its type, resolution, capacity, capabilities, build or notes. Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. The three capabilities are 1, 0, or null for "the maker never said"; leave one out rather than sending 0 when nobody knows.

  Parameters:

  • scale_id (required) — integer — This account's own scale number, from list_scales. Never guess one.
  • fields — object
  • reason — string — Optional note, appended to this record's own notes as an ordinary line. Omit it and nothing is written.

  Hints: read-only no · destructive yes · idempotent no · open-world no

• update_water destructive

  Correct a registered water: its name, type, mineral figures or notes. Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent.

  Parameters:

  • water_id (required) — integer — This account's own water number, from list_waters. Never guess one.
  • fields — object
  • reason — string — Optional note, appended to this record's own notes as an ordinary line. Omit it and nothing is written.

  Hints: read-only no · destructive yes · idempotent no · open-world no

• log_maintenance

  Log a cleaning or maintenance job against a piece of equipment. A task that takes the thing apart opens a calibration epoch, and every recipe locked before it is read through that epoch's offset. Record the offset here if you counted the clicks while reassembling, which is the one moment anybody actually knows it. Any task in the maintenance vocabulary can be logged against a grinder or machine it belongs to, including one the maker advises against, because the log records what was done. Read each piece of equipment's tasks, their intervals and their due state from list_grinders and list_machines.

  Parameters:

  • equipment_kind (required) — string — Which kind of equipment this job was done on
  • equipment_id (required) — integer — The ID of that piece of equipment
  • task (required) — string — Which maintenance job was performed
  • note — string — Optional: what you did, and anything that surprised you
  • details — object — Fields specific to this task. Which ones a task takes is published as details_fields on each task; a burr clean takes none
  • evidence — string — One line recording what the measurement rested on, e.g. "Counted 6 clicks coarser at reassembly."
  • guide_id — string — Optional: the id of the maintenance guide that was followed. Must be a guide for this task
  • offset_value — number — The correction, if you measured it now: clicks to ADD to a pre-clean reading to get the same grind today, signed along the collar's own number direction. Omit it and the epoch stays unmeasured, which is a state the app shows rather than a zero it assumes
  • performed_at — string — When it was done (ISO 8601 or YYYY-MM-DD HH:MM:SS, UTC). Defaults to now; backdating is fine
  • disturbs_zero — integer — Whether this job disturbed the reference the stored numbers are read against: for a burr clean, whether the burrs actually came out. Defaults to the task's own answer; send 0 for a wipe-down that left the collar alone
  • offset_source — string — How the offset was arrived at: pull (a reference shot), counted (clicks counted at reassembly), typed (asserted directly)

  Hints: read-only no · destructive no · idempotent no · open-world no

• set_maintenance_offset destructive

  Record how far a maintenance job moved the reference, on an entry that opened a calibration epoch. Takes an ENTRY, not a piece of equipment: the offset belongs to the event that caused it, which is what lets several of them compose for a recipe locked before all of them. Zero is a legitimate measurement and means "measured, and it had not moved". Omit offset_value entirely to clear it back to unmeasured.

  Parameters:

  • entry_id (required) — integer — The maintenance entry that opened the epoch, from list_grinders
  • source — string — How it was arrived at: pull, counted, or typed
  • evidence — string — One line recording what it rested on, e.g. "Reference pull 1.38 g/s against 1.74 g/s locked."
  • offset_value — number — Clicks to ADD to a pre-clean reading to get the same grind today, signed along the collar's own number direction. 0 records "unchanged"; omit to clear the measurement

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• set_maintenance_schedule destructive

  Set the user's own schedule for one maintenance task on one grinder or machine: their own interval, switching it off, or muting the reminder until a date. Only the keys you send in fields change; send every: null to go back to the maker's guidance and muted_until: null to unmute. Use it when the user states how often they do a task or asks to be left alone about one, never to invent an interval. The task's class, interval and due state are read back from list_grinders and list_machines.

  Parameters:

  • equipment_kind (required) — string — Which kind of equipment the task is on
  • equipment_id (required) — integer — This account's own grinder or machine number, from list_grinders or list_machines
  • task (required) — string — The task, as its value in that equipment's maintenance.tasks
  • fields — object
  • changed_at — string — Optional: when the user made this change (ISO 8601, UTC). An app sending a queued edit passes it, so an older edit never overwrites a newer one; it is then answered with applied: false

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• get_maintenance_guides read-only

  Step-by-step maintenance guides: tools, supplies, steps and warnings, in our own words with the maker's documents as sources. With no arguments, every guide for the user's current grinders and machines (and the water filter fitted in each). With guide_ids, those guides; the ids come from maintenance.tasks[].guide.id in list_grinders and list_machines. Ids that match no guide are listed under missing.

  Parameters:

  • guide_ids — array — Optional: the guides to fetch. Omit for every guide the user's equipment can use

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_maintenance_due read-only

  What maintenance is due across the user's current grinders and machines, most urgent first. Use it for "is anything due?". Only tasks with an interval compete: a task the machine counts and signals itself, one done by habit or when a symptom shows, and one the maker advises against never appear. Each item says how far along it is (ratio, done of every, on which basis), whether it is coming up (soon), and whether the interval is the user's, the maker's or ShotPulled's default.

  Parameters:

  • status — string — due (default): due or overdue, and not muted. all: every scheduled task, muted ones last

  Hints: read-only yes · destructive no · idempotent yes · open-world no

  • resolution_banded — ['integer', 'null'] — 1 when resolution_g only holds in the lowest weight band and coarsens with load. Put the ladder in notes

  Hints: read-only no · destructive no · idempotent no · open-world no

• list_scales read-only

  List registered scales for the account. The `id` on each row is the number this account knows that record by, counting from 1: safe to show, and what other tools expect back.

  Parameters:

  • status — string — Filter by status: current (unarchived), archived, or all. Defaults to current.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• register_program destructive

  Register a programmed shot button on a machine. A program cuts the shot off either by weight (program_type "volumetric", set target_volume_g) or by time (program_type "timed", set target_time_s). One machine can have a mix of both. A program_number the machine already has is overwritten with these settings; shots logged on it keep pointing at it.

  Parameters:

  • machine_id (required) — integer
  • program_number (required) — integer — Program number / button index (e.g. 1 or 2)
  • description — ['string', 'null']

  • volume_source — string — Confidence in the stored cutoff value, for either type
  • target_volume_g — ['number', 'null'] — Target yield cutoff in grams (required for volumetric programs)

  Hints: read-only no · destructive yes · idempotent no · open-world no

• register_coffee

  Register a coffee that is NOT yet in list_beans, together with its first bag. It does not switch a coffee in use: it becomes active only when no coffee is in use (none active, or the active one archived or with every bag finished); otherwise call set_active with its bean_id when the user starts brewing it. The `active` field of the reply says which. The coffee is the roaster's product (roaster, origins, variety, process, roast level, roasting type, cupping score, aromatics, roaster notes, rest window); the bag is this purchase (roast date, weight, price, state). For another bag of a coffee already on file call register_bag instead: it keeps the recipes and notes. Returns bean_id and the first bag's bag_id.

  Parameters:

  • name (required) — string
  • roast_date (required) — string — Calendar day in YYYY-MM-DD format: a day, not a timestamp
  • roast_level (required) — string
  • process_type (required) — string

  • sweetness — string — Free text; roasters usually say low, medium or high
  • product_id — string — Set by the apps. Leave out.
  • arabica_pct — number — Percent arabica, 100 for a pure arabica; the rest robusta
  • attachments — string — JSON or comma-separated list of attachments
  • frozen_note — string
  • opened_date — string — Calendar day in YYYY-MM-DD format: a day, not a timestamp
  • roast_range — string

  • rest_window_days_min — integer

  Hints: read-only no · destructive no · idempotent no · open-world no

• set_active

  Switch the active bean, grinder or machine for this account. The numbers come from list_beans, list_grinders and list_machines. Registering a coffee, grinder or machine makes it active only when nothing of that kind is in use (the `active` field of the reply says which), so call this to start using something new as well as to switch back.

  Parameters:

  • bean_id — ['integer', 'null'] — This account's own bean number, as returned by list_beans. Never guess one; null = leave unchanged
  • grinder_id — ['integer', 'null'] — This account's own grinder number, as returned by list_grinders. Never guess one; null = leave unchanged
  • machine_id — ['integer', 'null'] — This account's own machine number, as returned by list_machines. Never guess one; null = leave unchanged
  • program_id — ['integer', 'null'] — A program number from the active machine's list; switching machines clears it. null = leave unchanged

  Hints: read-only no · destructive no · idempotent yes · open-world no

• update_bean destructive

  Update a coffee's own fields (roaster, origins, roast level, rest window, notes, rating…). Bag-shaped fields sent here (state, roast_date, bag_weight_g, grams_remaining, cost…) land on the coffee's CURRENT bag. Use update_bag when it has more than one. Changing dial_category changes what the engine advises (G5, C10), so say why in the optional note.

  Parameters:

  • bean_id (required) — integer
  • fields (required) — object
  • reason — string — Optional free-text note, appended as an ordinary line to the coffee's notes, or to the current bag's bag_notes when the call changed only bag fields. Omit it and nothing is written.

  Hints: read-only no · destructive yes · idempotent no · open-world no

• get_dial_state read-only

  Retrieve current dialing state, active context, recent shots, recommendations, and locked recipes.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• log_shot

  Log an espresso or alternative shot/brew attempt. Uses the active context (bean/grinder/machine/program) unless overridden via bean_id/grinder_id/machine_id/program_id. ALWAYS pass bean_id explicitly when the user names a specific coffee, so the shot cannot land on the wrong bag. Backdate with pulled_at when the shot happened earlier. When the user reports taste (bitter, sour, harsh, hollow…), include matching sensory_tags: the diagnosis engine reads tags and metrics, not free-text flavor_notes. When the user tasted the shot and reports it as GOOD/clean (no defects), pass tasted=1 with no sensory_tags. Otherwise a tag-less, rating-less shot is filed taste-pending as if never tasted.

  Parameters:

  • dose_g (required) — number
  • yield_g (required) — number
  • time_s (required) — number
  • finish_action (required) — string
  • tds — number — Total Dissolved Solids percentage (e.g. 9.1 or 1.35)
  • bag_id — ['integer', 'null'] — Which bag of the coffee the shot came from; defaults to its current (open) bag. Bag numbers are on list_beans' bags[]
  • rating — integer
  • tasted — integer — 1 = the shot was tasted at log time. The explicit way to record a CLEAN tasting: sensory tags all describe defects, so a good shot has none. Without this flag (or a rating) it would be filed taste-pending. Tags or a rating also mark a shot as tasted; 0 (default) = taste later.
  • bean_id — ['integer', 'null'] — Override: log against this bean instead of the active one (null = active)
  • verdict — string
  • water_id — integer — Optional references to waters formulation
  • best_brew — integer — 1 if marked as best brew, 0 otherwise
  • favourite — integer — 1 if favourite, 0 otherwise
  • pulled_at — ['string', 'null'] — When the shot was actually pulled (ISO 8601 or "YYYY-MM-DD HH:MM:SS"), for backdated entries. Defaults to now (null = now). When backdating, pass the returned shot_id to diagnose_shot explicitly, because the default diagnosis target is the chronologically latest shot.
  • beverage_g — number — Yield mass excluding cup/vessel weight in grams
  • grinder_id — ['integer', 'null'] — Override: grinder used, if not the active one (null = active)
  • machine_id — ['integer', 'null'] — Override: machine used, if not the active one (null = active)
  • program_id — ['integer', 'null'] — Override: machine program used, if not the active one (null = active)
  • temp_taste — string
  • vessel_name — string — Cup/vessel name
  • bloom_time_s — number — Pre-wetting or bloom duration in seconds
  • drink_intent — string
  • flavor_notes — string
  • flow_profile — string — Opaque flow profile data (JSON/TEXT)
  • method_tools — string — JSON representation of method tools used (e.g., paper filters, screen)
  • observations — object
  • sensory_tags — array
  • temperature_c — number — Brew temperature in Celsius
  • data_confidence — string — measured = weighed/timed live; recalled = from memory; estimated = a best guess (e.g. "~25s" after missing the timer)
  • vessel_weight_g — number — Cup/vessel weight in grams
  • machine_settings — object — Only when this one shot was pulled with a selector somewhere other than the machine's recorded settings: {key: position}. The shot is otherwise stamped with those automatically; a lasting change goes through update_machine.
  • pressure_profile — string — Pressure profile description or values
  • first_drip_time_s — number — Time to first drip in seconds

  Hints: read-only no · destructive no · idempotent no · open-world no

• lock_recipe destructive

  Lock a successful shot as the reference dialing recipe for this equipment profile. It overwrites the recipe already locked for the same coffee, grinder, machine, program and drink intent, which keeps its recipe_id.

  Parameters:

  • from_shot_id (required) — integer
  • drink_intent (required) — string

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• delete_shot destructive

  Delete a logged shot from history. Restores the bean's remaining weight (which is derived from logged doses). Hard delete: there is no undo. To fix a mistake on an otherwise-valid shot, prefer update_shot over delete-and-relog.

  Parameters:

  • shot_id (required) — integer — ID of the shot to delete

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• update_shot destructive

  Correct fields on an already-logged shot in place, with no need to delete and re-log. Use for fixing a wrong dose/yield/time or grind label, re-filing a shot onto the right bean (bean_id), backfilling rating/tasting notes, or fixing the timestamp (pulled_at). Changing grind_label re-derives the numeric grind position from the shot's grinder; changing yield/time/dose/tds keeps flow rate and extraction yield consistent automatically.

  Parameters:

  • shot_id (required) — integer — ID of the shot to correct
  • fields (required) — object — Only the fields to change

  Hints: read-only no · destructive yes · idempotent yes · open-world no

• list_recipes read-only

  List recipes (all or filtered by equipment and status). The `id` on each row is the number this account knows that record by, counting from 1: safe to show, and what other tools expect back.

  Parameters:

  • status — string — Filter by status: current, archived, or all. Defaults to current.
  • bean_id — integer
  • grinder_id — integer
  • machine_id — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_stats read-only

  Get compact flat usage stats for a grinder, machine, or bean.

  Parameters:

  • scope (required) — string — The stats scope
  • id (required) — integer — The entity ID

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_grinders read-only

  List grinders registered for the account, with status filter. The `id` on each row is the number this account knows that record by, counting from 1: safe to show, and what other tools expect back. Each row carries its maintenance block: every task with its class (S schedule, H habit, Y symptom, A the machine signals it, T technician, N never, U unstated, E event), due state, and the guide to follow.

  Parameters:

  • status — string — Filter by status: current, archived, or all. Defaults to current.
  • maintenance — string — How much of each row's maintenance block to include. compact (default): every task with its class, due state, schedule and guide. full: also the maker's own words (quote, source, alternates, the interval as written).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_machines read-only

  List machines registered for the account, with status filter. The `id` on each row is the number this account knows that record by, counting from 1: safe to show, and what other tools expect back. Each row carries its maintenance block, researched per model: every task with its class, due state, what the maker forbids, and the guide to follow. `settings` lists the selectors its model has and where each stands (null: unknown model, or none).

  Parameters:

  • status — string — Filter by status: current, archived, or all. Defaults to current.
  • maintenance — string — How much of each row's maintenance block to include. compact (default): every task with its class, due state, schedule and guide. full: also the maker's own words (quote, source, alternates, the interval as written).

• list_beans read-only

  List the coffees registered for the account, with status filter. Each coffee carries its bags[] (every purchase, with its own freshness and grams left) and current_bag_id; the row's top-level roast_date, state, grams_remaining and age fields are the current bag's. The `id` on each row is the number this account knows that coffee by, counting from 1: safe to show, and what other tools expect back; bag ids are a separate series.

  Parameters:

  • status — string — Filter by status: current, archived, or all. Defaults to current.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• grinder_math read-only

  Determine steps/clicks difference and directions between setting labels (C3).

  Parameters:

  • grinder_id (required) — integer
  • from_label (required) — string
  • to_label (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• compute_age read-only

  Compute a bag's age in days off roast and its resting/staling verdict, for the coffee's current bag by default or for the bag named.

  Parameters:

  • bean_id (required) — integer
  • bag_id — ['integer', 'null'] — A bag of that coffee (from list_beans' bags[]); null = its current bag

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• diagnose_shot read-only

  Evaluate shot metrics to provide ranked hypotheses (C6) and warn on flip-flops (G2) or fatigue (G6). Resolves the SHOT's own bean (age computed at the shot's pulled_at), never the active profile, and echoes it as bean_context, so diagnosing an older or differently-filed shot is always safe. The engine reads metrics and sensory tags, NOT free-text notes, so make sure taste feedback is recorded as sensory_tags on the shot (via log_shot or update_shot) before diagnosing; otherwise an in-range shot that tastes bad will come back "balanced".

  Parameters:

  • shot_id — integer — Optional shot ID; defaults to last pulled shot.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• suggest_next_step read-only

  Retrieve the single next experiment step from the reasoning engine.

  Parameters:

  • bean_id (required) — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• log_recommendation

  Log a recommended dialing change to allow contradiction/oscillation checking (G2).

  Parameters:

  • lever (required) — string
  • direction (required) — string
  • rationale (required) — string
  • confidence (required) — string
  • cited_rules — array
  • based_on_shot — integer

  Hints: read-only no · destructive no · idempotent no · open-world no

• get_rule read-only

  Retrieve the detailed text of a specific rule from the knowledge base by its rule ID.

  Parameters:

  • rule_id (required) — string — The ID of the rule to fetch, e.g. CAT.DARK

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_kb_version read-only

  Retrieve the current version of the knowledge base.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• kb_changelog read-only

  Retrieve the changelog showing updates and version differences for the knowledge base.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• diagnose_preview read-only

  Sandbox-only diagnosis, writes nothing (no verdict, no recommendation-trail entry). Two modes: pass shot_id to dry-run a LOGGED shot (optionally overriding its sensory_tags, for the "what would this read as?" preview; the shot's own bean and its age at pulled_at are used), or pass the full metric set (bean_id, grinder_id, machine_id, grind_label, dose_g, yield_g, time_s, source) for a hypothetical shot. Identical output shape to diagnose_shot, including bean_context.

  Parameters:

  • dose_g — number — Dose in grams
  • source — string — Grinder position source. Affects G1 warning (raw mode only)
  • time_s — number — Extraction time in seconds
  • bean_id — integer — Coffee bean ID (must belong to this account)
  • shot_id — integer — Preview a logged shot by ID (dry-run; ignores the metric params below)
  • yield_g — number — Yield in grams
  • grinder_id — integer — Grinder ID (must belong to this account)
  • machine_id — integer — Machine ID (must belong to this account)
  • grind_label — string — Grinder setting label, e.g. "1.1.3"
  • sensory_tags — array — Sensory observations, e.g. ["sour","bitter"]. With shot_id: replaces the stored tags for this preview (omit to use stored; [] = none).

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_shots read-only

  List shot history with support for pagination and filtering. Every shot carries a derived taste_pending flag (1 = logged with no sensory tags, no rating, and no tasted flip: the tasting is still owed and can be backfilled with update_shot).

  Parameters:

  • limit — integer — Number of records to return (1-500)
  • offset — integer — Offset for pagination
  • filters — object

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• register_bag

  Register another bag of a coffee that is already in list_beans: the same roaster's product, bought again. It keeps the coffee's recipes, notes and history; only the purchase facts (roast date, weight, price, state) are new. Does not change the active coffee. Returns a bag_id: bag numbers are their own series, separate from bean numbers. For a coffee that is not in list_beans yet, call register_coffee instead.

  Parameters:

  • bean_id (required) — integer — This account's own coffee number, from list_beans. Never guess one.
  • roast_date (required) — string — Calendar day in YYYY-MM-DD format: a day, not a timestamp
  • ean — string
  • cost — number
  • state — string — Defaults to sealed; the first log_shot against it opens it
  • qr_code — string
  • storage — string
  • buy_date — string — Calendar day in YYYY-MM-DD format: a day, not a timestamp
  • currency — string
  • bag_notes — string — Notes about THIS bag (a batch note, where it was bought). The coffee's own description lives on the coffee, in notes.
  • product_id — string — Set by the apps. Leave out.
  • opened_date — string — Calendar day in YYYY-MM-DD format: a day, not a timestamp
  • bag_weight_g — number — Bag weight in grams
  • best_by_date — string — Calendar day in YYYY-MM-DD format: a day, not a timestamp
  • lot_revision_id — string — Set by the apps. Leave out.
  • catalog_coffee_id — string — Set by the apps. Leave out.

  Hints: read-only no · destructive no · idempotent no · open-world no

• update_bag destructive

  Change bag-level facts on one bag of a coffee: open, seal, freeze, thaw or finish it, correct its roast date, weight, grams left or price. Bag numbers come from the bags[] on list_beans (or current_bag_id). For the coffee itself (roaster, origin, roast level, rest window, notes), use update_bean.

  Parameters:

  • bag_id (required) — integer — This account's own bag number, from list_beans' bags[]. Never guess one.
  • fields (required) — object
  • reason — string — Optional free-text note, appended to this bag's notes as an ordinary line. Omit it and nothing is written.

  Hints: read-only no · destructive yes · idempotent no · open-world no

• merge_beans destructive

  Fold one coffee into another when the same coffee was registered twice. Every bag, shot, recipe and recommendation of from_bean_id moves to into_bean_id; the active coffee follows if it was the one merged away; origins move only if the target has none. Where both hold a locked recipe for the same grinder, machine, program and drink, the newer lock wins and the older is deleted. The source coffee is archived, never deleted. Irreversible: confirm both numbers with the user first (list_beans shows them).

  Parameters:

  • from_bean_id (required) — integer — The duplicate: the coffee number that will be emptied and archived
  • into_bean_id (required) — integer — The coffee number that keeps everything
  • reason — string — Optional note, recorded on the surviving coffee's notes with the merge
