Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (37)

`baluster_spacing_calculator`	Equal baluster/spindle spacing for a run: number of balusters, exact gap and positions. Enforces a maximum gap (e.g. the 4-inch / 100 mm sphere code rule).
`board_feet_calculator`	Calculate board feet and lumber cost (thickness x width x length / 144 in inches). Accepts multiple boards and an optional price quoted per board foot or per MBF (thousand board feet).
`bom_costing`	Bill-of-materials cost roll-up for furniture: buy quantity = net qty x (1 + waste%, verified presets: S4S lumber 18%, rough 28%, nested panels 10%, hardware 3%), line and total costs, cost per product and a selling price from a target margin (price = cost / (1 - margin)).
`cbm_shipment`	Packing CBM for cartons: per-line and lot volume (m3), total weight and lot density, with a cube-out / weigh-out verdict against the 40HC balanced density (390 kg/m3 - same presets as container loading).
`cnc_feeds_speeds`	CNC spindle RPM and feed rate from tool diameter, flute count, chip load and cutting speed. Works for routers and mills, metric and imperial.
`container_loading`	How many uniform cartons fit in a shipping container before cube-out or weigh-out. Presets: 20GP (33.2 CBM nominal, 28,200 kg payload), 40GP (67.7 CBM, 26,700 kg), 40HC (76.4 CBM, 68 usable, 26,500 kg) — all editable. Returns max pieces by volume vs weight, the binding limit, balanced density (kg/m3) and containers needed for a planned quantity.
`cutting_speed_calculator`	Cutting speed from spindle speed: Vc = piDn/1000 metric (m/min), SFM = piDn/12 imperial. Always also returns the same speed converted to the other unit system. Includes a web_url with the calculation prefilled.
`embroidery_resize`	Resize an embroidery design file (PES or DST) by a scale percentage. Returns stitch stats before/after, a density safety verdict (safe within +/-15%) and the resized file as base64.
`firewood_calculator`	Convert firewood volume between cord (128 ft3), stere/Raummeter (stacked m3), solid m3 (Festmeter), loose m3 and ft3, with optional weight estimate by wood species (dry/fresh).
`flooring_calculator`	Laminate/vinyl plank takeoff: planks, boxes and cost with offcut reuse between rows (best-fit), expansion gap, layout waste presets and direction.
`glass_price_calculator`	Cut-to-size glass cost and weight estimate: net area with optional waste allowance, weight (2.5 kg/m2 per mm of thickness), material cost from your price per m2, optional polished-edge work per running metre, total and per-piece cost. Includes a web_url with the quote prefilled.
`glue_consumption`	Wood adhesive quantity: bond area x spread (g/m2, TDS presets like PVAc D3 175, EGP 250, finger-joint PUR 530) x application faces x waste allowance. Also computes bond area for edge-glued panels (joints from board width) and face lamination lay-ups.
`green_log_weight`	Weight of a roundwood/log batch at any moisture content: W = volume x basic density x (1 + MC/100), per USDA Wood Handbook 2021 Ch.4. Presets for 14 verified species (acacia, rubberwood, eucalyptus, oak, teak, spruce...) or a custom basic density. Returns oven-dry mass, water mass and tonnes.
`hoppus_volume`	Hoppus (quarter-girth) volume of round logs from mid-length circumference and length: (C/4)^2 x L. Returns Hoppus volume, true volume (x 4/pi), Hoppus tons (50 h ft3) and a board-feet approximation, with optional quantity and value per Hoppus unit.
`jas_log_scale`	Japanese Agricultural Standard (JAS) log scale: official diameter rounding (floor to 1 cm below 14 cm, even 2 cm at 14 cm and above), oval-log averaging, optional +2 cm ovality adjustment and the length allowance for logs over 6 m. Volume per log and totals in m3.
`kiln_capacity`	Kiln charge capacity: wood volume per batch (AH-188 / TechDrying). V_wood = D×R×C × t/(t+s) × f where t=board thickness, s=sticker thickness, f=fill factor (0.85–0.95). Returns wood volume in m³ and board feet (1 m³ = 423.77 BF).
`linear_cutting_optimizer`	Optimize 1D cutting plans for bars, pipes and profiles (linear cutting stock problem, best-fit decreasing heuristic). Returns bars used, per-bar cut lists with positions, total waste and unplaced parts. A web_url with the plan prefilled is included for a visual SVG diagram.
`log_volume`	Cubic volume of a log by classical formula: Huber (mid diameter only), Smalian (both end diameters) or Newton (all three, most accurate). Metric (cm, m) or imperial (in, ft); returns volume in m3 and ft3.
`lumber_weight_calculator`	Weight of lumber by species, dimensions, quantity and moisture (dry/fresh), using species density tables. Optional custom density in kg/m3.
`manufacturing_yield`	Cumulative yield through a wood production chain (sawing -> drying -> machining -> finishing). Multiplies stage yields, shows per-stage loss and computes the roundwood volume needed for a target finished volume.
`metal_weight_calculator`	Weight of metal stock per profile: pipe/tube (OD + wall), round bar, square/rectangular tube, flat bar, angle, beam/I-beam. Materials: steel, stainless, aluminum, copper, brass.
`miter_angle_calculator`	Miter angles three ways: corner mode (any corner angle between two pieces), sides mode (regular polygon with N sides), crown mode (miter + bevel for crown molding at a spring angle).
`moisture_content`	Wood moisture content (WH-2021 Ch.4 Eq. 4-1..4-4). Two modes: (1) sample-based MC_od/MC_wb from wet+dry masses; (2) drying outcome — mass + water lost when going from start MC to target MC. Optional Gb (kg/m³) returns MCmax and MCsink. Basis 'od' (oven-dry, industry default) or 'wb' (wet).
`paint_coverage`	Wood finishing paint quantity. Technical route: theoretical coverage = 10 x %volume solids / DFT(um), multiplied by transfer efficiency (conventional spray 30-35%, airless ~50%, HVLP ~65-90%, brush/roller ~90%); or a data-sheet coverage in m2/L. Adds an optional extra % for carved/3D surfaces.
`rebar_takeoff`	Rebar weight takeoff (d2/162 rule): total length, weight in kg and bars per tonne for a list of rebar lines. Supports metric mm bars and US # sizes as diameters.
`rough_sizing`	Rough sizing — convert between finished (planed, kiln-dried) and rough-sawn dimensions before drying and planing. Adds planing allowance (default 2.5 mm/face) + saw kerf (default 2.2 mm band) and applies WH-2021 Eq. 4-9 shrinkage. Direction: tangential (board width) or radial (board thickness).
`rpm_calculator`	Spindle speed (RPM) from cutting speed: n = Vc1000/(piD) metric, n = Vc12/(piD) imperial. Metric takes diameter in mm and Vc in m/min; imperial takes diameter in inches and Vc in SFM. Includes a web_url with the calculation prefilled.
`sawmill_recovery`	Sawmill recovery rate (lumber recovery factor): sawn volume out / roundwood volume in, benchmarked against FAO/EU/SE-Asia reference ranges. Also computes log-rule overrun/underrun: (actual BF - rule BF) / rule BF — Doyle underestimates small logs, so overrun is usually positive.
`sheet_cutting_optimizer`	Optimize 2D guillotine cutting plans for plywood, MDF, glass, sheet metal (2D nesting with kerf, per-part rotation lock for grain direction, optional sheet trim and multiple stock sizes). Returns sheets used, piece positions, utilization, estimated cut length/count and unplaced pieces. Includes a web_url with the plan prefilled for a visual layout diagram.
`sheet_metal_gauge`	Convert sheet metal gauge to thickness (mm) or thickness to gauge, and compute sheet weight for steel, stainless, aluminum or galvanized steel.
`stowage_factor`	Stowage factor SF = cargo volume (m3) / cargo mass (tonnes), with classification against the IMO CSS Code Table 4.1 reference ranges for wood cargoes (sawn timber, tropical logs, plywood...).
`tile_calculator`	Tiles, boxes and cost for a room: room and tile dimensions, grout width, waste factor by layout pattern (straight, offset, diagonal, herringbone...), optional box size and prices.
`timber_beam_capacity`	Allowable load on a simply supported rectangular timber beam (planning estimate, Eurocode 5 conventions, EN 338 grades C16-D40/D24-D40). Returns allowable UDL and center point load (gross and net of self-weight), governing mode (bending vs deflection at L/300), utilization, section properties. NOT a structural design - verify with an engineer. Includes a web_url with the beam prefilled.
`timber_unit_converter`	Convert timber quantities between m3, ft3, board feet, MBF, Hoppus ft3, Hoppus m3 and Hoppus tons, and translate a price quoted in any unit into $/m3 and $/MBF (1 MBF = 2.3597 m3).
`wallpaper_calculator`	Wallpaper rolls needed for a wall, accounting for pattern repeat and openings. Use a standard roll preset (eu, us-single, us-double, commercial54) or custom roll dimensions.
`wood_emc`	Equilibrium moisture content (EMC) from temperature and RH using the Hailwood–Horrobin sorption model (Simpson 1973 coefficients, desorption branch — WH-2021 Ch.4 Table 4-2). Optional reverse mode: target MC → required RH at the given temperature.
`wood_shrinkage`	Wood shrinkage from a start MC to an end MC (WH-2021 Eq. 4-9: S_x = S_od × (1 − x/FSP)). Direction: tangential (board width) or radial (board thickness) or volumetric. Picks a species from the wood-species table (16 verified species) or accepts custom S_od + FSP. MC is clamped to FSP — above FSP wood doesn't change dimension.
