Start here. Explains the IRS prevailing wage and apprenticeship (PWA) requirements for the increased clean-energy credit (ITC under IRC 48 / 48E and the other IRA credits): what they are, when they apply (the 1 MW and January 29, 2023 exceptions), the prevailing wage rule, the three apprenticeship tests (labor-hours percentage, daily ratio, four-or-more participation), the good-faith exception, cu

Parameter	Type	Required	Notes
topic	string	no	all (default), what, prevailing_wage, apprenticeship, penalties, records, changes_2025 or sources.

Says whether a project must meet the prevailing wage and apprenticeship requirements to claim the increased (5x) credit, and which ones: the credit involved, when construction began (before January 29, 2023 is exempt for 30C, 45, 45Q, 45V, 45Y, 48, 48E and 179D; 45L, 45U, 45Z and 48C have no such exception), the one-megawatt exception for 45, 45Y, 48 and 48E (maximum net output under 1 MW AC by na

Parameter	Type	Required	Notes
credit	string	yes	The Code section claimed: 48 (energy credit), 48E (clean electricity investment credit), 45, 45Y, 45Q, 45V, 45Z, 45U, 45L, 179D, 30C or 48C.

The participation requirement (26 CFR 1.45-8(d)): a taxpayer, contractor or subcontractor that employs four or more individuals to perform construction, alteration or repair work on the facility, counted over the whole construction (not at one time), must employ at least one qualified apprentice there. Give the people one employer used on this facility with their roles; the tool says who counts to

Parameter	Type	Required	Notes
employer	string	no	The company (taxpayer, contractor or subcontractor) these people work for.
people	array	yes	Everyone this employer used on the facility over the whole construction, one entry each.

The apprenticeship labor-hours requirement for one facility (26 CFR 1.45-8(b)): qualified apprentices must perform the applicable percentage (10% if construction began before 2023, 12.5% in 2023, 15% from 2024) of total labor hours, counting every contractor and subcontractor, after excluding hours of foremen, superintendents, owners and executive/administrative/professional staff, and counting ap

Parameter	Type	Required	Notes
construction_began	string	yes	When construction began (YYYY-MM-DD or a year): sets the percentage.

good_faith_hours	number	no	Apprentice hours covered by denied or unanswered good-faith requests (1.45-8(f)(1)); they count as apprentice hours.
intentional_disregard	boolean	no	true if the failure was knowing or willful (the IRS decides); the rate becomes $500 an hour.
participation_failures	array	no	Employers with four or more individuals on the facility and no qualified apprentice (each adds a participation shortfall).

The ratio requirement (26 CFR 1.45-8(c)): on each day, for one employer and one occupation on the job site, the number of apprentices may not exceed what the registered program’s apprentice-to-journeyworker ratio allows for the journeyworkers present (or the ratio for the facility’s area). Give the program ratio and, for each day, the headcounts of journeyworkers and apprentices on site (the contr

Parameter	Type	Required	Notes
ratio_apprentices	integer	no	Apprentices side of the program ratio (default 1).

workers	integer	no	How many laborers or mechanics were paid this way (the penalty is per worker).
intentional_disregard	boolean	no	true if the failure was knowing or willful.
qualifying_project_labor_agreement	boolean	no	true if the work is under a pre-hire collective bargaining agreement for this project that meets 1.45-7(c)(6)(ii) and back pay is made before the credit is claimed (no penalty).
wages_due_date	string	no	When the wages were due (YYYY-MM-DD): the server looks up that quarter’s Federal short-term rate (table through 2026-10-16) to show the interest rate.
federal_short_term_rate_pct	number	no	Or give the Federal short-term rate (IRC 6621(b)) for the period yourself, in percent; the interest rate is that + 6 points.

year_wages_paid	number	no	What the worker was actually paid for that year on the facility (defaults to the year’s required wages less the shortfall entered).

Judges a request for apprentices under the Good Faith Effort Exception (26 CFR 1.45-8(f)(1)): a written request (electronic or registered mail) to a registered apprenticeship program covering the facility’s area and occupation, sent at least 45 days before the apprentices are needed (14 days for a later request to the same program), with the dates, occupation, location, number, expected hours, con

needed_from_date	string	no	When the apprentices were asked to start (YYYY-MM-DD): coverage runs from here.
needed_through_date	string	no	The last day of the employment period requested (YYYY-MM-DD), if the request named one.
later_request_to_same_program	boolean	no	true if this is a later request to a program already asked once (14-day lead time instead of 45).

Graded from the tools this server lists, not from its source code.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.

What the scan could actually read

A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph

The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
