Agent reason: the procedures an agent follows (onboarding, reconciling a
month, closing a month, the CPA hand-off, the year's compliance, an audit)
should be one name away, written against this server's own tools, instead of
rebuilt from the handbook each session. The server now advertises the
prompts capability (also in the bridge's cold-start initialize, which uses
the same capabilities function) and serves prompts/list and prompts/get to a
token that may read: onboard, reconcile {account, month}, month_end_close
{month}, cpa_handoff {year}, annual_compliance {year}, audit {scope}. Each
text is a file in crates/ledger-mcp/prompts/ with the company's name and the
arguments filled in. migrate, process_inbox and receipts_from_email are not
built (D-46, D-28, D-17). audit points at books.verify, books.control_check
and the digest; P8 fills in its own tools.
An argument is one token (letters, digits, - _ . :, at most 40) of the shape
the prompt asks for (a month, a year, a word from a list), so what a caller
passes can never rewrite the text; an unknown prompt, a missing, extra or
malformed argument is refused. A test checks every prompt names only tools
that exist.
The five resource templates of plan 4.5 are advertised (resources/templates/
list): books://entries/{id}, books://attachments/{id}, books://journal/{seq},
books://reports/{kind}{?start,end,as_of} and
books://digest{?since,since_seq,as_of}; the reports now take their dates
from the query (they read only today's or the year to date before), and the
digest reads since_seq (what was posted since a journal line, backdated
entries included).
Tests: the_prompts_name_only_tools_that_exist,
an_argument_is_one_token_of_the_right_shape.
