reviewing-security-prior-art-survey
reviewing-security-prior-art-survey
bm629 / agent-skills

Use when judging a finished security prior-art artifact — a threat-vocabulary map, a per-angle search output, an extract record, or the threat register — to decide whether the research craft is honest, complete against its own contracts, and proportionate. An acceptance gate, not authoring: it runs the producer's validator once, then judges what a validator cannot see — whether a coverage claim is provable, whether a source failure was typed or written as a zero, whether a bail was a confident relevance bail rather than a hedge, whether an evidence tier follows from evidence the record's own body agrees with, and whether a register names threats from a real vocabulary rather than coining them. Emits VERDICT: approve|revise with condition-named findings. Keywords: security prior art review, threat research review, coverage honesty, survey acceptance gate. Judges all three survey waves.

work-implement

Implement already-specified work in code, of four types: (1) technical tasks (TK-XXX) under a user story; (2) maintenance tasks (WI-XXX) without a story — bugs, refactoring, technical debt, dependencies, operations; (3) test cases (TC-XXX) — automate the tests already documented by test-define; (4) features (FT-XXX) — automate the TCs of their acceptance criteria. Select the type according to the referenced artifact. Only implement work in State: Ready; it also accepts a bounded correction mode, delegated by quality-check, on any artifact of the branch (US-XXX, WI-XXX, FT-XXX, TC-XXX on a test/ branch, or an artifact external to the plugin), to fix a failing check or test. Always activate when the user asks to "implement", "develop", "execute tasks", "code", "automate the tests", "implement the test cases", "work on the TK/WI/TC/FT", or variants implying writing code from an already-drafted specification.

Development47

Activate when the user asks to close, deliver, merge, integrate, finish, or submit the work of a story, a WI, a feature, or the current branch.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
