awrshift Skill Memory AuditAudit MEMORY.md against the memory discipline — oversized sections, settled multi-session patterns that belong in knowledge/concepts/, stacked chronicle blocks, stale entries. Produces a move plan as a table for approval, then executes the approved moves atomically. Use when the SessionStart hook reports a tripped cap, when PreCompact blocks on an oversized cache, or when the user says "/memory-kit:memory-audit", "audit memory", "проверь память", "почисти память". Refuses only when no cap is tripped AND no settled-pattern candidate exists.

propstreet Bundle Pr Audit AnglesMulti-angle parallel audit of a large PR or branch before merge. Dispatches one capable subagent per angle (matched to the changed surface), each anchored to the repo's own conventions and producing a uniform Blockers / Important / New-concepts-verdict / Verified-clean report; the orchestrator verifies every candidate against current code and synthesizes one merge-readiness verdict. Use when a PR spans multiple subsystems, when you worry it introduces new concepts where patterns already exist, or when asked to "audit before merge", "review from every angle", "is this safe to merge".

-
argythana Bundle Code ReviewUse this skill when the user wants a production-grade review of Python code, a Python pull request, or a Python-focused diff. Check architecture, security, code quality, tests, documentation, deployment risk, and code-documentation consistency. Trigger on requests like "review this Python PR", "audit this diff", "check code quality", or "give me a fix plan". Do NOT use it for non-Python code review, writing new features, dependency-only changes, pytest-suite-specific audits where `pytest-suite-review` is a better fit, or iterative review-fix-rerun loops where `code-review-loop` is a better fit.
-
argythana Skill Code Review LoopUse this skill when the user wants an iterative `code-review` loop over Python changes: review a Python diff, PR, branch, or commit range with `code-review`, fix the actionable Critical, High, and Moderate findings, run the relevant checks and tests, and repeat until 5 consecutive clean PASS reviews, `insufficient evidence`, or max cycles. Trigger on "run code-review until clean", "keep reviewing and fixing this Python PR until it passes", or "fix the code-review findings and rerun review until acceptable". If the target repo, diff, branch, commit, or commit range is referenced but unavailable, ask after routing. Do NOT use for a single review-only pass; use `code-review`. Do NOT use for pytest-suite-specific audit loops; use `pytest-suite-review-loop`. Do NOT use for implementing a task against Acceptance Criteria; use `task-implementation-loop`. Do NOT use for non-Python code, dependency-only changes, or writing new features from scratch.
-
argythana Bundle Do Literature ReviewUse this skill when the user asks for a verifiable literature review or peer-reviewed citations for an ADR, design doc, paper, or technical decision, with prompts like "literature review on X", "find papers on X", "survey the literature on X", or "cite peer-reviewed sources for X". Enforce structural verification: every emitted citation needs metadata lookup, full-text retrieval, a supporting quote with locator, byte-for-byte author attribution, Negative Findings, and a self-audit table. Do NOT use it for single-URL summarization, drafting the surrounding ADR, casual citation pointers where verification is explicitly waived, fictional references, or unsourced factual questions.
-
manolakis Skill Security ReviewIdentify security weaknesses in code and dependencies using OWASP Top Ten as reference
-
hyhmrright Bundle Logic HealthSweep a directory, module, or full codebase for logic correctness and produce a scored health dashboard with systemic patterns. Trigger when the user requests a health view — "audit the whole codebase", "health check", "health overview", "logic health overview", "audit src/", "audit auth and payments modules", "where should I focus testing", "onboarding review", "logic overview before we ship", "give me a health overview of this module". SCOPE RULE: prefer multi-file; also trigger for a single module when the user explicitly uses "health check", "health overview", or "logic health" — a concrete failure uses logic-locate; two versions uses logic-diff; explaining a path uses logic-explain; "fix everything" uses logic-fix-all. Do NOT trigger for: style/architecture-only audits, security-only scans, performance-only audits.
