aki2022 Bundle Origin Permission AuditAudit and safely settle elevated access granted during the current or resumed session. Use when a task granted IAM roles, API scopes, bucket bindings, or other temporary access and the session is closing, or when the caller explicitly asks to audit or revoke session-granted permissions. Classify grants as temporary or standing, revoke temporary grants, verify the removal, and report the result; do not audit pre-existing access by guesswork.

rooseveltadvisors-claude-agent-stack Bundle CodereviewCode review and anti-pattern detection. USE WHEN user says review code, audit code, check for anti-patterns, code quality check, OR find bugs. Scans for security issues, anti-patterns, and project-specific violations.

trilwu Bundle Testing ApisTest REST and GraphQL APIs for authentication bypasses, authorization flaws, IDOR, mass assignment, injection attacks, and rate limiting issues. Use when pentesting APIs or testing microservices security.
-
trilwu Skill Authoring Security SkillsWrite a new SecSkills skill end to end — choosing the plugin bucket and skill tier, writing a description that triggers correctly without stealing traffic from siblings, the required sections, registering the skill in ttp-index.json, adding routing eval cases including negative traps, and running the three validators. Use when adding a skill to this repo, splitting or merging existing skills, fixing a skill that triggers on the wrong requests, or when a new skill fails validate.py, sync_attack.py, or run_evals.py.
-
trilwu Skill Diffing Binary PatchesLocate the vulnerability a security patch fixes by diffing the pre- and post-patch binaries — using BinDiff, Diaphora, or ghidriff to find the changed functions, reading the added checks to recover the bug class, and reasoning back to a reachable pre-patch trigger for 1-day analysis. Use when comparing two versions of a DLL/ELF, extracting a Microsoft patch from an MSU/MSP for delta comparison, or turning a vague advisory into the exact code that changed.
-
trilwu Skill Reviewing Code ChangesPerform a security review of a diff, branch, or pull request — assessing what the change introduces, weakens, or exposes, with a triage-first workflow and false-positive discipline. Use when asked to security review a PR or branch, check a diff before merge or commit, or assess whether a change is safe to ship.
-
trilwu Skill Analyzing ShellcodeAnalyze raw shellcode and position-independent code — extracting the bytes, guessing architecture, disassembling at the right base, decoding self-decoder stubs, resolving hashed Windows APIs, emulating to the decoded stage, and pulling C2 and stage IOCs. Use when handed a raw blob of position-independent code, an extracted payload with no PE/ELF header, shellcode lifted from an exploit or a macro/loader, a `\x`-escaped or base64 buffer, a suspected Cobalt Strike or Metasploit stager, or an egg-hunter.

Use when analyzing a .app bundle or Mach-O on macOS, checking entitlements and notarization, hunting a dylib-hijack or XPC privilege bug, or reasoning about Gatekeeper and quarantine.
-
trilwu Skill Testing Thick ClientsSecurity-test desktop thick-client applications (.NET/WPF, Java, Electron, native Win32) against their local and network attack surface — proxying non-HTTP traffic, extracting secrets and DB connection strings from config/registry/memory, bypassing client-side trust controls, and reviewing update channels and DLL search order. Use when assessing an installed desktop app that talks to a backend, when Burp sees no traffic from a fat client, or when a two-tier app connects straight to a database.
-
trilwu Skill Mapping Attack TechniquesNavigate security work by MITRE ATT&CK tactic and technique — resolve a technique ID or name to the right skill, map a threat intel report or adversary emulation plan to procedures, and run the purple-team loop from technique to detection to validation. Use when a request names an ATT&CK ID like T1003.001, a tactic like lateral movement, an APT group or intel report, or when planning coverage against the matrix.
