Add /ultraresearch-local for structured research combining local codebase analysis with external knowledge via parallel agent swarms. Produces research briefs with triangulation, confidence ratings, and source quality assessment. New command: /ultraresearch-local with modes --quick, --local, --external, --fg. New agents: research-orchestrator (opus), docs-researcher, community-researcher, security-researcher, contrarian-researcher, gemini-bridge (all sonnet). New template: research-brief-template.md. Integration: --research flag in /ultraplan-local accepts pre-built research briefs (up to 3), enriches the interview and exploration phases. Planning orchestrator cross-references brief findings during synthesis. Design principle: Context Engineering — right information to right agent at right time. Research briefs are structured artifacts in the pipeline: ultraresearch → brief → ultraplan --research → plan → ultraexecute. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

// bash-normalize.mjs — Normalize bash parameter expansion evasion techniques.
|
|
//
|
|
// Attackers can evade command-name matching by inserting shell metacharacters
|
|
// that are transparent to bash but break regex patterns.
|
|
//
|
|
// This module strips these constructs from command names so that downstream
|
|
// pattern matching sees the canonical form.
|
|
//
|
|
// Exported as a shared module — used by pre-bash-destructive.mjs and
|
|
// pre-install-supply-chain.mjs.
|
|

/**
|
|
* Normalize bash parameter expansion and quoting evasion in a command string.
|
|
*
|
|
* Strips:
|
|
* - Empty single quotes: '' (e.g., w''get -> wget)
|
|
* - Empty double quotes: "" (e.g., r""m -> rm)
|
|
* - Single-char parameter expansion: ${x} -> x (evasion: attacker sets x=x)
|
|
* - Multi-char parameter expansion: ${ANYTHING} -> '' (unknown value)
|
|
* - Backslash escapes between word chars, iteratively (c\u\r\l -> curl)
|
|
* - Backtick subshell with empty/whitespace content
|
|
*
|
|
* Does NOT strip:
|
|
* - Quotes around arguments (only targets empty quotes that split command names)
|
|
* - $VAR without braces (not an evasion pattern)
|
|
* - Backslashes before non-word chars (\n, \t, etc.)
|
|
*
|
|
* @param {string} cmd - Raw command string
|
|
* @returns {string} Normalized command string
