Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Stops a hijacked or prompt-injected AI agent from running destructive commands, leaking secrets, or poisoning memory it writes through ShieldCortex.

Trusted task: let it work. Hijack: a plain-English card. Catastrophe: a hard stop.

What a catch looks like

shieldcortex scan "ignore previous instructions"

ShieldCortex Scan Result
──────────────────────────────────────────────────
Result:      QUARANTINE
Source:      cli:shieldcortex-scan (attested)
Provenance:  cli (trusted, L2 not applied)
Trust:       0.90
Sensitivity: PUBLIC
Anomaly:     0.00
Reason:      Quarantined: Instruction injection detected (confidence: 0.8)
Threats:     instruction_injection
Patterns:    hidden_instruction

That string was caught and quarantined. Nothing was stored as a memory, and the exit code is non-zero so a script or CI job can act on it. How scan results work.

What you get

Memory firewall. ShieldCortex does not replace OpenClaw, Hermes, or Claude memory. Writes that go through it are scanned before they stick. Recognised injection and leaked credentials are quarantined or blocked.
Tool gate. On Claude Code, OpenClaw, and Hermes, once Action Guard is on, a trusted task runs, a suspicious call gets a plain-English card, and a catastrophic command is a hard stop.
*Inspect.

Exposed tools (45)

32 read · 8 write · 5 destructive. Blast radius: 5 tools can delete or overwrite — an agent that can be talked into calling a tool can be talked into calling this one.

Tool	Risk	Description
`TEXT`	read	TEXT
`add`	write	Adds two numbers together and returns the sum.
`audit_query`	read	Query defence audit logs for forensic analysis
`consolidate`	write	Run memory consolidation (like brain sleep). Promotes STM to LTM, decays old memories. Use dryRun to preview.
`defence_stats`	read	Get defence system statistics
`detect_contradictions`	read	Scan memories for potential contradictions. Finds memories that may contain conflicting information about the same topic, such as: - Different solutions to the same problem - Conflicting recommendations (use X vs don
`end_session`	write	End session and trigger consolidation.
`export_memories`	read	Export memories as JSON for backup.
`forget`	destructive	Delete memories. Use dryRun: true to preview, confirm: true for bulk.
`get_context`	read	Get relevant context from memory. THE KEY TOOL for maintaining context. Use at session start, after compaction, when switching tasks, or to recall project info. Returns: architecture decisions, patterns, pending items, recent activity.
`get_memory`	read	Get a specific memory by ID.
`get_project`	read	Show current project scope and detection info.
`get_related`	read	Get memories related to a specific memory. Shows connections and relationships.
`graph_entities`	read	List known entities in the knowledge graph, optionally filtered by type.
`graph_explain`	read	Explain the relationship between two entities by finding paths connecting them in the knowledge graph.
`graph_query`	read	Traverse the knowledge graph from an entity. Returns each reachable entity once, at its shallowest depth, with the edge that first reached it (BFS spanning tree — parallel edges between the same pair are not enumerated).
`import_memories`	write	Import memories from JSON.
`iron_dome_activate`	read	Activate Iron Dome with a profile. Profiles: school (GDPR strict), enterprise (financial protection), personal (lighter touch), paranoid (everything requires approval).
`iron_dome_check`	read	Check if an action is allowed (gateway + action gate). Use this before performing external actions like sending emails or deleting files.
`iron_dome_emergency_stop`	destructive	Emergency kill switch — immediately locks down ALL agent operations. Use when you detect suspicious activity. Reversible via iron_dome_resume.
`iron_dome_resume`	destructive	Resume agent operations after kill switch investigation. Only use after confirming the threat has been addressed.
`iron_dome_scan`	read	Scan text for prompt injection patterns. Returns detections with category, severity, and matched text.
`iron_dome_status`	destructive	Check if Iron Dome is active and show kill switch state. Shows config summary including profile, trusted channels, and approval rules.
`link_memories`	write	Create a relationship link between two memories.
`lookup`	read	Look up a record.
`memory_stats`	read	Get memory statistics.
`override_morphology_active`	read	Override intent in the active voice, any inflection (e.g.
`override_morphology_passive`	read	Override intent in the passive voice (e.g.
`override_morphology_stop_following`	write	Negated-compliance framing (e.g.
`quarantine_review`	read	Review and manage quarantined memories
`recall`	read	Search and retrieve memories. Use this to: - Find relevant context (
`remember`	read	Store information in memory for later recall. Use this to remember: - Architecture decisions (

`scan_skill`	read	Scan an agent instruction file (skill, hook, rules) for threats. Supports Claude Code (SKILL.md), OpenClaw (HOOK.md, handler.js), Cursor (.cursorrules), Windsurf (.windsurfrules), Cline (.clinerules), GitHub Copilot, Aider, Continue.
`scan_tool_response`	read	Scan a tool response for injection attacks and credential leaks. Use this to verify responses from external MCP servers before trusting their content. Runs injection detection (40+ patterns) and credential leak scanning (25+ providers).
`set_project`	write	Switch active project context. Use
`shieldcortex-intercept-tool`	read	Active threat gating on tool calls
