## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.2.21
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

LPM treats this as warn-only first-party agent extension lifecycle risk. Runtime Slack session setup can create a workspace Cursor hook and carrier script to deliver queued Slack follow-ups at tool boundaries. This is a guarded, first-party agent integration capability; no confirmed attack surface was established.

## Security analysis

### Published attack-surface review

- **Summary:** Runtime Slack session setup can create a workspace Cursor hook and carrier script to deliver queued Slack follow-ups at tool boundaries. This is a guarded, first-party agent integration capability; no confirmed attack surface was established.

- **Trigger:** A local Slack session with a nonempty continuation key, a non-borrowed workspace, and steering disabled.

- **Impact:** The hook can run at tool boundaries and supply queued Slack follow-up context to the agent.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T05:57:04.162Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The package writes carrier state and a script under .agent-serve, then adds the script command to preToolUse and postToolUse entries in .cursor/hooks.json.

- **Rationale:** The package has a postinstall skill installer and a runtime Slack feature that adds Cursor hooks. The hook behavior is gated to first-party Slack session handling, so this warrants a warning for agent extension lifecycle risk rather than a malicious verdict.

- **Files touched:** .agent-serve/slack-nudge-root, .agent-serve/slack-nudge-continuation, .agent-serve/slack-nudge-carrier.mjs, .cursor/hooks.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package postinstall invokes a bundled Cursor skills installer., Session setup installs the Slack nudge carrier only for Slack sessions with a continuation key, and skips borrowed workspaces and steering-enabled runs., The carrier writes files under the workspace’s .agent-serve directory and adds its command to Cursor preToolUse and postToolUse hooks, preserving other hooks., Slack follow-ups are queued for the carrier when steering is disabled.

- **Evidence against:** The hook setup is gated to a first-party Slack feature and local workspace conditions; it is not an npm install mutation of the consumer’s agent configuration., The postinstall installer is best-effort and exits when its bundled entrypoint is missing.

## Affected versions and remediation

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@cursor/july@0.2.21/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node -e "try{const p='./scripts/install-cursor-skills.mjs';if(require('fs').existsSync(p))require('child_process').execFileSync(process.execPath,[p],{stdio:'inherit'})}catch{}"
```

### 2. Critical: Red Install Lifecycle Script
- **Category:** Manifest
- **Confidence:** 95.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@cursor/july@0.2.21/package.json>)

Install-time lifecycle script matches a deterministic static-gate block pattern.

Public source snippet (untrusted):

```json
scripts.postinstall = node -e "try{const p='./scripts/install-cursor-skills.mjs';if(require('fs').existsSync(p))require('child_process').execFileSync(process.execPath,[p],{stdio:'inherit'})}catch{}"
```

### 3. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 4. Low: Eval
- **Category:** Source
- **Confidence:** 45.0%

Package source references a known benign dynamic code generation pattern.

### 5. Medium: Dynamic Require
- **Category:** Source
- **Confidence:** 75.0%
- **Path:** dist/internal/authored-loaders.js
- **Public source:** [View source](<https://unpkg.com/@cursor/july@0.2.21/dist/internal/authored-loaders.js>)

Package source references dynamic require/import behavior.

Public source snippet (untrusted):

```javascript
L37: *
L38: * Node caches `import()` by URL for the life of the process, so a long-lived
L39: * `agent-sdk dev` would otherwise keep serving the first load of eval files
```

### 6. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 7. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

### 9. High: Copied Package Dependency Bridge
- **Category:** Source
- **Confidence:** 83.0%
- **Path:** dist/channels/slack/slack-channel.js
- **Public source:** [View source](<https://unpkg.com/@cursor/july@0.2.21/dist/channels/slack/slack-channel.js>)

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.

Public source snippet (untrusted):

```javascript
package = @cursor/july; repositoryIdentity = cursor; dependency = @slack/web-api
L194: }
L195: const { WebClient } = await import("@slack/web-api");
L196: allowlist.applyResolvedNames(await resolveChannelNames(new WebClient(botToken), names, getLog()));
```

### 10. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 11. Low: Telemetry
- **Category:** Supply Chain
- **Confidence:** 70.0%

Package source references telemetry or analytics APIs.

### 12. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 13. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 14. Low: No License
- **Category:** Manifest
- **Confidence:** 80.0%

Package manifest does not declare a clear license.

### 15. High: Semantic Analysis Limited
- **Category:** Scanner Coverage
- **Confidence:** 100.0%
- **Path:** dist/channels.js
- **Public source:** [View source](<https://unpkg.com/@cursor/july@0.2.21/dist/channels.js>)

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

Public source snippet (untrusted):

```javascript
stage = ast_semantic_analysis; reason = ast_alias_growth_limit_exceeded; limitedFiles = 15
```
