Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-18 (score 65, +15)

- [security improvement] Malware scan: unverified → pass

### 2026-10-17 (score 50)

First indexed and scored.

## MCP tools (4)

### `codexguild_scan_skills` (~112 tokens)

Security-audit the skills installed on THIS machine (~/.claude/skills, Claude plugins, ~/.codex/skills, ~/.agents/skills, ~/.hermes/skills, project skills…). Detects pipe-to-shell, credential exfiltration, hidden unicode, prompt injection, agent-config tampering and safety bypasses. Runs locally — nothing is uploaded.

Input parameters:

- `paths` (array): Optional directories to scan instead of the defaults
- `verbose` (boolean): Include passed skills and all findings

### `codexguild_lint_instructions` (~101 tokens)

Lint the agent instruction files in this project (AGENTS.md, CLAUDE.md, GEMINI.md, .cursorrules…): size per session, missing build/test commands, README copy, generic advice, secrets, machine-specific paths, prompt-injection and other scanner findings. Runs locally — file contents are not uploaded.

Input parameters:

- `files` (array): Paths to lint instead of the instruction files found in the project root

### `codexguild_scan_workflows` (~119 tokens)

Security-review the GitHub Actions workflows in this project that run coding agents (claude-code-action, run-gemini-cli, codex, opencode, aider…): triggers outside contributors control (pull_request_target, issue_comment, issues) combined with secrets, issue/PR text interpolated into prompts or shells (prompt injection), unrestricted agent tools, broad permissions, unpinned agent actions. Runs locally — nothing is uploaded.

Input parameters:

- `files` (array): Workflow files to review instead of .github/workflows/*.yml

### `codexguild_scan_code` (~104 tokens)

Find deprecated and removed APIs in this project's code for the exact versions it runs (from the lockfiles): e.g. `app.mount` deprecated in hono 4.13, with the replacement and where it is used (file:line). Only package names and versions are sent to CodexGuild; the code is searched locally and never uploaded. codexguild_sync runs this automatically.

Input parameters:

- `cwd` (string): Project directory (defaults to the current directory)

### Is the CodexGuild MCP server still maintained?
