Promql Cli

• Outcome: Review
• Latest audit: Sep 14, 2026 · 11:51 PM UTC
• Version: 1.1.3

Overview

The skill is mostly purpose-aligned for Prometheus querying, but its install guidance recommends unverified third-party binaries with system-wide placement.

Review the installation steps before installing. Prefer a user-local install path, pin an immutable version, and verify checksums or signatures for promql-cli before executing it, especially if it will access Prometheus tokens, password files, TLS keys, or production monitoring data. Do not paste monitoring credentials into the agent chat; configure them manually in local files with restricted permissions.

A.I.G

Vulnerability Patterns

• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

' "$tmpdir/promql.tar.gz" | sha256sum --check - ``` On macOS, use `shasum -a 256` where appropriate. Prefer a cryptographic release signature or provenance attestation when upstream provides one. 3. Stop installation on download or verification failure. Use strict shell handling such as `set -euo pipefail` in any installation script. 4. Inspect archive contents before extraction and reject absolute paths, parent-directory traversal entries, unexpected files, links, or device nodes: ```bash tar tzf "$tmpdir/promql.tar.gz" ``` 5. Extract into the isolated temporary directory, confirm that the expected file is a regular executable, and only then install it. 6. Prefer a user-owned destination such as `~/.local/bin` or `$(go env GOPATH)/bin`. Only offer `/usr/local/bin` as an explicit optional system-wide installation requiring informed user approval. 7. Replace mutable references with immutable reviewed versions: - Use a specific tagged Go module version rather than `@latest`. - Check out and verify a specific tag or commit when building from source. - Ensure installation metadata and documentation reference the same reviewed release. 8. Document the upstream trust boundary and instruct users to compare checksums against a separately authenticated source before executing the binary. ]]>

Vulnerability Patterns

• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Rogue Agent: Self-Modification, Session Persistence
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The manifest description says to apply the skill when 'troubleshooting performance issues on a software having observability' or 'analyzing time series data,' which are very broad conditions without clear boundaries or exclusion cases. In a user-invocable skill description, this can overlap with many ordinary debugging or analysis requests and may cause unintended invocation.

Content

No source excerpt is available for this finding.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 60% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

If any of these appear, **do not create config files on behalf of the user** — config files may contain credentials (tokens, passwords) that must never pass through an LLM. Instead, guide the user to set it up themselves:

> "Please create `~/.promql-cli.yaml` manually with your Prometheus host (and credentials if needed). See `references/installation.md` for the exact format. Let me know once it's ready."

3. **Filter early with label matchers in the innermost selector** — Prometheus evaluates selectors before functions, so filtering late means scanning all time series. Early filters reduce data scanned and query latency.
4. **For histograms, keep `le` in the `by` clause** before `histogram_quantile()` — the function needs all `le` buckets to interpolate percentiles; dropping `le` early produces `NaN` or wrong results.
5. **Prefer `--output graph` for range queries** — ASCII sparklines convey trend direction (rising, falling, spiking) in a compact format that LLMs parse well; raw timestamp tables require mental modeling.
6. **Store credentials in `~/.promql-cli.yaml` and `~/.promql_token`, chmod 600** — passing tokens as CLI args exposes them in shell history and process listings.

Finding

This JSON file is a manifest-like file, so vague trigger review applies. The prompt text "Show me the current request count for my web API using promql-cli" models a broad natural-language invocation pattern rather than a narrowly defined trigger list, and it does not provide exclusion conditions or constraints to reduce accidental overlap with ordinary requests for help.
