Usage Guidance
This skill appears to do what it claims: condense/trim large exec outputs. Before installing or enabling it as a plugin, (1) confirm which runtime you use (Node vs Deno) because examples and code use mixed globals and may need slight adjustments; (2) review the full mod.ts (the provided snippet was truncated) to ensure there are no hidden network calls or file writes; (3) remember that if you wire this into OpenClaw's exec hook it will receive the raw output of commands — avoid running commands that emit secrets (tokens, private files) or review policies about which outputs are routed to plugins; (4) if you plan to install the plugin, inspect the plugin manifest (openclaw.plugin.json) and any install scripts that would be executed on install/restart.
Capability Analysis
Type: OpenClaw Skill
Name: openclaw-exec-truncate
Version: 1.0.1
The 'exec-truncate' skill is a utility bundle designed to compress and truncate verbose shell command output (such as git diffs, logs, grep results, and build logs) to optimize AI context window usage. The code in mod.ts and filter-registry.ts consists of string manipulation and regex-based filtering logic aligned with the stated purpose. While it accesses process.env.HOME and process.cwd(), it does so solely to strip local path prefixes from output for better readability and privacy. No evidence of data exfiltration, malicious command injection, or prompt-injection attacks was found.
Capability Assessment
Purpose & Capability
The name/description match the code: truncation functions for git diff/log, grep, ls, and build output and a FilteredExecutor to wrap exec calls. Minor inconsistencies: examples show Deno.Command usage in SKILL.md while core code uses Node-style globals (process.cwd(), process.env.HOME), and README claims plugin wiring into OpenClaw hooks although the SKILL.md explicitly states this distribution is standalone. These are likely implementation/platform variations but worth confirming for your runtime environment.
Instruction Scope
SKILL.md limits runtime behavior to string-processing of command output and to wrapping exec functions; it does not instruct reading unrelated files, contacting external endpoints, or accessing unrelated credentials. The documented fail-safe returns raw output on errors. It does reference optional wrapper scripts and a hook integration, which are consistent with the skill's goal.
Install Mechanism
No install spec is declared (instruction-only), so nothing will be pulled or executed at install time by the registry. The package includes source files but no automated download/install steps in the metadata. This is low install risk; if you later install as an OpenClaw plugin, the plugin install path (not provided here) should be reviewed.
Credentials
The skill declares no required env vars or credentials. The code reads environment/system info (process.cwd(), process.env.HOME) to strip path prefixes, which is proportionate to the stated purpose but does mean the code accesses your working directory and home path at runtime. Also note: truncation runs on whatever exec output it is given, and that output may contain sensitive data (tokens, file contents) if commands produce them.
Persistence & Privilege
Skill metadata does not request always:true and is user-invocable only. The provided code is a library-style utility that does not modify other skills or system-wide settings. If installed as a plugin into OpenClaw, it may be wired to a tool_result_persist hook (per README) and thus will see all exec outputs that the platform routes to that hook — this is expected for the stated purpose but increases the visibility of command outputs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install openclaw-exec-truncate - After installation, invoke the skill by name or use
/openclaw-exec-truncate - Provide required inputs per the skill's parameter spec and get structured output
