Prompt Compression

PassAudited by VirusTotal on May 12, 2026.

Overview

Type: OpenClaw Skill Name: prompt-compression Version: 1.0.1 The skill bundle's documentation and configuration files describe a local prompt compression tool designed to reduce token costs. SKILL.md contains no prompt injection attempts, and assets/trinity-compress.config.json defines text transformations solely for shortening prompts, not for injecting malicious commands or altering agent behavior. README.md and UPLOAD_CHECKLIST.md consistently refer to local script execution and demonstrate developer awareness of security best practices, such as scanning for banned terms and excluding sensitive files from the final package. No evidence of data exfiltration, remote execution, or other malicious intent is present in the provided files.

Findings (0)

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.

What this means

Compressed wording could unintentionally change how agents or skills behave across a repository.

Why it was flagged

The default target list includes broad agent, skill, and system-prompt files, so one run can change multiple files that affect future agent behavior.

Skill content
"targets": [".ai-workflow/skills/**/SKILL.md", "skills/**/SKILL.md", "scripts/ralph/CLAUDE.md", "claude.md", "openai.md", ".cursorrules", "system_prompt.md"]
Recommendation

Review and narrow the target list before running, inspect diffs afterward, and use the undo path if behavior changes unexpectedly.

What this means

Important instructions may become less clear or slightly change meaning after automated compression.

Why it was flagged

Balanced mode applies rule-based instruction compression, including deleting some instruction-introducing phrases; this is central to the purpose but can affect clarity if applied to safety- or approval-related prompts.

Skill content
"balanced": ["remove_filler", "fix_whitespace", "deduplicate", "compress_instructions", "shorten_examples"], ... "You are required to": ""
Recommendation

Avoid applying this blindly to security-critical prompts; review diffs before committing or using compressed prompts in production loops.

What this means

The documented install commands may fail, and any separately obtained installer script would not be covered by this review.

Why it was flagged

The README instructs users to run installer scripts, but the supplied manifest contains no scripts directory or installer files, so those runnable files were not available for review.

Skill content
powershell -NoProfile -ExecutionPolicy Bypass -File skills/trinity-compress/scripts/install.ps1 -RepoPath .
Recommendation

Use only reviewed files from the package, verify any installer script before running it, or wait for a package that includes the referenced scripts.

What this means

Old prompt content could remain in the repository as backup files and might be accidentally shared if not ignored.

Why it was flagged

Backup files intentionally persist copies of prompt/instruction files, which may include private project context or sensitive agent instructions.

Skill content
Creates **.bak** backups and supports instant undo.
Recommendation

Keep *.bak files ignored, avoid placing secrets in prompt files, and clean backups when they are no longer needed.
