What it does
Pagespeed Enhancer is an agent skill from sickn33/agentic-awesome-skills. Scan, audit, and fix web performance issues across all four Lighthouse/PageSpeed Insights pillars — Performance, Accessibility, Best Practices, and SEO — in structured batches.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/detailed-guide.md`).
It sits in Frontend & Design, covering Web performance. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Web performance
Example prompts
- “/pagespeed-enhancer”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Parses the score summary table — identifies LCP as critical bottleneck
- Runs Batch A scan — finds lazy-loaded hero image and render-blocking CSS
- Outputs risk report: F1.1 (CSS @import → link) ranked P1, F1.5 (LCP image eager) ranked P1
- Applies Fix Batch 1, verifies with re-test
What it can do on your machine
Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pagespeed Enhancer loads about 716 tokens when it runs, and up to ~5.9k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 371 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PageSpeed Enhancer Skill
A structured, batch-wise audit-and-fix workflow for all four Lighthouse pillars. Always follow the batch flow in order. Never jump straight to fixes without completing the scan and risk assessment phases.
Detailed Guide
Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
When to Use This Skill
- User pastes a PageSpeed Insights report or mentions Lighthouse scores
- User asks to improve Core Web Vitals (LCP, FCP, CLS, TBT, SI)
- User needs help with render-blocking resources, unused JavaScript, image optimisation, security headers, ARIA compliance, or SEO meta-tag fixes
- User asks "why is my LCP slow", "fix accessibility issues", "improve my SEO score", or "my site scores 80 on performance"
- Any mention of PageSpeed, Lighthouse, Web Vitals, or site speed
Examples
Example 1: User pastes a PageSpeed report
User: "My site scores 65 on Performance. LCP is 4.2s."
Agent:
- Parses the score summary table — identifies LCP as critical bottleneck
- Runs Batch A scan — finds lazy-loaded hero image and render-blocking CSS
- Outputs risk report: F1.1 (CSS @import → link) ranked P1, F1.5 (LCP image eager) ranked P1
- Applies Fix Batch 1, verifies with re-test
Show full SKILL.md (155 more words)Show less
Example 2: User asks about slow LCP
User: "Why is my LCP slow?"
Agent:
- Asks for a PageSpeed report URL or pasted results
- Runs LCP-specific audit from Batch A — checks TTFB, element render delay, lazy loading
- Identifies the LCP element, its current loading strategy, and the critical path chain
- Recommends targeted fix (preload, eager loading, or server response time improvement)
Limitations
- Does not run actual Lighthouse or PageSpeed tests — the user must provide the report or URL
- Security header recommendations assume the user controls the deployment platform (Netlify, Vercel, etc.)
- Fixes are general patterns; exact file paths and config syntax may vary by project setup
- Does not cover server-level optimisations (CDN config, PHP opcode caching, database queries, etc.)
- Image conversion commands assume the user has the required tools installed (cwebp, sharp, Pillow)
- CSP guidance uses a report-only iterative approach — the final policy must be tuned to each project's actual resource origins
