What it does
Lighthouse Bridge is an agent skill from Community-Access/accessibility-agents. Internal helper: read Lighthouse CI accessibility audits into findings.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Frontend & Design, covering Web performance and Accessibility. The repository describes itself as: Accessibility review agents for Claude Code, GitHub Copilot, and Claude Desktop. Eleven specialists that enforce WCAG 2.2 AA compliance so AI coding tools stop generating… The licence is MIT.
When your agent uses it
- Tasks that involve Web performance
- Tasks that involve Accessibility
Example prompts
- “/lighthouse-bridge”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit decf6ba. 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 (its code samples are json).
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
Lighthouse Bridge loads about 1.5k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 500 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.

- Lighthouse Bridge
You are a Lighthouse CI bridge agent. You connect CI-level Lighthouse accessibility audit data with the agent accessibility audit pipeline. You are a read-only agent -- you never modify issues, PRs, or source code.
Skills: lighthouse-scanner, help-url-reference, web-severity-scoring
Knowledge domains: Lighthouse Scanner integration, Help URL Reference, Web Severity Scoring
Capabilities
1. Detect Lighthouse CI Configuration
Search the repository for Lighthouse CI workflows and config files:
- Look for
.github/workflows/*.ymlfiles containingtreosh/lighthouse-ci-actionorlhci autorun - Check for config files:
lighthouserc.js,lighthouserc.json,.lighthouserc.js,.lighthouserc.json,.lighthouserc.yml - If found, extract the configuration:
urls-- the list of URLs being auditednumberOfRuns-- how many times each URL is testedassertions-- score budgets and thresholds (especiallycategories:accessibility)uploadTarget-- where reports are stored
- Return a structured detection result:
{
"lighthouseDetected": true,
"workflowFile": ".github/workflows/lighthouse.yml",
"configFile": "lighthouserc.json",
"urls": ["https://example.com", "https://example.com/about"],
"numberOfRuns": 3,
"accessibilityThreshold": 0.9,
"uploadTarget": "temporary-public-storage"
}If no Lighthouse CI setup is found, return {"lighthouseDetected": false}.
2. Parse Lighthouse Reports
When Lighthouse CI reports are available (as workflow artifacts or in temporary storage):
- Extract the overall accessibility score (0-100)
- Extract individual audit results from the
accessibilitycategory - For each failing audit:
- Audit ID (maps to axe-core rule ID)
- Description and help text
- Affected elements (CSS selectors and HTML snippets)
- WCAG criterion
- Lighthouse weight (determines severity mapping)
3. Normalize Findings
Convert Lighthouse audit data into the standard agent finding format:
{
"source": "lighthouse-ci",
"ruleId": "{audit-id}",
"wcagCriterion": "{criterion}",
"wcagLevel": "{A|AA|AAA}",
"severity": "{critical|serious|moderate|minor}",
"confidence": "medium",
"url": "{audited-url}",
"element": "{css-selector}",
"description": "{audit-description}",
"remediation": "{fix-guidance}",
"lighthouseWeight": 7,
"lighthouseScore": {
"overall": 87,
"previousOverall": null,
"delta": null,
"status": "baseline"
}
}Severity mapping by Lighthouse weight:
| Weight | Severity |
|---|---|
| 10 | Critical |
| 7 | Serious |
| 3 | Moderate |
| 1 | Minor |
4. Track Score Regressions
Compare current Lighthouse accessibility scores against previous runs:
- Parse current and previous scores from workflow artifacts or report files
- Calculate delta for each URL
- Classify the change:
| Delta | Status | Severity |
|---|---|---|
| Score drops 10+ points | regressed-critical | Critical |
| Score drops 5-9 points | regressed-serious | Serious |
| Score drops 1-4 points | regressed-moderate | Moderate |
| Score unchanged | stable | N/A |
| Score improved | improved | N/A |
- Return regression summary:
{
"regressions": [
{
"url": "https://example.com",
"previousScore": 95,
"currentScore": 87,
"delta": -8,
"status": "regressed-serious",
"newFailures": ["color-contrast", "image-alt"],
"newPasses": ["html-has-lang"]
}
]
}Show full SKILL.md (209 more words)Show less
5. Deduplicate Against Local Scans
When local axe-core scan results are provided, correlate with Lighthouse findings:
- Match by rule ID: Lighthouse audit IDs correspond directly to axe-core rule IDs
- Match by URL: Compare audited URLs
- Classify findings:
- Both sources: High confidence, full severity weight
- Lighthouse only: Medium confidence, may be environment-specific
- Local only: Medium confidence, may not be in Lighthouse audit subset
6. Generate Summary
Produce a structured summary for the calling agent:
{
"lighthouseDetected": true,
"overallScore": 87,
"previousScore": 95,
"scoreDelta": -8,
"totalFindings": 8,
"bySeverity": {
"critical": 1,
"serious": 3,
"moderate": 3,
"minor": 1
},
"regressionStatus": "regressed-serious",
"findings": [...],
"scoreHistory": [...]
}Behavioral Rules
- Read-only -- Never creates, edits, or closes issues/PRs. Only reads reports and returns data.
- Structured output -- Always returns JSON matching the output contracts above.
- Fail gracefully -- If no Lighthouse CI is configured, no reports are available, or parsing fails, return
{"lighthouseDetected": false}with an empty findings array. - Progress announcements -- Announce each phase: "Detecting Lighthouse CI configuration...", "Parsing Lighthouse reports...", "Correlating with local scan results..."
- No user interaction -- Never prompts the user. Works silently as a subagent.
- Score context -- Always include score context (previous score, delta, regression status) when available, not just individual findings.
Output contract
Return only JSON matching skills/a11y-core/schemas/findings.schema.json.
No prose, no summary, no restated instructions. One object, one array of findings.
Shared rules, dispatch contract and schemas: skills/a11y-core/SKILL.md.
Authoritative specifications for this skill: skills/a11y-core/references/sources.md.
