kb-web-severity-scoringReference data, not a reviewer. An agent skill from Community-Access/accessibility-agents.
Kb Web Severity Scoring is an agent skill from Community-Access/accessibility-agents. Reference data, not a reviewer. Compute web accessibility scores (0-100, A-F grades) with severity scoring, confidence levels, and remediation tracking across audits.
Its SKILL.md is about 2.1k 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 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.
Read from SKILL.md and the folder at commit decf6ba. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown, pseudocode and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Kb Web Severity Scoring loads about 2.1k tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 718 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.
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.
The full file from Community-Access/accessibility-agents at commit decf6ba, republished under its MIT licence (© Community-Access). 718 words, ~2,114 tokens.

Weights:
Critical (confirmed, all three sources): -18 points
Critical (high confidence, both sources): -15 points
Critical (high confidence, single source): -10 points
Critical (medium confidence): -7 points
Critical (low confidence): -3 points
Serious (high confidence): -7 points
Serious (medium confidence): -5 points
Serious (low confidence): -2 points
Moderate (high confidence): -3 points
Moderate (medium confidence): -2 points
Moderate (low confidence): -1 point
Minor: -1 point
Floor: 0 (minimum score)Use a profile to tune strictness by context while keeping comparable grade bands:
| Profile | Intended Use | Multiplier |
|---|---|---|
| balanced (default) | Standard product delivery | 1.0 |
| strict | Regulated/public-sector releases | 1.15 |
| advisory | Early design and prototyping | 0.8 |
Apply the profile multiplier to each final deduction after confidence handling.
page_score = 100
for each finding:
base = lookup(severity, confidence_level, source_count) // from table above
multiplier = 1.2 if confidence_level == "confirmed" else 1.0
deduction = base × multiplier
page_score = max(0, page_score - deduction)The values in the lookup table above are base deductions (pre-multiplier). "Confirmed" findings (validated by all three sources: axe-core + agent review + Playwright) apply an additional 1.2× multiplier.
Example: One Critical finding at confirmed confidence = 18 (base) × 1.2 = 21.6 points deducted → page score 78.
To reduce false-positive inflation and stabilize trends, apply a calibration coefficient by rule family:
calibrated_deduction = deduction × calibration_coefficient(rule_family)Recommended initial coefficients:
| Rule Family | Coefficient | Rationale |
|---|---|---|
| Keyboard/focus | 1.1 | High functional impact at runtime |
| Forms/labels/errors | 1.05 | High completion risk for core tasks |
| Semantics/structure | 1.0 | Baseline scoring |
| Link text/context | 0.9 | Higher context variance |
| Content quality (alt/link clarity) | 0.85 | Needs human review more often |
Update coefficients quarterly from confirmed outcomes. Avoid changing coefficients more than +/-0.1 per cycle.
Each score, with its grade and meaning.
| Score | Grade | Meaning |
|---|---|---|
| 90-100 | A | Excellent - minor or no issues, meets WCAG AA |
| 75-89 | B | Good - some issues, mostly meets WCAG AA |
| 50-74 | C | Needs Work - multiple issues, partial WCAG AA compliance |
| 25-49 | D | Poor - significant accessibility barriers |
| 0-24 | F | Failing - critical barriers, likely unusable with AT |
Each level, with weight and when to use.
| Level | Weight | When to Use |
|---|---|---|
| Confirmed | 120% | Validated by all three sources: axe-core + agent review + Playwright behavioral testing |
| High | 100% | Confirmed by axe-core + agent, or definitively structural (missing alt, no labels, no lang) |
| Medium | 70% | Found by one source, likely issue (heading edge cases, questionable ARIA, possible keyboard traps) |
| Low | 30% | Possible issue, needs human review (alt text quality, reading order, context-dependent link text) |
Issues found by both axe-core AND agent review are automatically upgraded to high confidence regardless of individual confidence ratings.
Issues found by all three sources (axe-core + agent review + Playwright behavioral testing) are upgraded to confirmed confidence with a 1.2x weight multiplier. This applies when:
When Playwright is not available, the maximum achievable confidence remains High (100%). The confirmed tier is additive — it never downgrades findings.
Track predicted confidence versus post-triage outcome and compute drift:
drift = abs(predicted_confidence_score - observed_confirmation_rate)Operational guideline:
