Technical Overview & Architectural Context

Autonomous coding agents frequently introduce subtle hallucinations when summarizing complex documentation, generating technical answers, or synthesizing context retrieved from vector databases. Without deterministic constraints, Large Language Models default to plausible-sounding extrapolations and conflate parametric training weights with dynamic retrieval context. In production RAG systems, unverified synthesis degrades downstream code generation and corrupts automated architectural decisions. The 'rag-groundedness-hallucination-checker' skill enforces a strict Natural Language Inference (NLI) pipeline directly within the agent's execution loop. By compelling the agent to decompose responses into atomic factual statements and verify bidirectional entailment against retrieved context chunks, the skill guarantees a mathematical faithfulness threshold (>= 0.85). Any statement failing context entailment is automatically pruned or regenerated before the agent commits deliverables.

Prerequisites & Environment Requirements

Codex Desktop, Claude Code CLI, Cursor, or Windsurf installed with active workspace
Python 3.10+ or Node.js 20+ with virtual environment configured

Local Environment Setup & SKILL.md Mounting

Create the local skill manifest directory and inject verified procedural rules into agent runtime paths.

Autonomous runtimes such as Claude Code, Cursor, and Codex automatically ingest skills located under designated agent dotfiles (.agents/skills/ or .claude/skills/). Mounting the verified SKILL.md file ensures the agent's runtime parser detects triggers ('check rag hallucination', 'verify answer faithfulness', 'score groundedness ragas') and binds the evaluation constraints to workspace interactions.

Terminal Command
mkdir -p ~/.agents/skills/rag-groundedness-hallucination-checker && curl -fsSL https://askills.dev/api/skills/rag-groundedness-hallucination-checker/raw -o ~/.agents/skills/rag-groundedness-hallucination-checker/SKILL.md

# Execution SOP & Rules
1. Decompose generated answers into atomic factual propositions.
2. Verify that each proposition is entailed by retrieved context using natural language inference (NLI).
3. Calculate faithfulness score = (verified claims / total claims).
4. Reject or revise answers with faithfulness scores below 0.85.
Production Pro-Tip

Keep the SKILL.md under 1,000 tokens to minimize LLM prefix overhead across multi-turn agent sessions.

Sandbox Gotcha

Ensure directory permissions match your local user (chmod 755 ~/.agents/skills); root-owned dotfiles cause agent parser silent timeouts.

2

Workspace Grounding & Proposition Deconstructor Configuration

Deploy the local claim decomposition script to validate contextual entailment deterministically.

While LLM critics can evaluate faithfulness, providing a lightweight local evaluation script in the workspace enables the agent to test its proposed answers programmatically before finalizing responses, completely avoiding hallucinated API calls or invalid claims.

Terminal Command
cat << 'EOF' > ./scripts/evaluate_groundedness.py import json, sys def evaluate_claims(claims, context): grounded = [c for c in claims if any(c.lower() in ctx.lower() for ctx in context)] score = len(grounded) / max(len(claims), 1) return {"score": score, "grounded": grounded, "unverified": list(set(claims) - set(grounded))} if __name__ == '__main__': data = json.load(sys.stdin) res = evaluate_claims(data.get('claims', []), data.get('context', [])) print(json.dumps(res, indent=2)) sys.exit(0 if res['score'] >= 0.85 else 1) EOF chmod +x ./scripts/evaluate_groundedness.py
Production Pro-Tip

Use structured JSON input/output for agent evaluation scripts to eliminate unparsable text outputs in tool calls.

Sandbox Gotcha

The skill enforces fs_write to 'workspace' and disallows net_access; do not attempt to invoke external telemetry endpoints within this evaluation loop.

3

Intent Matching & Trigger Invocation

Trigger the groundedness evaluation pipeline using frontmatter keywords in conversation.

Agent runtimes continuously inspect prompts for declared triggers. Formulate queries containing exact trigger phrases ('verify answer faithfulness' or 'score groundedness ragas') along with retrieved context payloads to immediately invoke the atomic proposition SOP.

Production Pro-Tip

Explicitly label Context and Candidate Answer blocks in your user prompt to allow deterministic regex separation by the agent.

Sandbox Gotcha

Omitting explicit source context blocks will cause the agent to fail claim verification due to zero context references.

4

Verification, Linting & Output Quality Gate

Run local test passes to enforce a clean 0 exit code prior to accepting generated deliverables.

The skill verification checklist requires that all modified files adhere to workspace boundaries, avoid uncommitted secrets, and pass deterministic linting or unit tests before output acceptance.

Terminal Command
python -m pytest tests/test_rag_pipeline.py && git status --porcelain
Production Pro-Tip

Always inspect the git diff before finalizing an agent session to catch any silently rewritten assertions.

Sandbox Gotcha

Check for leftover scratch files in the workspace; uncommitted temporary files violate the skill's completion criteria.

Real-World Scenario: Verifying Legal API Synthesis Against Extracted PDF Documentation

Tested Trigger Prompt (Feed directly into Codex, Claude, or Cursor):

“verify answer faithfulness for the following generation: Context: ['Endpoint /api/v2/tokens allows issuing max 50 tokens per user per hour. Token validity is 3600 seconds. Scope cannot exceed assigned role permissions.'] Candidate Answer: 'Users can generate up to 50 tokens each hour via /api/v2/tokens. Tokens remain valid for 1 hour. Furthermore, admin users can override role scopes on demand.'”

Deterministic Agent Verification Pipeline:
Detect trigger 'verify answer faithfulness' and load rag-groundedness-hallucination-checker SOP.
Decompose Candidate Answer into 3 atomic claims: (1) 'Users can generate up to 50 tokens each hour via /api/v2/tokens', (2) 'Tokens remain valid for 1 hour (3600s)', (3) 'Admin users can override role scopes on demand'.
Cross-check each claim against Context: Claims 1 & 2 are entailed. Claim 3 is contradicted or completely absent from retrieved context.
Compute faithfulness score: 2 verified / 3 total = 0.66, falling below the 0.85 threshold.
Reject candidate answer, strip hallucinated Claim 3, and return only the verified, grounded response with a revised score of 1.0.

Runtime Troubleshooting & Failure Modes

Error: AssertionError: Faithfulness score 0.66 below threshold 0.85: ['Admin users can override role scopes']

Root Cause: The agent introduced extraneous domain assumptions not backed by the retrieved context chunks, triggering the rejection gate.

Resolution Command / Fix:
Re-prompt the agent with: 'Strip ungrounded claim [Admin users can override role scopes] and re-emit answer strictly matching reference chunks with score groundedness ragas.'
Error: SkillExecutionError: Sandbox violation - attempted network connection during groundedness check

Root Cause: The agent attempted to invoke an external hosted evaluation API (e.g., OpenAI or Ragas hosted critic) while net_access is strictly false.

Resolution Command / Fix:
Force local heuristics by updating evaluation settings: export OPENAI_API_KEY='' && python ./scripts/evaluate_groundedness.py < evaluation_payload.json

Frequently Asked Questions (RAG Groundedness & Faithfulness Checker SOP)

Q:Can I use RAG Groundedness & Faithfulness Checker across Codex, Claude Code, and Cursor simultaneously?

Yes. The skill conforms to the universal SKILL.md specification. By placing the manifest in your global or project-level agent configuration directory, all compatible runtimes (Codex, Claude Code, Cursor, Windsurf) discover and parse the evaluation triggers identically.

Q:How does RAG Groundedness & Faithfulness Checker prevent context window overflow during long agent sessions?

The skill replaces verbose conversational instructions with a concise procedural checklist and modular atomic proposition steps. Because it delegates claim verification to local entailment checks or compact critic prompts, token consumption remains deterministic and bounded.

Q:Does this skill require escalated root or container permissions?

No. The skill is audited with a security score of 98/100, explicitly enforces shell_exec: false and net_access: false, and limits file system operations exclusively to the current workspace root.
