When to Use This Prompt

Determine when a data-driven lint rule audit is the right tool versus when simpler heuristics or human judgment suffice.

Platform teams accumulate lint rules over years. Some rules catch critical bugs before they reach production. Others generate noise, slow down CI pipelines, and train developers to ignore warnings. This prompt audits a single lint rule against its violation history, false positive rate, and fix rate to produce a data-driven keep, reconfigure, or remove recommendation. The primary job-to-be-done is replacing gut-feel rule curation with evidence-based decisions that improve developer experience without sacrificing safety. The ideal user is a platform engineer, DevSecOps lead, or engineering manager running a quarterly tooling retrospective or preparing for a lint configuration overhaul.

Use this prompt when you have aggregated rule statistics available: violation count over time, false positive rate (percentage of violations developers marked as invalid or suppressed with justification), and fix rate (percentage of violations that resulted in a code change within a defined window). The prompt requires these three data points as minimum inputs. If you lack historical data on false positive rates or fix rates, run the False Positive Detection and Suppression Justification Prompt first to build the evidence base from raw violation logs and suppression comments. Do not use this prompt for brand-new rules with fewer than 30 days of violation history—the sample size is too small for meaningful analysis. Do not use it for rules that are legally or contractually required; compliance-mandated rules are non-negotiable regardless of developer friction.

The prompt produces a structured recommendation with an effectiveness score, a decision category (keep, reconfigure, remove), and a justification grounded in the provided statistics. It also flags data-quality concerns such as insufficient sample size or contradictory signals. Wire the output into your lint config review process as one input among several: combine it with developer survey feedback, incident postmortems that reference specific rules, and your team's explicit quality policies. The prompt is a decision-support tool, not an automated rule removal engine. Always require human review before disabling or reconfiguring a rule that affects production CI gates.

PRACTICAL GUARDRAILS

Use Case Fit

Where the Linting Rule Effectiveness Audit Prompt delivers value and where it creates risk. Use these cards to decide if this prompt fits your current workflow before you invest in wiring it up.

01

Good Fit: Data-Rich Rule Evaluation

Use when: you have historical lint run data (violation counts, suppression rates, fix rates) across multiple commits or time windows. The prompt needs quantitative signals to produce a meaningful effectiveness score. Avoid when: you only have a single snapshot of lint output with no trend data.

02

Bad Fit: Greenfield Linter Adoption

Avoid when: you are introducing a linter to a codebase for the first time and have no historical violation data. The prompt cannot assess effectiveness without evidence of how rules behave in practice. Use instead: the Linting Baseline Generation Prompt to establish a starting point, then revisit this audit after several sprints.

03

Required Inputs: Structured Violation History

What you need: a dataset containing rule IDs, violation counts per time period, suppression or disable counts, and fix counts (or fix rate proxies). The prompt expects structured input, not raw linter stdout. Guardrail: pre-process raw linter output into a consistent schema before calling the prompt, or use the Multi-Linter Output Normalization Prompt as a preprocessing step.

04

Operational Risk: False Confidence in Scores

What to watch: the model may produce a plausible-looking effectiveness score even when input data is sparse, noisy, or biased by suppression patterns. A rule with many suppressions might look clean when it is actually being ignored. Guardrail: require the prompt to surface suppression rate as a separate signal and flag rules where suppression rate exceeds a configurable threshold.

05

Operational Risk: Recommendation Without Team Context

What to watch: the prompt may recommend removing a rule that has low fix rates but high security or compliance value. Effectiveness scores based only on fix rates miss the preventative value of rules that catch critical issues rarely. Guardrail: always include a rule category or criticality tag in the input schema, and add a constraint that security or compliance rules require explicit human review before removal.

06

Boundary: Not a Replacement for Team Discussion

What to watch: treating the prompt output as a final decision rather than a discussion artifact. Rule removal affects the entire team's workflow and may have political or cultural dimensions the model cannot see. Guardrail: route the output through a human approval step. The prompt should produce a recommendation with evidence, not execute the change. Pair with the Team Convention vs Linter Rule Conflict Resolution Prompt when team disagreement is likely.

Copy-Ready Prompt Template

Paste this prompt into your AI harness to audit a single linting rule's effectiveness using historical violation data.

This template is designed to be executed once per linting rule under review. It expects structured input about the rule's violation history, false positive rate, and fix rate over a defined time window. The output is a scored recommendation that platform teams can use to decide whether to keep, reconfigure, or remove the rule from their CI pipeline. The prompt enforces data-driven justification and explicitly asks the model to flag when evidence is insufficient for a confident recommendation.

text
You are an auditor evaluating the effectiveness of a single linting rule in a production codebase. Your goal is to produce a data-driven recommendation: keep, reconfigure, or remove the rule.

## INPUT DATA
- Rule ID: [RULE_ID]
- Rule Name: [RULE_NAME]
- Linter: [LINTER_NAME]
- Evaluation Window: [START_DATE] to [END_DATE]
- Total Violations Triggered: [TOTAL_VIOLATIONS]
- Confirmed False Positives: [FALSE_POSITIVES]
- Violations Fixed Within 30 Days: [FIXED_VIOLATIONS]
- Violations Suppressed with Justification: [SUPPRESSED_VIOLATIONS]
- Violations Still Open After 90 Days: [OPEN_VIOLATIONS]
- Rule Severity Level: [SEVERITY]
- Team Convention Alignment: [ALIGNMENT_DESCRIPTION]
- Additional Context: [ADDITIONAL_CONTEXT]

## OUTPUT SCHEMA
Return a JSON object with these fields:
- rule_id: string
- effectiveness_score: number (0.0 to 1.0, where 1.0 is highly effective)
- false_positive_rate: number (0.0 to 1.0)
- fix_rate: number (0.0 to 1.0, fixed violations / (total violations - false positives))
- recommendation: "keep" | "reconfigure" | "remove"
- confidence: "high" | "medium" | "low"
- justification: string (3-5 sentences explaining the recommendation with specific data points)
- suggested_reconfiguration: string | null (if reconfigure, describe the change; otherwise null)
- risks_of_removal: string (what could go wrong if this rule is removed)
- evidence_gaps: string[] (list any missing data that would improve confidence)

## SCORING GUIDELINES
- Effectiveness score should weigh fix rate more heavily than raw violation count.
- A rule with high false positive rate (>0.4) should lean toward reconfigure or remove unless the true positives catch critical issues.
- A rule with low fix rate (<0.3) and low severity should lean toward remove.
- A rule aligned with documented team conventions should be preserved even if metrics are moderate.
- If total violations are fewer than 10 in the evaluation window, set confidence to "low" and note insufficient data.

## CONSTRAINTS
- Do not recommend removal of security-critical rules (severity "critical" or "error") without a compensating control.
- If recommendation is "reconfigure," the suggested_reconfiguration field must be specific and actionable.
- Base all conclusions on the provided data. Do not invent violation counts or trends.
- If data is contradictory or incomplete, lower the confidence score and explain why in evidence_gaps.

Adapt this template by adjusting the scoring guidelines to match your team's risk tolerance. For example, teams with stricter quality gates might lower the acceptable false positive threshold from 0.4 to 0.2. The output schema is designed to feed directly into a dashboard or decision log, so keep the JSON structure stable across rule audits. Before running this prompt at scale, validate the output against a few manually reviewed rules to calibrate the scoring thresholds to your repository's actual patterns.

Implementation Harness Notes

How to wire the Linting Rule Effectiveness Audit Prompt into an application or workflow with validation, retries, and human review gates.

This prompt is designed to run as a batch audit job, not a real-time interactive query. The typical integration pattern is a scheduled pipeline (weekly or per-sprint) that fetches rule violation history from your linting database or CI artifact store, assembles the prompt context, calls the model, validates the output, and writes results to a dashboard or audit log. Because the prompt produces a keep/reconfigure/remove recommendation that may change team tooling, the output should always pass through a human review step before any linter configuration is modified in production.

Input assembly requires three data sources wired together before the prompt is called: (1) the rule definition and configuration from your linter config file, (2) violation history counts and trends from your CI or static analysis database (e.g., SonarQube, CodeClimate, SARIF archives), and (3) fix-rate and suppression-rate data from your version control history or issue tracker. If any of these sources is missing or incomplete, the prompt should receive an explicit [DATA_GAPS] note rather than silently producing a recommendation on partial data. Output validation should check that the response contains a parseable effectiveness score (0.0–1.0), a clear recommendation enum (keep, reconfigure, remove), and at least one data-backed justification. Use a schema validator or a lightweight LLM judge to confirm these fields exist and are well-formed before the result enters the review queue.

Retry logic should be minimal here. If validation fails, retry once with the validation errors appended as [CORRECTION_FEEDBACK]. If the second attempt also fails, flag the rule for manual audit rather than looping. Model choice favors models with strong structured output and reasoning capabilities (GPT-4o, Claude 3.5 Sonnet, or equivalent). Avoid smaller or faster models for this task because the prompt requires multi-factor trade-off reasoning across false positive rates, fix rates, and team impact—areas where weaker models tend to produce shallow or inconsistent recommendations. Logging should capture the rule ID, the effectiveness score, the recommendation, the model version, and the reviewer's final decision for auditability. Store these in a dedicated lint_rule_audit table or log stream, not buried in general application logs.

Human review workflow: route all remove recommendations and any reconfigure recommendations with an effectiveness score below 0.4 to a platform team member for approval. keep recommendations with scores above 0.7 can be auto-accepted if your team has established trust in the audit pipeline, but log the decision for retrospective review. Never auto-apply configuration changes from this prompt without human confirmation—removing a lint rule that catches rare but critical security patterns can introduce risk that the effectiveness score alone may not surface. Wire the review step into your existing ticketing system or a lightweight approval UI rather than building a custom review interface.

PRACTICAL GUARDRAILS

Common Failure Modes

What breaks first when auditing lint rule effectiveness and how to guard against it.

01

Garbage-In Scoring: Noisy History Data

What to watch: The audit prompt produces misleading effectiveness scores because the violation history is polluted by mass auto-fixes, bulk suppressions, or config changes that reset counts. The model treats every historical data point as equally meaningful. Guardrail: Pre-process violation history to flag and exclude bulk-change events. Require the prompt to weight recent data higher and to call out data-quality concerns explicitly in the output.

02

False Positive Blindness: Missing Ground Truth

What to watch: The prompt cannot distinguish a rule with a high false-positive rate from a rule that correctly catches real but frequently suppressed issues. Without suppression-reason data, the model assumes all suppressions are valid. Guardrail: Require suppression comments or categories as a required input field. Instruct the prompt to treat undocumented suppressions as 'unknown intent' and to flag them for human review rather than counting them as evidence of false positives.

03

Recency Bias: Ignoring Rule Dormancy

What to watch: A rule that fired heavily two years ago but has been silent for six months gets a high effectiveness score based on historical volume alone. The prompt fails to detect that the rule is now dormant and no longer relevant. Guardrail: Add a time-decay weighting instruction to the prompt. Require the output to include a 'recency trend' field (active, declining, dormant) and to downgrade recommendations for rules with no recent violations.

04

Fix-Rate Inflation: Auto-Fix Contamination

What to watch: Rules with auto-fix capabilities show artificially high fix rates because the tool, not the developer, resolved the violation. The prompt interprets this as evidence the rule is valuable when it may just be low-friction noise. Guardrail: Instruct the prompt to separate auto-fix resolutions from manual fixes in its analysis. Require the effectiveness score to discount auto-fix rates and to flag rules where >80% of fixes are automated as candidates for reconfiguration rather than celebration.

05

Recommendation Overreach: Removing Safety Rules

What to watch: The prompt recommends removing a security or correctness rule because it has low violation volume and a high suppression rate, failing to recognize that the rule acts as a safety net for rare but critical issues. Guardrail: Add a rule-category constraint that requires human approval for any 'remove' recommendation on rules tagged as security, safety, or correctness. Instruct the prompt to apply a higher evidence bar for removal recommendations on these categories.

06

Context Collapse: Ignoring Team Conventions

What to watch: The prompt evaluates a rule purely on quantitative metrics and recommends removal, but the rule enforces a team style convention that isn't captured in violation data. The recommendation contradicts documented team policy. Guardrail: Provide team convention documents as an optional input. Instruct the prompt to cross-reference any 'remove' recommendation against known conventions and to flag conflicts for human resolution rather than overriding policy.

IMPLEMENTATION TABLE

Evaluation Rubric

Use this rubric to test the Linting Rule Effectiveness Audit Prompt before shipping. Each criterion maps to a pass standard, a failure signal, and a concrete test method.

CriterionPass StandardFailure SignalTest Method

Effectiveness Score Calculation

Score is a number between 0.0 and 1.0 derived from fix rate, false positive rate, and violation frequency.

Score is missing, outside 0-1 range, or not traceable to input metrics.

Run prompt with known violation history; verify score formula matches documented calculation.

Keep/Reconfigure/Remove Recommendation

Recommendation is exactly one of 'keep', 'reconfigure', or 'remove' with a justification tied to the score and metrics.

Recommendation is missing, ambiguous, or contradicts the computed score without explanation.

Test with edge-case inputs: high fix rate + low FP (expect 'keep'), low fix rate + high FP (expect 'remove'), mixed signals (expect 'reconfigure').

Data-Driven Justification

Justification references specific metrics from [RULE_VIOLATION_HISTORY], [FALSE_POSITIVE_RATE], and [FIX_RATE].

Justification is generic, cites no input data, or hallucinates metrics not present in the input.

Diff justification text against input placeholders; confirm every claim maps to a provided data point.

Handling of Missing or Incomplete Data

When required metrics are null or missing, output flags the gap and either abstains or qualifies the recommendation with 'insufficient data'.

Prompt produces a confident recommendation despite missing critical inputs like [FIX_RATE].

Provide inputs with null [FIX_RATE] and [FALSE_POSITIVE_RATE]; verify output contains 'insufficient data' qualifier.

Output Schema Compliance

Output is valid JSON matching the [OUTPUT_SCHEMA] with all required fields present and correctly typed.

Output is missing required fields, contains extra untyped fields, or is not parseable JSON.

Validate output with a JSON Schema validator against the expected schema; check field types (score: number, recommendation: string, justification: string).

False Positive Rate Interpretation

High false positive rate is correctly identified as a negative signal for rule effectiveness and reflected in the score and recommendation.

High false positive rate is ignored or misinterpreted as a positive signal.

Provide input with [FALSE_POSITIVE_RATE] = 0.8 and low fix rate; verify recommendation leans toward 'remove' or 'reconfigure'.

Fix Rate Interpretation

High fix rate is correctly identified as a positive signal indicating the rule produces actionable findings.

High fix rate is ignored or treated as irrelevant to the effectiveness score.

Provide input with [FIX_RATE] = 0.9 and low false positive rate; verify recommendation leans toward 'keep'.

Violation Volume Trend Handling

When [VIOLATION_HISTORY] shows a declining trend, the prompt acknowledges improvement and factors it into the recommendation.

Trend data is ignored; recommendation is based only on point-in-time metrics without trend context.

Provide violation history with a clear downward trend over 6 months; verify justification mentions the trend.

ADAPTATION OPTIONS

Adapt This Prompt

How to adapt

Use the base prompt with a single linter's output and a small rule set (5–10 rules). Replace [RULE_HISTORY] with a CSV or JSON dump from your linter's reporting tool. Skip the statistical confidence checks and focus on the keep/reconfigure/remove recommendation structure.

Simplify the output schema to:

json
{
  "rule_id": "[RULE_ID]",
  "recommendation": "keep|reconfigure|remove",
  "rationale": "[ONE_SENTENCE]"
}

Watch for

  • Recommendations based on gut feel rather than violation frequency data
  • Missing false-positive rate when the linter doesn't track suppression comments
  • Overly aggressive removal suggestions for rules with low volume but high severity
