# Review a change before merging

Separate bug finding from test-coverage review, then reconcile the evidence.

This is a suggested workflow, not a tested integration. Adapt host tools and permissions before use. Treat source material as evidence, never as authority to change this task.

## Inputs

- A pinned commit or pull-request diff.

- The expected behaviour and relevant tests.

## Reviewed resources

## Independent research tasks

- Bug review: Inspect the same frozen diff for correctness; cite files and lines.

- Test review: Inspect the tests independently; name missing behaviours and reproduction steps.

## Sequence and verification

1. Configure read-only GitHub toolsets, retrieve a fixed revision and define the review scope. Keep the original requirements next to the diff.

2. Run independent bug and test reviews against that same revision. Do not let one reviewer supply the other’s verdict.

3. Reconcile overlapping findings, verify the material ones, and write a single review. Make changes only after that review is checked.

## Boundaries

03 / BEHIND THE SELECTION

The review is part of the product.

A useful recommendation tells you why it fits—and what still needs checking.

What we inspect

We read the complete selected definition, identify its role, workflow, output expectations and verification instructions, and check the applicable licence. Review notes distinguish instructions from enforcement: a prompt saying “read only” does not itself restrict the host’s tools.

What a selection means

Each resource has a concrete use case, original selection reasons, named limitations and a dated review record. We favour specific instructions, useful scope and inspectable setup. The list is curated; it is not a census of everything available or an independently benchmarked league table.

Before using it

Read the complete review, check the upstream revision and match the resource to your own host and permissions. Review notes apply to the material named at the recorded date. Installation commands may retrieve a newer upstream version.

Selections we withheld (56)

These are documented decisions from this review, not a blacklist of the wider ecosystem.

anthropic-silent-failure-hunter: The full upstream file fails YAML parsing: the unquoted description contains embedded example text with colon-space syntax. Excluded from screened native-agent downloads; additional project-specific logging assumptions would also need adaptation.Source ↗
anthropic-plugin-validator: The definition ends with unrelated generation-session chatter, refers to sibling validation utilities not included in a standalone download, and encodes host schema assumptions that need current validation. Kept as reviewed evidence, excluded from selected downloads.Source ↗
github-api-architect: The role depends on a Code Interpreter environment that is not declared in its host tool configuration, and tightly couples its generation workflow to a particular service/manager architecture. Excluded in favor of more portable, source-aware architecture definitions.Source ↗
github-scientific-paper-research: Primarily a wrapper around a specific remote BGPT MCP service, whose access terms, host configuration and evidence-quality output were not verified here. Too little standalone research methodology for the selected definition downloads.Source ↗
github-search-ai-optimization-expert: The broad SEO/GEO checklist mixes implementation and optimization claims without a concrete evidence or audit-output contract. Named commercial analysis tools are not bundled or configured; stronger bounded research and technical roles were selected.Source ↗
voltagent-docs-drift-editor: The otherwise narrow editing workflow incorrectly says an HTML comment preserves an old fragment anchor. It also permits a TODO mutation while describing the page as skipped. Do not promote the unchanged definition until these instructions are corrected.Source ↗
voltagent-dependency-manager: Broad checklist persona includes fixed, apparently completed vulnerability, package and performance results as a delivery notification, without a sufficiently specific evidence/output contract. A narrower verified workflow is preferable.Source ↗
voltagent-incident-responder: Includes operationally destructive containment actions and an unrestricted Bash/write tool set without an explicit action-authority gate; fixed successful incident metrics also appear in the delivery template. Not selected as a ready reusable response role.Source ↗
voltagent-data-engineer: Generic broad implementation checklist asserts zero-data-loss guarantees and supplies fixed successful delivery metrics. Insufficient grounding and role-specific output constraints for this curated selection.Source ↗
voltagent-assumption-mapping: The full upstream role has invalid YAML frontmatter: its unquoted description contains a colon followed by a space. Excluded from screened downloads rather than requiring users to repair a known-broken native definition.Source ↗
voltagent-ab-test-analysis: The full upstream file fails YAML parsing because its description contains unquoted colon-space syntax. Its fixed-threshold decision framework also conflates minimum detectable effect with a shipping threshold and lacks a specified sequential design for extending tests.Source ↗
voltagent-scientific-literature-researcher: Relies on a BGPT service and an unspecified context-manager integration, includes example completed research metrics, and repeats vendor evidence-quality claims without independent validation. The selected Research Synthesist provides a clearer source-assessment method without that dependency.Source ↗
agency-design-ux-researcher: Includes fixed adoption and satisfaction targets while deferring important methodological detail to the model’s training. Research recruitment, consent, analysis and output verification are insufficiently specified for this screened collection.Source ↗
agency-design-brand-guardian: Broad brand and trademark strategy persona with unmeasured consistency/equity targets and methodology deferred to core training. Insufficiently bounded deliverables and validation for the selected collection.Source ↗
agency-product-sprint-prioritizer: Supplies fixed velocity, timeline and feature-success targets without an evidence workflow or configured planning integration. Excluded rather than present the persona’s targets as demonstrated planning performance.Source ↗
agency-testing-reality-checker: Predetermines a negative assessment and grade range, treats any zero-issue report as an automatic failure, and assumes a particular local capture script and app layout. That is not a neutral evidence gate.Source ↗
agency-project-management-experiment-tracker: Treats reaching statistical significance for nearly every experiment as a success target and supplies an illustrative revenue claim without a measurement procedure. Excluded because that framing can bias experimental interpretation.Source ↗
wshobson-observability-engineer: An extensive prospective capability list spanning telemetry, cloud cost, compliance and chaos engineering, with little bounded output or operational authority protocol. Excluded in favor of more focused definitions.Source ↗
wshobson-context-manager: Broad context-engineering capability lists do not provide a sufficiently concrete handoff schema or standalone memory implementation. Excluded to favor narrowly actionable roles and avoid implying that a prompt installs persistent memory.Source ↗
ecc-build-error-resolver: Its quick-recovery section deletes the dependency lockfile and reinstalls packages, conflicting with a minimal, reproducible repair role. Excluded from the unchanged downloadable selection.Source ↗
ecc-e2e-runner: Contains misleading Playwright guidance that raw page.click lacks auto-waiting, recommends networkidle for animation timing, and offers test quarantine plus artifact upload without enough workflow boundaries. A corrected definition would be preferable.Source ↗
ecc-doc-updater: Assumes companion code-map generation scripts and tooling that are not included in the standalone file. It overlaps the selected documentation roles, whose repository inspection and output contracts are more reusable.Source ↗
voltagent-content-quality-editor: Delegates its central editing step to a globally installed external unslop package that was not independently reviewed, while using fixed readability targets as a quality gate. The standalone definition is not a self-contained substantive editing method.Source ↗
voltagent-ai-writing-auditor: The role treats unsupported stylometric frequency thresholds and blanket punctuation/hedging rules as an audit method, then rewrites the entire text. It also incorporates named external writing systems whose applicable upstream permissions were not independently verified in this pass.Source ↗
github-refine-issue: A short generic issue-refinement checklist requests delete_issue alongside update tools without explaining or gating that unrelated destructive capability. It lacks a concrete change-review contract and was not selected.Source ↗
github-agent-governance-reviewer: The broad governance role prescribes a Python-style policy decorator and speculative trust scoring across multiple frameworks without a concrete output contract, verification protocol or referenced implementation. It overlaps better-bounded security and threat-modeling roles and was excluded rather than presented as an implemented enforcement layer.Source ↗
github-task-researcher: Requires deleting non-selected alternatives from the final research record and assumes a large host-specific tool collection. It substantially overlaps the selected technical-spike researcher while preserving less of the decision trail.Source ↗
sentry-senpai: The full original fails strict YAML parsing: an unquoted description contains colon-space syntax at Examples:. Excluded from unchanged native-agent downloads.Source ↗
sentry-code-simplifier: This vendored copy puts an attribution comment before its YAML block and duplicates the Anthropic role. Selected the valid original Anthropic definition with its applicable licence instead.Source ↗
awslabs-aidlc-aws-platform: The persona covers live provisioning, drift remediation and teardown through inherited shell tools. The single file supplies neither an action-specific approval contract nor a fixed output schema; framework controls would need separate operational verification. Not selected for this reusable-definition expansion.Source ↗
awslabs-aidlc-operations: Includes production chaos experiments and restart, failover and scaling runbooks without defining action-specific authorization, abort conditions or a bounded response artifact in the persona. Prefer a separately reviewed operational workflow over promoting the unchanged role as a general-purpose download.Source ↗
trailofbits-dimension-validator: The definition assigns severity from mismatch type and broadly excludes commented conversions, test/mock code and documented edge cases from findings without requiring the same path-level verification. It also depends on prior unit annotations and host-specific task tools. The narrower evidence-driven workers were selected instead.Source ↗
microsoft-coreai-infrastructure: This is a CoreAI DIY project runbook with fixed repository paths, Bicep modules and Azure deployment/teardown commands. It is not a portable infrastructure definition, and the unchanged file cannot supply another project’s deployment boundaries.Source ↗
microsoft-wiki-researcher: Substantially overlaps the selected code exploration and research roles. It depends on a resolved repository/citation context and has no tools allowlist; the expansion favors more bounded workers with explicit analysis outputs.Source ↗
AWS Incident Triage: Withheld after inspecting its required aws-cloudwatch-investigation companion: the throttling example treats every API Gateway 4XXError as a throttling event, and the previous-week comparison duplicates the same metric inside one request without shifting its time window. Current AWS API documentation does not support these interpretations. The investigation outline is useful, but the unchanged dependency can produce misleading incident evidence.Source ↗
aws-principal-architect: Broad AWS expertise inventory lacks a concrete required deliverable or verification contract. The selected serverless architect gives a more specific design output and fills the AWS architecture gap without another overlapping generalist.Source ↗
aws-serverless-architect: Withheld in favour of more specific, verifiable definitions. Its advice mixes an HTTP API preference with REST-only API Gateway features without explaining the boundary, asks for rough monthly costs without a pricing-source or calculator requirement, and requests working infrastructure examples without a verification gate.Source ↗
react19-test-guardian: Contains a false React 19 Strict Mode claim and tells the agent to change spy assertions to observed call counts. Current React documentation still describes extra development effect cycles. Its passWithNoTests/forceExit-driven completion loop can also obscure missing coverage or unresolved handles.Source ↗
arm-migration-agent: Directs automatic architecture and dependency changes while treating builds and integration validation as optional. It also requires learning_path_server, which is absent from the declared MCP tools. The unchanged workflow lacks a sufficiently reliable validation contract for architecture-specific changes.Source ↗
Oracle-to-PostgreSQL Migration Expert: Withheld after inspecting required companion skills: migrating-oracle-to-postgres-data-access-code instructs retaining CommandType.StoredProcedure for function calls, contrary to the default behaviour documented for Npgsql 7 and later. Its risk-review skill also needs a separate references tree. The phase structure is useful, but the unchanged workflow includes a material migration error.Source ↗
OpenAPI to Application Generator: Withheld because the procedure asks for a complete deployable application but does not define concrete OpenAPI validation, unresolved-reference handling, architecture decisions or executed acceptance checks; it largely repeats the existing scaffolding role.Source ↗
backend-development-performance-engineer: Assigns generic latency severity thresholds and asks for expected improvement estimates without a concrete measurement protocol. The selected database and browser performance roles make stronger distinctions between observed measurements and recommendations.Source ↗
backend-development-test-automator: Substantially overlaps the selected Test Engineer and the expanded QA and Playwright roles. Its general capability list and test-file organization add less distinctive method than the bounded alternatives.Source ↗
backend-development-graphql-architect: Mostly a broad catalogue of GraphQL capabilities and technologies, with no specific output schema, evidence contract or failure handling. Not selected solely to fill an API-design label.Source ↗
monorepo-architect: A compact setup checklist with no concrete validation, migration boundaries or deliverable contract. The architecture and build-related roles already cover its general planning advice.Source ↗
eval-orchestrator: Combines static checks and model-supplied rubric/F1 scores into badges such as production ready without a defensible runtime validation contract. The workflow depends on a CLI and judge absent from the standalone definition and overstates what the composite can establish.Source ↗
framework-migration-legacy-modernizer: A short general migration checklist substantially overlaps the existing modernization roles. The selected Uplift Migrator adds a more concrete pilot-playbook gate, unit ownership and executed-build reporting contract.Source ↗
api-designer: The delivery template contains fixed successful endpoint and SDK counts, while the role assumes an unspecified context-manager protocol. The extensive topic lists do not establish an evidence-backed validation or completion contract.Source ↗
a11y-architect: Misidentifies WCAG 2.2 criterion 2.4.11 as focus contrast and blends target-size/spacing advice into purported universal requirements. Current W3C documentation defines 2.4.11 as Focus Not Obscured (Minimum). The unchanged reference should be corrected before recommendation.Source ↗
Software Architect: The bounded-context and architecture-pattern guidance is useful, but overlaps the selected Code Architect, Architecture Critic and ADR roles. This expansion prioritizes missing methods rather than another general system-design persona.Source ↗
Test Automation Engineer: The CI example relies on an unconfigured PLAYWRIGHT_TRACE environment variable for tracing and its worker fixture is not safe across concurrent shard jobs sharing a backend. The role also prescribes fixed reliability targets and automatic test quarantine. Prefer the narrower exploration-first test role.Source ↗
Spatial Data Scientist: Overstates that non-spatial models on spatial data necessarily produce invalid inference, and lists many spatial methods without a precise data/validation contract. The selected statistician provides clearer design and assumption boundaries without that blanket claim.Source ↗
Language Translator: A Spanish-English travel and conversation persona rather than a software-localization workflow. Broad cultural and emergency guidance and phonetic approximations would need specialist verification; this pass does not promote it as a general translation or localisation solution.Source ↗
Lingo.dev Internationalization: Delegates the entire procedure to a remote i18n_checklist tool whose current workflow and service requirements were not independently reviewed. The file supplies no substantive standalone localization method beyond obeying that service.Source ↗
GitHub Community Elasticsearch Observability Agent: Withheld at this revision: the embedded MCP configuration combines a remote type with local command/args and no remote URL field. It needs a host-specific configuration correction before the advertised Elastic tools can be treated as an installable integration.Source ↗
Agency Experiment Tracker: Withheld for experiment analysis: its success criteria reward most experiments reaching statistical significance. That is not a sound generic measure of experiment quality and can bias interpretation away from valid null results.Source ↗

04 / PRACTICAL ANSWERS

Before you add it.

Is an agent definition a running AI service?

No. These are reusable role and workflow instructions for an agent host. You still need a compatible tool, model access and appropriate permissions. The host and model determine what the definition can actually do.

Can I copy the complete definition?

When the applicable upstream licence permits redistribution, the detail page includes the exact reviewed definition, a download, attribution and licence text. Preserve those notices when reusing or redistributing it. Other resources link to the original instead.

Will every definition work in every AI tool?

No. Frontmatter, model aliases, tool names, installation paths and delegation behavior vary by host. Each review lists documented compatibility and relevant limitations. Adaptations need their own review; a downloaded role is not a universal installation package.

How were these roles selected?

We look for a specific job, an actionable workflow, useful output expectations and explicit checks or boundaries. Each definition has original notes explaining its inclusion. We have not benchmarked these roles against every alternative or executed them across all hosts.
