Quality bar
A checkable standard for the output — not adjectives. A skill without one is a description, not a generator.
The problem
Generic agents are fluent about everything and opinionated about nothing.
Ask one for an ADR and it returns a plausible document with five hedged options and no decision. The gap is not model capability — it is that nothing told it what a good ADR refuses to do. Every skilldrop skill carries that judgment with it.
What makes a skill
Every skill ships its own quality bar.
Four things are mandatory before a skill lands, enforced by validate.py in CI — not conventions someone might have followed.
Anti-patterns
The specific mistakes the skill refuses to make, named and countered with a passing example beside a failing one.
Acceptance evals
Realistic prompts with assertions, plus phrases that should not trigger the skill — so the description stays honest.
Model tier
A provider-neutral light/standard/heavy hint that travels with the skill, so cheap work runs cheap.
Portability
One folder. Every major agent.
The SKILL.md format is identical across tools; only the directory differs, and several tools deliberately read each other's. Paths below are the ones confirmed in the July 2026 survey.

tier
- accessibility-audit Adversarially audit a UI (component code, page markup, screenshot, or flow) against WCAG 2.2 AA — findings cited to specific success criteria, centered on the user and assistive tech each one blocks, severity-tagged, with a concrete fix and what a scanner would miss. Use when the user wants an accessibility review, a11y audit, WCAG check, or to find what blocks screen-reader / keyboard / low-vision users before shipping. heavy
- adr-generator Generate an Architecture Decision Record (ADR) from a context-decision-consequences brief. Supports the two common formats — MADR (Markdown Any Decision Records) and Michael Nygard's original ADR template. Use whenever the user wants to capture an architectural decision, write an ADR, or document a "we decided X because Y" moment. standard
- agent-budget Write the spend spec for an agentic workflow — per-stage model tiers, token caps with hard abort rules, a graceful-degradation order, and cost-per-outcome as the governing metric. Use when the user asks what an agent loop or multi-agent workflow should be allowed to spend, wants token/cost budgets and caps for AI automation, or got a surprise bill from an agent fleet. standard
- agent-loop-design Design a supervised agent loop — the generate→verify→gate cycle, observable exit criteria, hard iteration cap, human gates at irreversible steps, and failure routes — as a loop spec a team can implement in any agent harness. Use when the user wants to automate a recurring task with an AI agent loop, design a work loop / review loop / research loop, or asks "how do I stop my agent from running forever or shipping junk". standard
- agent-threat-model Threat-model an AI agent deployment against the lethal trifecta — private data, untrusted content, and an exfiltration vector — producing a per-capability matrix, a named architectural fix for every unsafe path, and a pre-launch checklist. Use before shipping an agent, when reviewing MCP server or tool permissions, when the user asks about prompt injection or data exfiltration risk, or when deciding whether an agent's capability surface is safe to expose. heavy
- agents-md-generator Generate or audit a repository's AGENTS.md — the agent-policy file Claude Code, Codex, Cursor, Copilot, Kiro and Antigravity read — with every command traced to real evidence in the repo, generic virtue instructions stripped, and forbidden actions named. Use when a repo has no AGENTS.md, when an existing one is stale or ignored, when onboarding a codebase to agentic coding, or when an agent keeps running commands that don't exist. standard
- ai-usage-report Generate a per-user or team-level report on how AI tools are being used — volume, breadth, and effectiveness signals (e.g. whether AI outputs landed in shipped artifacts vs were generated and discarded). Consumes usage-event logs exported from an MCP server or other telemetry source. Use when a manager or team lead needs to understand AI adoption beyond raw counts — including spotting "AI theater" where people invoke AI to claim usage but don't act on the outputs. standard
- api-contract-draft Draft an OpenAPI 3.1 contract from a feature brief or story — resource-oriented paths, a full error catalog (RFC 9457), pagination/idempotency/versioning decided not deferred, examples on every operation, plus a decisions log so review argues choices instead of YAML. Use when the user wants to design an API, draft an OpenAPI/Swagger spec, define request/response shapes, or agree a contract between frontend/backend or two teams before code. standard
- architecture-diagrams Generate architecture diagrams (Mermaid, PlantUML, C4) from a written description of a system. Supports AWS/Azure/GCP cloud topologies, microservice landscapes, sequence flows, container diagrams, and ER models. Use whenever the user asks for an architecture diagram, system sketch, flow diagram, or visualization of a design. standard
- audience-profile Translate an audience type (exec, board, technical, sales, investor, internal, partner, customer) into structural rules — slide count, density, tone, must-have sections, things to avoid. Reusable across deck-builder, slide-outliner, and exec-summary. Use whenever a stakeholder communication deliverable is being designed for a specific audience. light
- brief-intake Turn raw mess — a Slack thread, meeting transcript, Jira ticket, half-written Notion page, email chain, or paragraph of free-form context — into a structured brief that the downstream skill (adr-generator, design-doc, runbook-generator, exec-summary, deck-builder, tech-comparison-matrix) can consume without further intake. Use whenever the user has unstructured source material and is about to invoke another skilldrop skill, or when a draft is missing the load-bearing context the next step will need. standard
- bug-triage Turn a vague bug report (Slack message, support ticket, "it's broken on mobile sometimes") into an actionable ticket — searchable symptom title, numbered repro steps from a clean state, expected vs actual, severity separated from priority, evidence tagged reported-vs-verified, and labeled hypotheses instead of root-cause guesses. Use when the user wants to triage a bug, write up a bug report, turn a complaint into a ticket, or make a flaky issue actionable. standard
- business-case Build a business case for a build/buy/defer investment decision — do-nothing always included as the baseline, benefits quantified as re-runnable calculations with confidence tags, full costs (build + run + opportunity), ranges instead of false precision, and the flip-assumption named. Use when the user needs to justify an investment, write a business case, compare build vs buy vs defer, or get budget/sponsor approval for an initiative. heavy
- capacity-cost-model Build a capacity and cost model for a service or feature — sized from a demand driver and its growth curve, not from instance types; unit economics (cost per request/tenant/GB); peak-vs-average and headroom as explicit decisions; cost at 1×/3×/10× with scaling cliffs named; and the forgotten line items (egress, logging, NAT, non-prod) checklisted. Use when the user needs to estimate cloud/infra cost, size capacity for launch or growth, project the bill at scale, or find what's driving a cost. standard
- council-review Convene a council of distinct senior-engineer personas (Architect, Security, Operator/SRE, Pragmatist, User-Advocate, plus optional bench seats) to deliberate a decision, design, or code change — each takes an independent stance, the genuine disagreements are surfaced as named cruxes, and a Chair issues a reconciled verdict that records dissents and states what would change the decision. The "Claude Council." Use when a choice has real tradeoffs and one reviewer's voice isn't enough: architecture decisions, risky changes before merge, RFC/design scrutiny, "should we adopt X?", rewrite-vs-refactor, or a pre-mortem. heavy
- data-contract Draft a data contract for a dataset, table, or event stream consumed by others — schema with per-field semantics and units, measurable quality SLAs (freshness, completeness, validity, distribution), a schema-evolution policy that says what breaks consumers, a named owner, and PII classification. Use when the user is publishing a dataset/table/topic other teams depend on, needs a data contract, or wants to stop downstream pipelines breaking on silent schema or quality changes. standard
- db-schema-design Design a database schema from access patterns — paradigm chosen deliberately (relational/document/key-value/wide-column/graph), keys and partitioning driven by the actual queries, indexes mapped to predicates, money/time types right, and every read path verified to have a supporting access path. Use when the user is designing a data model, schema, or tables for a feature, choosing a database, or asks how to structure/store data. standard
- decision-log Extract decisions, action items, owners, and due dates from meeting notes, Slack threads, design-review transcripts, or any unstructured discussion. Produces a clean structured log the user can paste into a doc, tracker, or ADR queue. Use when the user has notes/threads/transcripts and asks for a "decision log", "action items", "what did we agree", or "follow-ups". light
- deck-builder Generate a real PowerPoint (.pptx) file from content, target audience, and a color palette. Produces structurally-appropriate decks (slide count, density, layout choice) tuned for the audience — execs, technical reviewers, sales prospects, investors, internal teams. Use when the user wants an actual editable .pptx, not just an outline. standard
- design-doc Generate a Google-style engineering design doc (problem, goals/non-goals, options considered, recommended approach, risks, rollout) from a feature brief or short description. Use when the user wants to draft a design doc, technical proposal, or one-pager for an engineering review. standard
- devils-advocate Adversarial review of just-generated code, run *after* an agent (or human) declares a feature done. Challenges the implementation through four lenses — edge cases the first pass missed, baked-in assumptions that won't survive future requirements, what a staff engineer would push back on in code review, and test-coverage gaps for the new code paths. Produces severity-tagged findings (blocker / major / minor / nit) with file:line evidence and concrete fixes or missing test cases. Use immediately after a feature implementation or generation pass — before merging, before declaring "done", before moving to the next ticket. heavy
- doc-critique Review an existing document — ADR, design doc, runbook, exec summary, tech-comparison matrix, deck outline, decision log — and produce a structured critique against the same quality bars the skilldrop generators enforce. Categorizes findings by severity (blocker / major / minor / nit), points to the exact section/line, and suggests a concrete fix for each. Use when the user wants a second-pair-of-eyes review before sharing a doc, or has been handed someone else's artifact and wants to know what to push back on. heavy
- exec-summary Compress a long technical document, design doc, or proposal into a one-page executive summary aimed at non-technical or time-poor stakeholders. Use when the user has a long doc and needs a 30-second readable version, or is writing a 1-pager for a steering committee, partner, or executive sponsor. standard
- feature-implement-loop Implement a feature or story so it ends up *verified*, not just generated. Takes a description + acceptance criteria, writes code and tests, then runs an adversarial review pass that hunts for gaps (broken edge cases, baked-in assumptions, uncovered acceptance criteria), and re-generates to close them — looping until the review is clean or a 3-round cap is hit. Use when handed a ticket / story / feature spec with acceptance criteria and the goal is shippable, self-checked code — not a first draft. standard
- figma-diagrams Work with Figma and FigJam files via the Figma REST API — read existing file structure, list frames/pages, post comments, and produce FigJam-importable diagram specs. Use when the user mentions a Figma URL, asks to inspect/audit a Figma file, wants to comment on a design programmatically, or wants their architecture diagram in Figma. standard
- guide-builder Turn raw notes, specs, or design material into an easy-to-follow guide, auto-styled to the content — a setup/quickstart, a design walkthrough, or an API/event-schema reference. Use when the user wants setup or getting-started instructions, an onboarding walkthrough of how a system works, or developer reference docs for an API or event schema — and it is NOT an SRE operational runbook (use runbook-generator) or a design proposal for review (use design-doc). standard
- incident-comms Draft audience-segmented updates during a live incident — customer status-page posts, internal stakeholder updates, and exec notifications — each leading with user-facing impact, never speculative cause or ETA, always naming the next-update time. Use when an incident is in progress and the user needs a status page post, customer notification, internal update, exec brief, or the resolved/all-clear message. standard
- llm-eval-harness Design an evaluation harness for an LLM-powered feature — a versioned golden set (representative + adversarial + regression cases), the cheapest adequate grading method per case, a metric with a pre-set pass bar and regression gate, and a failure taxonomy that targets iteration. Use when the user is building or tuning an LLM feature (prompt, RAG, agent, classifier) and needs evals, a way to test prompt/model changes, or to stop shipping quality regressions on vibes. standard
- migration-plan Generate a phased migration or rollout plan (schema change, API version, datastore swap, platform move, auth-provider switch) — expand→migrate→contract by default, every phase reversible or its point of no return named, observable gates between phases, idempotent backfill with parity checks. Use when the user needs a migration plan, cutover plan, rollout strategy, or asks "how do we get from X to Y without downtime". standard
- nfr-spec Sweep a feature or system through the full non-functional requirements catalog — performance, throughput, availability, durability, privacy/retention, accessibility, i18n, observability, operability, compatibility, cost — forcing every category to a measurable target, an explicit n/a, or a tagged default. Use when the user needs NFRs, quality attributes, "how fast/reliable does it need to be", SLO targets for a feature, or the requirements everyone forgets until they're incidents. standard
- observability-plan Design an observability plan for a service — user-journey SLIs, SLOs with error budgets, symptom-based burn-rate alerting (page vs ticket, every page actionable and runbook-linked), and a deliberate metrics/logs/traces split with a cardinality and cost budget. Use when the user needs SLOs, alerting design, a monitoring/observability strategy, dashboards, or wants to fix alert fatigue and know what to measure. standard
- okr-cascade Cascade company OKRs to team-level OKRs — with a gap registry for objectives no team credibly owns, and a causal metric tree connecting each team KR to the north-star it's supposed to move. Use when the user wants to set or cascade OKRs, align team goals to company goals, "turn strategy into quarterly objectives", or audit existing OKRs for gaps and vanity metrics. standard
- postmortem-generator Generate a blameless incident postmortem from raw material (Slack thread, pager timeline, notes) — quantified impact, UTC timeline with detection/mitigation gaps, contributing factors instead of a single root cause, and ≤8 verifiable action items. Use after an incident or outage when the user needs a postmortem, RCA, incident review, or "lessons learned" doc. standard
- prd-draft Draft a Product Requirements Document from a feature idea or brief — evidence-backed problem statement with zero solution language, testable MoSCoW-prioritized requirements, mandatory non-goals, and a success line per goal. Use when the user needs a PRD, wants to capture business requirements for a feature, or asks to turn an idea, pitch, or brief into a requirements doc. standard
- pre-merge-review Gate an existing change for merge — run one skill that fires the whole production-readiness pass. First a deterministic mechanical gate (lint + typecheck + tests, via a script whose exit code decides), then the three-reviewer panel dispatched in parallel — devils-advocate (correctness), security-reviewer (exploitability), code-quality (craft) — then a single READY / NOT READY verdict. Use before opening a PR or merging, when you want the full review fleet run on a diff you already have. Do NOT use to implement a feature from a spec (that's feature-implement-loop) or to review a document (that's doc-critique). standard
- prfaq Write an Amazon-style PR/FAQ — the launch press release for a product that doesn't exist yet, plus the customer FAQ and internal FAQ that force the hard questions before engineering starts. Use when the user wants a PRFAQ, a working-backwards document, a "write the press release first" exercise, or needs to align stakeholders on what a product must be before committing a team to build it. standard
- release-notes Turn git history between two refs into release notes — a customer-facing version written in reader benefits and an internal Keep-a-Changelog version with commit traceability, breaking changes always first. Use when the user wants release notes, a changelog, "what's in this release", a deploy announcement, or to summarize changes since the last tag. standard
- requirements-interview Generate per-stakeholder interview kits for feature discovery — ≤7 questions per stakeholder ranked by how much the answer changes the design, each naming the decision it informs, with at least one disconfirming question per script and an assumptions-to-validate ledger. Use when the user is gathering business requirements, preparing stakeholder or user interviews, or asks "what should I ask the sponsor/users/ops before we build this". standard
- reverse-architecture Reverse-engineer a system's architecture from what already exists — a code repo, Terraform / CloudFormation / Pulumi / Bicep, Kubernetes manifests, docker-compose, a database schema, an OpenAPI spec, or a package manifest — and produce a renderable diagram (Mermaid / C4 / PlantUML) plus a written description suitable for handing to architecture-diagrams. Use when the user wants to draw the system that *exists*, not one they're proposing — for onboarding docs, audit reviews, migration planning, or filling in a missing "as-is" architecture diagram. standard
- runbook-generator Generate an operational runbook for a service — covering deploy/rollback, common incidents, on-call escalation, SLOs, dashboards, and dependencies. Use when the user is launching a new service, onboarding to on-call, or being asked for "the runbook" by SRE or production-readiness review. standard
- slide-outliner Outline an architecture review or technical pitch deck — slide titles, key points per slide, and speaker notes. Does NOT generate PowerPoint/Keynote files; produces a structured outline the user can paste into any deck tool. Use when the user is preparing for an architecture review, design review, sales pitch, partner meeting, or steering-committee presentation. standard
- sonar-onboard Scaffold a repo for Sonar compliance — supports both **SonarQube server** (self-hosted) and **SonarCloud** (SaaS), user picks at setup time. Generates `sonar-project.properties` with language-correct source/test/coverage paths, a CI workflow that runs the scanner on every push and PR and blocks merge on quality-gate failure, and a README snippet documenting the gate. One-shot setup; pair with `sonar-review` for per-change feedback. Use when the user says "set up Sonar", "add SonarQube to this repo", "wire up SonarCloud", "set up the quality gate", or asks to make a project Sonar-compliant for the first time. light
- sonar-review Run a Sonar scan against the just-changed code on the current branch and produce a structured compliance report — quality-gate verdict (PASS / FAIL), then severity-tagged findings (🟥 blocker / 🟧 critical / 🟨 major / ⚪ minor / ⚪ info) scoped to changed files, each with file:line, the Sonar rule ID, the category (bug / vulnerability / security hotspot / code smell), why it matters, and a concrete fix. Works against both **SonarQube server** (self-hosted) and **SonarCloud** (SaaS) — mode is detected from `sonar-project.properties`. Sister skill to `devils-advocate`, but enforces Sonar's rule catalog and the project's quality gate rather than a hand-rolled lens sweep. Use after writing code, before pushing or opening a PR, when the user says "is this Sonar-compliant?", "run Sonar on this", "will the quality gate pass?", or any pre-merge compliance check. standard
- strategy-analysis Run a strategy framework — SWOT/TOWS, Porter's Five Forces, or PESTLE — on a product, company, or market question, choosing the right framework for the question and forcing every cell to carry evidence and a so-what. Use when the user asks for a SWOT, a competitive/market analysis, "should we enter this market", "what's our position against X", or a macro-environment scan. heavy
- subagent-design Decompose a task into an orchestrator and subagents — one-mission role cards with typed output contracts, a topology (pipeline / parallel / judge panel) chosen with a reason, context-isolation rationale, and a verification stage that is never a generator. Use when the user wants to fan work out across multiple agents, design a multi-agent workflow or orchestration, or asks "should this be one agent or several". standard
- success-metrics Define how a feature's success will be measured before it's built — one primary metric with target, timeframe, and baseline; guardrail and counter-metrics; an instrumentation plan naming every event; and a pre-committed decision rule for what happens if the target is missed. Use when the user asks "how do we know this worked", needs KPIs or success criteria for a feature, or wants a measurement/instrumentation plan before launch. standard
- tech-comparison-matrix Produce a weighted comparison matrix for a technology selection question (e.g., "Postgres vs DynamoDB", "Kafka vs Kinesis vs RabbitMQ", "Snowflake vs Databricks"). Surfaces criteria, weights, per-option scores, totals, and a recommended pick. Use when the user is choosing between technologies, vendors, frameworks, or architectural approaches. heavy
- test-plan-generator Generate a risk-based test plan for a feature, PR, or release — risks ranked by likelihood × impact, test cases pushed to the lowest pyramid level that catches the failure, every acceptance criterion mapped to a test, and an explicit "not tested" list. Use when the user asks for a test plan, test cases, a QA strategy for a change, "how should we test this", or pre-release test coverage. standard
- threat-model Produce a STRIDE threat model from a design doc, architecture description, or feature spec — assets and trust boundaries first, threats anchored to boundary crossings with concrete attack scenarios, severity-ranked with verifiable mitigations. Use when the user asks to threat-model a design, run a security review of an architecture, ask "how could this be attacked", or needs security sign-off input before build. heavy
- user-journey-map Map a customer's end-to-end journey toward an outcome — 3–6 stages, each with actions, emotions, pains, and opportunities, plus a rendered Mermaid emotion arc and the ranked pain points design should attack first. Use when the user wants a journey map, customer experience map, "map the user's path through onboarding", touchpoint analysis, or "where do users feel friction". standard
- user-story-splitter Split an epic, feature request, or PRD chunk into independently shippable user stories with testable Gherkin acceptance criteria and a recommended build order. Use whenever the user wants to "break this down", turn an epic or PRD into a backlog, slice a feature for sprint planning, or write acceptance criteria for a story. standard
