• Auditing Web Accessibility — $5.00 — Audits a web page or component against WCAG 2.2 AA, ordered by how much each failure blocks real use, with the specific fix for each finding. Use when reviewing a UI for accessibility, preparing a VPAT or compliance statement, fixing keyboard or screen-reader problems, or when the user mentions a11y, WCAG, contrast or ARIA.
• Reviewing Pull Requests — free — Reviews a pull request or diff for correctness bugs, missing tests and unclear naming, ranked by consequence rather than line order. Use when the user asks for a code review, shares a PR link or a diff, or asks whether a change is safe to merge.
• Writing Skills — free — Writes and revises Agent Skills so they are discovered and followed — frontmatter that validates, descriptions that match real requests, progressive disclosure, and the right degree of freedom. Use when creating a SKILL.md, editing an existing skill, packaging one for distribution, or working out why a skill never triggers.
• Writing Postmortems — free — Turns an incident into a blameless postmortem with a timeline, contributing factors and owned action items, using language that describes systems rather than assigning fault. Use after an outage, a data loss event, a failed deploy, or when the user asks for an incident report or RCA.
• Cleaning Tabular Data — free — Cleans messy CSV and spreadsheet exports — repairs headers, normalises dates and numbers, collapses duplicates and reports what changed — before any analysis is run on them. Use when a CSV will not parse, when columns are misaligned, or when the user mentions dirty data, deduplication or an export from another system.
• Interviewing Users — free — Plans and runs customer discovery interviews that surface what people actually did rather than what they say they would do, and turns transcripts into evidence. Use when preparing user research, validating a product idea, writing interview questions, or analysing what customers said.
• Reviewing Database Migrations — $5.00 — Reviews a schema migration for locks, downtime and irreversibility before it reaches production, and rewrites unsafe steps into an online sequence. Use when reviewing a migration or DDL change, adding a column or index to a large table, renaming or dropping anything, or when a deploy needs zero downtime.
• Debugging Systematically — free — Finds the cause of a bug by reproducing it, forming one hypothesis at a time and testing each against evidence, instead of changing code until symptoms disappear. Use when something fails intermittently, works locally but not in production, or when several attempted fixes have not held.
• Writing Commit Messages — free — Writes Conventional Commits messages from a staged diff, explaining why a change was made rather than restating what it changed. Use when the user asks for a commit message, mentions committing, or shares a diff and asks how to describe it.
