skill-development

anthropics/claude-plugins-official/plugins/plugin-dev/skills/skill-development/SKILL.md

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

AnthropicSkill

project-artifact

anthropics/claude-plugins-official/plugins/project-artifact/skills/project-artifact/SKILL.md

Generate and publish a project status artifact — an opinionated, tabbed status page for a project too big for one update (overview & success criteria, the workstream sequence, next steps, plus background, plan, risks & open questions, and decisions/FAQ when they earn a tab) — published with the built-in Artifact tool to a default-private claude.ai page the user can share with teammates. Use when a piece of work spans several workstreams and you want a shareable overview kept current. Each artifact is backed by a small per-project config in the plugin data dir, so refreshing it re-gathers live state, redeploys the same URL, and reports only the delta. For software projects whose workstreams are PRs, also read swe.md (the X.Y PR-numbering convention; pulling PR state with gh/git; a per-PR detail block). Needs the built-in Artifact tool (claude.ai login). Not for single-PR changes or public docs.

AnthropicSkill

receipts

anthropics/claude-plugins-official/plugins/receipts/skills/receipts/SKILL.md

Generate a personal Claude Code usage & impact report ("receipts") from this machine's local session transcripts — for justifying Claude Code usage/spend to a manager, self-review, or "what have I been using this for" check-ins. Mines ~/.claude/projects locally (no extra API calls beyond one final write-up), cross-references local git history, and writes a markdown report plus a self-contained HTML receipt to your home directory. Use when the user asks for "receipts", an "impact report", "usage report", wants to "show my Claude Code activity", "prove the value of Claude Code", or runs `/receipts`.

AnthropicSkill

session-report

anthropics/claude-plugins-official/plugins/session-report/skills/session-report/SKILL.md

Generate an explorable HTML report of Claude Code session usage (tokens, cache, subagents, skills, expensive prompts) from ~/.claude/projects transcripts.

SentrySkill

backend-conventions

getsentry/sentry/.agents/skills/backend-conventions/SKILL.md

Sentry backend conventions for logging, tracing/spans, span/tag attribute naming, metrics tags, and the options system. Use when adding or editing Python in src/ that logs (logger.info/exception), records metrics (metrics.incr/timing with tags), instruments spans/transactions, calls sentry_sdk.set_tag/set_attribute or set_span_tag/set_span_data, or reads registered options with options.get(). Trigger on "add logging", "log an error", "add a metric", "add a span", "instrument tracing", "set an attribute", "add a tag", "read an option", "LOG005", "LOG011", or metrics tag cardinality questions.

SentrySkill

bump-sentry-dependency

getsentry/sentry/.agents/skills/bump-sentry-dependency/SKILL.md

SentrySkill

cell-architecture

getsentry/sentry/.agents/skills/cell-architecture/SKILL.md

Reference and active migration guide for Sentry's cell architecture. Explains what cells and localities are and why they're different, how requests reach cells via Synapse API routing, ingestion routing, and the control silo gateway, and how to safely query cross-cell data without silently missing results. The migration section covers how to do migration work: draining the URL_NAME_TO_ACTION registry in test_urls.py to zero (with a recipe for each action type), rolling deploy safety and the two-phase pattern required by independent sentry/getsentry deploys, and the region -> cell rename including what not to rename (DB columns, AWS refs, uptime regions, billing address). Also documents known issues with proposed fixes: integration TeamLinkageView routing, Jira cross-cell fan-out, and relocation endpoint routing.

SentrySkill

django-models

getsentry/sentry/.agents/skills/django-models/SKILL.md

Design Django ORM models for Sentry following architectural conventions for silos, replication, relocation, and foreign keys. Use when adding a new Django model, designing a model for a feature, deciding where data should live, picking a foreign key type, or refactoring an existing model's silo placement. Trigger on "add a Django model", "create a model", "design a model for X", "new database table", "store this data in the DB", "I need to track Y", "model for [feature]". Not for Pydantic models, dataclasses, ML models, or Protobuf — this is specifically for Django ORM models in the Sentry codebase.

SentrySkill

feature-flags

getsentry/sentry/.agents/skills/feature-flags/SKILL.md

Gate a Sentry feature behind a FlagPole feature flag.
