- skill-authoringTencentCloudBase/CloudBase-AI-ToolkitDesign, improve, and evaluate reusable agent skills with high-quality SKILL.md files, precise trigger descriptions, progressive disclosure, and testable behavior. This skill should be used when users ask to create a new skill, rewrite or review an existing skill, audit a skill collection such as `config/source/skills` for redundancy or overlap, improve skill trigger quality, organize skill references, or evaluate whether a skill should trigger and behave correctly.DesignNo warnings★ 1.2K↓ —
- cwd-rolluphoangsonww/Claude-Code-Agent-MonitorRoll up Claude Code sessions by working directory (project) from Agent Monitor data — session count, total cost, total tokens, and last-active timestamp per cwd — so per-project activity can be compared at a glance. Use when summarizing where effort and spend went across projects.EngineeringNo warnings★ 1.1K↓ —
- data-exporthoangsonww/Claude-Code-Agent-MonitorExport Claude Code session and analytics data in JSON, CSV, or Markdown formats. Supports exporting sessions, events, costs, and analytics for external analysis or reporting. Use for data backup or integration.DataNo warnings★ 1.1K↓ —
- benchmarkhoangsonww/Claude-Code-Agent-MonitorBenchmark one session (or a small recent set) against the rolling average using Agent Monitor data — cost, total tokens, tool count, and workflow complexity score — and report where each metric lands as a percentile of the population. Tells you whether a session was normal, cheap, or an outlier. Use when judging whether a session was typical or out of band.ProductivityNo warnings★ 1.1K↓ —
- spec-to-repoalirezarezvani/claude-skillsUse when the user says 'build me an app', 'create a project from this spec', 'scaffold a new repo', 'generate a starter', 'turn this idea into code', 'bootstrap a project', 'I have requirements and need a codebase', or provides a natural-language project specification and expects a complete, runnable repository. Stack-agnostic: Next.js, FastAPI, Rails, Go, Rust, Flutter, and more.PlanningNo warnings★ 29.2K↓ —
- cmmc-readinessNewalirezarezvani/claude-skillsUse when a defense contractor or subcontractor is preparing for a CMMC 2.0 Level 2 self-assessment or C3PAO assessment, calculating or checking an SPRS score against NIST SP 800-171 Rev 2, deciding what can go on a POA&M, tracking POA&M closeout before Conditional status expires, or scoping assets, enclaves and cloud providers that handle CUI.

- ship-featurehoangsonww/Claude-Code-Agent-MonitorImplement a feature safely end-to-end in this repository. Use when adding or changing functionality across backend, frontend, or MCP with required verification and documentation updates.DesignNo warnings★ 1.1K↓ —
- harness-auditundefined-ui/second-brain-osAudit an agent's harness against the four rings: containment, guides, sensors, permissions. Use when the user asks whether their agent setup is safe, wants a review of sandboxing / permissions / hooks / AGENTS.md guardrails, or asks what a bad session could break. Read-only: reports the blast radius and a hardening list, changes nothing. Do NOT use for context layout (context-audit) or cost routing (gate-check).EngineeringNo warnings★ 1.2K↓ —
- evals-bootstrapundefined-ui/second-brain-osScaffold a first eval suite for an agent: mine real failures into cases, write behavioural checks over traces, and generate the runner. Use when the user wants evals, regression tests for an agent, a golden set, or asks how to know a prompt/model change did not break things. Do NOT use for a single task's done-check (goal-test) or for auditing context (context-audit).TestingNo warnings★ 1.2K↓ —
- md-documentalirezarezvani/claude-skillsUse when converting long-form markdown (spec, RFC, report, plan) into a single-file HTML page with sticky TOC, search and code-copy. Parses with markdown_parser.py and renders with html_renderer.py using the design-system brand.DesignNo warnings★ 29.2K↓ —
- landingalirezarezvani/claude-skillsUse when asked for a premium single-file HTML landing page with 3D CSS, GSAP scroll effects and parallax. Locks positioning in a short intake, validates the palette with brand_palette_validator.py and the output with html_validator.py.DesignNo warnings★ 29.2K↓ —
- second-brain-backfillundefined-ui/second-brain-osImport a large archive into the vault in controlled batches: triage what is worth ingesting, process oldest first, checkpoint after every batch, and keep cost visible. Use this skill whenever the user wants to import years of bookmarks, an export from another notes app, a downloads folder, a chat history dump, or says "backfill", "bulk import", "process my archive". Do NOT use for ingesting one or a few new sources, which is second-brain-ingest.ProductivityNo warnings★ 1.2K↓ —
- gate-checkundefined-ui/second-brain-osFind the decisions in a pipeline that do not need the expensive model and propose the gate for each: a rule, a classic classifier, or a small model, with fail-closed routing. Use when the user asks to cut model costs or latency, says the big model handles everything, or wants a triage / routing / filter layer in front of an agent. Analysis plus an optional baseline scaffold. Do NOT use for auditing context layout (context-audit) or for building eval suites (evals-bootstrap).ProductivityNo warnings★ 1.2K↓ —
- second-brain-changed-my-mindundefined-ui/second-brain-osTrace where the user's recorded position on something has shifted: superseded claims, contradictions between sources of different dates, and what evidence moved them. Use this skill when the user asks what they have changed their mind about, how their thinking on a topic developed, what they used to believe, or wants a quarterly look back at their own positions. Do NOT use for finding contradictions between sources with no time dimension, or for a current-state answer.OtherNo warnings★ 1.2K↓ —
- second-brain-renameundefined-ui/second-brain-osRename a page safely: update the file, fix every inbound wikilink, add the old name as an alias, and log it. Use this skill whenever a page needs a different canonical title, the user says "rename X to Y", asks to fix an inconsistent title, or after a lint run flags naming problems. Do NOT use for merging two pages, for moving a page between folders without a name change, or for renaming files outside the wiki.OtherNo warnings★ 1.2K↓ —
- second-brain-reviewundefined-ui/second-brain-osProduce a periodic review of a second-brain vault: what was added, which topics are growing, what contradicts what, which questions are still open, and what is worth reading next. Use this skill whenever the user asks for a weekly or monthly review, asks what changed in their vault, what they have been learning about lately, or what they should look at next, and when a scheduled review task fires. Do NOT use for structural linting, for ingesting sources, or for answering a specific factual question.EngineeringNo warnings★ 1.2K↓ —
- second-brain-metricsundefined-ui/second-brain-osRecord a dated snapshot of the vault's health numbers and compare against previous snapshots so trends are visible. Use this skill for a monthly or quarterly check, when the user asks whether the vault is improving, or asks to track its numbers over time. Do NOT use for a one-off graph analysis, which is second-brain-graph, or for structural repairs.OtherNo warnings★ 1.2K↓ —
- second-brain-privacyundefined-ui/second-brain-osAudit the vault for material that should not be in it: credentials, other people's private information, confidential work, and anything the user would not want synced or backed up. Use this skill when the user asks about privacy, is about to share or sync the vault, has just imported chat history or meeting notes, or asks what is sensitive in their notes. Do NOT use to delete anything on your own, or as a substitute for the publishing check.ProductivityNo warnings★ 1.2K↓ —
