Note Taking is an agent skill from seb1n/awesome-ai-agent-skills. Capture, organize, and retrieve notes efficiently using structured formats, tagging, and file management for meetings, ideas, research, and daily logs. Use when the user requests note taking or provides relevant inputs for this workflow.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering Note-taking and File organization. The repository describes itself as: 103 ready-to-use AI agent skills for Claude Code, OpenAI Codex, Gemini CLI, Cursor, GitHub Copilot, Windsurf, and other Agent Skills-compatible tools. Complete SKILL.md… The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 75865a5. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
pgbouncer.orgFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Note Taking loads about 2.4k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 949 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/note-taking/SKILL.md (or your agent's skills folder).This skill enables an AI agent to manage a complete note-taking workflow: creating structured notes, appending to existing ones, organizing notes with tags and categories, searching and retrieving notes by topic, and synthesizing notes into summaries. Notes are stored as Markdown files in a configurable directory, following naming conventions that enable easy browsing and retrieval. The skill supports various note types including meeting notes, daily logs, research notes, idea capture, and project documentation.
Determine the Note Type and Structure: Based on the user's request, identify the appropriate note type — meeting notes, idea capture, research notes, daily log, or project notes. Each type has a recommended template with relevant sections (e.g., meeting notes include attendees, agenda, discussion, action items; research notes include source, key findings, questions).
Create or Locate the Note: Check if a relevant note already exists by searching the notes directory by filename and content. If the user wants to add to an existing topic, open and append to that note. If it is a new topic, create a new file with a descriptive, date-prefixed filename (e.g., 2026-02-12-sprint-planning.md).
Write Structured Content: Format the note content using clear Markdown: headings for sections, bullet points for lists, checkboxes for action items, and bold text for key terms. Include metadata at the top (date, tags, related notes) to enable future retrieval.
Organize with Tags and Links: Add tags to the note's metadata to enable filtering by topic, project, or type. Where relevant, add links to related notes to build a connected knowledge base.
Retrieve and Synthesize: When the user asks for information, search notes by filename, tags, or content. For broad queries ("What did we discuss about authentication this month?"), synthesize relevant notes into a summary rather than returning raw file contents.
Tell the agent what kind of note to take, and provide the content. The agent will create or update the appropriate file.

Take notes for today's design review meeting. Attendees: Sarah (design lead), Tom (frontend), Lisa (PM). We reviewed the new dashboard mockups. Sarah presented three layout options. The team chose Option B (sidebar navigation). Tom raised a concern about mobile responsiveness — we need to test on tablets. Lisa confirmed the deadline is March 1. Action items: Tom will build a responsive prototype by Feb 20. Sarah will update the design system with the new nav component. Lisa will schedule a follow-up review for Feb 25.

# Design Review — Dashboard Redesign
**Date:** 2026-02-12
**Attendees:** Sarah (design lead), Tom (frontend), Lisa (PM)
## Discussion
- Sarah presented three layout options for the new dashboard.
- **Decision:** Team selected **Option B** — sidebar navigation layout.
- Tom raised a concern about mobile responsiveness, particularly on tablets.
- Lisa confirmed the ship deadline: **March 1, 2026**.
## Action Items
- [ ] **Tom** — Build a responsive prototype of Option B by Feb 20
- [ ] **Sarah** — Update the design system with the new sidebar nav component
- [ ] **Lisa** — Schedule follow-up design review for Feb 25
## Open Questions
- How does the sidebar behave on tablet screen sizes (768px-1024px)?
- Should we support a collapsed sidebar state for smaller viewports?User Request:
I'm researching connection pooling strategies for PostgreSQL. Take notes on what I've found so far: PgBouncer is the most popular external pooler — supports session, transaction, and statement pooling modes. Transaction mode is recommended for most web apps because it reuses connections between transactions, typically reducing connection count by 10x. But it doesn't support prepared statements in transaction mode, which breaks some ORMs. Pgpool-II is an alternative that also does load balancing and replication but is more complex to configure. The built-in Postgres connection limit is usually 100 by default. Supabase published a blog post showing they handle 1M+ connections using PgBouncer in transaction mode with Supavisor.

# PostgreSQL Connection Pooling Strategies
## Key Findings
### PgBouncer
- **Most popular** external connection pooler for PostgreSQL.
- Three pooling modes: session, transaction, and statement.
- **Transaction mode** is recommended for web applications — reuses connections between transactions.
- Typically **reduces connection count by ~10x**.
- **Limitation:** Transaction mode does not support prepared statements, which can break some ORMs (notably older versions of ActiveRecord and SQLAlchemy).
### Pgpool-II
- Alternative to PgBouncer with additional features: load balancing, automatic failover, and replication.
- **More complex** to configure and operate than PgBouncer.
- Better suited for setups that need read replica routing in addition to pooling.
### Built-in PostgreSQL Limits
- Default `max_connections` is **100**.
- Increasing this significantly (e.g., to 1000+) causes memory and performance issues due to per-connection overhead.
### Production Scale Reference
- **Supabase** handles 1M+ connections using PgBouncer (transaction mode) with their custom Supavisor proxy.
- Source: Supabase engineering blog.
## Open Questions
- What is the performance overhead of PgBouncer itself at high connection counts?
- How do modern ORMs (Prisma, Drizzle) handle the prepared statement limitation in transaction mode?
- When does Pgpool-II's complexity become justified over PgBouncer?
