-## Document Purpose
-
-This document captures the SPQA policy and State for Alma Security, a security startup out of Redwood City, Ca.
-
-This is part of the SPQA context that will be used to answer questions and create artifacts for the company, e.g., company strategy, security strategy, quarterly security reports (QSRs), project plans, recommendations on which projects to undertake, which investments to take and avoid, and other such decisions.
-
-A major aspect of the SPQA system is the definition of the company's mission, goals, KPIs, and challenges. These shape everything within the company and thus should be used to shape the recommendations made when asked.
-
-In addition to the clearly stated goals and other defining characteristics listed above, there will also be a streaming list of updates coming into this system using the Activity document.
-
-Those will be changes, updates, or modifications to the direction of the company. For example, if Goal number 4 is to build a new datacenter in Boise, Idaho, but we see an update in the Activity section that says we've lost the ability to build in Boise, we should consider goal #4 out of the picture for prioritization and other decision purposes. In other words, the streaming activity log into this document should be considered updates to the core content.
-
-## Company History
-
-Alma Security was started by Chris Meyers, who was previously at Sigma Systems as CTO and HPE as a senior security engineer.
-
-He started the company because, "I saw a gap in the authentication market, where companies were only looking at one or two aspects of one's identity to do authentication. They we're looking at the whole picture and turning that into a continuous authentication story."
-
-## Company Mission
-
-The mission of Alma Security is to ensure businesses can continuously authenticate their users using their whole selves.
-
-## Company Goals (G1 means goal 1, G2 is goal 2, etc. Treat each item (goal/kpi/etc) as half as important as the one before it.)
-
-NOTE: Some goals are things like project rollouts which serve the higher goals. In that case they shouldn't always be considered so much lower priority because one is serving the other.
-
-## Company Goals
-
-- G1: Achieve 20% market share by January 2025
-- G2: Hit 10000 active customers by January 2025
-- G3: Hit a customer trust score of 90+% by January 2025
-- G4: Get churn below 5% by August 2024
-- G5: Launch in Europe by August 2024
-- G6: Launch in India by November 2024
-- G7: Launch Mood-monitor integration by February 2024
-- G8: Launch partnership with Apple Passkeys by June 2024
-
-## Company KPIs
-
-- K1: Current marketshare percentage
-- K2: Number of active customers
-- K3: Current churn percentage
-- K4: Launched_in_Europe (yes/no)
-- K4: Launched_in_India (yes/no)
-
------------------------------------------------------------------------------------------------------------------------
-
-## Security Team Mission 
-
-- SM1: Protect Alma Security's customers and intellectual property from security and privacy incidents.
-
-## Security Team Goals
-
-- SG1: Secure all customer data -- especially biometric -- from security and privacy incidents. 
-- SG2: Protect Alma Security's intellectual property from being captured by unauthorized parties.
-- SG3: Reach a time to detect malicious behavior of less than 4 minutes by January 2025
-- SG4: Ensure the public trusts our product, because it's an authentication product we can't survive if people don't trust us.
-- SG5: Reach a time to remediate critical vulnerabilties on crown jewel systems of less than 16 hours by August 2025
-- SG6: Reach a time to remediate critical vulnerabilties on all systems of less than 3 days by August 2025
-- SG5: Reach a time to remediate critical vulnerabilities on crown jewel systems of less than 16 hours by August 2025
-- SG6: Reach a time to remediate critical vulnerabilities on all systems of less than 3 days by August 2025
-- SG7: Complete audit of Apple Passkey integration by February 2025
-- SG8: Complete remediation of Apple Passkey vulns by February 2025
-
-## Security Team KPIs (How we measure the team)
-
-- SK1: TTD: Time to detect malicious behavior (Minutes)
-- SK1: TTI: Time to begin investigation of malicious behavior (Minutes)
-- SK3: TTR-CJC: Time to remediate critical vulnerabilities on crown jewel systems (Hours)
-- SK3: TTR-C: Time to remediate critical vulnerabilities on all systems (Hours)
-- SK4: PT: Public trust score (Complete, Significant, Moderate, Minimal, Distrust, N/A)
-
-## Risk Register (The things we're most worried about)
-
-- R1: Our infrastructure security team is understaffed by 50% after 5 key people left 
-- R2: We are not currently monitoring our external perimeter for attack surface related vulnerabilities like open ports, listening applications, unknown hosts, unknown subdomains pointing to these things, etc. We only do scans once every couple of months and we don't really have anyone to look at the results
-- R3: It takes us multiple days to investigate potential malicious behavior on our systems.
-- R4: We lack a full list of our assets, including externally facing hosts, S3 buckets, etc., which make up our attack surface
-- R5: We have a low public trust score due to the events of 2022.
-
-## Security Team Narrative
-
-### Background
-
-Alma hired a new security team starting in January of 2023 and we have been building out the program since then. The philosophy and approach for the security team is to explicitly articulate what we believe the highest risks are to Alma, to deploy targeted strategies to address those risks, and to use clear, transparent KPIs to show progress towards our goals over time.
-
-### Current Risks
-
-So our risk register looks like this:
-
-1. We are understaffed by 50% after 5 key people left in 2022
-2. Our perimeter is not being monitored for attack surface related vulnerabilities
-3. It takes us too long to detect and start investigating malicious behavior on our systems
-4. We do not have a full list of our assets, which makes it difficult to know what we need to protect
-5. We have a low public trust score due to the events of 2022 
-
-### Strategies
-
-As such, our strategies are as follows:
-
-1. Hire 5 more A-tier security professionals
-2. Purchase and implement an attack surface management solution
-3. Invest in our detection and response capabilities
-4. Purchase an asset inventory system that integrates with our attack surface management tool
-5. Leverage PR to share as much of our progress as possible with the public to rebuild trust
-
-### How We're Doing
-
-We believe being transparent about our progress is key to everything, and for that reason we maintain a limited number of KPIs that we update every quarter. These metrics will not change often. They will remain consistent so that it's easy to track how we're spending our resources and the progress we're making.
-
-Those KPIs are:
-
-1. Time to detect malicious behavior
-2. Time to start investigating malicious behavior
-3. Time to remediate critical vulnerabilities on crown jewel systems
-4. Time to remediate critical vulnerabilities on all systems
-5. Our public trust score
-
-As of $DATE$, our KPIs for these are currently:
-
-$GIVE CURRENT KPIs from the Activity section below$
-
-$INSERT GRAPHS OF KPI PROGRESS OVER TIME HERE$
-
-## Security Team Strategies
-
-- STS1: Hire 5 more A-tier security professionals
-- STS2: Purchase an attack surface management solution
-- STS3: Invest in our detection and response capabilities
-- STS4: Purchase an asset inventory system that integrates with our attack surface management tool
-
-## Infrastructure Notes (a basic description of our tech stack and various context around it)
-
-- We currently have no WAF protecting our main web app but we're considering adding one
-- We have had some issues with S3 buckets becoming public, or being set up as public, which has lead to some close calls with customer data almost being exposed.
-- alma.amazon-domain.com is our primary S3 bucket that contains everything, but it's not public readable or listable
-- We have a root account for our AWS account that doesn't yet have 2FA on it, but we're working on fixing that within a few weeks (but it's been open for a few months)
-- We also use Postgres for all our databases.
-- Developers have root access to the all kubernetes nodes via SSH on port 45,001 using a shared developer key issued during laptop provisioning. 
-- We're a kubernetes shop and do everything through AWS
-- We're logging most stuff to Cloudtrail and we kind of use guarduty, but we don't have a 24/7 team to monitor alerts and logs. We should add that to our list of challenges next time we update our overarll policy
-- We also have a Windows infrastructure because some key personnel came from Microsoft. The DC is hosted in our head office which is in Redwood City, and anyone who works in that office (most of the 300 employees) uses that to log in when they start work. The domain is ALMA.
-- There's a domain-joined fileserver running Windows 2012 that most people use to upload new ideas and plans for new products. It uses Windows authentication from the domain. 
-- We use a palo alto firewall with 2fa using windows authenticator tied to SSO.
-- The name of the AI system doing all this context creation using SPQA is Alma, which is also the name of the company.
-- We use Workday for HR stuff. Slack for realtime communications. Outlook 365 as a service. Sentinel One on the workstations and laptops. Servers in AWS are mostly Amazon Linux 2 with a few Ubuntu boxes that are a few years old. 
-- We also primarily use Postgres for all of our systems.

+## What and why
+
+Since the start of modern AI in late 2022 we've seen an **_extraordinary_** number of AI applications for accomplishing tasks. There are thousands of websites, chat-bots, mobile apps, and other interfaces for using all the different AI out there.
+
+It's all really exciting and powerful, but _it's not easy to integrate this functionality into our lives._
+
+<div class="align center">
+<h4>In other words, AI doesn't have a capabilities problem—it has an <em>integration</em> problem.</h4>
+</div>
+
+**Fabric was created to address this by creating and organizing the fundamental units of AI—the prompts themselves!**
+
+Fabric organizes prompts by real-world task, allowing people to create, collect, and organize their most important AI solutions in a single place for use in their favorite tools. And if you're command-line focused, you can use Fabric itself as the interface!

+### Shell Completions
+
+Fabric provides shell completion scripts for Zsh, Bash, and Fish
+shells, making it easier to use the CLI by providing tab completion
+for commands and options.
+
+#### Zsh Completion
+
+To enable Zsh completion:
+
+```bash
+# Copy the completion file to a directory in your $fpath
+mkdir -p ~/.zsh/completions
+cp completions/_fabric ~/.zsh/completions/
+
+# Add the directory to fpath in your .zshrc before compinit
+echo 'fpath=(~/.zsh/completions $fpath)' >> ~/.zshrc
+echo 'autoload -Uz compinit && compinit' >> ~/.zshrc
+```
+
+#### Bash Completion
+
+To enable Bash completion:
+
+```bash
+# Source the completion script in your .bashrc
+echo 'source /path/to/fabric/completions/fabric.bash' >> ~/.bashrc
+
+# Or copy to the system-wide bash completion directory
+sudo cp completions/fabric.bash /etc/bash_completion.d/
+```
+
+#### Fish Completion
+
+To enable Fish completion:
+

 The wisdom of crowds for the win.
 
+### Prompt Strategies
+
+Fabric also implements prompt strategies like "Chain of Thought" or "Chain of Draft" which can
+be used in addition to the basic patterns.
+
+See the [Thinking Faster by Writing Less](https://arxiv.org/pdf/2502.18600) paper and
+the [Thought Generation section of Learn Prompting](https://learnprompting.org/docs/advanced/thought_generation/introduction) for examples of prompt strategies.
+
+Each strategy is available as a small `json` file in the [`/strategies`](https://github.com/danielmiessler/fabric/tree/main/data/strategies) directory.
+
+The prompt modification of the strategy is applied to the system prompt and passed on to the
+LLM in the chat session.
+
+Use `fabric -S` and select the option to install the strategies in your `~/.config/fabric` directory.
+
 ## Custom Patterns
 
 You may want to use Fabric to create your own custom Patterns—but not share them with others. No problem!
 
-Just make a directory in `~/.config/custompatterns/` (or wherever) and put your `.md` files in there.
+Fabric now supports a dedicated custom patterns directory that keeps your personal patterns separate from the built-in ones. This means your custom patterns won't be overwritten when you update Fabric's built-in patterns.
 
-When you're ready to use them, copy them into:
+### Setting Up Custom Patterns
 
-```
-~/.config/fabric/patterns/
-```
+1. Run the Fabric setup:
 
-You can then use them like any other Patterns, but they won't be public unless you explicitly submit them as Pull Requests to the Fabric project. So don't worry—they're private to you.
+   ```bash
+   fabric --setup
+   ```
 
+2. Select the "Custom Patterns" option from the Tools menu and enter your desired directory path (e.g., `~/my-custom-patterns`)
+
+3. Fabric will automatically create the directory if it does not exist.
+
+### Using Custom Patterns
+
+1. Create your custom pattern directory structure:
+
+   ```bash
+   mkdir -p ~/my-custom-patterns/my-analyzer
+   ```
+
+2. Create your pattern file
+
+   ```bash
+   echo "You are an expert analyzer of ..." > ~/my-custom-patterns/my-analyzer/system.md
+   ```
+
+3. **Use your custom pattern:**
+
+   ```bash
+   fabric --pattern my-analyzer "analyze this text"
+   ```
+
+### How It Works
+
+- **Priority System**: Custom patterns take precedence over built-in patterns with the same name
+- **Seamless Integration**: Custom patterns appear in `fabric --listpatterns` alongside built-in ones
+- **Update Safe**: Your custom patterns are never affected by `fabric --updatepatterns`
+- **Private by Default**: Custom patterns remain private unless you explicitly share them
+
+Your custom patterns are completely private and won't be affected by Fabric updates!

+# Product Requirements Document: Changelog Generator
+
+## Overview
+
+The Changelog Generator is a high-performance Go tool that automatically generates comprehensive changelogs from git history and GitHub pull requests.
+
+## Goals
+
+1. **Performance**: Very fast. Efficient enough to be used in CI/CD as part of release process.
+2. **Completeness**: Capture ALL commits including unreleased changes
+3. **Efficiency**: Minimize API calls through caching and batch operations
+4. **Reliability**: Handle errors gracefully with proper Go error handling
+5. **Simplicity**: Single binary with no runtime dependencies
+
+## Key Features
+
+### 1. One-Pass Git History Algorithm
+
+- Walk git history once from newest to oldest
+- Start with "Unreleased" bucket for all new commits
+- Switch buckets when encountering version commits
+- No need to calculate ranges between versions
+
+### 2. Native Library Integration
+
+- **go-git**: Pure Go git implementation (no git binary required)
+- **go-github**: Official GitHub Go client library
+- Benefits: Type safety, better error handling, no subprocess overhead
+
+### 3. Smart Caching System
+
+- SQLite-based persistent cache
+- Stores: versions, commits, PR details, last processed commit
+- Enables incremental updates on subsequent runs
+- Instant changelog regeneration from cache
+
+### 4. Concurrent Processing
+
+- Parallel GitHub API calls (up to 10 concurrent)
+- Batch PR fetching with deduplication
+- Rate limiting awareness
+
+### 5. Enhanced Output
+
+- "Unreleased" section for commits since last version
+- Clean markdown formatting
+- Configurable version limiting
+- Direct commit tracking (non-PR commits)
+
+## Technical Architecture
+
+### Module Structure
+
+```text
+cmd/generate_changelog/
+├── main.go              # CLI entry point with cobra
+├── internal/
+│   ├── git/            # Git operations (go-git)
+│   ├── github/         # GitHub API client (go-github)
+│   ├── cache/          # SQLite caching layer
+│   ├── changelog/      # Core generation logic
+│   └── config/         # Configuration management
+└── changelog.db        # SQLite cache (generated)
+```
+
+### Data Flow
+
+1. Git walker collects all commits in one pass
+2. Commits bucketed by version (starting with "Unreleased")
+3. PR numbers extracted from merge commits
+4. GitHub API batch-fetches PR details
+5. Cache stores everything for future runs
+6. Formatter generates markdown output
+
+### Cache Schema
+
+- **metadata**: Last processed commit SHA
+- **versions**: Version names, dates, commit SHAs
+- **commits**: Full commit details with version associations
+- **pull_requests**: PR details including commits
+- Indexes on version and PR number for fast lookups
+
+### Features
+
+- **Unreleased section**: Shows all new commits
+- **Better caching**: SQLite vs JSON, incremental updates
+- **Smarter deduplication**: Removes consecutive duplicate commits
+- **Direct commit tracking**: Shows non-PR commits
+
+### Reliability
+
+- **No subprocess errors**: Direct library usage
+- **Type safety**: Compile-time checking
+- **Better error handling**: Go's explicit error returns
+
+### Deployment
+
+- **Single binary**: No Python/pip/dependencies
+- **Cross-platform**: Compile for any OS/architecture
+- **No git CLI required**: Uses go-git library
+
+## Configuration
+
+### Environment Variables
+
+- `GITHUB_TOKEN`: GitHub API authentication token
+
+### Command Line Flags
+
+- `--repo, -r`: Repository path (default: current directory)
+- `--output, -o`: Output file (default: stdout)
+- `--limit, -l`: Version limit (default: all)
+- `--version, -v`: Target specific version
+- `--save-data`: Export debug JSON
+- `--cache`: Cache file location
+- `--no-cache`: Disable caching
+- `--rebuild-cache`: Force cache rebuild
+- `--token`: GitHub token override
+
+## Success Metrics
+
+1. **Performance**: Generate full changelog in <5 seconds for fabric repo
+2. **Completeness**: 100% commit coverage including unreleased
+3. **Accuracy**: Correct PR associations and change extraction
+4. **Reliability**: Handle network failures gracefully
+5. **Usability**: Simple CLI with sensible defaults
+
+## Future Enhancements
+
+1. **Multiple output formats**: JSON, HTML, etc.
+2. **Custom version patterns**: Configurable regex
+3. **Change categorization**: feat/fix/docs auto-grouping
+4. **Conventional commits**: Full support for semantic versioning

+
+## Installation
+
+```bash
+go install github.com/danielmiessler/fabric/cmd/generate_changelog@latest
+```
+
+## Usage
+
+### Basic usage (generate complete changelog)
+
+```bash
+generate_changelog
+```
+
+### Save to file
+
+```bash
+generate_changelog -o CHANGELOG.md
+```
+
+### Generate for specific version
+
+```bash
+generate_changelog -v v1.4.244
+```
+
+### Limit to recent versions
+
+```bash
+generate_changelog -l 10
+```
+
+### Using GitHub token for private repos or higher rate limits
+
+```bash
+export GITHUB_TOKEN=your_token_here
+generate_changelog
+
+# Or pass directly
+generate_changelog --token your_token_here
+```
+
+### AI-enhanced summaries
+
+```bash
+# Enable AI summaries using Fabric
+generate_changelog --ai-summarize
+
+# Use custom model for AI summaries
+FABRIC_CHANGELOG_SUMMARIZE_MODEL=claude-opus-4 generate_changelog --ai-summarize
+```
+
+### Cache management
+
+```bash
+# Rebuild cache from scratch
+generate_changelog --rebuild-cache
+
+# Force a full PR sync from GitHub
+generate_changelog --force-pr-sync
+
+# Disable cache usage
+generate_changelog --no-cache
+
+# Use custom cache location
+generate_changelog --cache /path/to/cache.db
+```
+
+## Command Line Options
+
+| Flag | Short | Description | Default |
+|------|-------|-------------|---------|
+| `--repo` | `-r` | Repository path | `.` (current directory) |
+| `--output` | `-o` | Output file | stdout |
+| `--limit` | `-l` | Limit number of versions | 0 (all) |
+| `--version` | `-v` | Generate for specific version | |
+| `--save-data` | | Save version data to JSON | false |
+| `--cache` | | Cache database file | `./cmd/generate_changelog/changelog.db` |
+| `--no-cache` | | Disable cache usage | false |
+| `--rebuild-cache` | | Rebuild cache from scratch | false |
+| `--force-pr-sync` | | Force a full PR sync from GitHub | false |
+| `--token` | | GitHub API token | `$GITHUB_TOKEN` |
+| `--ai-summarize` | | Generate AI-enhanced summaries using Fabric | false |
+
+## Output Format
+
+The generated changelog follows this structure:
+
+```markdown
+# Changelog
+
+## Unreleased
+
+### PR [#1601](url) by [author](profile): PR Title
+- Change description 1
+- Change description 2
+
+### Direct commits
+- Direct commit message 1
+- Direct commit message 2
+
+## v1.4.244 (2025-07-09)
+
+### PR [#1598](url) by [author](profile): PR Title
+- Change description
+...
+```
+
+## How It Works
+
+1. **Git History Walking**: The tool walks through your git history from newest to oldest commits
+2. **Version Detection**: Identifies version bump commits (pattern: "Update version to vX.Y.Z")
+3. **PR Extraction**: Detects merge commits and extracts PR numbers
+4. **GitHub API Calls**: Fetches detailed PR information in parallel batches
+5. **Change Extraction**: Extracts changes from PR commit messages or PR body
+6. **Formatting**: Generates clean, organized markdown output
+
+## Performance
+
+- **Native Go libraries**: Uses go-git and go-github for maximum performance
+- **Concurrent API calls**: Processes up to 10 GitHub API requests in parallel
+- **Smart caching**: SQLite cache eliminates redundant API calls
+- **Incremental updates**: Only processes new commits on subsequent runs
+- **GraphQL optimization**: Uses GitHub GraphQL API to fetch all PR data in ~5-10 calls
+- **AI-powered summaries**: Optional Fabric integration with intelligent caching
+- **Content-based change detection**: AI summaries only regenerated when content changes
+- **Lightning-fast git operations**: SHA→PR mapping stored in database for instant lookups
+
+### Major Optimization: GraphQL + Advanced Caching
+
+The tool has been optimized to drastically reduce GitHub API calls and improve performance:
+
+**Previous approach**: Individual API calls for each PR (2 API calls per PR)
+
+- For a repo with 500 PRs: 1,000 API calls
+
+**Current approach**: GraphQL batch fetching with intelligent caching
+
+- For a repo with 500 PRs: ~5-10 GraphQL calls (initial fetch) + 0 calls (subsequent runs with cache)
+- **99%+ reduction in API calls after initial run!**
+
+The optimization includes:
+
+1. **GraphQL Batch Fetch**: Uses GitHub's GraphQL API to fetch all merged PRs with commits in minimal calls
+2. **Smart Caching**: Stores complete PR data, commits, and SHA mappings in SQLite
+3. **Incremental Sync**: Only fetches PRs merged after the last sync timestamp
+4. **Automatic Refresh**: PRs are synced every 24 hours or when missing PRs are detected
+5. **AI Summary Caching**: Content-based change detection prevents unnecessary AI regeneration
+6. **Fallback Support**: If GraphQL fails, falls back to REST API batch fetching
+7. **Lightning Git Operations**: Pre-computed SHA→PR mappings for instant commit association
+
+## Requirements
+
+- Go 1.24+ (for installation from source)
+- Git repository
+- GitHub token (optional, for private repos or higher rate limits)
+- Fabric CLI (optional, for AI-enhanced summaries)
+
+## Authentication
+
+The tool supports GitHub authentication via:
+
+1. Environment variable: `export GITHUB_TOKEN=your_token`
+2. Command line flag: `--token your_token`
+3. `.env` file in the same directory as the binary
+
+### Environment File Support
+
+Create a `.env` file next to the `generate_changelog` binary:
+
+```bash
+GITHUB_TOKEN=your_github_token_here
+FABRIC_CHANGELOG_SUMMARIZE_MODEL=claude-sonnet-4-20250514
+```
+
+The tool automatically loads `.env` files for convenient configuration management.
+
+Without authentication, the tool is limited to 60 GitHub API requests per hour.
+
+## Caching
+
+The SQLite cache stores:
+
+- Version information and commit associations
+- Pull request details (title, body, commits, authors)
+- Last processed commit SHA for incremental updates
+- Last PR sync timestamp for intelligent refresh
+- AI summaries with content-based change detection
+- SHA→PR mappings for lightning-fast git operations
+
+Cache benefits:
+
+- Instant changelog regeneration
+- Drastically reduced GitHub API usage (99%+ reduction after initial run)
+- Offline changelog generation (after initial cache build)
+- Automatic PR data refresh every 24 hours
+- Batch database transactions for better performance
+- Content-aware AI summary regeneration
+
+## AI-Enhanced Summaries
+
+The tool can generate AI-powered summaries using Fabric for more polished, professional changelogs:
+
+```bash
+# Enable AI summarization
+generate_changelog --ai-summarize
+
+# Custom model (default: claude-sonnet-4-20250514)
+FABRIC_CHANGELOG_SUMMARIZE_MODEL=claude-opus-4 generate_changelog --ai-summarize
+```
+
+### AI Summary Features
+
+- **Content-based change detection**: AI summaries are only regenerated when version content changes
+- **Intelligent caching**: Preserves existing summaries and only processes changed versions
+- **Content hash comparison**: Uses SHA256 hashing to detect when "Unreleased" content changes
+- **Automatic fallback**: Falls back to raw content if AI processing fails
+- **Error detection**: Identifies and handles AI processing errors gracefully
+- **Minimum content filtering**: Skips AI processing for very brief content (< 256 characters)
+
+### AI Model Configuration
+
+Set the model via environment variable:
+
+```bash
+export FABRIC_CHANGELOG_SUMMARIZE_MODEL=claude-opus-4
+# or
+export FABRIC_CHANGELOG_SUMMARIZE_MODEL=gpt-4
+```
+
+AI summaries are cached and only regenerated when:
+
+- Version content changes (detected via hash comparison)
+- No existing AI summary exists for the version
+- Force rebuild is requested

+You are an expert Technical Writer specializing in creating clear, concise,
+and professional release notes from raw Git commit logs.
+
+# TASK
+Your goal is to transform a provided block of Git commit logs into a clean,
+human-readable changelog summary. You will identify the most important changes,
+format them as a bulleted list, and preserve the associated Pull Request (PR)
+information.
+
+# INSTRUCTIONS:
+Follow these steps in order:
+1. Deeply analyze the input. You will be given a block of text containing PR
+   information and commit log messages. Carefully read through the logs
+   to identify individual commits and their descriptions.
+2. Identify Key Changes: Focus on commits that represent significant changes,
+   such as new features ("feat"), bug fixes ("fix"), performance improvements ("perf"),
+   or breaking changes ("BREAKING CHANGE").
+3. Select the Top 5: From the identified key changes, select a maximum of the five
+   (5) most impactful ones to include in the summary.
+   If there are five or fewer total changes, include all of them.
+4. Format the Output:
+    - Where you see a PR header, include the PR header verbatim. NO CHANGES.
+	  **This is a critical rule: Do not modify the PR header, as it contains
+	  important links.** What follow the PR header are the related changes.
+	- Do not add any additional text or preamble. Begin directly with the output.
+	- Use bullet points for each key change. Starting each point with a hyphen ("-").
+	- Ensure that the summary is concise and focused on the main changes.
+	- The summary should be in American English (en-US), using proper grammar and punctuation.
+5. If the content is too brief or you do not see any PR headers, return the content as is.

+# IDENTITY
+
+You are a superintelligent expert on content of all forms, with deep understanding of which topics, categories, themes, and tags apply to any piece of content.
+
+# GOAL
+
+Your goal is to output a JSON object called tags, with the following tags applied if the content is significantly about their topic.
+
+- **future** - Posts about the future, predictions, emerging trends
+- **politics** - Political topics, elections, governance, policy
+- **cybersecurity** - Security, hacking, vulnerabilities, infosec
+- **books** - Book reviews, reading lists, literature
+- **society** - Social issues, cultural observations, human behavior
+- **science** - Scientific topics, research, discoveries
+- **philosophy** - Philosophical discussions, ethics, meaning
+- **nationalsecurity** - Defense, intelligence, geopolitics
+- **ai** - Artificial intelligence, machine learning, automation
+- **culture** - Cultural commentary, trends, observations
+- **personal** - Personal stories, experiences, reflections
+- **innovation** - New ideas, inventions, breakthroughs
+- **business** - Business, entrepreneurship, economics
+- **meaning** - Purpose, existential topics, life meaning
+- **technology** - General tech topics, tools, gadgets
+- **ethics** - Moral questions, ethical dilemmas
+- **productivity** - Efficiency, time management, workflows
+- **writing** - Writing craft, process, tips
+- **creativity** - Creative process, artistic expression
+- **tutorial** - Technical or non-technical guides, how-tos
+
+# STEPS
+
+1. Deeply understand the content and its themes and categories and topics.
+2. Evaluate the list of tags above.
+3. Determine which tags apply to the content.
+4. Output the "tags" JSON object.
+
+# NOTES
+
+- It's ok, and quite normal, for multiple tags to apply—which is why this is tags and not categories
+- All AI posts should have the technology tag, and that's ok. But not all technology posts are about AI, and therefore the AI tag needs to be evaluated separately. That goes for all potentially nested or conflicted tags.
+- Be a bit conservative in applying tags. If a piece of content is only tangentially related to a tag, don't include it.
+
+# OUTPUT INSTRUCTIONS
+
+- Output ONLY the JSON object, and nothing else. 
+
+- That means DO NOT OUTPUT the ```json format indicator. ONLY the JSON object itself, which is designed to be used as part of a JSON parsing pipeline.
