Offset: +21 minutes 43 seconds · Duration: 21 seconds

**User Request:**
for the sdk usage examples, i think this is a much better example: find . -name "*.py" | \
  claude -p "analyze these python files for security vulnerabilities and output just the risky file paths" | \
  xargs -I {} claude -p "suggest specific fixes for security issues in file: {}"

**Assistant Response:**
I'll update the SDK usage examples with that better example:

**Actions Taken:**

- **Edit**: `/Users/jflam/src/cc-video/claude-code-presentation.md`

**Assistant Response:**
Updated the SDK example with your suggested security vulnerability analysis pipeline - much better demonstration of chaining Claude commands together!

## Turn 7

Offset: +24 minutes 54 seconds · Duration: 12 seconds

**User Request:**
i want to add a section about "programming in english" which explores using claude code's slash command extensions to embody a specify workflow. here is what my new_feature command does in specify - add a slide that breaks this down (but keep it legible).

new_feature.md

Create a new feature specification with automatic branch creation and numbering.

Given the feature description "$ARGUMENTS", I need you to:

1. Find the repository root using `git rev-parse --show-toplevel`
2. Examine the `specs/` directory to find the highest numbered feature (e.g., if you see `001-chat` and `002-test-cleanup`, the highest is 002)
3. Generate the next feature number by incrementing by 1 with zero-padding (e.g., 002 → 003)
4. Transform the feature description into a branch name by:
 - Converting to lowercase
 - Replacing spaces and special characters with hyphens
 - Limiting to 2-3 meaningful words
 - Combining with feature number: `003-meaningful-name`
5. Create and switch to the new git branch
6. Create the feature directory: `specs/[branch-name]/`
7. Copy the template from `templates/feature-spec-template.md` to `specs/[branch-name]/feature-spec.md`
8. Replace these placeholders in the template:
 - `[FEATURE NAME]` with the feature description
 - `[###-feature-name]` with the branch name
 - `[DATE]` with current date (YYYY-MM-DD format)
 - `[feature name]` with the feature description
9. Confirm creation with branch name and file path

Use absolute paths with the repository root for all file operations to avoid path issues.

**Assistant Response:**
I'll add a section about "Programming in English" that breaks down your new_feature command:

**Actions Taken:**

- **Edit**: `/Users/jflam/src/cc-video/claude-code-presentation.md`

**Assistant Response:**
Added a "Programming in English" section that breaks down your new_feature command workflow in a digestible way, showing how natural language input gets transformed into a structured development workflow through slash command extensions.

Turn 15

Offset: +1 hour · Duration: 12 seconds

User Request: a point i want to end with is that while claude code is very good for code, it is good for general knowledge work as well, e.g., long form writing, generating presentations etc. agents are very good at text based workflows and can debug and diagnose very rapidly when things go wrong

Assistant Response: I'll add a closing slide that makes this broader point about Claude Code's utility beyond just coding:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md

Assistant Response: Added a slide emphasizing Claude Code's broader utility for general knowledge work and explaining why agents are particularly effective at text-based workflows.

Turn 16

Offset: +1 hour 2 minutes · Duration: 15 seconds

User Request: i want to tease some ideas about spec driven development too. for example, building a self-learning system through a systematic use of retrospectives at the end of an iteration that will update the context with learnings from that iteration. that feels like it belongs around the "Add Context" slide

Assistant Response: I'll add a slide about spec-driven development and self-learning systems around the "Add Context" section:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md

Assistant Response: Added a slide about spec-driven development that introduces the concept of self-learning systems through systematic retrospectives, positioned right after the context section to show how context can evolve and improve over time.

Turn 17

Offset: +1 hour 4 minutes · Duration: 9 seconds

User Request: the example is weak. a better one is "we learned that one of our new react components was an uncontrolled component - make sure we don't assume otherwise in the future"

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md

Assistant Response: Updated with your better example that's more technical and specific to the kind of architectural learnings that would be valuable to embed in future development cycles.

Turn 18

Offset: +1 hour 5 minutes · Duration: 29 seconds

User Request: spec driven development has a workflow of feature spec -> implementation plan -> code -> retrospective. each one has an iteration - this could be demo 4 actually

Assistant Response: You're right! This would make a great Demo 4. Let me restructure to add it as the fourth demo:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md
Edit: /Users/jflam/src/cc-video/claude-code-presentation.md

Assistant Response: Restructured to make spec-driven development Demo 4, showing the complete workflow cycle with slash commands for each phase and emphasizing how each step can iterate with Claude Code.

Turn 20

Offset: +1 hour 13 minutes · Duration: 15 seconds

User Request: there's another key idea in spec driven development around "what does the human do?" my hypothesis is that the human spends most of their time co-authoring the functional spec and the implementation plan, and ideally if this is done well very little time co-debugging the code. i want to tie this together with the "programming in english" idea with the slash functions in a single slide that talks about this

Assistant Response: I'll add a slide that connects spec-driven development with "programming in English" and focuses on what humans should spend their time on:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md

Assistant Response: Added a slide that connects spec-driven development with programming in English, showing the ideal human time allocation and your hypothesis that better specs lead to less debugging time.

Turn 22

Offset: +1 hour 16 minutes · Duration: 12 seconds

User Request: in general knowledge work, having text as intermediate files in the process helps the human audit and course correct if the agent gets it wrong

Assistant Response: I'll add that important point about text as intermediate files for auditing and course correction:

Actions Taken:

Turn 28

Offset: +1 hour 24 minutes · Duration: 14 seconds

User Request: can we make the slides align to the top? right now they look vertically centered?

Assistant Response: I'll add CSS to align the slides to the top. Let me modify the presentation to include custom styling:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md
Bash: Generate HTML presentation with top-aligned slides
```
marp claude-code-presentation.md
```
Bash: Open presentation with top alignment
```
open claude-code-presentation.html
```

Assistant Response: Added CSS to align slides to the top using justify-content: flex-start and compiled the presentation. The slides should now be top-aligned instead of vertically centered.

Turn 29

Offset: +1 hour 25 minutes · Duration: 42 seconds

User Request: not top-aligned - still centered. research how to do this and see if others have this problem

Assistant Response: Let me research how to fix the vertical alignment issue in Marp presentations:

Actions Taken:

WebSearch: { "query": "marp presentation slides vertical alignment top not centered css" }

Assistant Response: Let me try a different approach based on the research. The issue seems to be that Marp uses flexbox with center alignment by default. Let me try overriding this:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md
Bash: Generate HTML presentation with updated alignment CSS
```
marp claude-code-presentation.md
```
Bash: Open presentation with top alignment
```
open claude-code-presentation.html
```

Assistant Response: I've updated the CSS to include both justify-content: flex-start and align-items: flex-start with explicit flexbox properties. This should align the content to the top-left of each slide. The research shows this is a common issue with Marp's default centering behavior, and this approach should override it.

Turn 30

Offset: +1 hour 26 minutes · Duration: 41 seconds

User Request: can we make nested bullets a smaller font? are there styles or templates?

Assistant Response: Let me search for information about Marp bullet styling and nested list formatting:

Actions Taken:

WebSearch: { "query": "marp nested bullets smaller font size css styling" }

Assistant Response: Based on the research, I can add CSS to make nested bullets smaller. Let me update the style section in your presentation:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md
Bash: Generate HTML presentation with nested bullet styling
```
marp claude-code-presentation.md
```
Bash: Open presentation with smaller nested bullets
```
open claude-code-presentation.html
```

Assistant Response: Added CSS styling to make nested bullets progressively smaller:

Second-level bullets: 85% of normal size
Third-level bullets: 75% of normal size

The presentation is now compiled and open in your browser with the updated styling.

Turn 31

Offset: +1 hour 27 minutes · Duration: 19 seconds

User Request: now the code blocks are unreadable - the second level bullet points are still same size

Assistant Response: You're right - the CSS affected code blocks and the nested bullets didn't change. Let me fix this by being more specific with the selectors and excluding code blocks:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md
Bash: Generate HTML presentation with fixed styling
```
marp claude-code-presentation.md
```
Bash: Open presentation with corrected nested bullets and code blocks
```
open claude-code-presentation.html
```

Assistant Response: Fixed the CSS to:

Explicitly reset code block font sizes with !important to make them readable again
Use more specific selectors (ul li ul instead of ul ul) to target nested bullets more precisely

The presentation should now have properly sized code blocks and smaller nested bullets.

Turn 32

Offset: +1 hour 28 minutes · Duration: 1 minute 8 seconds

User Request: no - second level bullets same size. please research how to do this

Assistant Response: Let me research more specifically about Marp nested bullet styling issues:

Actions Taken:

WebSearch: { "query": "marp markdown nested bullets different font size CSS selectors" }

Assistant Response: Let me search for more specific information about Marp's HTML structure for nested lists:

Actions Taken:

WebSearch: { "query": ""marp" "ul ul li" nested list CSS HTML structure font-size" }

Assistant Response: Now I understand the issue better. Let me try a more specific approach using the correct CSS selectors for nested lists:

Actions Taken:

Edit: /Users/jflam/src/cc-video/claude-code-presentation.md
Bash: Generate HTML presentation with corrected nested bullet selectors
```
marp claude-code-presentation.md
```
Bash: Open presentation with properly styled nested bullets
```
open claude-code-presentation.html
```

Assistant Response: I changed the CSS selectors from ul li ul to li li which should be more effective. Based on the research, the issue was that I was targeting the wrong elements. Using li li targets nested list items directly, which should make the second-level bullets smaller (85%) and third-level bullets even smaller (75%).
