Codex Handoff: Anthropic Documentation Ingestion

Context

The vault has broad coverage of MCP, ADK, Firecrawl, OpenAI, and agentic workflow topics, but it has essentially no dedicated Anthropic documentation lane. Existing Anthropic references are mostly incidental:

MCP notes that mention Anthropic as the protocol originator
tooling references to ANTHROPIC_API_KEY
Claude-as-reviewer workflow notes
scattered mentions of the Anthropic Messages API in passing

There is currently no meaningful raw Anthropic docs corpus under 00_Raw/anthropic/, and there are no dedicated permanent notes for the Anthropic API surface.

Your job is to create the first bounded Anthropic ingestion lane without turning it into an open-ended research sprawl.

Directive

Build the first Anthropic documentation batch around API fundamentals and provider-specific operational patterns.

Scope for Batch 1

Ingest only the smallest high-value surface needed to make the vault operationally useful for Anthropic work:

Authentication and request model
Messages API structure
Streaming behavior
Tool use / structured tool calling
Error handling and rate limits
Prompt caching / context-management guidance, if clearly documented in the same corpus

Do not start with:

marketing/product overview pages
speculative model-comparison notes
Claude Code usage notes unless they are directly relevant to the API/tooling layer
safety policy pages unless they become necessary to explain an API behavior

Deliverables

1. Raw Corpus Staging

Create or populate:

00_Raw/anthropic/

Keep the corpus bounded and attributable. Prefer source captures that are narrow, stable, and clearly titled.

2. First Literature Note

Create:

01_Wiki/lit-anthropic-messages-api.md

This should be a source-grounded literature note summarizing the first-batch Anthropic API material, with explicit caveats where the docs are provider-specific, evolving, or operationally conditional.

3. First Permanent Notes

Create only the permanent notes clearly justified by the source set. Expected likely set:

01_Wiki/anthropic-messages-api.md
01_Wiki/anthropic-tool-use.md
01_Wiki/anthropic-streaming-patterns.md
01_Wiki/anthropic-error-handling.md

Optional:

01_Wiki/anthropic-prompt-caching.md

Only create the prompt-caching note if the raw corpus contains enough concrete guidance to justify a standalone permanent note.

4. Graph Integration

Wire the new Anthropic notes into existing vault surfaces where they naturally belong, likely including:

01_Wiki/index.md
01_Wiki/agentic-frameworks-moc.md
01_Wiki/agent-tools.md
relevant MCP / API / evaluation notes if the connection is real and not speculative

Prefer minimal, high-signal graph edits.

Execution Rules

Do not broaden the batch mid-session.
Do not create a dozen tiny notes from thin evidence.
Distinguish clearly between:
- documented Anthropic API behavior
- vault-local recommendations
- cross-provider comparisons or inferences
Use concrete caveats where provider behavior may shift over time.
Keep permanent notes implementation-facing, not brand-summary pages.

Verification

Before finalizing:

Run audit-yanp.ps1
Run check-broken-links.ps1
If the new notes are author: gemini-cli, run the Claude review loop with:
- 02_System/review-gemini-pages.ps1
Resolve any concrete revise findings before committing if practical

Suggested Commit Boundaries

Prefer separate commits for:

raw source capture
synthesized Anthropic notes
graph integration or review-tooling changes, if they expand beyond the note set

Do not mix unrelated maintenance or review-artifact files into this lane.

Stop Condition

This batch is complete when the vault has:

a real 00_Raw/anthropic/ corpus
one literature note for Anthropic API fundamentals
a small set of durable permanent notes for the Anthropic API surface
graph discoverability from the main wiki surfaces

Do not proceed to a second Anthropic batch in the same session unless the first batch is complete, reviewed, and committed cleanly.
