Summary:
- Document that MEDIA directives must be plain-text line-start metadata.
Verification:
- Source check: src/media/parse.ts only recognizes lines whose trimmed start begins with MEDIA: and skips fenced code blocks.
- PR CI: check-docs succeeded.
Generated media can be produced in intermediate tool results before the assistant chooses which assets to share in its final reply. This change keeps those intermediate files from being appended a second time when the final reply already names the assets to deliver, and tightens the media directive parsing around unsafe or ambiguous URLs.
Sweep recent (last ~5h) doc edits for two readability/uniformity issues:
- Replace 42 path-as-text links of the form '[/foo/bar](/foo/bar)' with
descriptive labels derived from each target page's frontmatter title
(e.g. '[Anthropic]', '[Token use and costs]', '[OpenAI-compatible
endpoints]'). Affected files include gateway/troubleshooting,
concepts/oauth, reference/session-management-compaction, and
reference/transcript-hygiene.
- Sentence-case Title-Cased headings and link text in Related sections
across codex-harness, model-providers, tools/plugin, sdk-runtime,
sdk-setup, prompt-caching, ci, cli/config, google-meet, browser,
rich-output-protocol, subagents, web/control-ui, while preserving
brand and proper-noun capitalization (OpenAI, Codex, Chrome, Parallels,
Z.AI, etc.).
