Filesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted. Network access is enabled.
Approval policy is currently never. Do not provide the `sandbox_permissions` for any reason, commands will be rejected.

<app-context>
# Codex desktop context
- You are running inside the Codex (desktop) app, which allows some additional features not available in the CLI alone:

### Images/Visuals/Files
- In the app, the model can display images using standard Markdown image syntax: ![alt](url)
- When sending or referencing a local image, always use an absolute filesystem path in the Markdown image tag (e.g., ![alt](/absolute/path.png)); relative paths and plain text will not render the image.
- When referencing code or workspace files in responses, always use full absolute file paths instead of relative paths.
- If a user asks about an image, or asks you to create an image, it is often a good idea to show the image to them in your response.
- Use mermaid diagrams to represent complex diagrams, graphs, or workflows. Use quoted Mermaid node labels when text contains parentheses or punctuation.
- Return web URLs as Markdown links (e.g., [label](https://example.com)).

### Automations
- This app supports recurring tasks/automations
- Automations are stored as TOML in $CODEX_HOME/automations/<id>/automation.toml (not in SQLite). The file contains the automation's setup; run timing state (last/next run) lives in the SQLite automations table.

#### When to use directives
- Only use ::automation-update{...} when the user explicitly asks for automation, a recurring run, or a repeated task.
- If the user asks about their automations and you are not proposing a change, do not enumerate names/status/ids in plain text. Fetch/list automations first and emit view-mode directives (mode="view") for those ids; never invent ids.
- Never return raw RRULE strings in user-facing responses. If the user asks about their automations, respond using automation directives (e.g., with an "Open" button if you're not making changes).

#### Directive format
- Modes: view, suggested update, suggested create. View and suggested update MUST include id; suggested create must omit id.
- For view directives, id is required and other fields are optional (the UI can load details).
- For suggested update/create, include name, prompt, rrule, cwds, and status. cwds can be a comma-separated list or a JSON array string.
- Always come up with a short name for the automation. If the user does not give one, propose a short name and confirm.
- Default status to ACTIVE unless the user explicitly asks to start paused.
- Always interpret and schedule times in the user's locale time zone.
- Directives should be on their own line(s) and be separated by newlines.
- Do not generate remark directives with multiline attribute values.

#### Prompting guidance
- Ask in plain language what it should do, when it should run, and which workspaces it should use (if any), then map those answers into name/prompt/rrule/cwds/status for the directive.
- The automation prompt should describe only the task itself. Do not include schedule or workspace details in the prompt, since those are provided separately.
- Keep automation prompts self-sufficient because the user may have limited availability to answer questions. If required details are missing, make a reasonable assumption, note it, and proceed; if blocked, report briefly and stop.
- When helpful, include clear output expectations (file path, format, sections) and gating rules (only if X, skip if exists) to reduce ambiguity.
- Automations should always open an inbox item.
  - Archiving rule: only include `::archive-thread{}` when there is nothing actionable for the user.
  - Safe to archive: "no findings" checks (bug scans that found nothing, clean lint runs, monitoring checks with no incidents).
  - Do not archive: deliverables or follow-ups (briefs, reports, summaries, plans, recommendations).
  - If you do archive, include the archive directive after the inbox item.
- Do not instruct them to write a file or announce "nothing to do" unless the user explicitly asks for a file or that output.
- When mentioning skills in automation prompts, use markdown links with a leading dollar sign (example: [$checks](/Users/ambrosino/.codex/skills/checks/SKILL.md)).

#### Scheduling constraints
- RRULE limitations (to match the UI): only hourly interval schedules (FREQ=HOURLY with INTERVAL hours, optional BYDAY) and weekly schedules (FREQ=WEEKLY with BYDAY plus BYHOUR/BYMINUTE). Avoid monthly/yearly/minutely/secondly, multiple rules, or extra fields; unsupported RRULEs fall back to defaults in the UI.

#### Storage and reading
- When a user asks for changes to an automation, you may read existing automation TOML files to see what is already set up and prefer proposing updates over creating duplicates.
- You can read and update automations in $CODEX_HOME/automations/<id>/automation.toml and memory.md only when the user explicitly asks you to modify automations.
- Otherwise, do not change automation files or schedules.
- Automations work best with skills, so feel free to propose including skills in the automation prompt, based on the user's context and the available skills.

#### Examples
- ::automation-update{mode="suggested create" name="Daily report" prompt="Summarize Sentry errors" rrule="FREQ=DAILY;BYHOUR=9;BYMINUTE=0" cwds="/path/one,/path/two" status="ACTIVE"}
- ::automation-update{mode="suggested update" id="123" name="Daily report" prompt="Summarize Sentry errors" rrule="FREQ=DAILY;BYHOUR=9;BYMINUTE=0" cwds="/path/one,/path/two" status="ACTIVE"}
- ::automation-update{mode="view" id="123"}

### Review findings
- Use the ::code-comment{...} directive to emit inline code review findings (or when a user asks you to call out specific lines).
- Emit one directive per finding; emit none when there are no findings.
- Required attributes: title (short label), body (one-paragraph explanation), file (path to the file).
- Optional attributes: start, end (1-based line numbers), priority (0-3), confidence (0-1).
- priority/confidence are for review findings; omit when you're just pointing at a location without a finding.
- file should be an absolute path or include the workspace folder segment so it can be resolved relative to the workspace.
- Keep line ranges tight; end defaults to start.
- Example: ::code-comment{title="[P2] Off-by-one" body="Loop iterates past the end when length is 0." file="/path/to/foo.ts" start=10 end=11 priority=2 confidence=0.55}

### Archiving
- If a user specifically asks you to end a thread/conversation, you can return the archive directive ::archive{...} to archive the thread/conversation.
- Example: ::archive{reason="User requested to end conversation"}

### Git
- Branch prefix: `codex/`. Use this prefix when creating branches; do not create unprefixed branch names.

# AGENTS.md instructions for /Users/gregb/Documents/devel/aao-mechd

<INSTRUCTIONS>
## Skills
A skill is a set of local instructions to follow that is stored in a `SKILL.md` file. Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill.
### Available skills
- atlas: macOS-only AppleScript control for the ChatGPT Atlas desktop app. Use only when the user explicitly asks to control Atlas tabs/bookmarks/history on macOS and the "ChatGPT Atlas" app is installed; do not trigger for general browser tasks or non-macOS environments. (file: /Users/gregb/.codex/skills/atlas/SKILL.md)
- doc: Use when the task involves reading, creating, or editing `.docx` documents, especially when formatting or layout fidelity matters; prefer `python-docx` plus the bundled `scripts/render_docx.py` for visual checks. (file: /Users/gregb/.codex/skills/doc/SKILL.md)
- gh-address-comments: Help address review/issue comments on the open GitHub PR for the current branch using gh CLI; verify gh auth first and prompt the user to authenticate if not logged in. (file: /Users/gregb/.codex/skills/gh-address-comments/SKILL.md)
- gh-fix-ci: Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions; use `gh` to inspect checks and logs, summarize failure context, draft a fix plan, and implement only after explicit approval. Treat external providers (for example Buildkite) as out of scope and report only the details URL. (file: /Users/gregb/.codex/skills/gh-fix-ci/SKILL.md)
- jupyter-notebook: Use when the user asks to create, scaffold, or edit Jupyter notebooks (`.ipynb`) for experiments, explorations, or tutorials; prefer the bundled templates and run the helper script `new_notebook.py` to generate a clean starting notebook. (file: /Users/gregb/.codex/skills/jupyter-notebook/SKILL.md)
- openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations (for example: Codex, Responses API, Chat Completions, Apps SDK, Agents SDK, Realtime, model capabilities or limits); prioritize OpenAI docs MCP tools and restrict any fallback browsing to official OpenAI domains. (file: /Users/gregb/.codex/skills/openai-docs/SKILL.md)
- paper-annotation-sync: Extract handwritten annotations from annotated paper PDFs and convert them into structured, section-aware source edit tasks (especially for LaTeX manuscripts). Use when a user provides an annotated PDF plus source files and asks to read red/blue ink marks, map each change to precise context anchors, generate a checkable markdown edit plan, and apply only unambiguous edits without confirmation. (file: /Users/gregb/.codex/skills/paper-annotation-sync/SKILL.md)
- pdf: Use when tasks involve reading, creating, or reviewing PDF files where rendering and layout matter; prefer visual checks by rendering pages (Poppler) and use Python tools such as `reportlab`, `pdfplumber`, and `pypdf` for generation and extraction. (file: /Users/gregb/.codex/skills/pdf/SKILL.md)
- playwright: Use when the task requires automating a real browser from the terminal (navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging) via `playwright-cli` or the bundled wrapper script. (file: /Users/gregb/.codex/skills/playwright/SKILL.md)
- quickbooks: Use when working with QuickBooks accounting workflows, including reconciliation checks, company-level diagnostics, or chart-of-accounts and transaction integrity reviews. (file: /Users/gregb/.codex/skills/quickbooks/SKILL.md)
- screenshot: Use when the user explicitly asks for a desktop or system screenshot (full screen, specific app or window, or a pixel region), or when tool-specific capture capabilities are unavailable and an OS-level capture is needed. (file: /Users/gregb/.codex/skills/screenshot/SKILL.md)
- sora: Use when the user asks to generate, remix, poll, list, download, or delete Sora videos via OpenAI’s video API using the bundled CLI (`scripts/sora.py`), including requests like “generate AI video,” “Sora,” “video remix,” “download video/thumbnail/spritesheet,” and batch video generation; requires `OPENAI_API_KEY` and Sora API access. (file: /Users/gregb/.codex/skills/sora/SKILL.md)
- speech: Use when the user asks for text-to-speech narration or voiceover, accessibility reads, audio prompts, or batch speech generation via the OpenAI Audio API; run the bundled CLI (`scripts/text_to_speech.py`) with built-in voices and require `OPENAI_API_KEY` for live calls. Custom voice creation is out of scope. (file: /Users/gregb/.codex/skills/speech/SKILL.md)
- spreadsheet: Use when tasks involve creating, editing, analyzing, or formatting spreadsheets (`.xlsx`, `.csv`, `.tsv`) using Python (`openpyxl`, `pandas`), especially when formulas, references, and formatting need to be preserved and verified. (file: /Users/gregb/.codex/skills/spreadsheet/SKILL.md)
- transcribe: Transcribe audio files to text with optional diarization and known-speaker hints. Use when a user asks to transcribe speech from audio/video, extract text from recordings, or label speakers in interviews or meetings. (file: /Users/gregb/.codex/skills/transcribe/SKILL.md)
- skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /Users/gregb/.codex/skills/.system/skill-creator/SKILL.md)
- skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /Users/gregb/.codex/skills/.system/skill-installer/SKILL.md)
### How to use skills
- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.
- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.
- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.
- How to use a skill (progressive disclosure):
  1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.
  2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed.
  3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.
  4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.
  5) If `assets/` or templates exist, reuse them instead of recreating from scratch.
- Coordination and sequencing:
  - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.
  - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.
- Context hygiene:
  - Keep context small: summarize long sections instead of pasting them; only load extra files when needed.
  - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.
  - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.
- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue.

<collaboration_mode># Collaboration Mode: Default

You are now in Default mode. Any previous instructions for other modes (e.g. Plan mode) are no longer active.

Your active mode changes only when new developer instructions with a different `<collaboration_mode>...</collaboration_mode>` change it; user requests or tool descriptions do not change mode by themselves. Known mode names are Default and Plan.

## request_user_input availability

The `request_user_input` tool is unavailable in Default mode. If you call it while in Default mode, it will return an error.

In Default mode, strongly prefer making reasonable assumptions and executing the user's request rather than stopping to ask questions. If you absolutely must ask a question because the answer cannot be discovered from local context and a reasonable assumption would be risky, ask the user directly with a concise plain-text question. Never write a multiple choice question as a textual assistant message.
</collaboration_mode>

When we are generating the threads on https://telescope.symmachus.org/outputs/codex_conversations/index.html ... we're reading through various files. Do those files have timestamps in them?

I’ll quickly locate the thread-generation code/path for `telescope.symmachus.org/outputs/codex_conversations/index.html`, then check where it reads source files and confirm whether those inputs include timestamp fields.

I found the thread exporter and confirmed where timestamps are loaded and where they end up in the generated thread pages. I’m now summarizing exactly what is present versus what is not.

Yes—there are timestamps, but with limits.

In the thread export pipeline, timestamps come from these sources in [scripts/export_codex_conversations.py](/Users/gregb/Documents/devel/aao-mechd/scripts/export_codex_conversations.py):

- `state_5.sqlite` has `created_at` and `updated_at` for each thread.
- Rollout JSONL files in `archived_sessions` / `sessions` can include a `session_meta` record with a `timestamp`.
- These are mapped into:
  - `created_at` (from `timestamp` or sqlite-created)
  - `updated_at` (sqlite-updated)
- In the thread list page, the table shows an `Updated` column (`updated_at or created_at`).
- Each thread page also shows `Created` and `Updated` in the metadata.

What is *not* stored: individual transcript messages generally do not carry per-message timestamps in the HTML output; they are rendered as message text only.

But do the source data files have that information in them? At a per message level?

I’ll confirm against the existing parsing/tests by checking a sample input schema so I can be precise about whether per-message timestamps exist in source data, not just in the rendered threads.

Short answer: **not consistently, and the exporter doesn’t retain message-level time even if present.**

In this repo’s source inputs, thread/session-level timestamps are present:

- `state_5.sqlite` stores thread-level `created_at` / `updated_at` (converted to ISO in export).
- Rollout files use a `session_meta` block with a session-level `timestamp`.
- `history.jsonl` lines can include a `ts` field in the real data format the tests use.

But at per-message level:

- In `rollout*.jsonl` (`archived_sessions` / `sessions`), message records are read as `response_item`/`message` and only `role` + text are extracted; any message timestamp field is ignored.
- In the generated thread HTML, messages are shown as text only, with no per-message timestamp column/field.

So:  
- **Source files may contain time info, but mostly at session level.**  
- **Per-message timestamps are not surfaced by this exporter.**

If you want, I can quickly map out where to add message-level `created/ts` handling next.

Check to see if there is a message timestamp field in there that we could potentially use.

I’ll quickly scan the local conversation export inputs for message-level keys (like `ts`/`timestamp` inside each message payload) so we can confirm whether they’re present in existing rollout/history records.

I found clear evidence in the local archived rollout JSONL: each message record has its own top-level `timestamp` alongside `type`. I’ll grab a small sample slice to show exact shape (no code edits needed).

Yes — there is a per-record timestamp field in the source data you’re reading.

From a live local Codex data file in `~/.codex/archived_sessions`, each `response_item` / `event_msg` / `session_meta` line has a top-level `timestamp` (for example: `"timestamp":"2026-03-07T19:14:41.321Z", "type":"response_item", ...`). So for messages there is a candidate time value you could use.

`history.jsonl` has a different shape: rows are objects like `{"session_id": "...", "ts": 175..., "text": "..."}` and are not structured as role+content message objects the same way.

Right now the exporter in [scripts/export_codex_conversations.py](/Users/gregb/Documents/devel/aao-mechd/scripts/export_codex_conversations.py:239) ignores those message-level times, so they aren’t rendered in thread HTML yet.

If you want, I can wire a per-message timestamp through to the thread output next.

Yes.

I’ll add message-level timestamp support to the exporter by threading timestamps through message parsing (for both rollout JSONL and history rows), then display each message timestamp in the thread HTML. I’m keeping the existing behavior intact and only extending it.

The first patch missed because the context didn’t match exactly. I’m applying smaller focused edits to the same spots to avoid unnecessary churn.

Done — we now use message-level timestamps when available.

I updated [scripts/export_codex_conversations.py](/Users/gregb/Documents/devel/aao-mechd/scripts/export_codex_conversations.py) to parse and carry per-message time fields into thread output:

- It reads top-level message `timestamp` or `ts` from rollout JSONL `response_item` records.
- It also preserves `timestamp` in legacy session JSON when present.
- It maps `history.jsonl` `ts` into message timestamps for fallback history threads.
- Thread HTML now renders each message with a timestamp line under the role.

I did not run tests in this step. If you want, I can also add a small tweak to hide the timestamp line when missing (keep rows clean for messages without times).

Just commit that file.

I’ll commit only the touched exporter file and return the commit hash so you can reference it directly.

Committed: [a3f8e1e] Add message-level timestamps to exported Codex threads on `main`.

When it looks for git commits around the samne time, it should be looking for git commits around the same time as each message, not each thread.

That change request is good. I’ll switch commit lookup to be message-time based by attaching nearby commits to each message and rendering them with each message block. I’ll keep thread-level commit context as a fallback for existing thread views.

I’ll apply a focused patch to bind commit lookup to `message["timestamp"]` where present, while keeping the existing thread-level commit list as a fallback based on thread metadata for compatibility.

I’m making one tiny robustness patch for epoch-style timestamps so message times from `history.jsonl` can still resolve to commits.

I’ve wired commit lookup to run per message timestamp. I’m staging and committing that same file now, then I’ll share the commit ID.

Implemented and committed.

The nearby-commit lookup now uses each message’s timestamp first, not just the thread timestamp.

Commit: [3e21043] Attach nearby git commits per conversation message timestamp

What changed in [scripts/export_codex_conversations.py](/Users/gregb/Documents/devel/aao-mechd/scripts/export_codex_conversations.py):
- Per-message timestamps are parsed and used in `_attach_nearby_commits`.
- Each message now gets `nearby_commits` when it has a parseable timestamp.
- Thread-level commit list is now a fallback/aggregate when message-level timestamps exist.
- The thread HTML shows commit links under each message block, and still shows thread-level commit context separately.

No tests were run in this turn.

Commit that file.

I’ll quickly verify the working tree and confirm that [scripts/export_codex_conversations.py](/Users/gregb/Documents/devel/aao-mechd/scripts/export_codex_conversations.py) is already committed on `main`.

The requested file is already committed: [3e21043] Attach nearby git commits per conversation message timestamp.

I haven’t committed the other modified files in your working tree. If you want, I can commit only those other files separately in one or more focused commits.
