<permissions instructions>
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.
# Escalation Requests

Commands are run outside the sandbox if they are approved by the user, or match an existing rule that allows it to run unrestricted. The command string is split into independent command segments at shell control operators, including but not limited to:

- Pipes: |
- Logical operators: &&, ||
- Command separators: ;
- Subshell boundaries: (...), $(...)

Each resulting segment is evaluated independently for sandbox restrictions and approval requirements.

Example:

git pull | tee output.txt

This is treated as two command segments:

["git", "pull"]

["tee", "output.txt"]

## How to request escalation

IMPORTANT: To request approval to execute a command that will require escalated privileges:

- Provide the `sandbox_permissions` parameter with the value `"require_escalated"`
- Include a short question asking the user if they want to allow the action in `justification` parameter. e.g. "Do you want to download and install dependencies for this project?"
- Optionally suggest a `prefix_rule` - this will be shown to the user with an option to persist the rule approval for future sessions.

If you run a command that is important to solving the user's query, but it fails because of sandboxing or with a likely sandbox-related network error (for example DNS/host resolution, registry/index access, or dependency download failure), rerun the command with "require_escalated". ALWAYS proceed to use the `justification` parameter - do not message the user before requesting approval for the command.

## When to request escalation

While commands are running inside the sandbox, here are some scenarios that will require escalation outside the sandbox:

- You need to run a command that writes to a directory that requires it (e.g. running tests that write to /var)
- You need to run a GUI app (e.g., open/xdg-open/osascript) to open browsers or files.
- If you run a command that is important to solving the user's query, but it fails because of sandboxing or with a likely sandbox-related network error (for example DNS/host resolution, registry/index access, or dependency download failure), rerun the command with `require_escalated`. ALWAYS proceed to use the `sandbox_permissions` and `justification` parameters. do not message the user before requesting approval for the command.
- You are about to take a potentially destructive action such as an `rm` or `git reset` that the user did not explicitly ask for.
- Be judicious with escalating, but if completing the user's request requires it, you should do so - don't try and circumvent approvals by using other tools.

## prefix_rule guidance

When choosing a `prefix_rule`, request one that will allow you to fulfill similar requests from the user in the future without re-requesting escalation. It should be categorical and reasonably scoped to similar capabilities. You should rarely pass the entire command into `prefix_rule`.

### Banned prefix_rules 
Avoid requesting overly broad prefixes that the user would be ill-advised to approve. For example, do not request ["python3"], ["python", "-"], or other similar prefixes.
NEVER provide a prefix_rule argument for destructive commands like rm.
NEVER provide a prefix_rule if your command uses a heredoc or herestring. 

### Examples
Good examples of prefixes:
- ["npm", "run", "dev"]
- ["gh", "pr", "check"]
- ["pytest"]
- ["cargo", "test"]

## Approved command prefixes
The following prefix rules have already been approved: - ["rsync"]
- ["./deploy_website.sh"]
- ["git", "add"]
- ["git", "commit"]
- ["make", "validate-slide-images"]
- ["rm", "-f", ".DS_Store"]

# 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.

What items are left on the to-do list?

I’m checking the project files for the current to-do list and any remaining unchecked items so we can answer from the repo rather than guess.

I found the source of truth in `TODO.md`. I’m pulling the remaining unchecked items by section so the answer is clean instead of dumping the whole file back at you.

If you want, I can turn that into a shorter “top priorities” view or rank the open items by likely critical path.

Pick the one that seems the most urgent and work on it.

I’m treating the release-gating drift item as the most urgent because it protects every other artifact from silently disagreeing. I’m reading the existing release checks and summaries first so we can extend the current pattern instead of bolting on a one-off.

I’ve confirmed there’s already a release-state gate, but it mostly checks signatures and pass/fail summaries. Next I’m looking for the gap where docs and artifact manifests can still drift even if those summaries individually look green.

The current gate already covers many engineering summaries, but it doesn’t yet prove that documentation artifacts were generated from the same release package. I’m tracing how the website and report are built so we can gate the docs side explicitly rather than infer it.

I found a real drift hole, not just a hypothetical one: the published site currently contains copied summaries like `interface_policy` and `state_policy` with an older design signature than the release gate. I’m checking whether that mismatch already exists in the source `outputs/` tree so we can close it at the right layer.

I’ve got a concrete target now: strengthen the release gate so it automatically scans signed output summaries for signature mismatches, and strengthen the site gate so the published documentation can’t carry stale signed artifacts either. If that all verifies cleanly, this looks like enough to legitimately close the “release gating” TODO rather than just nibble at it.

I’m at the editing point now. The change I’m making is a generic “signed artifact truth” layer in `check_release_state.py` and `check_site_policy.py`, plus focused regressions so we lock in the exact stale-signature bug I found.

I’m patching the gate scripts now. The goal is twofold: local release-state must catch stale signed engineering outputs, and website-smoke must catch stale published copies of those signed outputs plus the copied design report.

The code changes are in. I’m running the targeted regressions first to shake out the gate logic before I touch the TODO entry or claim closure.

The first test run found a simple miss in the new site-policy helper. I’m fixing that helper now and rerunning the focused suite before moving on to the heavier release checks.

The focused regressions are green. I’m running the real project gates now so we verify the repo’s actual outputs get resynced and the stale-signature hole is closed in practice, not just in fixtures.

The full release gate is in the heavy analysis stage now. I’m letting it run through so the actual `outputs/` tree, not just the tests, gets brought into a self-consistent signed state.

The build is still crunching through the optimized cases. I haven’t hit a failure; it’s just in the quiet part of the pipeline, so I’m polling until it reaches the downstream gating steps.

The real build is healthy so far. It has cleared the new interface/state refresh and is now finishing the render portion before it gets back to the release checks themselves.

The real gate did exactly what we wanted: it failed on the actual stale-signature problem, and it showed the issue is deeper than a missing dependency. `interface_policy` and `state_policy` are still signing only the base config instead of the released mechanical/launch-overridden design, so I’m fixing those generators next.

The signature source issue is fixed in the Makefile now, and the targeted tests are green again. I’m doing the lighter real-world verification path next: rerun the release-state script against the current outputs, rebuild the site, and then run the site smoke gate against that rebuilt publish tree.

The new gate surfaced one more real drift source: the `spacecraft_interfaces` thermal numbers in `config/telescope.yaml` no longer match the released optimized design. I’m updating those interface values to the actual released conductances so the signed interface report reflects the same design snapshot the release gate uses.

The release-state gate is now passing on the real repo outputs. I’m rebuilding the published site and running the updated site-policy gate against that rebuilt tree so we can verify the documentation side closes too.

I’ve reached the point where the repo’s own release and site gates both pass with the new checks in place. I’m marking the release-gating TODO complete and syncing the backlog/history artifacts so the dashboard reflects the real state.

I worked the release-gating item and closed it in [TODO.md](/Users/gregb/Documents/devel/aao-mechd/TODO.md#L210). The core change is in [scripts/check_release_state.py](/Users/gregb/Documents/devel/aao-mechd/scripts/check_release_state.py) and [scripts/check_site_policy.py](/Users/gregb/Documents/devel/aao-mechd/scripts/check_site_policy.py): the local release gate now scans signed output summaries/manifests for signature and pass-state drift, and the site gate now checks that published signed artifacts and the copied design report match the source release artifacts. I also updated [Makefile](/Users/gregb/Documents/devel/aao-mechd/Makefile) so `state-policy` and `interface-policy` are generated from the same released override set, and synced the released thermal/interface conductance values in [config/telescope.yaml](/Users/gregb/Documents/devel/aao-mechd/config/telescope.yaml).

Verified on the real repo state: `29` targeted tests passed, `make state-policy interface-policy` passed, the release gate passed, and the rebuilt stakeholder site passed the updated site-policy gate. I synced the backlog history in [config/todo_history.json](/Users/gregb/Documents/devel/aao-mechd/config/todo_history.json); it now shows `66` closed and `43` open.

Can you git commit your work?

I’m packaging the release-gating work into a commit now. I’ll stage the files we changed, write a focused commit message, and then I’ll share the exact commit hash back.

I checked the worktree and the changes are scoped to the gating, config sync, tests, and TODO/history updates we made. I’m staging those files and creating a single commit for the completed release-gating closure.

Committed as `ccc30b6` with message `Tighten release and site drift gating`.
