description: Create, edit, comment on, share, and run human-in-the-loop iteration loops over markdown documents via Proof's web API. Use when asked to "proof", "share a doc", "create a proof doc", "comment on a document", "suggest edits", "review in proof", "iterate on this doc in proof", "HITL this doc", "sync a Proof doc to local", when a caller needs an HITL review loop over a local markdown file (e.g., ce-brainstorm, ce-ideate, or ce-plan handoff), or when given a proofeditor.ai URL. Prefer this skill for any workflow whose output is a Proof URL or that uses a Proof doc as the review surface, even when not named explicitly.

# Proof - Collaborative Markdown Editor
Proof is a collaborative document editor for humans and agents. It supports two modes:
1. **Web API** - Create and edit shared documents via HTTP (no install needed)
2. **Local Bridge** - Drive the macOS Proof app via localhost:9847
## Identity and Attribution
Every write to a Proof doc must be attributed. Two fields carry the agent's identity:
- **Machine ID (`by` on every op, `X-Agent-Id` header):** `ai:compound-engineering` — stable, lowercase-hyphenated, machine-parseable. Appears in marks, events, and the API response.
- **Display name (`name` on `POST /presence`):** `Compound Engineering` — human-readable, shown in Proof's presence chips and comment-author badges.
Set the display name once per doc session by posting to presence with the `X-Agent-Id` header; Proof binds the name to that agent ID for the session. These values are the defaults for any caller of this skill; callers running HITL review (`references/hitl-review.md`) may pass a different `identity` pair if a distinct sub-agent should own the doc. Do not use `ai:compound` or other ad-hoc variants — identity stays uniform unless a caller explicitly overrides it.
## Human-in-the-Loop Review Mode
When a caller (e.g., `ce-brainstorm`, `ce-plan`) needs to upload a local markdown doc, collect structured human feedback in Proof, and sync the final doc back to disk, load `references/hitl-review.md` for the full loop spec: invocation contract, mark classification (change / question / objection / ambiguous), idempotent ingest passes, exception-based terminal reporting, and end-sync atomic write.
## Web API (Primary for Sharing)
### Create a Shared Document
No authentication required. Returns a shareable URL with access token.
```bash
curl -X POST https://www.proofeditor.ai/share/markdown \
-H "Content-Type: application/json" \
-d '{"title":"My Doc","markdown":"# Hello\n\nContent here."}'
```
**Response format:**
```json
{
"slug": "abc123",
"tokenUrl": "https://www.proofeditor.ai/d/abc123?token=xxx",
"accessToken": "xxx",
"ownerSecret": "yyy",
"_links": {
"state": "https://www.proofeditor.ai/api/agent/abc123/state",
"ops": "https://www.proofeditor.ai/api/agent/abc123/ops"
}
}
```
Use the `tokenUrl` as the shareable link. The `_links` give you the exact API paths.
### Read a Shared Document
```bash
curl -s "https://www.proofeditor.ai/api/agent/{slug}/state" \
-H "x-share-token: <token>"
```
### Edit a Shared Document
All operations go to `POST https://www.proofeditor.ai/api/agent/{slug}/ops`
**Note:** Use the `/api/agent/{slug}/ops` path (from `_links` in create response), NOT `/api/documents/{slug}/ops`.
**Authentication for protected docs:**
- Header: `x-share-token: <token>` or `Authorization: Bearer <token>`
- Token comes from the URL parameter: `?token=xxx` or the `accessToken` from create response
- Header: `X-Agent-Id: ai:compound-engineering` (required for presence; include on ops for consistent attribution)
**Wire-format reminder.** `/api/agent/{slug}/ops` uses a top-level `type` field; `/api/agent/{slug}/edit/v2` uses an `operations` array where each entry has `op`. Do not mix — sending `op` to `/ops` returns 422.
**Every mutation requires a `baseToken`.** Read it from `/state.mutationBase.token` (or `/snapshot.mutationBase.token`) immediately before each write, and include it in the request body. On `BASE_TOKEN_REQUIRED` or `STALE_BASE`, re-read and retry once. See the baseToken recipe in `references/hitl-review.md`.
**`Idempotency-Key` header** is recommended on every mutation for safe automation retries; required when `/state.contract.idempotencyRequired` is true.
**Comment on text:**
```json
{"type": "comment.add", "quote": "text to comment on", "by": "ai:compound-engineering", "text": "Your comment here", "baseToken": "<token>"}
```
**Reply to a comment:**
```json
{"type": "comment.reply", "markId": "<id>", "by": "ai:compound-engineering", "text": "Reply text", "baseToken": "<token>"}
```
**Resolve / unresolve a comment:**
```json
{"type": "comment.resolve", "markId": "<id>", "by": "ai:compound-engineering", "baseToken": "<token>"}
{"type": "comment.unresolve", "markId": "<id>", "by": "ai:compound-engineering", "baseToken": "<token>"}
```
**Suggest a replacement (pending — user must accept/reject):**
```json
{"type": "suggestion.add", "kind": "replace", "quote": "original text", "by": "ai:compound-engineering", "content": "replacement text", "baseToken": "<token>"}
```
**Suggest and immediately apply (tracked but committed — user can reject to revert):**
```json
{"type": "suggestion.add", "kind": "replace", "quote": "original text", "by": "ai:compound-engineering", "content": "replacement text", "status": "accepted", "baseToken": "<token>"}
```
`status: "accepted"` creates the suggestion mark and commits the change in one call. The mark persists as an audit trail with per-edit attribution and a reject-to-revert affordance. Works with `kind: "insert" | "delete" | "replace"`.
**Accept or reject an existing suggestion:**
```json
{"type": "suggestion.accept", "markId": "<id>", "by": "ai:compound-engineering", "baseToken": "<token>"}
{"type": "suggestion.reject", "markId": "<id>", "by": "ai:compound-engineering", "baseToken": "<token>"}
```
`suggestion.resolve` is not supported — use accept or reject instead.
**Bulk rewrite (whole-doc replacement):**
```json
{"type": "rewrite.apply", "content": "full new markdown", "by": "ai:compound-engineering", "baseToken": "<token>"}
```
**Block-level edits via `/edit/v2`** (separate endpoint, separate shape):
```bash
curl -X POST "https://www.proofeditor.ai/api/agent/{slug}/edit/v2" \
-H "Content-Type: application/json" \
-H "x-share-token: <token>" \
-H "X-Agent-Id: ai:compound-engineering" \
-H "Idempotency-Key: <uuid>" \
-d '{
"by": "ai:compound-engineering",
"baseToken": "mt1:<token>",
"operations": [
{"op": "replace_block", "ref": "b3", "block": {"markdown": "Updated paragraph."}},
{"op": "insert_after", "ref": "b3", "block": {"markdown": "## New section"}}
]
}'
```
Supported `op` kinds inside `operations`: `replace_block`, `insert_before`, `insert_after`, `delete_block`, `replace_range` (uses `fromRef` + `toRef`), `find_replace_in_block` (takes `occurrence: "first" | "all"`). Read `/snapshot` to get stable block `ref` IDs and the `mutationBase.token`.
**Editing while a client is connected is fine.** `/edit/v2`, `suggestion.add` (including `status: "accepted"`), and all comment ops work during active collab. Only `rewrite.apply` is blocked by `LIVE_CLIENTS_PRESENT` — it would clobber in-flight Yjs edits.
**When the loop breaks.** If a mutation keeps failing after a fresh read and one retry, or state across reads looks inconsistent, call `POST https://www.proofeditor.ai/api/bridge/report_bug` with the failing request ID, slug, and raw response. The server enriches and files an issue.
### Known Limitations (Web API)
- Bridge-style endpoints (`/d/{slug}/bridge/*`) require client version headers (`x-proof-client-version`, `x-proof-client-build`, `x-proof-client-protocol`) and return 426 CLIENT_UPGRADE_REQUIRED without them. Use `/api/agent/{slug}/ops` instead.
## Local Bridge (macOS App)
Requires Proof.app running. Bridge at `http://localhost:9847`.
**Required headers:**
- `X-Agent-Id: claude` (identity for presence)
- `Content-Type: application/json`
- `X-Window-Id: <uuid>` (when multiple docs open)
### Key Endpoints
| Method | Endpoint | Purpose |
|--------|----------|---------|
| GET | `/windows` | List open documents |
| GET | `/state` | Read markdown, cursor, word count |
| GET | `/marks` | List all suggestions and comments |
| POST | `/marks/suggest-replace` | `{"quote":"old","by":"ai:compound-engineering","content":"new"}` |
| POST | `/marks/suggest-insert` | `{"quote":"after this","by":"ai:compound-engineering","content":"insert"}` |

| POST | `/rewrite` | `{"content":"full markdown","by":"ai:compound-engineering"}` |
| POST | `/presence` | `{"status":"reading","summary":"..."}` |
| GET | `/events/pending` | Poll for user actions |
### Presence Statuses
`thinking`, `reading`, `idle`, `acting`, `waiting`, `completed`
## Workflow: Review a Shared Document
When given a Proof URL like `https://www.proofeditor.ai/d/abc123?token=xxx`:
1. Extract the slug (`abc123`) and token from the URL
2. Read the document state via the API
3. Add comments or suggest edits using the ops endpoint
4. The author sees changes in real-time
```bash
# Read
curl -s "https://www.proofeditor.ai/api/agent/abc123/state" \
-H "x-share-token: xxx"
# Get baseToken for the next mutation
BASE=$(curl -s "https://www.proofeditor.ai/api/agent/abc123/state" \
-H "x-share-token: xxx" | jq -r '.mutationBase.token')
# Comment
curl -X POST "https://www.proofeditor.ai/api/agent/abc123/ops" \
-H "Content-Type: application/json" \
-H "x-share-token: xxx" \
-H "X-Agent-Id: ai:compound-engineering" \
-d "$(jq -n --arg base "$BASE" '{type:"comment.add",quote:"text",by:"ai:compound-engineering",text:"comment",baseToken:$base}')"
# Suggest edit (tracked, pending)
curl -X POST "https://www.proofeditor.ai/api/agent/abc123/ops" \
-H "Content-Type: application/json" \
-H "x-share-token: xxx" \
-H "X-Agent-Id: ai:compound-engineering" \
-d "$(jq -n --arg base "$BASE" '{type:"suggestion.add",kind:"replace",quote:"old",by:"ai:compound-engineering",content:"new",baseToken:$base}')"
# Suggest and immediately apply (tracked, committed)
curl -X POST "https://www.proofeditor.ai/api/agent/abc123/ops" \
-H "Content-Type: application/json" \
-H "x-share-token: xxx" \
-H "X-Agent-Id: ai:compound-engineering" \
-d "$(jq -n --arg base "$BASE" '{type:"suggestion.add",kind:"replace",quote:"old",by:"ai:compound-engineering",content:"new",status:"accepted",baseToken:$base}')"
```
## Workflow: Create and Share a New Document
```bash
# 1. Create
RESPONSE=$(curl -s -X POST https://www.proofeditor.ai/share/markdown \
-H "Content-Type: application/json" \
-d '{"title":"My Doc","markdown":"# Title\n\nContent here."}')
# 2. Extract URL and token
URL=$(echo "$RESPONSE" | jq -r '.tokenUrl')
SLUG=$(echo "$RESPONSE" | jq -r '.slug')
TOKEN=$(echo "$RESPONSE" | jq -r '.accessToken')
# 3. Bind display name via presence
curl -s -X POST "https://www.proofeditor.ai/api/agent/$SLUG/presence" \
-H "Content-Type: application/json" \
-H "x-share-token: $TOKEN" \
-H "X-Agent-Id: ai:compound-engineering" \
-d '{"name":"Compound Engineering","status":"reading","summary":"Uploaded doc"}'
# 4. Share the URL
echo "$URL"
# 5. Make edits using the ops endpoint (baseToken required)
BASE=$(curl -s "https://www.proofeditor.ai/api/agent/$SLUG/state" \
-H "x-share-token: $TOKEN" | jq -r '.mutationBase.token')
curl -X POST "https://www.proofeditor.ai/api/agent/$SLUG/ops" \
-H "Content-Type: application/json" \
-H "x-share-token: $TOKEN" \
-H "X-Agent-Id: ai:compound-engineering" \
-d "$(jq -n --arg base "$BASE" '{type:"comment.add",quote:"Content here",by:"ai:compound-engineering",text:"Added a note",baseToken:$base}')"
```
## Workflow: Pull a Proof Doc to Local
Sync the current Proof doc state to a local markdown file. Used by:
- HITL review end-sync (`references/hitl-review.md` Phase 5) when the doc originated from a local file
- Ad-hoc snapshots of a Proof doc to disk (before closing the tab, archiving, handing off)
- Refreshing a local working copy against the live Proof version
```bash
SLUG=<slug>
TOKEN=<accessToken>
LOCAL=<absolute-path>
# One read to a temp file — avoids passing markdown through $(...), which would strip trailing newlines.
STATE_TMP=$(mktemp)
curl -s "https://www.proofeditor.ai/api/agent/$SLUG/state" \
-H "x-share-token: $TOKEN" > "$STATE_TMP"
REVISION=$(jq -r '.revision' "$STATE_TMP")
# Atomic write: stream .markdown bytes directly to a temp sibling, then rename.
TMP="${LOCAL}.proof-sync.$$"
jq -jr '.markdown' "$STATE_TMP" > "$TMP" && mv "$TMP" "$LOCAL"
rm "$STATE_TMP"
```
`jq -jr` (`-j` no trailing newline, `-r` raw string) streams the markdown bytes straight to the temp file without going through a shell variable, so trailing newlines survive intact. `mv` within the same filesystem is atomic — a crashed write leaves the original untouched rather than a half-written file.
**Confirm before writing when the pull isn't directly asked for.** If a workflow ends up pulling as a side-effect of a different action (e.g., HITL review completion), surface the impending write with a short confirm like "Sync reviewed doc to `<localPath>`?" A silent overwrite is surprising — the user may have forgotten the local file exists in that session, or expected Proof to stay canonical until they explicitly asked to pull.
## Safety
- Use `/state` content as source of truth before editing
- During active collab use `edit/v2` (direct block changes) or `suggestion.add` (tracked changes); reserve `rewrite.apply` for no-client scenarios since it's blocked by `LIVE_CLIENTS_PRESENT` when anyone is connected
- Don't span table cells in a single replace
- Always include `by: "ai:compound-engineering"` on every op and `X-Agent-Id: ai:compound-engineering` in headers for consistent attribution
- Read a fresh `baseToken` before every mutation; on `STALE_BASE`, re-read and retry once

# HITL Review Mode
Human-in-the-loop iteration loop for a markdown document shared via Proof. Invoked either by an upstream skill (`ce-brainstorm`, `ce-ideate`, `ce-plan`) handing off a draft it produced, or directly by the user asking to iterate on an existing markdown file they already have on disk ("share this to proof and iterate", "HITL this doc with me"). Mechanics are identical in both cases: upload the local doc, let the user annotate in Proof's web UI, ingest feedback as in-thread replies and tracked edits, and sync the final doc back to disk.
This mode assumes a local markdown file exists. There is no "from scratch" entry — if the user wants a fresh doc, create one with the normal proof create workflow first, then invoke HITL.
Load this file when HITL review mode is requested — whether by an upstream caller or directly by the user.
---
## Invocation Contract
Inputs:
- **Source file path** (required): absolute or repo-relative path to the local markdown file. When an upstream caller invokes this mode, it passes the path explicitly. When the user invokes directly ("share that doc to proof and let's iterate"), derive the path from conversation context — the file the user just referenced, created, or edited. If ambiguous, ask the user which file.
- **Doc title** (required): display title for the Proof doc. Upstream callers pass this explicitly; on direct-user invocation, default to the file's H1 heading, falling back to the filename (minus extension) if no H1 exists.
- **Recommended next step** (optional, caller-specific): short string the caller wants echoed in the final terminal output (e.g., "Recommended next: `/ce-plan`"). Not used on direct-user invocation — the terminal report simply summarizes the iteration and asks what's next.
Agent identity is fixed, not a parameter: every API call uses agent ID `ai:compound-engineering` and display name `Compound Engineering`. Callers do not override this.
Return shape (used by upstream callers to resume their handoff; also shown to the user in the terminal when invoked directly):
- `status`: `proceeded` | `done_for_now` | `aborted`
- `localPath`: the source file path (same as input)
- `localSynced`: `true` if Phase 5 wrote the reviewed doc back to `localPath`; `false` if the user declined the sync and local is stale. Only present on `proceeded`.
- `docUrl`: the tokenUrl for the Proof doc
- `openThreadCount`: number of unresolved threads still in the doc
- `revision`: final doc revision after end-sync (only on `proceeded`)
---
## Phase 1: Upload and Wait
1. Read the local markdown file into memory. Remember this content as `uploadedMarkdown` — Phase 5 compares against it to detect whether anything changed during the session.
2. `POST https://www.proofeditor.ai/share/markdown` with `{title, markdown}` → capture `slug`, `accessToken`, `tokenUrl`
3. `POST /api/agent/{slug}/presence` with `X-Agent-Id: ai:compound-engineering`, `x-share-token: <token>`, body `{"name":"Compound Engineering","status":"reading","summary":"Uploaded doc for review"}`
4. Display prominently in the terminal:
```
Doc ready for review: <tokenUrl>
```
5. Ask the user with the platform's blocking question tool (`AskUserQuestion` in Claude Code, `request_user_input` in Codex, `ask_user` in Gemini). If no question tool is available, present the options in chat and wait for the reply.
**Question:** "Highlight text in Proof to leave a comment. The agent will read each one, reply in-thread or apply the fix, then sync changes back to your local file. What's next?"
**Options:**
- **I'm done with feedback — read it and apply**
- **I have no feedback — proceed**
If the user is still reviewing, they leave the prompt open — the blocking question waits naturally. A third "still working" option would be a no-op wrapper for that.
On **I have no feedback — proceed**: skip to Phase 5 (end-sync); return to caller with `status: proceeded`.
On **I'm done with feedback**: continue to Phase 2.
---
## Phase 2: Ingest Pass
A single pass over the current doc state. Deterministic, idempotent, derivable from marks — no session cache, no sidecar state.
At the start of the pass, update presence to `status: "acting"` with a short summary like `"Reading your feedback"` so anyone watching the Proof tab sees the agent is live on their comments. Update to `status: "waiting"` before the Phase 3 terminal report so the tab signals "ball is in your court" while the terminal asks for the next signal. Same `POST /presence` call as Phase 1 — just different `status`/`summary`.
### 2.1 Read fresh state
```
GET /api/agent/{slug}/state
Headers: x-share-token: <token>
```
Capture:
- `markdown` (current body — includes any user direct edits and accepted suggestions)
- `revision`
- `marks` (object keyed by markId)
- `mutationBase.token` — the baseToken required for this round's mutations
### 2.2 Identify marks that need attention
Filter `marks` to items where **all** of the following hold:
- `by` starts with `human:` (authored by a human, not the agent)
- `resolved` is `false`
- Either `thread` has no entry authored by any `ai:*` identity, **OR** the latest entry in `thread` is authored by `human:*` with an `at` timestamp newer than the latest `ai:*` entry (user responded to a prior agent reply)
Skip everything else. Agent-authored marks, resolved threads, and threads already replied to with no new human response are done.
### 2.3 Read each mark and decide how to respond
The point of HITL is to give the user a natural way to steer the doc without dragging every decision into the terminal. Most feedback can be auto-applied. Only escalate when the agent genuinely can't make a confident call alone.
Real feedback blends types — "this is wrong, rename to Y" is both objection and directive; "why X? I'd prefer Z" is both question and suggestion. Don't force a clean classification. Read the comment text, the anchored `quote`, and any prior thread replies, and decide:
**Can the agent apply a fix directly with confidence?** Imperatives ("rename X to Y", "remove this", "add a section about Z") usually qualify. Apply the edit, reply with a one-line summary of what changed, resolve.
**Is this a question with a clear answer?** Answer in-thread. Resolve if the answer stands on its own. If answering surfaces a new decision the user should weigh in on, leave open and surface it in the terminal report.
**Is this a disagreement?** ("this is wrong", "contradicts §2", "this won't work"). Evaluate the claim against current content. If the agent agrees, fix and reply "Agreed — updated to X". If the agent disagrees, reply with the reasoning and leave open. Don't silently apply an objection without evaluating it — the whole point is that the user flagged it *because* they think the plan is wrong.
**Is the intent genuinely unclear?** First try: attempt the most reasonable interpretation, apply it, and reply "I read this as X — let me know if I should revert." That's cheaper than a round-trip when stakes are low. Ask for clarification only when the interpretations lead to meaningfully different outcomes. When asking, use the platform's blocking question tool for a quick multiple-choice when the options are discrete, or leave it as an open thread comment when free-form response is more natural. Either way the thread stays open so the next pass picks up the user's reply.
**Invariant:** every attention-needing mark ends the pass with an agent reply in its thread. Unreplied = "still to do" — the next pass re-classifies it. This is what makes the loop idempotent without a sidecar: mark state *is* the state. Even when the agent disagrees or can't decide, reply (with reasoning or a question) rather than silently skip.
### 2.4 Apply edits
The user is collaborating in the doc, not waiting on approval. Every mutation works with live clients — only whole-doc `rewrite.apply` is gated. Pick the tool that matches intent:
**Default: `suggestion.add` with `status: "accepted"`** for content changes anchored on a quote (reword, rename, clarify, correct, add a sentence inline). One call creates a tracked suggestion mark *and* commits the change. The user sees committed text (no pending approval needed), and the mark persists as audit trail with per-edit attribution and a one-click reject-to-revert. This is the right primitive for HITL auto-applied edits — it gives the user a reversible trail without asking them to re-review anything.
```json
{"type":"suggestion.add","kind":"replace","quote":"<anchor>","content":"<new>","by":"ai:compound-engineering","status":"accepted","baseToken":"<token>"}
```
Use `kind: "insert" | "delete" | "replace"` as appropriate; all three support `status: "accepted"`.
**Use `/edit/v2` silently** only when the trail is actively wrong or technically blocked:
- **Atomicity is required** — multiple coordinated edits must commit together or not at all (e.g., insert new section + update a reference in another block + delete the obsolete paragraph). `/edit/v2` takes an `operations` array that commits atomically; separate `suggestion.add` calls can partially succeed.
- **Pre-user self-correction** — the agent is fixing its own output *before* the user has looked at the doc (e.g., spotted a mistake mid-ingest-pass). A tracked mark would imply "there was an old version," which is misleading from the user's perspective.
- **Pure structural insertion with no quote anchor** — adding an entirely new block/section where no existing text serves as an anchor. `suggestion.add` requires a `quote`; `/edit/v2` has `insert_before` / `insert_after` keyed on block `ref`.
- **Structural list-item or block removal** — `suggestion.add` with `kind: "delete"` only deletes the text inside a list item; the bullet marker (`*`, `-`, or numeric `1.`) stays behind as an orphan line. Use `/edit/v2 delete_block` to remove an entire block, or `find_replace_in_block` to splice out the item plus its surrounding whitespace cleanly.
```bash
# Get snapshot for block refs + baseToken
curl -s "https://www.proofeditor.ai/api/agent/{slug}/snapshot" -H "x-share-token: <token>"
# Apply
curl -X POST "https://www.proofeditor.ai/api/agent/{slug}/edit/v2" \
-H "Content-Type: application/json" -H "x-share-token: <token>" \
-H "X-Agent-Id: ai:compound-engineering" -H "Idempotency-Key: <uuid>" \
-d '{"by":"ai:compound-engineering","baseToken":"<token>","operations":[...]}'
```
Supported `op` kinds: `replace_block`, `insert_before`, `insert_after`, `delete_block`, `replace_range` (`fromRef`+`toRef`), `find_replace_in_block` (`occurrence: "first"|"all"`).
Op body shapes (block content must be wrapped in `block: {markdown}` — the server rejects flat `{op, ref, markdown}` shapes):
```json
{"op":"replace_block","ref":"b8","block":{"markdown":"new content"}}
{"op":"insert_after","ref":"b3","block":{"markdown":"new block"}}
{"op":"delete_block","ref":"b6"}
{"op":"find_replace_in_block","ref":"b4","find":"old","replace":"new","occurrence":"first"}
{"op":"replace_range","fromRef":"b2","toRef":"b5","block":{"markdown":"..."}}
```
Block `ref` values drift across revisions — always re-fetch `/snapshot` for fresh refs before each `/edit/v2` call.
**Use pending `suggestion.add` (no status)** when the change is judgment-sensitive enough that the agent wants explicit user approval before commit — rare in HITL, since the point of auto-applied edits is to reduce round-trips. Most judgment-sensitive cases are better handled by leaving the thread open with a clarifying question.
**`rewrite.apply` is not needed during a live review.** It's blocked by `LIVE_CLIENTS_PRESENT` anyway.
**Mutation requirements (every write, including replies and resolves):**
- Top-level field is `type` on `/ops`; `operations[].op` on `/edit/v2`. Do not mix.
- Include `baseToken` from `/state.mutationBase.token` (or `/snapshot.mutationBase.token` for `/edit/v2`). On `STALE_BASE` or `BASE_TOKEN_REQUIRED`, re-read and retry once.
- Set `by: "ai:compound-engineering"` and header `X-Agent-Id: ai:compound-engineering`.
- Include an `Idempotency-Key` header (fresh UUID per logical write) so retries stay safe.
- Reply: `{"type":"comment.reply","markId":"<id>","by":"ai:compound-engineering","text":"..."}`. Resolve: `{"type":"comment.resolve","markId":"<id>","by":"ai:compound-engineering"}`. Reopen if needed: `{"type":"comment.unresolve", ...}`.
**When the loop breaks.** If a mutation keeps failing after a fresh read and one retry, or two reads disagree about state, call `POST https://www.proofeditor.ai/api/bridge/report_bug` with the request ID, slug, and raw response body before falling back. Don't silently skip — that loses the audit trail the user is relying on.
---
## Phase 3: Terminal Report
Exception-based. Don't replay what the user can already see in the Proof doc — the full reasoning for each thread lives there. The terminal is for the decisions the user needs to make next.
Every report covers three things, phrased naturally for the current state:
- **What got handled** (e.g., how many comments resolved, any edits auto-applied)
- **What's still open** — if any escalations remain, each one gets one line of anchored quote plus one line of the agent's reply or question. Fuller context stays in the Proof thread
- **The doc URL** — always include it; the user may have closed the tab
Keep the whole report scannable at a glance. Three common shapes fall out of this naturally:
- A clean pass with everything handled collapses to a single line plus the doc URL
- An escalation pass lists the open threads compactly after a one-line summary of what was handled
- A pass with no new feedback just notes that and points to the doc
Phrase them in whatever voice matches the situation rather than matching a template — "handled 4, 1 still needs you" and "all 5 addressed, doc's ready" are both fine.

## Phase 4: Next-Signal Prompt
Ask the user with the platform's blocking question tool (`AskUserQuestion` in Claude Code, `request_user_input` in Codex, `ask_user` in Gemini). If no question tool is available, present the options in chat and wait for the reply.
**Question:** "Proof review pass done. What's next?"
Offer options that cover these intents — use concrete user-facing labels, not agent-internal jargon (no "end-sync", "ingest pass", etc.). Only include the options that fit the current state. Keep labels imperative and third-person (no "I'll" / "I'm" — it is ambiguous in a tool-mediated menu whether the speaker is the user or the agent) and keep the `[short label] — [description]` shape consistent across every option. A "still working, come back later" option is not offered: the blocking question already waits, so that option would be a no-op wrapper (per the Interactive Question Tool Design rules in `plugins/compound-engineering/AGENTS.md`).
- **Discuss** → `Discuss — walk through the open threads in terminal`
Talk through open threads in the terminal; the agent echoes decisions back to Proof threads. Only useful when escalations are open.
- **Proceed** → `Save — save the reviewed doc back to the local file`
Go to Phase 5 end-sync. If escalations are still open, name that in the label (e.g., `Save with 3 threads still open`) so the user is accepting the tradeoff explicitly instead of via a nested confirm.
- **Another pass** → `Re-check — look for new comments in Proof`
Re-read state and re-ingest. Worth offering even after a clean pass, since the user may have added comments while the report rendered.
- **Done for now** → `Pause — stop without saving`
Stop without syncing; return to caller with `status: done_for_now`, no end-sync.
The sync confirmation happens in Phase 5 regardless of whether threads are open — this step only asks what the user wants next, not whether to overwrite the local file.

## Phase 5: End-Sync
Runs when the user selects **Proceed**. Before prompting anything, check whether the Proof content actually diverged from what was uploaded — if not, there's nothing to sync and no reason to ask.
1. Fetch current state: `GET /api/agent/{slug}/state` with `x-share-token: <token>`. Save the full response body to a temp file (`$STATE_TMP`) so the markdown bytes can later be streamed to disk without passing through `$(...)` (which would strip trailing newlines). Extract `state.revision` from that file into `$REVISION`. Read `state.markdown` from that file for the comparison in step 2.
2. Compare `state.markdown` to `uploadedMarkdown` (captured in Phase 1).
**If identical** — no content changes happened during the session. Skip the sync prompt entirely. Display:
```
No changes to sync. Local file is unchanged.
Doc: <tokenUrl>
```
Set presence `status: completed`, summary `"Review complete, no changes"`. Return to the caller with `status: proceeded`, `localSynced: true` (local matches Proof — no write needed, local is not stale), `revision: <state.revision>`, and the rest of the standard fields.
**If different** — continue to step 3.
3. Ask with the platform's blocking question tool (`AskUserQuestion` in Claude Code, `request_user_input` in Codex, `ask_user` in Gemini). If no question tool is available, present the options in chat and wait for the reply.
**Question:** "Sync the reviewed doc back to `<localPath>`? Proof has your review changes; local still has the pre-review copy."
**Options:**
- **Yes, sync now** (default, recommended)
- **Not yet, I'll pull it later** (returns to caller with `localSynced: false`)
Why the extra prompt: the user may have started review hours ago and lost track of the local file at stake. A brief confirm makes the file write visible rather than a silent side-effect of clicking Proceed earlier. The caller signals via `localSynced` so downstream workflows can warn that local is stale.
4. On **Yes, sync now**, write the fetched markdown to local — see `Workflow: Pull a Proof Doc to Local` in `SKILL.md`:
```bash
# $STATE_TMP is the temp file holding the /state response from step 1.
TMP="${SOURCE}.proof-sync.$$"
jq -jr '.markdown' "$STATE_TMP" > "$TMP" && mv "$TMP" "$SOURCE"
rm "$STATE_TMP"
```
Stream `.markdown` bytes directly from the saved state file with `jq -jr` — do not capture the markdown into a shell variable, since `$(...)` would strip trailing newlines and corrupt the write. `$REVISION` (extracted separately in step 1) is safe to keep as a variable; it's an opaque scalar.
On **Not yet**, skip the write (still clean up `$STATE_TMP`).
5. Set presence `status: completed`, summary `"Review synced to <localPath>"` (or `"Review complete, local not updated"` if sync was declined) so the Proof UI shows the loop has finished.
6. Display one of:
Synced:
```
Doc synced to <localPath> (revision <N>).
Doc: <tokenUrl>
```
Declined:
```
Review complete. Local file kept as-is — pull from Proof when ready.
Doc: <tokenUrl>
```
7. Return to the caller with:
```
status: proceeded
localPath: <source>
localSynced: true | false
docUrl: <tokenUrl>
openThreadCount: <K>
revision: <N>
```
Do **not** delete the Proof doc. It remains the durable review record; the caller's workflow may want to link back to it.

## Recipes
### BaseToken-aware mutation
```bash
SLUG=<slug>
TOKEN=<accessToken>
AGENT_ID=ai:compound-engineering
mutate() {
local PAYLOAD="$1" # jq template without baseToken
local BASE
BASE=$(curl -s "https://www.proofeditor.ai/api/agent/$SLUG/state" \
-H "x-share-token: $TOKEN" | jq -r '.mutationBase.token')
curl -s -X POST "https://www.proofeditor.ai/api/agent/$SLUG/ops" \
-H "Content-Type: application/json" \
-H "x-share-token: $TOKEN" \
-H "X-Agent-Id: $AGENT_ID" \
-H "Idempotency-Key: $(uuidgen)" \
-d "$(jq -n --arg base "$BASE" --argjson payload "$PAYLOAD" '$payload + {baseToken: $base}')"
}
```
Every mutation sends a fresh `Idempotency-Key` so retries on network hiccups do not double-apply the op. This is required when `/state.contract.idempotencyRequired` is true and harmless otherwise.
On `STALE_BASE` in the response, re-run — the state read picks up the fresh token automatically.
### jq gotcha when inspecting responses
When extracting fields from API responses with jq's `//` alternative operator, parenthesize inside object constructors — jq parses `{markId: .markId // .result.markId}` as a syntax error. Use `{markId: (.markId // .result.markId)}`, or pull the value outside the object: `jq -r '.markId // .result.markId'`.
### Identity
All ops must include:
- `by: "ai:compound-engineering"` in the request body
- `X-Agent-Id: ai:compound-engineering` in headers (required for presence; recommended for ops for consistent attribution)
Display name `Compound Engineering` is bound via `POST /presence` with `{"name":"Compound Engineering", ...}`. Set this once after upload; it carries across subsequent ops.
