name: jam-proof-table
description: At the end of a batch of agent work (several fixes, a test run, a set of tickets), return one table that ties each claim to the Jam (a jam.dev screen recording with the console and network attached) that shows it, with its status and link, and file those Jams so they can be found later. Use when the user asks "give me the jams", "which jam shows this", "what was the jam I gave you", "show proof for each", or when a run that recorded Jams finishes and the user wants the proof listed.

# jam-proof-table

Many claims in, one table out: each thing you say works or is broken, its
status, and the Jam that shows it. The user should be able to check every
claim in one click without asking "where's the Jam for this?".

To record a new Jam, use `jam-proof`. This skill names, files, checks and
reports the Jams.

## Set up the CLI

```bash
command -v jam >/dev/null || echo "jam is not installed"
export PATH="$HOME/.local/bin:$PATH"
jam auth status --json || jam auth login
```

If `jam` is not on PATH, stop and ask the user to install it from
https://jam.dev/cli, then continue. Do not install it yourself.

Exit code 3 means not signed in. With no browser (CI, a cloud agent), ask the
user to set `JAM_TOKEN` to a personal access token from
https://jam.dev/s/settings/mcp as a secret. Never write a token to a file.
`jam agent-context` prints every command and flag.

## 1. One claim, one Jam

A row is one claim: "the price no longer truncates", "sign-in works after
sign-out". Each row gets a Jam that shows that claim. When one Jam covers
several claims, give each row the time it shows up (`at 0:48`).

A claim with no Jam stays in the table as "not recorded". Never list a local
video file or screenshot path as a Jam.

## 2. Name and file every Jam

Titles are how people find Jams later. Use `<ticket or source> <what it
shows>`. A Jam that checks a fix for an earlier Jam reuses that Jam's title
with "fix check: " in front, so both show up in one search.

```bash
jam list folders --query "Release 4.2 checks" --json      # reuse it if it exists
jam create folder "Release 4.2 checks" --json             # otherwise; returns its id
jam update jam "$ID" --folder "$FOLDER_ID" --title "ENG-412 fix check: Pro price wraps"
```

`jam create folder` makes a new folder on every call, even with a name that
exists, so look first and pass the id afterwards. One folder per run.
Creating a folder can upgrade a Viewer to a Creator, which can change seat
billing; on a Viewer account, ask first.
Rename and move only the Jams this run recorded, unless asked.

## 3. Find Jams that already exist

Before recording again, look for the Jam. A run's folder is the most
reliable way to find all of its Jams:

```bash
jam list folders --query "checks" --json
jam list jams --folder "$FOLDER_ID" --json
jam list jams --created-at -P1D --json                    # created in the last day
jam list jams --query "price" --order-by createdAt --limit 20 --json
jam list jams --url "https://example.com/pricing" --json
```

`--query` is a fuzzy search, not a title filter: read each title before
using a hit. `--order-by createdAt` lists newest first, so `--limit` drops
the oldest.

"What was the Jam I gave you?" means the conversation first: search it for
`jam.dev/c/` before searching the workspace.

## 4. Check each Jam before listing it

```bash
jam get jam "$ID" --json                                  # reads back, type, duration
```

Then check it by its `type`; the other types have no video frames:

```bash
jam get frames "$ID" --at 48000 --size medium --out "$(mktemp -d)"   # video; outside the repo
jam get screenshots "$ID" --out "$(mktemp -d)"                       # screenshot
```

A replay has no frames or screenshots: check it in its events, console and
network, and mark the row unconfirmed when they cannot settle the claim.

For a video, open the frame at the moment the claim shows up; `--at` must be
below the Jam's `duration`. A blank page, a single frozen frame, or the wrong
tab is not proof. A screenshot is one still image by design: it is proof when
the claim is visible in it. When the Jam does not show the claim, record it
again with `jam-proof` and say that you did.

Some claims happen off screen: an API status, a count, a sent message. Check
those in `jam get network`, `jam get console` or `jam get user-events`, and
say in the table which part the video shows and which part the events show.

## 5. Write the table

Keep the order the work was done in. Status is the claim's, one of: works,
broken, unconfirmed (the Jam does not settle it), not recorded.

```markdown
| # | Claim | Status | Jam | Source |
|---|-------|--------|-----|--------|
| 1 | Pro price wraps on narrow cards | works | [ENG-412 fix check](https://jam.dev/c/...) | [ENG-412](...) · [original Jam](https://jam.dev/c/...) |
| 2 | Sign-in after sign-out | broken | [ENG-415 repro](https://jam.dev/c/...) | [ENG-415](...) |
```

Under the table, one line per row that is not "works", saying why.

## After

Mark each fix check as the fix of its original Jam (`markRelated` over
MCP), so the original shows a "fixed by" backlink:

```bash
jam update jam <fix check id> --mark-related "$ORIGINAL_ID" --type fixes
```

Use `--type proves` for a Jam that shows a claim rather than a fix. If the
user asked, also comment on each original Jam with the link to its fix
check.

Post the table in chat. Post it to a pull request or ticket only when the
user asks.

## Send feedback to Jam

When this skill, a Jam MCP tool, a `jam` command or a Jam doc was wrong,
stale or confusing, or worked unusually well, tell Jam. Send it yourself:
Jam's agents read it, so it needs no approval.

Call the `submitFeedback` MCP tool with `body`, `category` and `subject`.

When MCP is unavailable, use the CLI:

```bash
jam feedback "<what you were doing, what you expected, what happened, the mistake>" --category <skills|mcp|cli|docs> --subject <skill name, tool name or command>
```

- Jam surfaces only, not the user's code or other tools.
- At most once per session, and never for a slip you corrected yourself.
- No secrets, customer data, source code, stack traces or recording content.
