Continuous scanner CI not detected

This plugin remains listed. Its overall trust score is reduced by 10% because security checks are not maintained in the source repository's CI.

Optional: maintain the scanner in the source repository's CI to receive the full trust score. Listing does not require that change.

README badge not detected

Plugin owners can add the HOL badge to the repository README from Guard Plugins. Distribution, not security evidence. It adds a 2% engagement adjustment to the overall trust score and never changes the security result.

Did setup work in Claude Code?

No setup reports for Claude Code yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.

Attested installs: Fewer than 10 attested installs of this plugin in week 2026-W44, so no number is shown. Counted from opt-in HOL Guard install reports, once per machine and runtime, and never mixed with the answers above. How install reports work.

Skills

13 SKILL.md files ship with this plugin. Preview, copy, or download each one, then install them with the Skills CLI.

skills-cli

add-voiceover
skills/add-voiceover/SKILL.md
Add a spoken voiceover to a video: write the script for the ear, voice it line by line with ElevenLabs, Kokoro (a free local model) or your own text-to-speech command, and lay each line under the moment it describes, with a subtitle file. Use when the user asks to add narration, a voiceover, a voice or text-to-speech to a screen recording, demo video or walkthrough, to re-voice a video with another voice, or asks why a generated voiceover sounds robotic, echoes or drifts out of sync.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-annotate
skills/jam-annotate/SKILL.md
Turn a screenshot into a Jam (a shareable jam.dev screenshot with context attached) that points at the problem, with boxes, arrows, notes, redactions and blurs drawn by `jam create jam`. Use when the user asks to file or share an annotated screenshot as a Jam. Local annotation or redaction requests alone do not call for this skill.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-fix
skills/jam-fix/SKILL.md
Find the root cause of a bug from a Jam (a jam.dev screen recording with the console, network and user actions attached), and fix it when the user asks. Without that ask it diagnoses only, with no code changes. Read the recording's diagnostics and visual evidence, then return a diagnosis with evidence. Use when the user pastes a jam.dev link or Jam id and asks to fix, debug, triage or investigate it, or asks what went wrong in a recording.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-proof-table
skills/jam-proof-table/SKILL.md
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.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-proof
skills/jam-proof/SKILL.md
Record work you can see on screen with `jam record` and publish it as a Jam link (a shareable jam.dev recording with the console and network attached). Use when the user asks for a recorded Jam, a shareable demo, or video proof of work in a browser or desktop app. A request to verify a change or give sign-off alone does not call for recording or uploading.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-setup
skills/jam-setup/SKILL.md
Set up Jam (jam.dev screen recordings and screenshots with the console, network and user actions attached) for this coding agent in one run, in order - install the Jam CLI, sign in, connect Jam MCP, install the Jam skills, then check everything with `jam doctor`. Use when the user says "set up jam", "install jam", "connect jam to claude/cursor/codex", "jam isn't working", or a Jam skill stopped because the CLI, sign-in or MCP was missing.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-to-e2e
skills/jam-to-e2e/SKILL.md
Turn a Jam (a jam.dev screen recording with the console, network and user actions attached) into steps and an end-to-end test in the project's own runner and language, with first-class guidance for Playwright and tester-army/e2e, grounded in the current code. A Jam of a flow or demo becomes a test that guards it; a Jam of a bug becomes a failing test the fix turns green. Use when the user pastes a jam.dev link and asks for an e2e test, a regression test, a repro, or to "write a test for this".
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-to-tasks
skills/jam-to-tasks/SKILL.md
Turn a narrated Jam (a jam.dev screen recording with the speaker's transcript, console, network and user actions attached) into a numbered list of every change the person asked for, each tied to the moment, the frame and the words it came from, then work through the list. Use when the user pastes a jam.dev link and says "do what I said in this", "consume this jam", "make it look like this", or shares a feedback, walkthrough or reference recording rather than a single bug.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam-to-ticket
skills/jam-to-ticket/SKILL.md
File a Jam (a jam.dev screen recording with the console, network and user actions attached) as an issue in the team's tracker, such as Linear, GitHub Issues or Jira, with the link, repro steps, the key frame and the errors, after checking it was not filed already. Use when the user says "make a ticket for this jam", "file this jam as a bug", "put this jam in Linear", "open an issue for this recording", or asks whether a Jam was ever ticketed.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
jam
skills/jam/SKILL.md
Route a Jam (a jam.dev screen recording or screenshot with the console, network and user actions attached) to the right Jam skill. Use when the user shares a jam.dev link with no clear ask ("look at this jam", a bare link), or types /jam. For a clear ask (fix, test, ticket, record, annotate), use that skill directly.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
record-demo
skills/record-demo/SKILL.md
Record a narrated, human-paced demo video of a web feature with agent-browser: a smooth pointer, typing a viewer can read, no dead air, clicks paced to land on the narration, and a camera directed shot by shot from a screenplay, as a sharp 2560x1440 60 fps MP4. Use when the user asks to demo a feature, record a walkthrough, make a demo or screen recording for a PR, docs or release notes, or show someone what changed in the UI.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
record-terminal-proof
skills/record-terminal-proof/SKILL.md
Record a terminal run with asciinema and render it to a GIF that plays inline on GitHub, plus an MP4 when one is needed. Use when the user asks for terminal proof, a recording of a CLI run, migration, build or test command, a GIF of what the command did, or terminal output to attach to a PR.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
video-to-jam
skills/video-to-jam/SKILL.md
Turn a video file someone already has (an MP4, a Loom download, a long call or screen recording) into Jams (shareable jam.dev recordings with a transcript), one per issue, cut where the speaker moves to a new problem, each titled and filed in a folder. Use when the user says "upload these to jam", "turn this recording into jams", "split this video by bug", "make these jams instead of mp4s", or has a recording too long for one Jam.
Raw SKILL.md
SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
