What it does

Regenerate Pgo is an agent skill from DeedleFake/trayscale. Regenerate cmd/trayscale/default.pgo by launching an isolated Trayscale, driving representative UI paths under PPROF, then replacing the profile. Use when updating PGO, collecting a CPU profile for default.pgo, refreshing profile-guided optimization, or when the user runs /regenerate-pgo.

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Go and Linux. The repository describes itself as: An unofficial GUI wrapper around the Tailscale CLI client. The licence is MIT.

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

Snapshot the tree to stdout. Section titles are This machine, Exit Nodes, Online, and Offline.
If the tree has Not Connected, skip peer pages. Still open About and Preferences.
This machine: select the hostname row if the self page is not showing (grouping 'Tailscale IPs'). Click one Tailscale IP copy button if a…
If Mullvad Exit Nodes is in the tree, select --role label --name "Mullvad Exit Nodes" --exact. Do not enable an exit node. Do not expand…
Select up to five Online peer labels and one Offline peer label, if those rows exist.
$CTRL action search-peers. If fill on the search entry fails, skip typing.
$CTRL action about, then $CTRL wait --role dialog --name About --exact --timeout 10. Do not click links.
$CTRL action preferences, then wait for dialog 'Preferences'. Do not toggle rows.
sleep 15 so the poller samples the open UI.

What it can do on your machine

Read from SKILL.md and the folder at commit 8defbe3. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- go
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Regenerate Pgo loads about 984 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 482 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~76
When it runs · the whole SKILL.md, loaded when a task matches: ~984

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: regenerate-pgo
description: Regenerate cmd/trayscale/default.pgo by launching an isolated Trayscale, driving representative UI paths under PPROF, then replacing the profile. Use when updating PGO, collecting a CPU profile for default.pgo, refreshing profile-guided optimization, or when the user runs /regenerate-pgo.

Regenerate PGO

Replace cmd/trayscale/default.pgo with a CPU profile from this checkout's binary.

Read .cursor/skills/verify-trayscale/SKILL.md first. Use control-trayscale only as the launch/drive/cleanup mechanism. Do not follow its verification recipes and do not write proof artifacts.

Run every command from the repo root:

bash

CTRL=.cursor/skills/verify-trayscale/scripts/control-trayscale
PROFILE=$(mktemp /tmp/trayscale-pgo.XXXXXX.pprof)

Keep that $PROFILE path for launch, validation, and the final copy.

Launch

control-trayscale launch copies the process environment into the isolated session. cmd/trayscale writes a CPU profile to PPROF when main returns.

bash

PPROF="$PROFILE" $CTRL launch
$CTRL doctor

Doctor requirements are the same as verify-trayscale. If doctor fails, read the run logs, run cleanup, and stop.

The live tailscaled is shared. Memory GSettings do not isolate Tailscale prefs or Taildrop.

Do not

Follow verify-trayscale forbidden actions (use_exit_node, login, change_control_server, admin_dashboard, the header connect switch, option switches). quit is required at the end and is the exception.

Also never:

activate peer.sendFile, open a send/receive file chooser, or drop files on a peer page
click Use as exit node
advertise or remove routes
switch profiles
click About Website, Report an Issue, or about.save-debug-info

Skip a coverage step whose AT-SPI handle is missing. Do not substitute a forbidden action.

Drive

Keep the process up long enough for the 5s poller to run several times.

Snapshot the tree to stdout. Section titles are This machine, Exit Nodes, Online, and Offline.
If the tree has Not Connected, skip peer pages. Still open About and Preferences.
This machine: select the hostname row if the self page is not showing (grouping 'Tailscale IPs'). Click one Tailscale IP copy button if a button is named with an address.
If Mullvad Exit Nodes is in the tree, select --role label --name "Mullvad Exit Nodes" --exact. Do not enable an exit node. Do not expand every country.
Select up to five Online peer labels and one Offline peer label, if those rows exist.
$CTRL action search-peers. If fill on the search entry fails, skip typing.
$CTRL action about, then $CTRL wait --role dialog --name About --exact --timeout 10. Do not click links.
$CTRL action preferences, then wait for dialog 'Preferences'. Do not toggle rows.
sleep 15 so the poller samples the open UI.

Tray code is unreachable on the isolated bus. Leave it uncovered.

Stop and install

The profile is complete only after pprof.StopCPUProfile runs, which happens when main returns. cleanup sends SIGTERM and skips that defer.

bash

$CTRL action quit --i-mean-it

Wait until doctor no longer reports a live window or bus_name_owned. If the process is still up after about 10s, send SIGINT to the isolated trayscale PID (the binary under the verify run dir). Do not signal by binary name.

Then:

bash

$CTRL cleanup
go tool pprof -top -nodecount=20 "$PROFILE"
cp "$PROFILE" cmd/trayscale/default.pgo
rm -f "$PROFILE"
go test -vet=all ./...

go tool pprof must print sampled functions. If it errors, the profile is truncated; leave cmd/trayscale/default.pgo unchanged.

Replace cmd/trayscale/default.pgo. Do not merge with go tool pprof -proto. Do not leave $PROFILE in the repo.

Report which coverage steps ran, which were skipped and why, and that go test -vet=all ./... passed.

Regenerate Pgo is an agent skill from DeedleFake/trayscale.pgo by launching an isolated Trayscale, driving representative UI paths under PPROF, then replacing the profile.

When should I use Regenerate Pgo?

Regenerate Pgo fits situations like: collecting a CPU profile for default.pgo; refreshing profile-guided optimization; the user runs /regenerate-pgo.

How do I install Regenerate Pgo in Claude Code?

Run `npx skills add DeedleFake/trayscale --skill regenerate-pgo -a claude-code`. Or copy the skill folder (.grok/skills/regenerate-pgo in DeedleFake/trayscale) into .claude/skills/regenerate-pgo in your project. Claude Code loads it when a task matches its description.

Can I use Regenerate Pgo in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add DeedleFake/trayscale --skill regenerate-pgo -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/regenerate-pgo, .gemini/skills/regenerate-pgo, .github/skills/regenerate-pgo and .opencode/skills/regenerate-pgo in your project.

What does Regenerate Pgo need to run?

Going by SKILL.md and its folder, Regenerate Pgo needs the command-line tools its instructions call (go).

Does Regenerate Pgo access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
