Stata AI Skill

Stata AI Skill

Requires Apple Silicon macOS or Windows, the native stata-ai-skill executable, and a locally installed/licensed Stata. Intel Mac is not supported. If automatic Stata discovery fails, use the agent-guided two-stage aiskill setup fallback on the same localhost service port.

This native service is extracted from ZihaoVistonWang/stata-all-in-one and preserves the AI Skill HTTP workflow without requiring VS Code at runtime.

Use the native localhost service at http://127.0.0.1:19522 to run Stata. Do not import internal modules. The stable interface is HTTP.

Locate The Executable

Agents must resolve the executable from this skill directory before using PATH or build outputs. Do not require the user to know Cargo's target/release directory.

Expected packaged layout:

stata-ai-skill/
  SKILL.md
  bin/
    macos/
      stata-ai-skill            (legacy fallback)
    macos-arm64/
      stata-ai-skill            (Apple Silicon)
    windows/
      stata-ai-skill.exe          (x64)
    windows-arm64/
      stata-ai-skill.exe          (ARM64)
  scripts/
    discover_stata_windows.bat
  stata/
    aiskill/
      aiskill.ado
      aiskill.sthlp
      aiskill.pkg
      stata.toc

Resolution order:

1. If STATA_AI_SKILL_BIN is set, use that exact executable path.
2. macOS Apple Silicon: use <this-skill-directory>/bin/macos-arm64/stata-ai-skill.
3. macOS Intel (x86_64): stop and tell the user this skill does not support Intel Mac.
4. macOS Apple Silicon fallback: use <this-skill-directory>/bin/macos/stata-ai-skill.
5. Windows x64: use <this-skill-directory>\bin\windows\stata-ai-skill.exe.
6. Windows ARM64: use <this-skill-directory>\bin\windows-arm64\stata-ai-skill.exe.
7. Fallback only if packaged binary is missing on a supported platform: use stata-ai-skill from PATH.

To detect macOS architecture:

case "$(uname -m)" in
  arm64) exe="./bin/macos-arm64/stata-ai-skill" ;;
  x86_64)
    echo "Stata AI Skill does not support Intel Mac."
    exit 1
    ;;
  *) exe="./bin/macos/stata-ai-skill" ;;
esac

To detect Windows architecture from PowerShell:

if ($env:PROCESSOR_ARCHITECTURE -eq "ARM64") {
    $exe = ".\bin\windows-arm64\stata-ai-skill.exe"
} else {
    $exe = ".\bin\windows\stata-ai-skill.exe"
}

For development builds, refresh the packaged executable with:

cargo run -p xtask -- dist

When writing commands below, replace stata-ai-skill with the resolved executable path. Examples:

# macOS, from the skill directory
./bin/macos-arm64/stata-ai-skill serve

# Windows, from the skill directory
.\bin\windows\stata-ai-skill.exe serve

Agent Workflow

Reset And Reconfigure

Interpret requests such as "reconfigure this Skill", "reset the Stata Skill", "重新配置该技能", "重置 Stata 配置", "换一个 Stata", or "start setup over" as an explicit request to delete the persisted Stata AI Skill configuration and run setup again. The request itself authorizes this reset; do not ask for another confirmation.

If the service is online, reset it in place:

curl -s -X POST http://127.0.0.1:19522/configure/reset

This removes the persisted config file and returns restartRequired: true. Wait for the service to stop, then restart it with the resolved executable and no --stata-path argument. Stopping the process safely closes the embedded Stata session and clears install/setup tokens and phases. It does not uninstall Stata, delete ado packages, or alter the Stata license.

If the service is offline, use the resolved executable and then start it:

stata-ai-skill config reset
stata-ai-skill serve

After restarting, read /status and follow the ordinary setup flow below. A detected candidate must be shown to the user for explicit selection even when there is only one; no candidate enters the manual two-stage flow. If reset returns HTTP 409 because Stata is busy, wait for the current execution to finish and retry once. Do not use aiskill setup, force as a substitute because it leaves the old persisted selection in place.

1. Check whether the service is running:

curl -s --connect-timeout 2 http://127.0.0.1:19522/status 2>/dev/null || echo "OFFLINE"

2. If offline, start the native executable:

stata-ai-skill serve

Use the resolved executable path from "Locate The Executable"; the bare command above is only shorthand. Run the service as a long-lived background process so the agent can continue issuing HTTP requests. On macOS/zsh:

nohup ./bin/macos-arm64/stata-ai-skill serve > /tmp/stata-ai-skill.log 2>&1 &

If startup fails because the port is already in use, first recheck /status. If another Stata AI Skill service is already responding, reuse it. Otherwise choose another port and persist it:

./bin/macos-arm64/stata-ai-skill config set --port 19523
nohup ./bin/macos-arm64/stata-ai-skill serve > /tmp/stata-ai-skill.log 2>&1 &
curl -s http://127.0.0.1:19523/status

3. Read setup.phase before attempting execution. The setup states and required agent actions are:

Confirm An Automatically Detected Installation

detectedCandidates is sorted by newest Stata version, then MP, SE, BE, and IC. Even when there is only one candidate, do not select it silently. Use the host agent's best structured question tool to show the recommended candidate, other candidates, and a manual-setup choice. If no structured question tool is available, ask in chat and wait for an explicit reply.

If the user chooses manual setup, treat that selection as the complete choice: call POST /setup/install-session immediately and show its returned command. Do not ask a second question about installing aiskill.

After confirmation, configure and initialize through the already running service; no restart is needed:

curl -s -X POST http://127.0.0.1:19522/configure \
  -H "Content-Type: application/json" \
  -d '{"stataPath":"/Applications/StataNow/StataMP.app"}'

Use the selected candidate's path exactly. A successful response returns the updated status with sessionActive: true and setup.phase: "ready".

Manual Two-Stage aiskill setup

Use this when automatic discovery finds no candidates or the user explicitly chooses manual setup. That choice already starts the manual workflow; do not ask for a second installation confirmation. Immediately create an installation session:

curl -s -X POST http://127.0.0.1:19522/setup/install-session

Copy or display the returned command exactly. It contains the absolute path of the generated script, for example:

do "D:/path/to/the/system/temp/directory/installation.do"

Tell the user to run this command in the specific GUI Stata installation they want the Skill to use. The command runs net install inside that Stata process, so Stata itself selects the correct PERSONAL/PLUS ado directory for that user; the agent and background service must not guess or write the ado path directly.

The 19522 service remains alive in awaiting_install_result and receives the script's success or failure callback at GET /installed. Poll JSON /status in the background; do not issue the second command until the phase becomes awaiting_aiskill_setup. Then ask the user to run this in the same separately opened GUI Stata:

aiskill setup

Never run aiskill setup through /execute. It obtains a one-time token from GET /status?format=stata, reports the GUI Stata platform, version, edition, machine type, and c(sysdir_stata) to GET /setup, and returns immediately. Continue polling JSON /status until ready or configuration_failed.

Setup/install tokens are single-use and expire after ten minutes. Ordinary JSON /status polling does not rotate or invalidate the Stata setup token.

4. If /status returns sessionActive: true and setup.phase: "ready", call /execute.

/status includes diagnostic fields agents should use for troubleshooting:

• config.port
• config.stataPath
• config.configFile
• config.logDir
• config.tempDir
• config.graphDir
• capabilities.cwd
• capabilities.timeoutMaxSeconds

If /status returns needsLicense: true or missing: "stata_license", Stata was found but the license file was not found. Tell the user:

"Stata is installed, but the service cannot find the Stata license file stata.lic / STATA.lic. Please open Stata once to confirm it is licensed, or check that the license file exists in the Stata installation folder."

Common license locations:

• macOS: /Applications/StataNow/stata.lic
• Windows: C:\Program Files\Stata18\STATA.lic

Execute

Read Command Help First

Before using a specific Stata command, first run help <command> through /execute and read its documentation. Confirm the command syntax, options, and version-specific behavior before composing the final analysis command. For example, run help regress before using regress.

If Stata reports that the help file or command is unavailable, do not guess its syntax. Report the missing command and request approval before installing any community-contributed package.

Run Existing Do-Files Directly

When the user provides an existing .do file, pass its path in the file field. Prefer this over copying the file, reading it with Python or shell commands, or sending its contents through code.

• Use file for an existing .do file and code for inline Stata commands.
• Use an absolute file path whenever possible. Paths containing spaces are supported; JSON-encode the path normally and do not copy it to /tmp.
• Set cwd to the do-file's project directory when it uses relative paths for datasets, included do-files, logs, or generated output.
• The file must be accessible to the local Stata AI Skill service process.
• Do not send both file and code; if both are present, file takes precedence.

macOS And Linux

Use curl from bash or zsh:

curl -s -X POST http://127.0.0.1:19522/execute \
  -H "Content-Type: application/json" \
  -d '{"file":"/Users/me/project/analysis.do","cwd":"/Users/me/project","timeout":120}'

Windows Command Prompt

Windows supports both Command Prompt (cmd.exe) and PowerShell; PowerShell is not required. From Command Prompt, escape the JSON double quotes:

curl.exe -s -X POST http://127.0.0.1:19522/execute -H "Content-Type: application/json" -d "{\"file\":\"C:\\Users\\me\\project\\analysis.do\",\"cwd\":\"C:\\Users\\me\\project\",\"timeout\":120}"

Windows PowerShell

Write the request JSON, not the do-file, to a temporary UTF-8 file without a BOM, then send it with curl.exe:

$body = '{"file":"C:\\Users\\me\\project\\analysis.do","cwd":"C:\\Users\\me\\project","timeout":120}'
[System.IO.File]::WriteAllText("$env:TEMP\stata_body.json", $body, [System.Text.UTF8Encoding]::new($false))
curl.exe -s -X POST http://127.0.0.1:19522/execute `
  -H "Content-Type: application/json" `
  --data-binary "@$env:TEMP\stata_body.json"

In all three cases, the service executes the do-file directly and applies cwd before the do command.

For additional PowerShell quoting, UTF-8 BOM, and multiline JSON guidance, read references/windows-powershell-http.md when the active shell is Windows PowerShell.

Response:

{
  "success": true,
  "returnCode": 0,
  "output": "4",
  "error": "",
  "graphs": []
}

For long commands, set timeout in seconds:

curl -s -X POST http://127.0.0.1:19522/execute \
  -H "Content-Type: application/json" \
  -d '{"code":"bootstrap r(mean), reps(1000): summarize price", "timeout": 300}'

For workflows that use relative paths, set cwd. The service prepends a Stata cd command before running inline code or a do-file:

curl -s -X POST http://127.0.0.1:19522/execute \
  -H "Content-Type: application/json" \
  -d '{"cwd":"/Users/me/project","code":"use data/auto.dta, clear\nsummarize"}'

Timeout Recovery

A timeout returns HTTP 408 and sends a Stata break signal. If the response says Stata is still stopping, /status.busy deliberately remains true; do not send another execution until it becomes false. Send /break again if needed, or call /shutdown and restart the service if Stata never finishes stopping.

Graph Export

The standalone service enables Stata graph capture with quietly _gr_list on after session initialization. It recognizes graph export at its original position, including leading ., quietly/qui, capture/cap, and noisily/noi prefixes. It preserves replace and name(...); bitmap width(...) and height(...) control the Rust-rendered output dimensions.

Explicit SVG exports are executed safely and returned in the response graphs array:

[{ "name": "Graph", "svg": "/absolute/path/to/foo.svg", "png": null }]

PNG/JPG/JPEG exports are supported without asking Stata to write those formats directly. At the same point in the user's code, the service exports SVG first, then converts it with bundled Rust libraries, keeps the SVG path, and writes the requested bitmap path. For PNG requests, the png field contains the generated PNG path. For JPG/JPEG requests, png remains null and the graph object includes file and format fields for the generated bitmap. Other unsafe bitmap formats such as TIF and TIFF are still rewritten to SVG and reported in output.

If user code does not contain an explicit graph export, successful executions keep the automatic _gr_list SVG export behavior and return generated SVG paths under graphs.

Lianxh Search

When the user asks for Stata cookbook examples, command tutorials, or Lianxh articles, read and follow references/lianxh-search.md. It contains the installation-consent boundary, three-query limit, search syntax, and timeout recovery workflow.

Break And Shutdown

Interrupt the current Stata execution:

curl -s -X POST http://127.0.0.1:19522/break

Close the background service:

curl -s -X POST http://127.0.0.1:19522/shutdown

Files

The service uses system directories only. It does not create .stata-all-in-one/ in the current repository or working directory. Temporary .do files are unique and deleted after execution. Graphs are first exported as SVG and returned as absolute paths in graphs; explicit PNG/JPG/JPEG requests are converted from that SVG without requiring a system image converter.
