What it does

Tailing Build Output is an agent skill from spencerpauly/awesome-cursor-skills. Monitor a build process (webpack, turbo, docker) for warnings and errors as they stream. Summarize issues and fix them before the build finishes.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Containers. It works with Docker and webpack. The repository describes itself as: A curated list of awesome skills for Cursor. The licence is CC0-1.0.

When your agent uses it

  • Tasks that involve Containers

Example prompts

  • “/tailing-build-output”

Requirements

  • Docker

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Start or Find the Build
  2. Poll for Output
  3. Fix Errors in Flight
  4. Summary Report

What it can do on your machine

Read from SKILL.md and the folder at commit 99cd265. 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:

    • turbo
    • npm
    • pnpm
    • docker

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, pnpm and docker, which can reach the network depending on how they are called.

    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

Tailing Build Output loads about 524 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 235 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~524

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.

Tailing Build Output

Watch a build process in real time via terminal files and fix issues as they appear.

Workflow

1. Start or Find the Build

Either start the build yourself or find the terminal running it:

bash
head -n 10 <terminals_folder>/*.txt

Look for commands like npm run build, pnpm build, turbo build, docker build, tsc, vite build.

2. Poll for Output

Read the terminal file periodically. Look for:

Errors (fix immediately):

  • ERROR / Error: / error TS
  • Module not found / Cannot find module
  • SyntaxError / TypeError
  • Failed to compile

Warnings (collect for summary):

  • WARNING / Warning: / warn
  • Deprecation / deprecated
  • Unused imports/variables
  • Large bundle size warnings (asset size limit)

Progress indicators:

  • Webpack: [XX%], modules, chunks
  • Turbo: task completion logs
  • Docker: Step X/Y
  • TypeScript: file count
3. Fix Errors in Flight

When an error appears:

  1. Extract the file path and line number from the error
  2. Read and fix the source file
  3. If the build supports watch mode, it will re-trigger automatically
  4. If not, note the fix and let the build continue — it may reveal more errors
4. Summary Report

After the build completes (check for exit_code in terminal footer):

Build Summary:
  Status: Failed (exit code 1) / Succeeded
  Duration: ~45s
  Errors fixed: 3
  Remaining warnings: 2
    - Large bundle: src/pages/Dashboard.tsx (450kb)
    - Deprecated API: useRouter from 'next/router'

Tips

  • Don't fix warnings during the build — collect them and address after
  • For turbo build, errors may appear in parallel task output — check all task logs
  • Docker builds cache layers — if you fix a file early in the Dockerfile, later layers rerun
  • TypeScript's --noEmit is useful for type-checking without a full build
