What it does

Small Server Fit is an agent skill from FAIRY123456789/human-edge-agent-skills. Assess whether a web application and its build and runtime plan fit a low-cost Linux VPS or Alibaba Cloud ECS before purchase, implementation, or deployment. Use when choosing an OS image, Python, Node.js, or Java versions, build location, worker count, swap strategy, or minimum CPU, RAM, and disk for a repository. Produce evidence-backed FIT, FIT WITH CHANGES, NOT FIT, or NOT MEASURED decisions; do not recommend purchasing from guessed capacity.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `README.md`, `agents/openai.yaml` and `references/profile-schema.md`).

It sits in DevOps & Cloud. It works with Java, Python, Node.js and Alibaba Cloud. The repository describes itself as: 18 portable Agent Skills for voice-native AI, human judgment, microbets, social tact, writing, life systems, and safe deployment. The licence is MIT.

When your agent uses it

  • Choosing an OS image
  • Disk for a repository

Example prompts

  • “/small-server-fit”

Requirements

  • Python 3
  • Node.js

Workflow steps

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

  1. Operating-system and architecture fit: application binaries and native packages support the image and architecture.
  2. Runtime fit: an application-specific Python, Node.js, or Java runtime can be installed without replacing a system-owned runtime.
  3. Build fit: peak dependency installation and build memory and disk fit, or the build can move to a local machine or CI.
  4. Runtime memory fit: measured or bounded steady processes leave headroom for the OS, Nginx, SSH, logs, and short spikes.
  5. Persistence fit: state is outside immutable release directories and backups fit the disk or an external store.
  6. Operations fit: the service can restart, recover after reboot, expose only intended ports, and produce bounded logs.

What it can do on your machine

Read from SKILL.md and the folder at commit 31a0a16. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    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

Small Server Fit loads about 1k tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 475 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.2k

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); the scripts in this folder are not scanned.

Small Server Fit

Prevent avoidable deployment rework by checking application requirements against a measured server budget before committing to an image, runtime, or instance size.

Establish the two sides of the fit

Inspect the repository for:

  • frontend build tool and whether static assets can be built locally or in CI;
  • backend runtime and exact version constraints;
  • lockfiles, native extensions, browser binaries, machine-learning model artifacts, and serializer versions;
  • steady processes, intended worker count, background jobs, databases, uploads, logs, and temporary build space;
  • representative validation flow and concurrency expectation.

Obtain a current or candidate server profile containing OS image, architecture, vCPU, RAM, swap, disk and free space, available runtime versions, and platform services. Use references/profile-schema.md for the evidence contract.

If the host does not exist yet, mark runtime measurements NOT MEASURED and separate image compatibility from capacity claims. Do not treat a purchase date or marketing label as proof of installed runtime versions.

Make the fit decisions

Evaluate these independently:

  1. Operating-system and architecture fit: application binaries and native packages support the image and architecture.
  2. Runtime fit: an application-specific Python, Node.js, or Java runtime can be installed without replacing a system-owned runtime.
  3. Build fit: peak dependency installation and build memory and disk fit, or the build can move to a local machine or CI.
  4. Runtime memory fit: measured or bounded steady processes leave headroom for the OS, Nginx, SSH, logs, and short spikes.
  5. Persistence fit: state is outside immutable release directories and backups fit the disk or an external store.
  6. Operations fit: the service can restart, recover after reboot, expose only intended ports, and produce bounded logs.

Run scripts/evaluate_fit.py --profile <profile.json> when numeric evidence is available. The script calculates margins; it does not invent missing workload measurements.

Prefer changes in this order

  1. Build the SPA or Java artifact outside the small server.
  2. Isolate the application runtime instead of upgrading system binaries.
  3. Reduce the process or worker count when the workload and state model permit it.
  4. Move databases, object storage, or heavy build jobs to a managed or external service when justified.
  5. Add swap only as a bounded resilience measure, not as a substitute for required RAM.
  6. Increase the instance size when measured steady-state plus safety margin still does not fit.

Never recommend downgrading security, removing backups, disabling verification, or co-locating incompatible state merely to claim fit.

Output

Report each dimension as FIT, FIT WITH CHANGES, NOT FIT, or NOT MEASURED. Include:

  • the recommended OS image and runtime isolation method;
  • local or CI versus server build split;
  • process and worker budget;
  • RAM and disk arithmetic with source measurements;
  • model and native dependency compatibility risks;
  • the smallest safe next measurement or experiment;
  • a purchase recommendation only when evidence supports it.

Distinguish a confirmed fact, calculation, assumption, and recommendation. A useful result can be NOT MEASURED; false precision cannot.
