What it does

Tsz Project Bench is an agent skill from tsz-org/tsz. Work on TSZ benchmark and project-corpus compatibility. Use when investigating bench.yml failures, project compile guard rows, benchmark dashboard data, PGO bench setup, fixture metadata drift, or real-project blockers such as utility-types, ts-toolbelt, ts-essentials, rxjs, type-fest, zod, kysely, Next, or Vite.

Its SKILL.md is about 530 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 Frontend & Design, covering Forms and validation. It works with Vite, RxJS and Zod. The repository describes itself as: An experiment in fully hand-off software engineering: A performance-first TypeScript checker. The licence is Apache-2.0.

When your agent uses it

Investigating bench.yml failures
Project compile guard rows
Benchmark dashboard data
PGO bench setup

Example prompts

“/tsz-project-bench”

Workflow steps

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

Identify row, phase, and first failure: prepare, tsc validation, tsz check,
Required/canary/all set: TSZ_PROJECT_COMPILE_SET=.
Reproduce with the narrowest filter.
If typecheck fails, reduce to owning compiler operation before optimizing.
For speed work, name repeated operation and complexity change. No

What it can do on your machine

Read from SKILL.md and the folder at commit 153b25a. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
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

Tsz Project Bench loads about 533 tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 149 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~83
When it runs · the whole SKILL.md, loaded when a task matches: ~533

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.

TSZ Project Bench

Use for project-corpus rows, benchmark harness, fixture metadata, PGO bench setup, and website benchmark data.

Rules

Read AGENTS.md and docs/plan/ROADMAP.md for durable benchmark/project work.
Inspect overlapping PRs/issues.
Red row = correctness blocker before speed problem unless failure is runtime, residency, timeout, or OOM.
Keep fixture metadata shared across project-fixtures.sh, bench-vs-tsgo.sh, and project-compile-guard.sh.
Wrap long/heavy local commands with scripts/safe-run.sh.

Sources

scripts/bench/project-fixtures.sh
scripts/bench/bench-vs-tsgo.sh
scripts/ci/project-compile-guard.sh
crates/tsz-website/src/_data/benchmark_data.js
.github/workflows/bench.yml

Workflow

Identify row, phase, and first failure: prepare, tsc validation, tsz check, emit scope, crash, timeout, OOM, metadata, website ingestion, timing.
Required/canary/all set: TSZ_PROJECT_COMPILE_SET=<required|canary|all>.
Reproduce with the narrowest filter.
If typecheck fails, reduce to owning compiler operation before optimizing.
For speed work, name repeated operation and complexity change. No fixture-name special cases.

Commands

bash

./scripts/bench/bench-vs-tsgo.sh --prepare-only
./scripts/bench/bench-vs-tsgo.sh --quick --filter "<row>" --json-file /tmp/bench.json
TSZ_PROJECT_COMPILE_FILTER="<row>" TSZ_PROJECT_COMPILE_SET=required scripts/ci/project-compile-guard.sh
TSZ_PROJECT_COMPILE_ALLOW_FAILURES=1 TSZ_PROJECT_COMPILE_SET=all scripts/ci/project-compile-guard.sh

PR notes: goal (green, fast, or grow), row, before/after failure class, first broken phase, owner layer, fixture metadata changes, whether timing is meaningful, commands/CI links.
