What it does
Pure Lsp Execute Parallel is an agent skill from finos/legend-engine. Runs 2 to 30 Pure functions or tests concurrently on the warm LSP daemon via pure-lsp execute-parallel, or every test in a package or .pure file with --package/--source. Use whenever more than one function or test is to be run, including several tests on one PCT adapter, and never a shell loop of pure-lsp execute. Returns per-entry status, duration and typed returnValue plus a cancellable runId. Also the way to collect the values of many value-returning functions without a runAll() aggregator. About 2x faster…
Its SKILL.md is about 930 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 Databases, covering Data warehousing. It works with Snowflake. The licence is Apache-2.0.
When your agent uses it
- More than one function
- Test is to be run
- Including several tests on one PCT adapter
- Never a shell loop of pure-lsp execute
Example prompts
- “/pure-lsp-execute-parallel”
What it can do on your machine
Read from SKILL.md and the folder at commit 00108b7. 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
Pure Lsp Execute Parallel loads about 927 tokens when it runs. Until then it costs about 152 tokens; SKILL.md has 375 words of instructions outside code blocks.
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.

- description
- Runs 2 to 30 Pure functions or tests concurrently on the warm LSP daemon via `pure-lsp execute-parallel`, or every test in a package or .pure file with --package/--source. Use whenever more than one function or test is to be run, including several tests on one PCT adapter, and never a shell loop of `pure-lsp execute`. Returns per-entry status, duration and typed returnValue plus a cancellable runId. Also the way to collect the values of many value-returning functions without a runAll() aggregator. About 2x faster than serial for five Snowflake PCT tests (51 s against 116 s).
Run many functions concurrently on one daemon
Needs a running bridge; use only the pure-lsp CLI, never curl (references/lsp-devloop-usage-rules.md). For exactly one function use pure-lsp-execute.
pure-lsp execute-parallel 'my::pkg::t1():Boolean[1]' 'my::pkg::t2():Boolean[1]' [--json]Each entry is a signature, mangled id or bare path. No <<test.Test>> annotation is needed, but there is no <<test.BeforePackage>> bracketing; name a scope instead if you need hooks. The daemon bounds the fan-out (executionConcurrency, about 0.75 x cores, in pure-lsp status). Past the core count extra threads only cost throughput, and an unbounded batch starves status/check/cancel-tests, so send the whole batch and do not chunk it. An unresolvable path fails the whole run up front, naming it. More than 30 entries is refused client-side (references/test-scopes.md).
PCT tests
One call takes one adapter, applied to every entry. Ids are <fqn>_Function_1__Boolean_1_:
P=meta::pure::functions::relation::tests::composition
pure-lsp execute-parallel "$P::testA_Function_1__Boolean_1_" "$P::testB_Function_1__Boolean_1_" --pct-adapter DuckDBFor several adapters, make one call per adapter. Adapter paths: references/pct-adapters.md.
Values, not just pass/fail
With --json, each entry in tests[] carries functionPath, status, durationMs and returnKind/returnType/returnValue/returnSize/returnTruncated, as in pure-lsp-execute. Without --json the tree shows a one-line = <value> under each entry. Use this instead of a runAll() that prints delimited output.
One parameterised function over many argument sets
A list can't name one function 30 times. The /execute-tests endpoint takes invocations: [{"path", "arguments": ["String[1]", ...], "label"}], reported by label. The CLI doesn't surface it; callers build the payload, as pure-sql-e2e does (pure-lsp-sql-e2e skill).

Edits and scopes
- Compile edited files first with a repeatable flag:
--file Main.pure --file Helper.pure. - Whole package or file, discovered server-side:
--package <pkg>or--source <file.pure>. Concurrency applies within a package node only; hooks still bracket each subtree in order.
Caveats
- Container-backed adapters (Postgres) start a Testcontainers container on first use in a session. Run one test serially first; fanning out on a cold session starts one container per entry and most fail with "Container startup failed".
- Each execution has its own console and thread-local transaction; the backend DB (server 9095, H2 9092) is shared. Concurrent writers race (
Table ... already exists). Do table setup once withpure-lsp execute, then fan out read-only tests; run tests that write serially withpure-lsp execute --package. - Parallelism does not rescue plan-gen-heavy suites, and a run holds the graph read lock throughout.
- Verified safe for relational plan-gen, graphFetch and print; for any other workload sanity-check a parallel run against a serial one first.
