gum-profile

gum-profile is a command for coding agents from ehmo/gum. It costs 0 tokens per session (279 once invoked), scanned A, original, MIT.

A command for the Gum tool that tests or checks expression-profile files. An expression profile is a configuration file describing how expressions should be processed.

In plain words
What is it for?
Use it to validate a profile file or run its test fixtures, including an optional input file and expected-output file.
Why use it?
It catches malformed profile files and lets you compare processing results with expected output before release or in continuous integration (automated checks run for code changes).

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gum-profile scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Usage

gum profile

Parent

Subcommands

  • gum profile test - When --input is set, applies the profile to that file (optionally comparing against --golden). When --input is omitted, runs every [[tests]] fixture in the profile file through the expression pipeline and prints a ProfileFixtureResult[] JSON envelope (--format=json).
  • gum profile validate - Parse an expression-profile DSL file and report any errors. Use this in CI to catch malformed catalog profiles before release.

Flags

Flag Type Default Help
--log-format string json Log format: json|text
--log-level string info Log level: debug|info|warn|error (overrides GUM_LOG_LEVEL)
--profile string default Profile name to read/write config under

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
