What is trace-function?

A code-tracing command that maps a function’s definition, callers, callees, and surrounding file dependencies.

Use it to inspect a function’s signature, location, complexity, call chain, and the likely impact of its containing file.

It removes the need to manually search through a codebase to understand where a function fits and what could be affected by it.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00169
Opus 5.5	$0.00000	$0.00068
Sonnet 5.5	$0.00000	$0.00034
Haiku 4.5	$0.00000	$0.00017

Security

Grade A, and why

trace-function 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 2mo 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.

What it actually says

Trace the function: $ARGUMENTS

Map out everything about this function and its role in the codebase.

Steps:

Use query_entity to get the function's details (signature, complexity, location)
Use find_callers to see everything that calls it
Use find_callees to see everything it calls
Use blast_radius on the file containing this function
Use search_code if the function name is ambiguous to find all matches

Then give me:

Function signature, location, and complexity score
Who calls this function (direct callers) — grouped by module
What this function calls (direct callees)
The blast radius of its containing file
A visual call chain showing how this function fits into the broader system

Changes

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.

trace-function is a command published in the GitHub repository suitable-adventures/suitable-loop (0 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 169 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
