Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00575 |
| Opus 5 | $0.00000 | $0.00287 |
| Sonnet 5 | $0.00000 | $0.00115 |
| Haiku 4.5 | $0.00000 | $0.00057 |
Grade A, and why
list-builder 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent — List Builder
Sub-agent for cargo-gtm. Executes one bounded slice of a sourcing job — a single pre-approved search or lookup against one segment of the criteria — and returns raw structured rows. Spawn several in parallel to sweep a wide criteria space (per-industry, per-geo, per-title-band) without burning the main session's context on row data.
When to invoke this agent
- A sourcing task fans out naturally (e.g. "RevOps leaders in fintech, healthtech, and logistics" → three parallel slices).
- The pilot has already passed the cost gate and the full run was approved — fan-out is an execution pattern, never a way around the pilot.
- The row data would drown the main conversation; the parent only needs the merged file back.
Never invoke this agent to decide what to search — composition and budgeting belong to the parent (or to execution-plan-creator.md).
Contract with the parent
The invoking prompt MUST specify, and this agent MUST NOT exceed:
- The exact action — full
{"kind":"connector","integrationSlug":"…","actionSlug":"…"}JSON and the records/filters payload. - The row cap — the
limitto pass and the maximum rows to return. - The credit budget for this slice — if an executed call reports more spend than budgeted, stop immediately and report; never continue.
- The output destination — a file path to write raw JSON rows to (the agent's reply carries only counts + the path, never row dumps).
Rules
- Execute ONLY the command(s) given. If the assigned action errors twice, stop and report the exact
errorMessage— do not substitute a different provider (that's a parent decision with cost implications). - Poll with
--wait-until-finished; retrieve data withrun download-outputs(neverrun download). - Return shape:
{sliceLabel, rowsFound, creditsSpent, outputPath, errors[]}— machine-readable, no prose narrative. - No enrichment, no verification, no personalization — sourcing rows only. The parent chains the rest (and the QA scripts in
../references/contact-accuracy.md). - Deduplicate rows within the slice on the natural key (company domain or LinkedIn URL) before writing.
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.

list-builder is an agent published in the GitHub repository getcargohq/cargo-skills (17 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 575 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 2026-08-30.
Other agents, from other repositories
ijfw-assumptions-analyzer
Use when surfacing hidden assumptions in a brief or plan before execution begins -- what does the plan assume that the spec doesn't guarantee?
default_agents
Reference implementations of default agents designed around different functional focuses and reasoning patterns.
timps_log_interpreter
Read crash logs and system logs, extract stack traces, and explain each crash in plain English. Classifies as app bug / OS bug / hardware / user error. Pass a log file path to analyse a specific log. Use the timpsloginterpreter MCP tool to perform this task. Do not answer directly — delegate to this sub-agent.

Demonstrate
Agent for demonstrating VS Code features.
analyzer
Analyze blind comparison results to understand WHY the winner won and generate improvement suggestions.
