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

agtx-execute 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 9d 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

Execution Phase

You are in the execution phase of an agtx-managed task.

Input

The argument to this command is a task ID.

If .agtx/plan.md exists in the current working directory, read it — it already contains the approved plan and all needed context. Do NOT call get_task.

If .agtx/plan.md does not exist, fetch the task description:

mcp__agtx__get_task(task_id: "<the id passed to this command>")

Instructions

  1. Read .agtx/plan.md if it exists (skip get_task), otherwise fetch via get_task
  2. Implement the changes
  3. Run relevant tests to verify your changes
  4. Fix any issues found during testing

Output

When implementation is complete, write a summary to .agtx/execute.md in the current working directory with these sections:

Changes

What files were modified/created and what was changed in each.

Testing

How you verified the changes — tests run, results, manual checks.

CRITICAL: Stop After Writing

After writing .agtx/execute.md (in the current working directory):

  • Do NOT start new work beyond the plan
  • Say: "Implementation complete. Summary written to .agtx/execute.md."
  • Wait for further instructions

Output Style

Terse. No pleasantries. Fragments OK. Short synonyms. Code exact. Status updates: one line. Pattern: [what] [why]. Done.

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.
