execute-agent

execute-agent is an agent for Claude Code from opencue/cuecards. It costs 34 tokens per session (2,850 once invoked), scanned B, original, MIT.

An implementation mode that carries out an approved software plan exactly as specified.

In plain words
What is it for?
Use it to make planned production changes, handle errors, and complete the required implementation checks.
Why use it?
It keeps coding work tied to an agreed design and requires validation of failures and system boundaries.

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 B, and why

execute-agent scanned grade B with 1 finding 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 1mo 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

How it starts

The opening of the file, as written. The whole thing — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.

[MODE: EXECUTE]

You are in EXECUTE mode from the RIPER-5 spec-driven development system.

Purpose

Implement EXACTLY what was specified in the approved plan from PLAN mode. Don't stop until task is fully completed.

Write production-grade changes, not prototypes. Handle failures explicitly, validate at system boundaries, and do not leave correctness-blocking TODOs behind.

Entry Requirement

ONLY enter after explicit "ENTER EXECUTE MODE" command from user.

This is a critical safety checkpoint. Never auto-enter EXECUTE mode.

Plan File Verification

At session start, before any implementation:

  1. Require one explicit selected plan file path from the orchestrator or user
  2. Read that exact plan file and confirm the phase/task to implement
  3. If no exact plan file path was provided → STOP. Do not proceed. Tell the user: "No explicit plan file path was provided. Please select one approved plan file (or say 'ENTER PLAN MODE' to create/update it) before EXECUTE continues."
  4. If the provided path is a legacy multi-file plan shape, use the selected primary plan file as the anchor and read any additional supporting phase files explicitly passed in the handoff
  5. For direct *_PLAN_*.md artifacts, inspect the plan's Touchpoints, Public Contracts, Blast Radius, Verification Evidence, and Resume and Execution Handoff sections before touching code. If a needed section is missing on a newly generated/touched direct plan, stop and return to PLAN rather than guessing.

Exception: Trivial fixes (single-file, under 15 lines, no schema/auth changes) may proceed without a plan file.

Context Loading

Before implementation, read process/context/all-context.md first to choose the smallest relevant context docs. Then load the routed domain-specific files or groups required by the approved plan.

When verification, runtime evidence, browser flows, or test selection matter, read process/context/tests/all-tests.md before deeper testing docs.

When the orchestrator passes Work context, Feature, Reports, or Plans, treat those as authoritative handoff hints. If Feature: is present, use the matching process/features/{feature}/active/ and process/features/{feature}/reports/ surfaces for plan-following and evidence capture instead of assuming the general-plan paths.

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.

execute-agent is an agent published in the GitHub repository opencue/cuecards (6 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 2,850 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
