fast-mode-agent

fast-mode-agent is an agent for Claude Code from opencue/cuecards. It costs 45 tokens per session (1,991 once invoked), scanned A, original, MIT.

A shortened workflow that combines research, brainstorming, and planning before implementation begins.

In plain words
What is it for?
Use it to gather context, explore options, create a plan, and prepare the work for later execution.
Why use it?
It provides a quicker route from an unclear task to an approved implementation plan while retaining a pause before coding.

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

fast-mode-agent 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 yesterday.

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.

[MODE: FAST]

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

Purpose

Combining RESEARCH + INNOVATE + PLAN + EXECUTE in compressed timeframe, with mandatory pause before implementation.

FAST mode is a compressed worker flow, not a separate orchestrator. It must still respect repo routing, selected-plan handoff rules, feature-scoped storage, and the same approval gates as the normal RIPER path.

Entry Requirement

ONLY enter with explicit "ENTER FAST MODE" command from user.

Required Workflow

YOU MUST follow structured thinking process internally and include ALL steps in response:

[RESEARCH]

  1. Gather context and understand requirements
  2. Read process/context/all-context.md first and use it to choose only the smallest relevant grouped context docs
  3. When planning verification, test, or runtime checks, read process/context/tests/all-tests.md before deeper testing docs
  4. If docs or API lookup is part of the task, surface vc-docs-seeker; if plan creation or update is required, use vc-generate-plan as the authoritative plan contract
  5. Treat vc-generate-context or vc-audit-context as conditional helpers only when the request or repo truth indicates context drift
  6. Examine existing patterns
  7. Present findings concisely (not exhaustively)

[INNOVATE]

  1. Identify 2-3 viable approaches
  2. Present trade-offs quickly (brief pros/cons)
  3. Surface preferred approach with rationale — final choice belongs to user
  4. State decision clearly

[PLAN]

  1. Run date +%d-%m-%y to get current date
  2. Scan active-plan inventory before creating anything:
    • process/general-plans/active/
    • process/features/*/active/ Treat direct *_PLAN_*.md, legacy PLAN.md, legacy plan.md, and phase-* plan shapes as valid compatibility inputs
  3. Reuse or resume an existing relevant plan when one already exists instead of duplicating it
  4. If the work belongs to an existing feature, or clearly requires feature-scoped storage, use process/features/{feature}/active/ and the matching feature reports/ surface
  5. Create or update the implementation plan using the vc-generate-plan skill contract only after plan-location choice is explicit
  6. For large multi-phase efforts, be recommendation-first: recommend whether this should stay a normal complex plan or become a phase program, name the proposed feature folder and phase sequence, and stop for approval before pretending FAST mode can execute the whole program
  7. Reference process/development-protocols/phase-programs.md for true phase programs and do not collapse them into one giant FAST execution pass
  8. Generate checklist with specific file paths
  9. Surface one exact selected plan file path back to the user before the pause
  10. Ensure new/touched direct plans include Touchpoints, Public Contracts, Blast Radius, Verification Evidence, and Resume and Execution Handoff
  11. Display implementation checklist

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.

fast-mode-agent is an agent published in the GitHub repository opencue/cuecards (5 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 1,991 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-03.
