sceptre-mcp-server: Instructions file for Kiro

.kiro/steering/planning.md

sceptre-mcp-server planning.md is an instructions file for Kiro from Sceptre/sceptre-mcp-server. It costs 434 tokens per session, scanned A, original, Apache-2.0.

A planning process for complex features, architecture changes, and multi-step refactoring. It turns a request into requirements, affected files, ordered tasks, dependencies, risks, and testing points.

In plain words
What is it for?
Use it to analyze requirements, inspect the existing codebase, identify reusable parts, break work into phases, and choose an implementation order.
Why use it?
It reduces unclear work and missed prerequisites before implementation begins. A written plan also makes large changes easier to review and carry out in stages.

Instructions file for Kiro

Written for Kiro: installed under .kiro/.

This is Sceptre/sceptre-mcp-server's own configuration. It tells Kiro how to work on sceptre-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sceptre-mcp-server configures →

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

sceptre-mcp-server planning.md 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 4d 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

Planning Skill

Activate this skill when implementing complex features, architectural changes, or multi-step refactoring.

Planning Process

1. Requirements Analysis

  • Understand the feature request completely
  • Identify success criteria
  • List assumptions and constraints
  • Ask clarifying questions if anything is ambiguous

2. Architecture Review

  • Analyze existing codebase structure
  • Identify affected components and files
  • Review similar implementations for patterns to follow
  • Consider reusable code and shared utilities

3. Step Breakdown

For each step, define:

  • Clear, specific action
  • File paths and locations
  • Dependencies on other steps
  • Estimated complexity (Low/Medium/High)
  • Potential risks

4. Implementation Order

  • Prioritize by dependencies (do prerequisites first)
  • Group related changes to minimize context switching
  • Enable incremental testing at each phase

Plan Template

# Implementation Plan: [Feature Name]

## Overview
[2-3 sentence summary of what we're building and why]

## Affected Files
- [file path] — [what changes]

## Implementation Phases

### Phase 1: [Foundation]
1. [Step] (File: path/to/file)
   - Action: What to do
   - Dependencies: None / Requires step X
   - Risk: Low/Medium/High

### Phase 2: [Core Logic]
...

### Phase 3: [Integration & Polish]
...

## Testing Strategy
- Unit: [what to test]
- Integration: [what flows to test]
- E2E: [what user journeys to test]

## Risks & Mitigations
- Risk: [description] → Mitigation: [how to handle]

## Success Criteria
- [ ] [Criterion 1]
- [ ] [Criterion 2]

Rules

  • Be specific: use exact file paths, function names, variable names
  • Think about edge cases and error scenarios
  • Minimize changes: extend existing code over rewriting
  • Follow existing project conventions
  • Each step should be independently verifiable
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.
