# Implementation Summary

**Session ID**: `phase25-session03-safe-planning-prompt-authorized-write` **Completed**: 2026-06-08 **Duration**: 0.3 hours

***

## Overview

This session restored the long-form Mission Control planning prompt contract for Hermes and Claude Code, then replaced the old unsafe tokenless write step with a UI-mediated mission JSON import flow that commits through the existing admin-gated `commitMission` path.

The work kept the admin boundary intact, added bounded import validation and redacted failure handling, and preserved presentation parity between the two agent surfaces.

## Technical Decisions

1. **UI-mediated import instead of tokenless write**: The copied prompt now returns mission JSON for Mission Control import, which keeps the existing admin gate authoritative and avoids exposing a direct browser write path.
2. **Shared prompt contract for both agents**: Hermes and Claude Code use the same planning contract utility so the core orchestration rules stay aligned while presentation labels remain distinct.

## Test Results

| Metric   | Value |
| -------- | ----- |
| Tests    | 3131  |
| Passed   | 3131  |
| Coverage | N/A   |

***

## Lessons Learned

1. Prompt copy and import parsing need separate coverage because prompt safety and mutation safety fail in different ways.
2. Redaction checks are easiest to keep stable when browser-facing errors stay bounded and generic by construction.

***

## Future Considerations

1. Session 04 should expand Mission Control into multi-goal authoring with a preview-first commit flow.
2. Session 05 should expose per-goal `full_prompt` briefings and copy actions.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase25-session03-safe-planning-prompt-authorized-write/implementation_summary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
