Context Checkpoint

Append research process and results to the current Phase's context file.

When Called

Multiple times within a Phase, at plan-designated checkpoint points:

step: "import context-management:context-checkpoint"

Typically triggered after each strategy completes or at key decision nodes.

Hard Constraints

1. Minimum content volume: Each checkpoint append MUST contain >=500 lines of substantive markdown. This is non-negotiable. The 500 lines mean real content; inflating the count by hard-wrapping prose, padding, or repetition is gaming the constraint and is explicitly disallowed. The purpose is genuine information density for future reference.
2. Content scope: Must record both PROCESS (what was done, searched, considered) and RESULTS (what was found, decided, what remains open).
3. No mid-paragraph line breaks: Write each prose paragraph as a single continuous line. Do not insert newlines inside a paragraph to wrap it at a column width. Newlines are only for separating paragraphs, list items, headings, and fenced code blocks. (A paragraph being one long line does NOT count toward the 500-line minimum being met — write more substance, never more wrapping.)

Execution Protocol

Step 1: Ensure Context File Exists

Import context-init. This is idempotent — if the context file for the current Phase already exists, it skips creation and returns the existing file path.

Step 2: Locate Current Context File

Determine the current Phase's context file path by:

• Using the path returned by context-init, OR
• Checking context/INDEX.md for the most recent entry matching the current Phase

Step 3: Append Checkpoint Content

Append a new section to the context file:

---

## Checkpoint: <Descriptive Name>

<CC writes >=500 lines here covering process + results>

Content format: CC has full autonomy. A default semi-structured template is available as guidance but not mandatory:

---

## Checkpoint: <Descriptive Name>

### Objective
What this stage aimed to accomplish.

### Process Summary
What was done — searches performed, papers read, methods applied, decisions made along the way.

### Key Findings
The substantive results — discoveries, patterns, important papers, technical details.

### Decisions Made
Choices made during this stage and their rationale.

### Open Questions
What remains unresolved, what needs further investigation.

CC may use this template, modify it, combine sections, add new sections, or write in completely free-form style. The only requirements are:

• =500 lines of markdown

• Coverage of both process and results

Step 4: Update INDEX.md

Update the row for the current context file:

• Increment the Checkpoints count
• Update the Last Updated timestamp (run date +%Y-%m-%d-%H-%M for current time)

Content Guidance

The checkpoint is a detailed record for future reference. Write as if the reader has zero context about what happened during this research stage. Include:

• Specific searches performed (queries, databases, filters)
• Papers found and their relevance
• Methods applied and their outcomes
• Decisions made and their rationale
• Surprises, dead ends, pivots
• Quantitative results where applicable
• Open threads for future investigation

The 500-line minimum exists because sparse checkpoints are useless for recovery. Write generously — this is a research log, not a summary.

Available SOPs

Optional, no fixed order; the final leaf is always a sop.
