Context Sizing Behavior

Priority	Token Count	Action
HIGH	≤1500	Copy to `.context/session/ctx/`, inline in baseline
HIGH	>1500, ≤25K	Copy to `.context/session/ctx/`, summarize directly
HIGH	>25K	Copy to `.context/session/ctx/`, summarize via sub-agent
MEDIUM	≤2500	Copy to `.context/session/ctx/`, inline in baseline
MEDIUM	>2500, ≤25K	Copy to `.context/session/ctx/`, summarize directly
MEDIUM	>25K	Copy to `.context/session/ctx/`, summarize via sub-agent
LOW	any	Reference only (path to `.context/session/in/`, no copy)

Token estimation: tokens ≈ words / 0.75 (using wc -w)

25K limit: Files exceeding this use summarize-for-context sub-agent with chunked reads.

Baseline Template (.context/session/CONTEXT-baseline-llm.md)

# Baseline Context

saved: {ISO 8601 timestamp}
stream: baseline
manifest: .context/session/ctx/manifest.yaml
source: .context/session/in/

## Project

ref: .context/session/ctx/manifest.yaml
source_folder: .context/session/in/
files: {total_count}

## Sources (inline)

### {filename}
{Full content from .context/session/ctx/{file}}

## Sources (summarized)

### {filename}
See: `.context/session/ctx/{nn}-{basename}-summary-llm.md`

## Sources (reference only)

- `.context/session/in/{path}`: {description}

## Refs

manifest: .context/session/ctx/manifest.yaml
summaries: [.context/session/ctx/01-*.md, .context/session/ctx/02-*.md, ...]
source: .context/session/in/

Token budget: ≤2000 tokens total.

Validation Rules

Required: project, created, source_folder, sources (high/medium/low)
File paths: Relative to .context/session/in/, must exist at generation time
Descriptions: Required, non-empty, concise (1-2 sentences)
Action field: Auto-set, user can override
Tags: Optional, keys alphanumeric/hyphens/underscores
All priority sections: Must be present (can be empty arrays)

Security

Auto-skipped: .env*, *credentials*, *secrets*, *token*, *.key, *.pem, *.crt

RISEN INPUT Table (output)

| Priority | File | Description |
|----------|------|-------------|
| 1 (HIGH) | @.context/session/ctx/proposal.md | Main objectives |
| 2 (MED) | @.context/session/ctx/style-guide.md | Style reference |
| 3 (LOW) | @.context/session/in/old-notes.md | Background (ref only) |
