Knowledge Intake#

Process external resources into the knowledge store. When a user links an article, blog post, or paper, this skill guides evaluation, storage decisions, and application routing.

When To Use#

• Capturing and organizing knowledge from sessions
• Ingesting information into structured memory palaces

When NOT To Use#

• Temporary notes that do not need long-term storage
• Code-only changes without knowledge capture needs

What It Is#

A knowledge governance framework that answers three questions for every external resource:

1. Is it worth storing? - Evaluate signal-to-noise and relevance
2. Where does it apply? - Route to local codebase or meta-infrastructure
3. What does it displace? - Identify outdated knowledge to prune

The Intake Signal#

When a user links an external resource, it is a signal of importance.

The act of sharing indicates the resource passed the user's own filter. Our job is to:

• Extract the essential patterns and insights
• Determine appropriate storage location and format
• Connect to existing knowledge structures
• Identify application opportunities

Quick Start#

When a user shares a link:

text

1. FETCH    → Detect format, retrieve and convert content
2. EVALUATE → Apply importance criteria
3. DECIDE   → Storage location and application type
4. STORE    → Create structured knowledge entry
5. VALIDATE → Scribe verification (slop scan + doc verify)
6. CONNECT  → Link to existing palace structures
7. PROMOTE  → Offer Discussion promotion (score 80+)
8. APPLY    → Route to codebase or infrastructure updates
9. PRUNE    → Identify displaced/outdated knowledge

Step 1: FETCH with Format Detection#

Before retrieving content, detect the source format from the URL or file path to choose the right retrieval method.

Web articles and blog posts (default path): Use WebFetch to retrieve HTML content directly. No conversion needed.

Document URLs (PDF, DOCX, PPTX, XLSX): Apply the leyline:document-conversion protocol. This tries the markitdown MCP tool first for high-quality markdown, then falls back to native Claude Code tools (Read for PDFs, etc.), then informs the user if the format is unsupported without markitdown.

Local files (user shares a file path): Construct a file:// URI from the absolute path and apply the leyline:document-conversion protocol.

Format detection heuristics:

URL PatternFormatRetrieval*.pdf, arxiv.org/pdf/*PDFdocument-conversion*.docx, *.docWorddocument-conversion*.pptx, *.pptPowerPointdocument-conversion*.xlsx, *.xlsExceldocument-conversion*.epubE-bookdocument-conversiondrive.google.com/*Variousdocument-conversionEverything elseHTML/webWebFetch (existing)

After retrieval (regardless of method), wrap the content in external content boundary markers per leyline:content-sanitization before proceeding to Step 2 (EVALUATE).

Step 5: Scribe Validation (Required)#

All knowledge corpus entries MUST pass scribe validation before finalizing.

Run Skill(scribe:slop-detector) on the new entry:

• Score must be < 2.5 (Clean to Light)
• No Tier 1 markers (delve, tapestry, comprehensive, leveraging, etc.)
• Hedge word density < 15 per 1000 words

Use Agent(scribe:doc-verifier) to validate:

• All file paths and URLs exist
• All cross-references valid
• Source attributions accurate

bash

# Quick validation for knowledge corpus entry
/slop-scan docs/knowledge-corpus/[entry-name].md
# Doc verification is now agent-only:
Agent(scribe:doc-verifier) "Verify docs/knowledge-corpus/[entry-name].md"

DO NOT finalize entries with slop score > 2.5 - rewrite with concrete specifics. Verification: Run the command with --help flag to verify availability.

Step 7: Discussion Promotion (Score 80+ Only)#

When the evaluation score is 80-100 (evergreen), you MUST execute the Discussion promotion workflow. If the score is below 80, skip this step entirely.

Execute these steps in order:

1. Read modules/discussion-promotion.md for the full GraphQL workflow
2. Tell the user: "This entry has reached evergreen maturity. Publishing to GitHub Discussions. [Y/n]"
3. If the user says "n", skip to Step 8 (APPLY)
4. Run the gh api graphql commands from the module to create or update a Discussion in the "Knowledge" category
5. Update the local corpus entry with discussion_url

• If the entry already has a discussion_url field, update the existing Discussion instead of creating a new one
• If gh is unavailable or promotion fails, warn the user and continue to Step 8 (APPLY)

Publishing is the default for qualifying entries. It never blocks the intake workflow.

Evaluation Framework#

Importance Criteria#

CriterionWeightQuestionsNovelty25%Does this introduce new patterns or concepts?Applicability30%Can we apply this to current work?Durability20%Will this remain relevant in 6+ months?Connectivity15%Does it connect to multiple existing concepts?Authority10%Is the source credible and well-reasoned?

Scoring Guide#

• 80-100: Evergreen knowledge, store prominently, apply immediately
• 60-79: Valuable insight, store in corpus, schedule application
• 40-59: Useful reference, store as seedling, revisit later
• Below 40: Low priority, capture key quote only or skip

Application Routing#

Local Codebase Application#

Apply when knowledge directly improves current project:

• Bug fix patterns
• Performance optimizations
• Architecture decisions for this codebase
• Tool/library recommendations

Action: Update code, add comments, create ADR

Meta-Infrastructure Application#

Apply when knowledge improves our plugin ecosystem:

• Skill design patterns
• Agent behavior improvements
• Workflow optimizations
• Learning/evaluation methods (like Franklin Protocol)

Action: Update skills, create modules, enhance agents

The Tidying Imperative (KonMari-Inspired)#

"A cluttered palace is a cluttered mind."

New knowledge often displaces old—but time is not the criterion. Relevance and aspirational alignment are.

The Master Curator#

The human in the loop defines what stays. Before major tidying:

1. Who are you becoming? - Your aspirations as a developer
2. What excites you now? - Genuine enthusiasm, not "should"
3. What have you outgrown? - Past interests consciously left behind

The Two Questions#

For each piece of knowledge, both must be yes:

• Does it spark joy? - Genuine enthusiasm, not obligation
• Does it serve your aspirations? - Aligned with who you're becoming

Tidying Actions#

FindingActionSupersedesArchive old with gratitude, link as contextContradictsEvaluate both, keep what sparks joyNo longer alignedRelease with gratitudeComplementsCreate bidirectional links

"I might need this someday" is fear, not joy. Release it.

Marginal Value Filtering (Anti-Pollution)#

"If it can't teach something the existing corpus can't already teach → skip it."

Before storing ANY knowledge, run the marginal value filter to prevent corpus pollution.

The Three-Step Filter#

1. Redundancy Check

• Exact match → REJECT immediately
• 80%+ overlap → REJECT as redundant
• 40-80% overlap → Evaluate delta (Step 2)
• <40% overlap → Likely novel, proceed to store

2. Delta Analysis (for partial overlap only)

• Novel insight/pattern → High value (0.7-0.9)
• Different framing only → Low value (0.2-0.4)
• More examples → Marginal value (0.4-0.6)
• Contradicts existing → Investigate (0.6-0.8)

3. Integration Decision

• Standalone: Novel content, no significant overlap
• Merge: Enhances existing entry with examples/details
• Replace: Supersedes outdated knowledge
• Skip: Insufficient marginal value

Using the Filter#

python

from memory_palace.corpus import MarginalValueFilter

# Initialize filter with corpus and index directories
filter = MarginalValueFilter(
    corpus_dir="docs/knowledge-corpus",
    index_dir="docs/knowledge-corpus/indexes"
)

# Evaluate new content
redundancy, delta, integration = filter.evaluate_content(
    content=article_text,
    title="Structured Concurrency in Python",
    tags=["async", "concurrency", "python"]
)

# Get human-readable explanation
explanation = filter.explain_decision(redundancy, delta, integration)
print(explanation)

# Act on decision
if integration.decision == IntegrationDecision.SKIP:
    print(f"Skipping: {integration.rationale}")
elif integration.decision == IntegrationDecision.STANDALONE:
    # Store as new entry
    store_knowledge(content, title)
elif integration.decision == IntegrationDecision.MERGE:
    # Enhance existing entry
    enhance_entry(integration.target_entries[0], content)
elif integration.decision == IntegrationDecision.REPLACE:
    # Replace outdated entry
    replace_entry(integration.target_entries[0], content)

Verification: Run the command with --help flag to verify availability.

Filter Output Example#

text

**Verification:** Run the command with `--help` flag to verify availability.
=== Marginal Value Assessment ===

Redundancy: partial
Overlap: 65%
Matches: async-patterns, python-concurrency
  - Partial overlap (65%) with 2 entries

Delta Type: novel_insight
Value Score: 75%
Teaching Delta: Introduces 8 new concepts
Novel aspects:
  + New concepts: structured, taskgroup, context-manager
  + New topics: Error Propagation, Resource Cleanup

Decision: STANDALONE
Confidence: 80%
Rationale: Novel insights justify standalone: Introduces 8 new concepts

Verification: Run the command with --help flag to verify availability.

Progressive Autonomy Integration#

The marginal value filter respects autonomy levels (see plan Phase 4):

• Level 0: ALL decisions require human approval
• Level 1: Auto-approve 85+ scores in known domains
• Level 2: Auto-approve 70+ scores in known domains
• Level 3: Auto-approve 60+, auto-reject obvious noise

Current implementation: Level 0 (all human-in-the-loop).

RL-Based Quality Scoring#

The knowledge corpus uses reinforcement learning signals to dynamically score entry quality based on actual usage patterns.

Usage Signals#

SignalWeightDescriptionACCESS+0.1Entry was accessed/readCITATION+0.3Entry was cited in another contextPOSITIVE_FEEDBACK+0.5User marked as helpfulNEGATIVE_FEEDBACK-0.3User marked as unhelpfulCORRECTION+0.2Entry was corrected/updatedSTALE_FLAG-0.4Entry marked as potentially outdated

Quality Decay Model#

Knowledge entries decay over time unless validated:

MaturityHalf-LifeDecay CurveSeedling14 daysExponentialGrowing30 daysExponentialEvergreen90 daysLogarithmic

Entries are classified by decay status:

• Fresh: >70% quality retained
• Stale: 40-70% quality retained
• Critical: 20-40% quality retained
• Archived: <20% quality retained

Source Lineage Tracking#

Hybrid lineage tracking based on source importance:

Full Lineage (for important sources):

• Primary source with complete metadata
• Derivation chain (what entries it was derived from)
• Transformation history (summarization, extraction, etc.)
• Validation chain (who validated and when)

Simple Lineage (for standard sources):

• Source type and URL
• Retrieval timestamp

Full lineage is used for:

• Research papers
• Documentation
• Entries with importance score >= 0.7

Knowledge Orchestrator#

The KnowledgeOrchestrator coordinates all quality systems:

python

from memory_palace.corpus import KnowledgeOrchestrator, UsageSignal

# Initialize orchestrator
orchestrator = KnowledgeOrchestrator(
    corpus_dir="docs/knowledge-corpus",
    index_dir="docs/knowledge-corpus/indexes"
)

# Record usage events
orchestrator.record_usage("entry-1", UsageSignal.ACCESS)
orchestrator.record_usage("entry-1", UsageSignal.POSITIVE_FEEDBACK)

# Assess entry quality
entry = {"id": "entry-1", "maturity": "growing"}
assessment = orchestrator.assess_entry(entry)
print(f"Quality: {assessment.overall_score:.0%}")
print(f"Status: {assessment.status}")
print(f"Recommendations: {assessment.recommendations}")

# Get maintenance queue
entries = [...]  # Your entry list
queue = orchestrator.get_maintenance_queue(entries)
for item in queue:
    print(f"{item.entry_id}: {item.status} - {item.recommendations}")

# Ingest new content with lineage
from memory_palace.corpus import SourceReference, SourceType

source = SourceReference(
    source_id="src-1",
    source_type=SourceType.DOCUMENTATION,
    url="https://docs.example.com/api",
    title="API Documentation"
)
entry_id, decision = orchestrator.ingest_with_lineage(
    content="# API Reference\n...",
    title="API Documentation",
    source=source
)

Verification: Run the command with --help flag to verify availability.

RL Integration with Marginal Value Filter#

The marginal value filter emits RL signals on integration decisions:

python

from memory_palace.corpus import MarginalValueFilter

filter = MarginalValueFilter(corpus_dir, index_dir)

# Evaluate with RL signal emission
redundancy, delta, integration, rl_signal = filter.evaluate_with_rl(
    content=article_text,
    title="New Article",
    tags=["python", "async"]
)

# RL signal contains:
# - signal_type: UsageSignal to emit
# - weight: Signal weight for scoring
# - action: What happened (new_entry_created, entry_enhanced, etc.)
# - decision: Integration decision made
# - confidence: Decision confidence
print(f"RL Signal: {rl_signal['action']} (weight: {rl_signal['weight']})")

Verification: Run the command with --help flag to verify availability.

Workflow Example#

User shares: "Check out this article on structured concurrency"

yaml

intake:
  source: "https://example.com/structured-concurrency"

# PHASE 3: Marginal Value Filter
marginal_value:
  redundancy:
    level: partial_overlap

  delta:
    type: novel_insight
    value_score: 0.75
    novel_aspects: [structured, taskgroup, context-manager]
    teaching_delta: "Introduces structured concurrency pattern"
  integration:
    decision: standalone
    confidence: 0.80
    rationale: "Novel insights justify standalone entry"

# Continue with evaluation if filter passes
evaluation:

  total: 82          # Evergreen, store and apply

routing:
  type: both
  local_application:
    - Refactor async error handling in current project
    - Add structured concurrency pattern to codebase
  meta_application:
    - Create module in relevant skill
    - Add to knowledge-corpus as reference

storage:
  location: docs/knowledge-corpus/structured-concurrency.md
  format: memory_palace_entry
  maturity: growing

pruning:
  displaces:
    - Old async error patterns (mark deprecated)
  complements:
    - Existing error handling module
    - Async patterns documentation

Verification: Run the command with --help flag to verify availability.

Queue Processing#

Research sessions and external content are automatically queued for review in docs/knowledge-corpus/queue/.

Processing Queue Entries#

bash

# List pending queue entries
ls -1t docs/knowledge-corpus/queue/*.yaml

# Review specific entry
cat docs/knowledge-corpus/queue/2025-12-31_topic.yaml

# Process approved entry
# 1. Create memory palace entry in docs/knowledge-corpus/
# 2. Update queue entry status to 'processed'
# 3. Archive or delete queue entry

Verification: Run the command with --help flag to verify availability.

Queue Integration#

The research-queue-integration hook automatically queues:

• Brainstorming sessions with 3+ WebSearch calls
• Research-focused sessions with substantial findings
• Manual additions via queue entry creation

Queue entry format: See docs/knowledge-corpus/queue/README.md

Queue Status Workflow#

text

**Verification:** Run the command with `--help` flag to verify availability.
pending_review → [Review] → approved/rejected
approved → [Create Entry] → processed
processed → [Archive] → queue/archive/

Verification: Run the command with --help flag to verify availability.

Automation#

• Run uv run python scripts/intake_cli.py --candidate path/to/intake_candidate.json --auto-accept
• The CLI runs marginal value filter, creates palace entries ( docs/knowledge-corpus/*.md), developer drafts ( docs/developer-drafts/), and appends audit rows to docs/curation-log.md.
• Use --output-root in tests or sandboxes to avoid mutating the main corpus.
• Queue Processing: Use --process-queue flag to review and process queued entries interactively.

Detailed Resources#

• Evaluation Rubric: See modules/evaluation-rubric.md
• Storage Patterns: See modules/storage-patterns.md
• KonMari Tidying Philosophy: See modules/konmari-tidying.md
• Tidying Workflows: See modules/pruning-workflows.md
• Discussion Promotion: Invoked in Step 7 (PROMOTE) for evergreen entries (score 80+). Publishing is the default action. See modules/discussion-promotion.md for full workflow.

Hook Integration#

Memory-palace hooks automatically detect content that may need knowledge intake processing:

Automatic Triggers#

HookEventWhen Triggeredurl_detectorUserPromptSubmitUser message contains URLsweb_content_processorPostToolUse (WebFetch/WebSearch)After fetching web contentlocal_doc_processorPostToolUse (Read)Reading files in knowledge pathsresearch_queue_integrationSessionEndResearch sessions with 3+ WebSearch calls

Hook Signals#

When hooks detect potential knowledge content, they add context messages:

text

**Verification:** Run `pytest -v` to verify tests pass.
Memory Palace: New web content fetched from {url}.
Consider running knowledge-intake to evaluate and store if valuable.

Verification: Run the command with --help flag to verify availability.

**Verification:** Run the command with `--help` flag to verify availability.
Memory Palace: Reading local knowledge doc '{path}'.
This path is configured for knowledge tracking.
Consider running knowledge-intake if this contains valuable reference material.

Verification: Run the command with --help flag to verify availability.

Deduplication#

Hooks check the memory-palace-index.yaml to avoid redundant processing:

• Known URLs: "Content already indexed" - skip re-evaluation
• Changed content: "Content has changed" - suggest update
• New content: Full evaluation recommended

Safety Checks#

Before signaling intake, hooks validate content:

• Size limits (default 500KB)
• Secret detection (API keys, credentials)
• Data bomb prevention (repetition, unicode bombs)
• Prompt injection sanitization

Index Schema Alignment#

The deduplication index stores fields aligned with this skill's evaluation:

yaml

entries:
  "https://example.com/article":
    content_hash: "xxh:abc123..."
    stored_at: "docs/knowledge-corpus/article.md"
    importance_score: 82           # From evaluation framework, in [0, 100]
    maturity: "growing"            # seedling, growing, evergreen
    routing_type: "both"           # local, meta, both
    last_updated: "2025-12-06T..."

Verification: Run the command with --help flag to verify availability.
