Specification Context Loading

Discovers and loads project specifications, active changes, and requirements to provide context.

Quick Start

Context loading helps answer:

What specs exist in this project?

What changes are currently active?

What requirements are defined?

What capabilities does the system have?

Where is a specific feature specified?

Basic pattern: Search → Read → Summarize

Discovery Commands

List All Specifications
# Find all spec files
find spec/specs -name "spec.md" -type f

# Find all capability directories
find spec/specs -mindepth 1 -maxdepth 1 -type d

# Show spec tree
tree spec/specs/  # if tree is installed
# or
ls -R spec/specs/

Output format:

spec/specs/
├── authentication/
│   └── spec.md
├── billing/
│   └── spec.md
└── notifications/
    └── spec.md

List Active Changes

# Show all active changes
find spec/changes -maxdepth 1 -type d -not -path "spec/changes" -not -path "*/archive" | sort

# Show with modification dates
find spec/changes -maxdepth 1 -type d -not -path "spec/changes" -not -path "*/archive" -exec ls -ld {} \;

# Count active changes
find spec/changes -maxdepth 1 -type d -not -path "spec/changes" -not -path "*/archive" | wc -l

List Archived Changes

# Show all archived changes
ls -1 spec/archive/

# Show with dates
ls -la spec/archive/

# Find recently archived (last 7 days)
find spec/archive/ -maxdepth 1 -type d -mtime -7

Search for Requirements

# Find all requirements
grep -r "### Requirement:" spec/specs/

# Find requirements in specific capability
grep "### Requirement:" spec/specs/authentication/spec.md

# List unique requirement names
grep -h "### Requirement:" spec/specs/**/*.md | sed 's/### Requirement: //' | sort

Search for Scenarios

# Find all scenarios
grep -r "#### Scenario:" spec/specs/

# Count scenarios per spec
for spec in spec/specs/**/spec.md; do
    count=$(grep -c "#### Scenario:" "$spec")
    echo "$spec: $count scenarios"
done

Search by Keyword

# Find specs mentioning "authentication"
grep -r -i "authentication" spec/specs/

# Find requirements about "password"
grep -B 1 -A 5 -i "password" spec/specs/**/*.md | grep -A 5 "### Requirement:"

# Find scenarios about "error"
grep -B 1 -A 10 -i "error" spec/specs/**/*.md | grep -A 10 "#### Scenario:"

Common Queries

Query 1: "What specs exist?"

# List all capabilities
find spec/specs -mindepth 1 -maxdepth 1 -type d -exec basename {} \;

# Count requirements per capability
for cap in spec/specs/*/; do
    name=$(basename "$cap")
    count=$(grep -c "### Requirement:" "$cap/spec.md" 2>/dev/null || echo "0")
    echo "$name: $count requirements"
done

Response format:

## Existing Specifications

The project has specifications for the following capabilities:

- **authentication**: 8 requirements
- **billing**: 12 requirements
- **notifications**: 5 requirements

Total: 3 capabilities, 25 requirements

Query 2: "What changes are active?"

# List with proposal summaries
for change in spec/changes/*/; do
    if [ "$change" != "spec/changes/archive/" ]; then
        id=$(basename "$change")
        echo "=== $id ==="
        head -n 20 "$change/proposal.md" | grep -A 3 "## Why"
    fi
done

Response format:

## Active Changes

Currently active changes:

### add-user-auth
**Why**: Users need secure authentication...

### update-billing-api

Total: 2 active changes

Query 3: "Show me the authentication spec"

# Read full spec
cat spec/specs/authentication/spec.md

# Or show summary
echo "Requirements:"
grep "### Requirement:" spec/specs/authentication/spec.md

echo "\nScenarios:"
grep "#### Scenario:" spec/specs/authentication/spec.md

Response format:

## Authentication Specification

(Include full content of spec.md)

Summary:
- 8 requirements
- 16 scenarios
- Last modified: [date from git log]

Query 4: "Find specs about password"

# Search for keyword
grep -r -i "password" spec/specs/ -A 5

# Show which specs mention it
grep -r -i "password" spec/specs/ -l

Response format:

## Specs Mentioning "Password"

Found in:
- spec/specs/authentication/spec.md (3 requirements)
- spec/specs/security/spec.md (1 requirement)

Relevant requirements:
### Requirement: Password Validation
### Requirement: Password Reset
### Requirement: Password Strength

Query 5: "What's in change X?"

# Show full change context
CHANGE_ID="add-user-auth"

echo "=== Proposal ==="
cat spec/changes/$CHANGE_ID/proposal.md

echo "\n=== Tasks ==="
cat spec/changes/$CHANGE_ID/tasks.md

echo "\n=== Spec Deltas ==="
find spec/changes/$CHANGE_ID/specs -name "*.md" -exec echo "File: {}" \; -exec cat {} \;

Advanced Queries

Find Related Requirements

# Find requirements that mention another requirement
grep -r "User Login" spec/specs/ -A 10 | grep "### Requirement:"

# Find cross-references
grep -r "See Requirement:" spec/specs/

Analyze Coverage

# Find requirements without scenarios
for spec in spec/specs/**/spec.md; do
    awk '/### Requirement:/ {req=$0; getline; if ($0 !~ /#### Scenario:/) print req}' "$spec"
done

# Find scenarios without proper Given/When/Then
grep -A 5 "#### Scenario:" spec/specs/**/*.md | grep -v "GIVEN\|WHEN\|THEN"

Compare Active vs Archive

# Show evolution over time
echo "Archive history:"
ls -1 spec/archive/ | head -10

echo "Recent archives (last 30 days):"
find spec/archive/ -maxdepth 1 -type d -mtime -30 -exec basename {} \;

Search Patterns

Pattern 1: Capability Discovery

User asks: "What can the system do?"

# List capabilities
find spec/specs -mindepth 1 -maxdepth 1 -type d -exec basename {} \;

# Show high-level requirements
for cap in spec/specs/*/; do
    echo "=== $(basename $cap) ==="
    grep "### Requirement:" "$cap/spec.md" | head -3
done

Pattern 2: Feature Search

User asks: "Is there a spec for password reset?"

# Search for keyword
grep -r -i "password reset" spec/specs/ -B 1 -A 10

# If found, show full requirement
grep -B 1 -A 20 "Requirement:.*Password Reset" spec/specs/**/*.md

Pattern 3: Change Tracking

User asks: "What's being worked on?"

# Show active changes with status
for change in spec/changes/*/; do
    if [ "$change" != "spec/changes/archive/" ]; then
        id=$(basename "$change")
        echo "$id:"
        test -f "$change/IMPLEMENTED" && echo "  Status: Implemented" || echo "  Status: In Progress"
        echo "  Tasks: $(grep -c "^[0-9]\+\." "$change/tasks.md")"
    fi
done

Best Practices

Pattern 1: Provide Context Before Details

Good flow:

1. Show dashboard (high-level overview)
2. User asks about specific capability
3. Show that capability's requirements
4. User asks about specific requirement
5. Show full requirement with scenarios

Pattern 2: Use Grep Efficiently

# Combine filters for precision
grep -r "### Requirement:" spec/specs/ | grep -i "auth"

# Use context flags for readability
grep -B 2 -A 10 "#### Scenario:" spec/specs/authentication/spec.md

Pattern 3: Aggregate Information

Don't just dump file contents. Summarize:

**Bad**: (dump entire spec file)

**Good**:
"The authentication spec has 8 requirements covering:
- User login
- Password management
- Session handling
- Multi-factor authentication

Would you like details on any specific requirement?"

Anti-Patterns to Avoid

Don't:

Read entire spec files without user request

List every single requirement by default

Show raw grep output without formatting

Assume user knows capability names

Do:

Start with high-level overview

Ask which area user wants to explore

Format output clearly

Provide navigation hints
