Session Skills

Skills for session management and protocol compliance.

Triggers

Phrase	Action
Check if I can skip QA	Run test_investigation_eligibility.py
Am I eligible for investigation-only?	Verify staged files against ADR-034 allowlist
Verify investigation session eligibility	Check QA skip eligibility before commit
Can I use SKIPPED: investigation-only?	Validate investigation-only exemption
Test eligibility for QA skip	Execute eligibility check script

When to Use

Use this skill when:

• About to commit investigation-only work and need to verify QA skip eligibility
• Session log uses "SKIPPED: investigation-only" verdict
• Staged files should be checked against ADR-034 allowlist

Use session-init instead when:

• Starting a new session and creating the session log
• Need protocol-compliant session initialization

Use the qa agent instead when:

• Feature implementation work was done (not investigation-only)
• Eligibility check returns Eligible: false

Process

Phase 1: Eligibility Check

Step	Action	Tool	Output
1.1	Stage files for commit	git add	Files added to staging area
1.2	Run eligibility check	test_investigation_eligibility.py	JSON with Eligible, StagedFiles, Violations
1.3	Verify Eligible=true	Parse JSON output	Boolean result

Phase 2: Commit Decision

Step	Action	Condition	Next Step
2.1	Proceed with investigation-only skip	Eligible=true, Violations=[]	Use "SKIPPED: investigation-only"
2.2	Address violations or invoke qa agent	Eligible=false	Fix violations or start new session

Quick Reference

Skill	Purpose	When to Use
Test-InvestigationEligibility	Check if staged files qualify for investigation-only QA skip	Before committing with SKIPPED: investigation-only

Test Investigation Eligibility

Check if staged files qualify for investigation-only QA skip per ADR-034.

Trigger Phrases

• "Check if I can skip QA"
• "Am I eligible for investigation-only?"
• "Verify investigation session eligibility"
• "Can I use SKIPPED: investigation-only?"

Usage

python3 .claude/skills/session/scripts/test_investigation_eligibility.py

Output

Returns JSON with:

Field	Type	Description
Eligible	boolean	true if all staged files are in allowlist
StagedFiles	array	All staged file paths
Violations	array	Files not in allowlist (empty if eligible)
AllowedPaths	array	Reference list of allowed path prefixes
Error	string	Present only on git errors

Exit Codes

Code	Meaning
0	Success (eligibility result in JSON output)

Note: The script always exits 0. Check the Eligible field in the JSON output to determine eligibility. The Error field is present when git commands fail.

Error Handling

Scenario	Behavior	Output
Not in git repository	Returns JSON with Eligible: false	Error field explains the issue
Git command fails	Returns JSON with Eligible: false	Error field explains the issue
Empty staged files	Returns JSON with Eligible: true	StagedFiles is empty array
Mixed allowed/disallowed files	Returns JSON with Eligible: false	Violations lists disallowed files

Example Outputs

Eligible (investigation-only files):

{
  "Eligible": true,
  "StagedFiles": [".agents/sessions/2025-01-01-session-01.md"],
  "Violations": [],
  "AllowedPaths": [
    ".agents/sessions/",
    ".agents/analysis/",
    ".agents/retrospective/",
    ".serena/memories/",
    ".agents/security/"
  ]
}

Not eligible (contains code files):

{
  "Eligible": false,
  "StagedFiles": [
    ".agents/sessions/2025-01-01-session-01.md",
    "scripts/MyScript.ps1"
  ],
  "Violations": ["scripts/MyScript.ps1"],
  "AllowedPaths": [
    ".agents/sessions/",
    ".agents/analysis/",
    ".agents/retrospective/",
    ".serena/memories/",
    ".agents/security/"
  ]
}

Git error:

{
  "Eligible": false,
  "StagedFiles": [],
  "Violations": [],
  "AllowedPaths": [
    ".agents/sessions/",
    ".agents/analysis/",
    ".agents/retrospective/",
    ".serena/memories/",
    ".agents/security/"
  ],
  "Error": "Not in a git repository or git command failed"
}

Agent Workflow Integration

SESSION-PROTOCOL.md Relationship

This skill implements the verification step for Phase 2.5: QA Validation of the Session End Protocol:

SESSION-PROTOCOL.md (Phase 2.5: QA Validation)
                │
                ├── Feature implementation → MUST invoke qa agent
                │
                └── Investigation session → MAY skip QA
                        │
                        └── test_investigation_eligibility.py
                                │
                                ├── Eligible: true → Use "SKIPPED: investigation-only"
                                │
                                └── Eligible: false → MUST invoke qa agent

Workflow: Before Committing Investigation Work

1. Stage your files
   │
   └── git add .agents/sessions/... .serena/memories/...

2. Run eligibility check
   │
   └── python3 .claude/skills/session/scripts/test_investigation_eligibility.py

3. Check output
   │
   ├── Eligible: true
   │   └── Safe to commit with "SKIPPED: investigation-only"
   │
   └── Eligible: false
       │
       ├── Check Violations array
       │   └── Either: Remove violating files from staging
       │   └── Or: Start new session for implementation work
       │
       └── Invoke qa agent for the implementation work

Integration with Session End Checklist

Use this skill to validate the QA skip condition:

### Session End (COMPLETE ALL before closing)

| Req | Step | Status | Evidence |
|-----|------|--------|----------|
| MUST | Route to qa agent (feature implementation) | [x] | `SKIPPED: investigation-only` - Verified via test_investigation_eligibility.py |

---

Allowed Paths (Investigation Allowlist)

These paths qualify for investigation-only QA exemption:

Path	Purpose
.agents/sessions/	Session logs documenting work
.agents/analysis/	Investigation outputs and findings
.agents/retrospective/	Learnings and retrospective documents
.serena/memories/	Cross-session context storage
.agents/security/	Security assessments and reviews

Important: This allowlist is defined by ADR-034 (Investigation Session QA Exemption). The patterns in test_investigation_eligibility.py are validated by Pester tests to ensure they match the ADR specification.

---

Anti-Patterns

Avoid	Why	Instead
Skipping eligibility check	May commit ineligible files with investigation-only skip	Always run the skill before using the skip
Ignoring violations	QA exemption won't be valid	Address violations or invoke qa agent
Using for code changes	Investigation-only is for analysis, not implementation	Start a new session for code work
Hardcoding path checks	Patterns may drift from ADR-034 specification	Use this skill which implements the ADR patterns

---

Verification Checklist

After using this skill:

• Skill output shows Eligible: true
• No Violations in output
• No Error field in output
• Session log evidence updated with skill output
