analytics

name: analytics description: Vault-level content analytics — file creation trends, skill adoption, contact engagement, content distribution, and unprocessed backlog detection. Outputs to _analytics/ folder. user-invocable: true argument-hint: [overview|skills|contacts|backlog|help]

/analytics -- Vault Content Analytics

Analyse the vault as a dataset — file metadata (names, dates, paths, counts), not file contents. Answers "how is my system performing?" rather than "what did I learn from this conversation?"

Standalone skill — no dependency on ops-base or ops-config.

Key distinction from /insights: The insights skill extracts knowledge from conversations (decisions, learnings, patterns about people and projects). This skill analyses the vault itself — creation velocity, skill adoption, engagement frequency, content distribution.

Design Principles

• Metadata only. Read filenames, paths, dates, and file sizes. Never read file contents except for lightweight classification (H1 heading, first line).
• Non-destructive. Only writes to _analytics/ — never modifies existing files.
• Snapshot-based. Each run produces a dated snapshot. Historical snapshots enable trend comparison.
• Privacy-aware. Contact names appear in analytics (they are folder names, not extracted content). Mark private contacts with private: true in _meta.yaml to exclude them from output.

Output Location

All output goes to {vault_root}/_analytics/:

_analytics/
├── YYMMDD-vault-overview.md       <- /analytics overview
├── YYMMDD-skill-adoption.md       <- /analytics skills
├── YYMMDD-contact-engagement.md   <- /analytics contacts
├── YYMMDD-backlog-report.md       <- /analytics backlog
└── .archive/                      <- older snapshots (auto-archived)

Archive policy: When writing a new snapshot, move any existing file of the same type to .archive/ with its date prefix preserved. Keep the latest of each type at the top level.

Vault Detection

Determine vault root:

1. Walk up from cwd looking for _contacts/ or _projects/ markers
2. Fallback: $OBSIDIAN_VAULT environment variable
3. Fallback: cwd itself

File Discovery

The core scanning step shared by all subcommands.

YYMMDD File Detection

Scan vault recursively (max depth 8, skip .archive/, .git/, node_modules/, clones/). Match files where the basename starts with 6 digits followed by a separator:

Pattern: /^(\d{6})[-_ ]/

Validate the 6 digits as a plausible date:

• Year (positions 1-2): 22-29 (2022-2029)
• Month (positions 3-4): 01-12
• Day (positions 5-6): 01-31

Metadata Collected Per File

Skill Classification

Classify each file by path first, keywords second:

Step 1 — Path-based classification (highest confidence):

Step 2 — Keyword-based classification (filename, case-insensitive):

Step 3 — Directory-context classification (for files that didn't match keywords):

Step 4 — Fallback: uncategorized

Privacy Filtering (CR-009)

Before including a contact in named output:

1. Resolve classification for the contact folder:

   • If _meta.yaml exists and has classification field: use it
   • Else if _meta.yaml exists and has private: true: treat as personal
   • Else check folder name against privacy_defaults in base.yaml:
     • _contacts/a1-* or _contacts/a2* → family
   • Else default: professional

2. Apply filtering by subcommand:

   • /analytics contacts: Exclude family and personal contacts from output
   • /analytics overview, /analytics skills: Include all files in aggregate counts without contact attribution
   • /analytics backlog: Include all files (backlog is about content gaps, not people)

3. Never expose family/personal contact names in any output file. Aggregate their files into totals only.

Subcommands

overview -- Vault-wide metrics snapshot

Trigger: /analytics overview or /analytics (default subcommand)

Steps:

1. Run file discovery (scan vault)
2. Compute summary metrics:
   • Total YYMMDD files, date range, unique active dates, active months
   • Current pace (files/day for current quarter)
   • Trend direction (current quarter rate vs previous quarter rate)
3. Compute yearly totals with year-over-year growth multiplier
4. Compute content type × quarter pivot — the core analytical view showing how each skill type's volume evolves over time. Columns: transcript, ops/meeting, preparation, ops, travel, raw-text, uncategorized, other. Use · for zero cells.
5. Compute content type × month pivot (last 12 months) — same columns, monthly granularity for recent trends
6. Compute monthly activity bar chart (last 12 months)
7. Compute quarterly trend table with deltas
8. Compute distributions:
   • By skill type — table with count and percentage
   • By top-level directory — top 15 areas with count (private contacts aggregated as single anonymous row)
   • By file extension — count per extension
   • By day of week — weekday vs weekend pattern with bar chart
9. Compute top 5 busiest dates — date, day of week, count
10. Write to _analytics/YYMMDD-vault-overview.md

skills -- Skill adoption analysis

Trigger: /analytics skills

Steps:

1. Run file discovery
2. Build skill share pivot (absolute) — same columns as the overview pivot (transcript, ops/meeting, preparation, ops, travel, raw-text, uncategorized, other), one row per quarter. Use · for zero cells.
3. Build skill share pivot (percentage) — same layout but percentages per quarter.
4. For each skill type, compute per-skill summary:
   • First appeared — which quarter the skill type first produced files
   • Total files across all time
   • Current share — percentage in the most recent full quarter, with ↑/↓/→ arrow vs previous quarter
   • Peak quarter — quarter with most files from this skill
5. Compute structured vs unstructured ratio by quarter. Structured = transcript + ops/meeting + preparation + ops. Unstructured = everything else. Show absolute counts, and a trend line from first to last full quarter.
6. Write to _analytics/YYMMDD-skill-adoption.md

Output format:

contacts -- Contact engagement analysis

Trigger: /analytics contacts

Steps:

1. Run file discovery, filtered to _contacts/ paths
2. Apply privacy filter — resolve classification per contact (see Privacy Filtering section). Exclude family and personal contacts from named output. Report count and total files of excluded contacts as an anonymous summary line.
3. For each remaining (professional) contact, compute:
   • Total file count
   • First and last file dates (as YYYY-MM)
   • Active months count
   • Peak month (month with most files, with count)
   • Average files per active month
   • Quarterly activity map (for timeline visualisation)
4. Compute contact lifecycle metrics:
   • New contacts by year — when contacts first appeared, with cumulative total
   • Active contacts per quarter — contacts with at least 1 file in the quarter
5. Sort contacts by total file count descending
6. Generate activity timelines — a monospace block showing quarterly engagement density for top 20 contacts using heat notation: · = 0, ░ = 1-2, ▒ = 3-5, ▓ = 6-10, █ = 11+
7. Write to _analytics/YYMMDD-contact-engagement.md

Output format:

# Vault Analytics — Contact Engagement
Generated: YYYY-MM-DD

*N private contacts excluded (N files in aggregate totals only)*

backlog -- Unprocessed content detection

Trigger: /analytics backlog

Identifies content that may benefit from processing through existing skills.

Steps:

1. Run file discovery
2. Detect unprocessed transcriptions:
   • Find .txt files with YYMMDD prefix (classified as raw-text)
   • These are likely raw transcriptions that haven't been processed through /transcript
   • Group by directory, sorted by count descending, show count and date range
3. Detect orphaned content:
   • Find directories containing YYMMDD-prefixed files but no CHANGELOG.md
   • Only include directories with 2+ files (single files are likely intentional one-offs)
   • Show top 15 by file count, with *(+ N more)* if truncated
4. Detect stale inbox items:
   • Read _inbox/_inbox.yaml if it exists
   • Count items with status: pending
   • Report age of oldest pending item
5. Detect insight gaps:
   • Find folders with CHANGELOG.md but no _insights.yaml
   • Count YYMMDD-prefixed files in each (potential insight yield)
   • Only include folders with 1+ transcript files
   • Show top 15 by transcript count, with *(+ N more)* if truncated
6. Write summary table at top with all four categories and suggested actions
7. Write to _analytics/YYMMDD-backlog-report.md

Output format:

# Vault Analytics — Backlog Report
Generated: YYYY-MM-DD

## Summary

| Category | Items | Potential action |
|----------|------:|-----------------|
| Raw text files (.txt) | N | `/transcript` or `/inbox` |
| Folders without CHANGELOG | N dirs, N files | Manual triage |

help -- Usage guide

Trigger: /analytics help

Output:

/analytics -- Vault Content Analytics
======================================

Analyse the vault as a dataset -- file metadata, not contents.

Usage:
  /analytics                      Vault overview (default)
  /analytics overview             Same as above
  /analytics skills               Skill adoption over time
  /analytics contacts             Contact engagement timelines
  /analytics backlog              Unprocessed content detection
  /analytics help                 This guide

Output: _analytics/ folder in vault root (one snapshot per run).

Data flow:
  YYMMDD-*.* files  ──>  /analytics  ──>  _analytics/YYMMDD-*.md
  (read filenames,        (classify,       (markdown snapshots,
   paths, dates)           aggregate)       one per subcommand)

Related skills:
  /insights          Extract knowledge FROM file contents
  /insights status   Count _insights.yaml coverage
  /daily-dashboard   Daily view (today's meetings + tasks)
  /analytics         Longitudinal view (trends over time)

Language

Output language follows the same resolution as other standalone skills:

1. If vault root CLAUDE.md specifies a language policy, follow it
2. Default: Swedish for section headers and labels, English for technical terms
3. Swedish text MUST use correct å, ä, ö characters

Notes

• The _analytics/ folder is created automatically on first run
• Old snapshots are archived to _analytics/.archive/ — never deleted
• This skill does NOT read _insights.yaml files — that's the visualisation app's domain
• This skill does NOT read file contents (except optional H1 heading for display)
• Contact privacy is respected via _meta.yaml private: true
• The skill classification algorithm uses path first, keywords second — this avoids the ~17% miscount that pure keyword matching produces (e.g., acme/meetings/ files with descriptive names)
• Quarterly comparisons handle partial quarters gracefully — the current quarter is annualised for trend comparison
