| name | knowledge-bootstrap |
| description | Initialize all knowledge subsystems at session start to load active dataset context, user profile, corrections, learnings, query archaeology, and analysis history into working memory. Use this skill automatically at the start of EVERY new session, immediately after the conversation begins. Also trigger after `/connect-data` or `/switch-dataset` to reload dataset context. Apply when the system detects missing or stale knowledge files, when returning to the tool after a break, during session initialization, at the beginning of any conversation, when Claude Code first starts, when a new Claude conversation opens, or at any session boundary. This skill is critical for contextual awareness — it ensures you understand the user's data environment, preferences, and past work before beginning any analysis. Without running this skill at session start, you lack essential context about what dataset is active, what the user prefers, and what corrections have been logged. Always run this skill first, before responding to any analytical request. Even if the user's first message is a simple question like "what's our conversion rate?", you MUST bootstrap knowledge context before answering so you know which dataset to query and what format the user expects. Make this skill your default session initialization behavior — treat it like loading configuration at startup. If you're ever unsure whether a session just started, err on the side of running bootstrap. The skill gracefully handles missing files, so running it unnecessarily is harmless, but skipping it when needed breaks contextual continuity. |
Skill: Knowledge Bootstrap
Purpose
Initialize all 7 knowledge subsystems for a new session. Loads setup state,
dataset, user profile, integrations, org context, corrections, learnings,
query archaeology, and analysis archive into working memory.
When to Use
- At the start of any session
- After
/connect-data or /switch-dataset
- When the system detects missing or stale knowledge files
Instructions
Load each subsystem in order. Every file read MUST gracefully degrade: if the
file does not exist, skip silently and note "not yet populated" in the summary.
Never block the session on a missing subsystem.
Step 1: Setup State
Read .knowledge/setup-state.yaml.
- Parse
setup_complete and count phases with status: "complete".
- If
setup_complete: false, note incomplete phases to offer /setup.
- If missing: Note "Setup: not initialized -- offer /setup".
Step 2: Active Dataset
Read .knowledge/active.yaml.
- If
active_dataset is null or missing, note "No active dataset" and continue.
- Resolve the context source first. Call
resolve_context_dir(active, project_root) from
helpers/context_sync.py -> (ctx_dir, source). If .knowledge/context-source.yaml says source: git,
it clones/pulls the team's communal context repo to a cache and returns that dataset dir; otherwise it
returns the in-repo .knowledge/datasets/{active}/. Load the dataset knowledge (semantic/, metrics/,
schema.md, quirks.md) from ctx_dir either way - the same loader, the source just differs. Report the
source ("context: local" or "context: team repo @ {ref}") in the readiness summary.
- Load from
ctx_dir:
| File | Required | If Missing |
|---|
manifest.yaml | Yes | Note "manifest missing -- not usable" |
schema.md | Yes | Generate via schema_to_markdown() or profiling |
quirks.md | No | Create empty template |
metrics/index.yaml | No | Count as 0 |
custom_instructions.md (root) else semantic/custom_instructions.md | No | Skip |
verified_queries.yaml (root) else semantic/verified_queries.yaml | No | Skip |
corrections.md (root) | No | Skip |
semantic/entities.yaml | No | Note "no semantic layer" |
semantic/relationships.yaml | No | Skip |
semantic/dimensions.yaml | No | Skip |
semantic/measures.yaml | No | Skip |
semantic/filters.yaml | No | Skip |
Store layout — root or semantic/ (backward-compatible). Three of these files can live at EITHER
the dataset root ({ctx_dir}/) OR under semantic/ ({ctx_dir}/semantic/), depending on the store's
layout: custom_instructions.md, verified_queries.yaml, and corrections.md. Reconciled stores keep
them at the dataset root; older stores keep the first two under semantic/. For each of the three,
check the dataset root first; if present, load it from there, ELSE fall back to semantic/. Do not
require one layout over the other, and do not skip the file just because it is absent from semantic/ —
it may be at the root, and vice versa. The five pure-semantic YAMLs (entities, relationships,
dimensions, measures, filters) always live under semantic/ and are not root-or-semantic.
corrections.md is the store-level communal corrections home — a human-curated, cross-session list
of standing corrections that ship WITH the dataset context (root-or-nothing; there is no semantic/
fallback for it). It is DISTINCT from the per-session correction log at .knowledge/corrections/index.yaml
loaded in Step 6 — that one is the local session log, this one is the communal store file. Load both;
they are different subsystems.
Semantic layer (load before writing any SQL). The semantic/ files are the agent's map of the data,
and the metric definitions are defined by MEANING, not by a stored number. Always load entities.yaml
(authoritative source table + keys + grain + caveats per concept), relationships.yaml (verified joins +
cardinality), and custom_instructions.md (cross-cutting business rules and gotchas — resolved root-first
then semantic/ per the layout rule above), they are small and always relevant. Consult dimensions.yaml
(synonyms + real sample values), measures.yaml, filters.yaml (named filters), and verified_queries.yaml
(blessed question -> SQL exemplars, likewise root-first then semantic/) when writing a query.
Before writing SQL: resolve the question's metric against metrics/index.yaml, pick the authoritative
table(s) and join(s) from entities/relationships, use real sample_values for filter literals (never
invent them), reuse a named filter or a verified query when one matches, and apply the custom instructions
and any standing corrections from corrections.md.
Schema generation if schema.md is missing (REQUIRED):
The schema is critical for SQL queries and analysis — never proceed without it.
Follow this sequence:
- Check
data/schemas/{active}.yaml — if found, import schema_to_markdown() from helpers/schema_helpers.py and generate schema.md
- If no YAML schema file exists, use
get_connection_for_profiling() to query the live database and generate schema.md from introspection
- For CSV datasets, read the first 1000 rows of each file with pandas, infer dtypes, and write schema.md with table/column/type info
- Staleness check: if
last_profile.md exists and is newer than schema.md, regenerate
After generation, write schema.md to .knowledge/datasets/{active}/schema.md so future sessions can load it directly.
System variables from manifest:
Extract these variables for use in SQL queries and agent prompts:
{{SCHEMA}} — Schema prefix for external warehouses (e.g., "analytics", "prod")
{{DISPLAY_NAME}} — User-friendly dataset name for status messages
{{DATE_RANGE}} — Available date range (e.g., "2024-01-01 to 2026-03-31")
{{DATABASE}} — Database name or connection string
Use {{SCHEMA}} as a prefix in SQL queries when querying external warehouses (BigQuery, Snowflake, Postgres). For local DuckDB/CSV, it's typically null.
Step 3: User Profile
Read .knowledge/user/profile.md.
- If exists: Apply
Detail level, Chart preference, Narrative style.
- If missing: Create from template (see below), note "Profile: new".
On explicit user corrections during session, update the profile:
append YYYY-MM-DD | Assumed [X] | User prefers [Y] to the Corrections Log
section. Never infer from silence.
Step 4: User Integrations
Read .knowledge/user/integrations.yaml.
- Extract
preferred_export_format, communication.detail_level.
- Count configured channels (
configured: true).
- If missing: Note "Integrations: not configured -- defaults apply".
Step 5: Organization Context
Check for org ID in setup-state.yaml (phases.phase_3_business.data.organization_id)
or in the active dataset manifest's organization field.
If an org ID exists and is not _example:
- Read
.knowledge/organizations/{org_id}/manifest.yaml for name, industry.
- Read
.knowledge/organizations/{org_id}/business/index.yaml for section counts
(glossary terms, products, metrics, objectives, teams).
- If org dir missing: Note "Org: linked but not found".
If no org linked: Note "Org: not configured".
Step 6: Corrections
Read .knowledge/corrections/index.yaml.
- Extract
total_corrections and by_severity counts.
- If
total_corrections > 0, highlight critical/high counts so agents check
the full log before writing SQL.
- If missing: Note "Corrections: not yet populated".
Step 7: Learnings
Read .knowledge/learnings/index.md.
- Scan for category headings (
### N. Category Name).
- Note which categories have content entries vs are empty.
- Do NOT load full content -- just category presence.
- If missing: Note "Learnings: not yet populated".
Step 8: Query Archaeology
Read .knowledge/query-archaeology/curated/index.yaml.
- Extract
cookbook_entries, table_cheatsheets, join_patterns counts.
- If missing: Note "Archaeology: not yet populated".
Step 9: Analysis Archive
Read .knowledge/analyses/index.yaml:
- Extract
total_analyses and last 5 entries (title, date, findings count, level).
- If most recent analysis was <24h ago: Add to user-facing status as "Recent work: [title] from [date]" and suggest "Want to build on your recent analysis?" This helps users pick up where they left off.
Read .knowledge/analyses/_patterns.yaml:
- Count
patterns[] entries and note pattern names if any.
- If missing: Note "Patterns: not yet populated".
Step 10: Mark Bootstrap Complete
Write a completion signal so agents can check if bootstrap already ran this session:
import yaml
from datetime import datetime
timestamp = datetime.now().isoformat()
with open('.knowledge/.bootstrap_timestamp', 'w') as f:
yaml.dump({'last_bootstrap': timestamp, 'status': 'complete'}, f)
This prevents redundant re-runs mid-session. To check if bootstrap is needed, read this file and compare timestamps — if <5 minutes old, skip re-running.
Step 11: Report Readiness
Compile an internal context summary (held in working memory, not shown raw):
Setup: {complete (N/M phases) | incomplete (list missing) | not initialized}
Dataset: {display_name} ({source_type}, {N} tables, ~{rows} rows, {date_range}) | not configured
Profile: {role}, {detail_level} | new
Integrations: {preferred_format}, {N} channels | not configured
Org: {company} ({industry}), {N} glossary, {N} products, {N} metrics | not configured
Corrections: {N} logged ({N} critical, {N} high) | none
Learnings: {N}/{6} categories populated | not yet populated
Archaeology: {N} cookbook, {N} cheatsheets, {N} join patterns | not yet populated
Archive: {N} analyses, {N} recurring patterns | none
Then output the user-facing status:
Dataset: {display_name} ({source_type})
Tables: {N} tables, ~{row_count} rows
Date range: {date_range}
Metrics: {M} defined
Profile: {loaded | new}
Status: Ready for analysis
If a critical subsystem is missing (no dataset, no manifest), adjust the status
and suggest /connect-data or /setup.

<!-- Format: YYYY-MM-DD | What was wrong | What was right -->
Edge Cases
- No
.knowledge/ dir: Create full tree and prompt /connect-data.
- Empty schema.md: Regenerate via profiling.
- No data files: Suggest checking connection or falling back to CSV.
- Multiple datasets: Report active, remind about
/switch-dataset.
- Setup incomplete: Note phases, do not block. Suggest
/setup.
Anti-Patterns
- Never skip bootstrap. Always read manifest -- details may have changed.
- Never hardcode dataset names. Resolve from
active.yaml.
- Never modify manifest during bootstrap. Bootstrap is read-only.
- Never dump raw YAML to the user. Show the brief status, not the load.
- Never block on a missing subsystem. Graceful degradation always.
