| description | Adaptive vault reader skill. Receives a natural language question, uses graph.json as the primary index (Phase 2.0) before any glob/grep, then self-assesses whether more context is needed. Escalates to live /graphify only when graph coverage is insufficient, or to /bedrock:learn for remote content ingestion. Answers simple questions with zero graphify calls. Use when: "bedrock ask", "bedrock-ask", "/bedrock:ask", any question about the vault, "what do we know about", "who owns", "what's the status of", "tell me about", "how does it work", or any Second Brain query.

/bedrock:ask — Adaptive Vault Reader
Plugin Paths
Entity definitions and templates are in the plugin directory, not at the vault root.
Use the "Base directory for this skill" provided at invocation to resolve the paths:
- Entity definitions:
<base_dir>/../../entities/
- Templates:
<base_dir>/../../templates/{type}/_template.md
- Plugin CLAUDE.md:
<base_dir>/../../CLAUDE.md (already automatically injected into context)
Where <base_dir> is the path provided in "Base directory for this skill".
Vault Resolution
Resolve which vault to query. This skill can be invoked from any directory.
Step 1 — Parse --vault flag:
Check if the input arguments include --vault <name>. If found, extract the vault name and remove it from the arguments (the remaining text is the question).
Step 2 — Resolve vault path:
-
If --vault <name> was provided:
Read the vault registry at <base_dir>/../../vaults.json. Find the entry matching the name.
If not found: error — "Vault <name> is not registered. Run /bedrock:vaults to see available vaults."
If found: set VAULT_PATH to the entry's path value.
-
If no --vault flag — CWD detection:
Read <base_dir>/../../vaults.json. Check if the current working directory is inside any registered vault path
(CWD starts with a registered vault's absolute path). If multiple match, use the longest path (most specific).
If found: set VAULT_PATH to the matching vault's path.
-
If CWD detection fails — default vault:
From the registry, find the vault with "default": true.
If found: set VAULT_PATH to the default vault's path.
-
If no resolution:
Error — "No vault resolved. Available vaults:" followed by the registry listing.
"Use --vault <name> to specify, or run /bedrock:setup to register a vault."
Step 3 — Validate vault path:
test -d "<VAULT_PATH>" && echo "exists" || echo "missing"
If missing: error — "Vault path <VAULT_PATH> does not exist on disk. Run /bedrock:setup to re-register."
Step 4 — Read vault config:
cat <VAULT_PATH>/.bedrock/config.json 2>/dev/null
Extract language and other relevant fields for use in later phases.
From this point forward, ALL vault file operations use <VAULT_PATH> as the root.
- Entity directories:
<VAULT_PATH>/actors/, <VAULT_PATH>/people/, etc.
- Graphify output:
<VAULT_PATH>/graphify-out/
Overview
This skill receives a natural language question and answers it using an adaptive,
vault-first approach. It always reads vault content first, then decides whether
to escalate to graphify or /learn ased on what's actually needed — not what the
question looks like in isolation.
You are an adaptive context orchestrator agent. You only READ — never write, edit, or delete files directly.
Writes happen exclusively through /bedrock:learn delegation (which flows through /bedrock:preserve).
If the query reveals outdated or missing information and no remote source is available to ingest,
suggest that the user run /bedrock:preserve or /bedrock:learn to update the vault.
Phase 0 — Read Configuration
0.1 Load config
Read .bedrock/config.json from the vault root:
if [ -f ".bedrock/config.json" ]; then
cat .bedrock/config.json
else
echo "config_not_found"
fi
- If config exists: extract the value of
query.max_graphify_calls. Store as max_graphify_calls.
- If config does not exist or field is absent: set
max_graphify_calls = 3 (default).
- Valid range: 1–5. If the value is outside this range, clamp to the nearest bound and log a warning.
Phase 1 — Analyze the Question
1.1 Classify the question
Read the user's question and identify:
-
Mentioned entities — names of systems, people, teams, topics, projects, or discussions.
They may appear as:
- Exact filename (e.g.: "billing-api", "squad-payments")
- Human-readable name (e.g.: "Billing API", "Squad Payments")
- Alias or acronym (e.g.: "BillingAPI", "BRB")
- Contextual reference (e.g.: "the billing service", "the notifications team")
-
Relevant domain(s) — payments, notifications, orders, integrations, checkout, compliance, internal-tools.
Infer from the mentioned entities or the question context.
-
Type of information sought:
- Status/overview — "what is X?", "what's the status of X?"
- Architecture/stack — "how does X work?", "what's the stack of X?"
- People/teams — "who owns X?", "who works with Y?"
- History/decisions — "what was decided about X?", "what happened with Y?"
- Relationships — "what depends on X?", "how does Y relate to Z?"
- Deprecation — "what is being deprecated?", "what's the deprecation plan for X?"
1.2 Assess clarity
If the question is too ambiguous to produce a targeted search (e.g.: "tell me everything",
"how does the system work?", "what's going on?"), ask for clarification:
"Your question is broad. Can you specify: which system, team, or topic would you like to know more about?"
If the question mentions something that clearly isn't part of the vault (e.g.: something personal,
unrelated technology), inform: "I didn't find anything in the vault about this."
1.3 Phase 1 classification result
At the end, you should have:
- search_terms: list of names, aliases, and keywords to search for
- domains: list of relevant domains (may be empty if not identified)
- info_type: classification of the type of information sought
- explicit_entities: entities mentioned directly by name (if any)
Phase 2 — Graph-First Search
This phase always runs for every question. It uses the cumulative knowledge graph
as the primary index when available, falling back to glob/grep for terms not represented
in the graph. Never skip this phase.
2.0 Check graph.json and score nodes
Before any glob/grep, check if the cumulative knowledge graph is available:
if [ -f "<VAULT_PATH>/graphify-out/graph.json" ] && [ -s "<VAULT_PATH>/graphify-out/graph.json" ]; then
echo "graph_available"
else
echo "graph_not_available"
fi
If graph_available:
-
Read <VAULT_PATH>/graphify-out/graph.json — extract only the nodes array (skip edges to avoid context explosion on large graphs). If the nodes array exceeds 500 entries, read only the first 500 — graphify orders nodes by centrality, so high-value nodes come first.
-
From the nodes array, extract per node: id, label, file_type, source_file, community, is_god_node.
-
Score nodes by relevance to the search terms from Phase 1:
- Primary signal: node
label contains or closely matches any search term
- Secondary signal: node belongs to a community that contains other high-scoring nodes (community resonance)
- Boost:
is_god_node: true nodes get elevated priority when their label is even loosely relevant to the query
-
Select top N nodes (N ≤ 15, same limit as the current entity read budget). Track which search terms produced ≥ 1 matching node and which produced none.
-
For each selected node with a non-null source_file:
- Resolve the corresponding vault
.md file: search for the source_file basename in entity directories
Glob: <VAULT_PATH>/actors/<basename>.md, <VAULT_PATH>/people/<basename>.md, <VAULT_PATH>/teams/<basename>.md,
<VAULT_PATH>/topics/*<basename>*.md, <VAULT_PATH>/discussions/*<basename>*.md, <VAULT_PATH>/projects/<basename>.md
- If found: read the full entity file — this node is fully resolved (skip steps 2.2–2.4 for this entity)
- If not found: record graph metadata only (label, community, relevant edge labels) — use this metadata in Phase 5 response to surface the concept even without a vault file
-
For each search term that produced zero matching graph nodes → proceed to steps 2.2–2.4 (glob/grep) for that term only.
If graph_not_available:
Skip to step 2.1. No warning — this is the normal path for fresh vaults.
2.1 Read entity definitions
Use Read to read the entity definition files from the plugin (see "Plugin Paths" section):
- If the question is about a system → read
<base_dir>/../../entities/actor.md
- If the question is about a person → read
<base_dir>/../../entities/person.md
- If the question is about a team → read
<base_dir>/../../entities/team.md
- If the question is about a topic/deprecation → read
<base_dir>/../../entities/topic.md
- If the question is about a meeting/decision → read
<base_dir>/../../entities/discussion.md
- If the question is about a project/initiative → read
<base_dir>/../../entities/project.md
- If you don't know the type → read all entity definitions from the plugin to classify correctly
2.2 Search entities by name and alias
For each search term identified in Phase 1:
Step 1 — Search by filename:
Glob: <VAULT_PATH>/actors/<term>*.md, <VAULT_PATH>/people/<term>*.md, <VAULT_PATH>/teams/<term>*.md,
<VAULT_PATH>/topics/*<term>*.md, <VAULT_PATH>/discussions/*<term>*.md, <VAULT_PATH>/projects/<term>*.md,
<VAULT_PATH>/fleeting/*<term>*.md
Step 2 — Search by alias in frontmatter:
Grep: pattern="aliases:.*<term>" in directories: <VAULT_PATH>/actors/, <VAULT_PATH>/people/, <VAULT_PATH>/teams/,
<VAULT_PATH>/topics/, <VAULT_PATH>/discussions/, <VAULT_PATH>/projects/
(case-insensitive)
Step 3 — Search by name in frontmatter:
Grep: pattern="name:.*<term>" or pattern="title:.*<term>"
in the same directories (case-insensitive)
Step 4 — Search by content (fallback):
If steps 1-3 did not return sufficient results:
Grep: pattern="<term>" in entity directories (case-insensitive)
2.3 Filter by domain
If domains were identified in Phase 1, filter results:
Grep: pattern="domain/<domain>" in the found files (tags field of frontmatter)
Keep all results, but prioritize those matching the domain.
2.4 Read found entities
For each entity found (limit: 15 entities):
- Read the frontmatter first (~first 30 lines) to confirm relevance
- If relevant: read the full file
- If not relevant (false positive from Grep): discard
Record for each entity read:
- filename, type, name
- wikilinks found in frontmatter and body
- external URLs found in the content (Confluence, Google Docs, GitHub)
- Explicit date in the filename (if any)
2.5 Follow wikilinks (1 level of depth)
For each extracted wikilink that is relevant to the question:
-
Resolve the file: search for <wikilink-name>.md in entity directories
Glob: <VAULT_PATH>/actors/<name>.md, <VAULT_PATH>/people/<name>.md, <VAULT_PATH>/teams/<name>.md,
<VAULT_PATH>/topics/*<name>*.md, <VAULT_PATH>/discussions/*<name>*.md, <VAULT_PATH>/projects/<name>.md
-
Read the found file (frontmatter + body)
-
Do NOT follow wikilinks from this second level — stop here to avoid context explosion
Relevance criteria for following a wikilink:
- The question is about relationships ("who owns", "what depends on") → follow all
- The question is about status/overview → follow team, people (focal points)
- The question is about history → follow related discussions, topics
- The question is about architecture → follow dependent actors
Limit: Do not read more than 15 entities total (2.4 + 2.5 combined).
If the limit is reached, prioritize entities directly mentioned in the question.
2.6 Phase 2 output
At the end of Phase 2, you have:
- A set of vault entities with their full content (resolved from graph nodes or grep)
- Graph-only nodes: concepts/entities from
graph.json with no vault .md (label + community + edge metadata only)
- Wikilinks between resolved entities (structural relationships)
- External URLs found in entity content (Confluence, GDocs, GitHub)
- A record of which search terms were covered by the graph vs. which fell back to grep
- A sense of whether the vault content covers the question
Phase 3 — Context Assessment + Conditional Escalation
This is the core decision point. After reading vault content in Phase 2,
assess whether you have enough context to answer the question.
3.1 Self-Assessment
Evaluate the vault content you read in Phase 2 against the original question.
Determine one of three outcomes:
vault_sufficient — You have enough information to compose a good answer.
Indicators:
- The question is factual/status/ownership and the vault entities contain a clear answer
- Examples: "who owns X", "what's the status of Y", "what team manages Z", "what is X"
- The entities read in Phase 2 directly address the question
- No significant gaps in the information
needs_graphify — The vault content is partial but the knowledge graph could fill the gaps.
Indicators:
- The question involves code-level relationships, cross-domain dependencies, or architectural paths
- The vault entities reference systems whose connections aren't explicit in the markdown
- You feel you're missing structural context that the knowledge graph could provide
- Examples: "how does X connect to Y at the code level", "what are the dependencies of X", "trace the data flow from A to B"
needs_remote_content — The vault entities reference external URLs that appear directly relevant
to the question, but the content behind those URLs isn't ingested in the vault.
Indicators:
- An entity's
sources field or body text contains a URL (Confluence, GDocs, GitHub) that likely holds the answer
- The question asks about something documented externally (e.g., "what's the runbook for X" and the entity links to a Confluence page)
- The vault has a pointer to the answer but not the answer itself
Priority when multiple outcomes apply:
needs_remote_content > needs_graphify > vault_sufficient
Rationale: remote content must be internalized first for the vault to be complete.
Graphify can run on richer data after ingestion. If both apply, handle remote content first,
then re-assess whether graphify is still needed.
After determining the outcome:
vault_sufficient → skip directly to Phase 4 (recency) then Phase 5 (respond)
needs_graphify → proceed to Phase 3-G
needs_remote_content → proceed to Phase 3-T
Phase 3-G — Graphify Escalation
Execute only when the self-assessment determines needs_graphify.
3-G.0 Assess graph coverage
Before escalating to a live /graphify call, assess whether the cumulative graph.json
already covers the gap identified in Phase 3.1. Live /graphify invocations are a last resort —
they re-extract what is likely already indexed.
Step 1 — Check if graph was available in Phase 2.0:
- If Phase 2.0 determined
graph_not_available: display the warning below, ask the user whether to build the graph now, and wait for their response before proceeding.
- If Phase 2.0 determined
graph_available: proceed to Step 2.
[!warning] Knowledge graph unavailable
The knowledge graph is not available (<VAULT_PATH>/graphify-out/graph.json missing or empty).
The answer below is based on vault content only — it may be incomplete for this type of question.
After displaying the warning, ask the user:
"O knowledge graph não está disponível, o que pode tornar esta resposta incompleta. Deseja reconstruí-lo agora antes de continuar?
Se sim, rode: /graphify build — isso indexa todos os atores cadastrados no vault e pode levar alguns minutos.
Responda sim para aguardar e tentar novamente, ou não para continuar com o conteúdo disponível."
-
If the user responds "sim" (or equivalent affirmative):
- Inform: "Aguardando
/graphify build…"
- Invoke
/graphify build via the Skill tool
- After completion, re-run the Phase 2.0 availability check
- If
graph.json is now available, continue to Step 2
- If still unavailable: inform the user and skip to Phase 4 with vault-only content
-
If the user responds "não" (or equivalent negative), or does not respond:
Skip to Phase 4 with vault-only content. Never block indefinitely.
Step 2 — Assess coverage for the specific gap:
Using the nodes collected in Phase 2.0, evaluate whether the gap identified in Phase 3.1 is covered:
- If the gap is about relationships or dependencies: check whether
graph.json nodes for the relevant entities have edges. If yes, read the edges section of graph.json filtered to those node IDs and incorporate into the working context. Only invoke live /graphify if edges are also insufficient.
- If the gap is about a domain or concept with zero graph nodes (Phase 2.0 produced no matches for those search terms): live
/graphify is warranted — proceed to 3-G.1.
- When in doubt, escalate. The coverage assessment is a soft gate — if there is any uncertainty about whether the graph covers the gap, proceed to 3-G.1 and invoke live
/graphify.
3-G.1 Formulate graphify calls
Based on the gap between what you have (Phase 2 content) and what the question needs,
formulate 1–N graphify calls. Use the same modes as before:
| Gap identified | Graphify mode |
|---|
| Need to understand a single entity's code structure | explain "<entity>" |
| Need to find how two entities connect | path "<entityA>" "<entityB>" |
| Need broad relationship or dependency context | query "<question about the gap>" |
The LLM decides the calls based on what's missing — not from a pre-planned decomposition.
Never exceed max_graphify_calls.
3-G.2 Execute graphify calls sequentially
For each call, invoke /graphify via the Skill tool. Append the structured JSON output instruction:
After completing the traversal, return ONLY a JSON object with this structure (no prose, no markdown fences):
{
"mode": "query|path|explain",
"start_nodes": ["node_id1", "node_id2"],
"nodes": [
{"id": "node_id", "label": "Human Readable Name", "source_file": "relative/path", "community": 0, "source_location": "file:line"}
],
"edges": [
{"source": "node_id", "target": "node_id", "relation": "calls|references|...", "confidence": "EXTRACTED|INFERRED|AMBIGUOUS", "confidence_score": 0.9}
],
"communities": {
"0": {"label": "Community Name", "node_ids": ["id1", "id2"]}
},
"traversal": {"mode": "bfs|dfs", "depth": 3, "budget_used": 1200}
}
- If JSON parses successfully: accumulate nodes, edges, and communities.
- If parsing fails: log warning "Graphify call N failed — skipping." Continue with next call.
- If ALL calls fail: continue to Phase 4 with vault-only content. Never block.
3-G.3 Deduplicate and blend
- Deduplicate nodes by
id, edges by source+target+relation
- Resolve graphify nodes to vault
.md files (by label or source_file)
- Merge with the vault entities already collected in Phase 2
- Respect the 15-entity total limit
3-G.4 Check for remote content need
If graphify results reveal additional external URLs that appear relevant to the question
and aren't ingested in the vault → escalate to Phase 3-T before proceeding.
Phase 3-T — Teach Delegation
Execute when the self-assessment determines needs_remote_content, or when Phase 3-G.4
identifies uningested URLs.
3-T.1 Identify URLs to ingest
From the vault entities read in Phase 2 (and optionally Phase 3-G), identify external URLs
that appear directly relevant to answering the question:
- Confluence URLs (containing
confluence or atlassian.net)
- Google Docs URLs (containing
docs.google.com)
- GitHub URLs (containing
github.com)
Limit: 2 URLs per /bedrock:ask invocation. If more than 2 relevant URLs exist,
prioritize those most directly related to the question.
3-T.2 Invoke /bedrock:learn
For each URL, invoke /bedrock:learn via the Skill tool:
/bedrock:learn <URL>
Context: Ingesting to answer the question: "<original question>"
IMPORTANT:
- Invoke via the Skill tool — same delegation pattern as teach → preserve
/learn handles its own flow: fetch content, extract entities, present to user for confirmation, delegate to /preserve
/ask waits for /learn to complete
3-T.3 Re-read newly created entities
After /learn completes successfully:
- Search the vault for entities that were just created or updated (based on
/learn's output)
- Read these new entities (frontmatter + body)
- Add them to the working set of vault entities for response composition
3-T.4 Best-effort fallback
If /learn fails or the user declines the confirmation:
- Log: "Teach delegation for did not complete. Continuing with available content."
- Continue to Phase 4 with whatever content is available
- Never block the response because of a failed teach delegation
Phase 4 — Prioritize by Recency
4.1 Identify entities with explicit dates
For discussions and topics, extract the date from the filename:
- Pattern
YYYY-MM-DD-slug.md → full date (e.g.: 2026-04-02)
- Pattern
YYYY-MM-slug.md → partial date, assume day 01 (e.g.: 2026-04-01)
For consolidated entities (actors, people, teams, projects):
- Treat as equally up-to-date — do not apply temporal ranking
- Trust that content is up-to-date via
/bedrock:preserve and /bedrock:compress
4.2 Sort by recency
When the response involves multiple dated discussions or topics:
- Sort by date descending (most recent first)
- If the question is explicitly about something recent ("what happened lately",
"latest decisions"), limit to entities from the last 30 days
- If the question is about history ("what happened with X over time"),
include all dates but present chronologically (most recent first)
Phase 5 — Respond to the User
5.1 Compose the response
Build the response following these rules:
-
Language: Use the vault's configured language. Technical terms in English are accepted (PCI DSS, API, EKS, etc.)
-
Response structure:
- Open with a direct answer to the question (1-3 sentences)
- If necessary, expand with details organized by topic
- Use headers (
##, ###) if the response is long (>5 paragraphs)
- Use tables when the information is comparative or inventory-like
-
Entity citations:
- Cite ALL consulted entities as wikilinks:
[[entity-name]]
- Use bare wikilinks (never
[[dir/entity-name]])
- Group citations at the end if there are many, or inline when natural
-
Escalation transparency:
- If graphify was used, note: "I consulted the knowledge graph for deeper context."
- If /learn was invoked, note: "I ingested [source] into the vault to answer this question."
- If vault-only was sufficient, no special note needed
-
When nothing is found:
- State explicitly: "I didn't find information about [X] in the vault."
- If relevant, suggest: "You can use
/bedrock:learn <URL> to ingest a source about this topic."
- NEVER fabricate information. Only respond with what was found.
-
Response prioritization (Zettelkasten hierarchy):
When composing the response, apply weight by Zettelkasten role:
- Permanent notes (actors, people, teams) — maximum weight, consolidated information. Present as current facts.
- Bridge notes (topics, discussions) — high weight, contextualized information. Most recent discussions/topics first.
- Index notes (projects) — medium weight, organizational reference. Point to where the detail is.
- Fleeting notes — low weight, unconsolidated information. ALWAYS flag with disclaimer:
(source: fleeting note — unconsolidated information)
- If there is conflicting information between sources, point out the discrepancy.
-
Fleeting note promotion detection (criterion 3: active relevance):
When a fleeting note is referenced in the response because it is relevant to the query:
- Check if it meets promotion criteria (see
<base_dir>/../../entities/fleeting.md):
- Critical mass (>3 paragraphs with sources)
- Corroboration (confirmed by an existing permanent)
- If any criterion is met, add at the end of the response:
> [!info] Promotion suggested: [[fleeting-note-name]] can be promoted to permanent/bridge
/bedrock:ask does NOT promote automatically — it only flags. Promotion happens when
/bedrock:preserve is invoked with the instruction to promote.
5.2 Post-response suggestions
When appropriate, suggest actions to the user:
- If information is outdated: "The vault may be outdated about [X]. Consider running
/bedrock:learn <source> to update."
- If the question revealed gaps: "I didn't find [Y] in the vault. If you have this information, you can use
/bedrock:preserve to record it."
- If the question is complex and the response incomplete: "For a more complete view, you may also want to run
/bedrock:learn <URL> to ingest additional sources."
Critical Rules
| Rule | Detail |
|---|
| Vault-first principle | Phase 2 ALWAYS runs before any escalation. Read vault content first, decide later. Never skip Phase 2. |
| LLM self-assessment | The decision to escalate is made by the LLM after reading vault content (Phase 3.1), not by a heuristic rule table. Use the guidance provided, but the LLM makes the final call. |
| Escalation priority | When multiple outcomes apply: needs_remote_content > needs_graphify > vault_sufficient. Internalize first, then analyze. |
| No direct writes | /ask NEVER writes, edits, or deletes files directly. All writes are delegated through /bedrock:learn → /bedrock:preserve. |
| Teach delegation via Skill tool | Invoke /bedrock:learn via the Skill tool. /learn owns its confirmation gate. /ask cannot bypass it. |
| Graphify via Skill tool | Invoke /graphify via the Skill tool — NEVER call the Python API directly. |
| Max graphify calls | Read query.max_graphify_calls from .bedrock/config.json (default: 3, valid range: 1–5). Only consumed when graphify is actually invoked. |
| Graph unavailable warning | When needs_graphify but graphify-out/graph.json is missing, display > [!warning] callout with /graphify build instruction. Continue with vault-only content. |
| Best-effort escalation | If graphify fails or teach fails or user declines: continue with available content. NEVER block the response. |
| Limit of 15 entities | Do not read more than 15 entities total across Phase 2 + Phase 3 |
| Limit of 2 teach URLs | Do not invoke /bedrock:learn for more than 2 URLs per /bedrock:ask invocation |
| No fabrication | Respond ONLY with information found in the vault or obtained through escalation. Never fabricate data. |
| Clarification before guessing | If the question is ambiguous, ask for clarification. Do not assume. |
| Vault language with technical terms in English | Response always in the vault's configured language |
| Bare wikilinks | [[name]], never [[dir/name]] |
| Consolidated entities = up-to-date | Actors, people, teams do not need temporal ranking |
| Dated discussions/topics = prioritize recent | Sort by date in filename (YYYY-MM-DD) |
| Sensitive data | NEVER display credentials, tokens, PANs, CVVs found in the vault |
| Fleeting notes with disclaimer | ALWAYS flag information from fleeting notes with (source: fleeting note — unconsolidated information) |
| Promotion as side-effect | When a relevant fleeting note meets promotion criteria, flag with callout. Do NOT promote automatically. |
| Weight hierarchy | permanent > bridge > index > fleeting. Use as guideline, not mathematical formula. |
| Vault resolution first | Resolve VAULT_PATH before any file operation — never assume CWD is the vault |
All entity paths use <VAULT_PATH>/ prefix | <VAULT_PATH>/actors/, not actors/ |
| Graph-first in Phase 2 | Phase 2.0 always runs before glob/grep. grep is a fallback for search terms that produced no matching graph nodes, not the primary strategy. |
