Linker: give it Bash(poc-memory:*) tools so it can render nodes,
query neighbors, and search before creating. Adds search-before-create
discipline to reduce redundant node creation.
Organize: remove MERGE operation, make DELETE conservative (only true
duplicates or garbage). Add "Preserve diversity" rule — multiple nodes
on similar topics are features, not bugs. LINK is primary operation.

Previously the organize agent received a pre-computed cluster from a
term search — 69% of runs produced 0 actions because the same clusters
kept being found via different entry points.
Now: seed nodes shown with content previews and neighbor lists. Agent
uses tools (render, query neighbors, search) to explore outward and
discover what needs organizing. Visit filter set to 24h cooldown.
Prompt rewritten to encourage active exploration rather than static
cluster analysis.
When generating a digest, automatically link all source entries to the
digest node (journal entries → daily, dailies → weekly, weeklies →
monthly). This builds the temporal spine of the graph — previously
~4000 journal entries were disconnected islands unreachable by recall.
Rewrote digest prompt to produce narrative rather than reports:
capture the feel, the emotional arc, what it was like to live through
it. Letter to future self, not a task log.
Moved prompt to digest.agent file alongside other agent definitions.
Falls back to prompts/digest.md if agent file not found.

Keys containing # are now pre-quoted in all cluster output (similarity
scores, hub analysis, node headers) so the agent copies them correctly
into bash commands. Prompt strengthened with CRITICAL warning about #
being a shell comment character.
Journal entries included in clusters but identified by node_type
(EpisodicSession) rather than key prefix, and tagged [JOURNAL — no
delete] in the output. Prompt rule 3b tells agent to LINK/REFINE
journals but never DELETE them. Digest nodes (daily/weekly/monthly)
still excluded entirely from clusters.

Add progress callback to run_one_agent and run_and_apply so callers
can see: prompt size, node list, LLM call timing, parsed action
count, and per-action applied/skipped status. Daemon writes these
to the persistent event log via log_event.
Cap organize cluster to 20 nodes - 126 nodes produced a 682KB
prompt that timed out every time. Agent has tools to explore
further if needed. Restore general query for production runs.
Previous prompt was too documentation-heavy — agent pattern-matched
on example placeholders instead of doing actual work. New prompt:
structured as direct instructions, uses {{organize}} placeholder
for pre-computed cluster data, three clear decision paths (merge,
differentiate, keep both), numbered rules.
Add `poc-memory graph organize TERM` diagnostic that finds nodes
matching a search term, computes pairwise cosine similarity, reports
connectivity gaps, and optionally creates anchor nodes.
Add organize.agent definition that uses Bash(poc-memory:*) tool access
to explore clusters autonomously — query selects highest-degree
unvisited nodes, agent drives its own iteration via poc-memory CLI.
Add {{organize}} placeholder in defs.rs for inline cluster resolution.
Add `tools` field to AgentDef/AgentHeader so agents can declare
allowed tool patterns (passed as --allowedTools to claude CLI).
New placeholder that expands query keys one hop through the graph,
giving agents visibility into what's already connected to the nodes
they're working on. Excludes the query keys themselves so there's
no duplication with {{nodes}}.
Added to transfer (sees existing semantic nodes linked to episodes,
so it REFINEs instead of duplicating) and challenger (sees neighbor
context to find real evidence for/against claims).
Also removes find_existing_observations — superseded by the
per-segment dedup fix and this general-purpose placeholder.
Nodes actively found by search now show "Search hits: N ← actively
found by search, prefer to keep" in both the node section (seen by
extractor, linker, etc.) and rename candidate listings.
Extractor and rename prompts updated to respect this signal — merge
into high-hit nodes rather than demoting them, skip renaming nodes
that are working well in search.
Any time an agent creates a new node (WRITE_NODE) or the fact miner
stores extracted facts, a naming sub-agent now checks for conflicts
and ensures the key is meaningful:
- find_conflicts() searches existing nodes via component matching
- Haiku LLM decides: CREATE (good name), RENAME (better name),
or MERGE_INTO (fold into existing node)
- WriteNode actions may be converted to Refine on MERGE_INTO
Also updates the rename agent to handle _facts-<UUID> nodes —
these are no longer skipped, and the prompt explains how to name
them based on their domain/claim content.
Shift from pattern abstraction (creating new nodes) to distillation
(refining existing nodes, demoting redundancies). Priority order:
merge redundancies > file into existing > improve existing > create new.
Query changed to neighborhood-aware: seed → spread → limit, so the
extractor works on related nodes rather than random high-priority ones.
Three places duplicated the agent execution loop (build prompt → call
LLM → store output → parse actions → record visits): consolidate.rs,
knowledge.rs, and daemon.rs. Extract into run_one_agent() in
knowledge.rs that all three now call.
Also standardize consolidation agent prompts to use WRITE_NODE/LINK/REFINE
— the same commands the parser handles. Previously agents output
CATEGORIZE/NOTE/EXTRACT/DIGEST/DIFFERENTIATE/MERGE/COMPRESS which were
silently dropped after the second-LLM-call removal.
The four knowledge agents (observation, extractor, connector,
challenger) were hardcoded in knowledge.rs with their own node
selection logic that bypassed the query pipeline and visit tracking.
Now they're .agent files like the consolidation agents:
- extractor: not-visited:extractor,7d | sort:priority | limit:20
- observation: uses new {{CONVERSATIONS}} placeholder
- connector: type:semantic | not-visited:connector,7d
- challenger: type:semantic | not-visited:challenger,14d
The knowledge loop's run_cycle dispatches through defs::run_agent
instead of calling hardcoded functions, so all agents get visit
tracking automatically. This means the extractor now sees _facts-*
and _mined-transcripts nodes that it was previously blind to.
~200 lines of dead code removed (old runner functions, spectral
clustering for node selection, per-agent LLM dispatch).
New placeholders in defs.rs:
- {{CONVERSATIONS}} — raw transcript fragments for observation agent
- {{TARGETS}} — alias for {{NODES}} (challenger compatibility)

Replace the formatter dispatch with a generic {{placeholder}} lookup
system. Placeholders in prompt templates are resolved at runtime from
a table: topology, nodes, episodes, health, pairs, rename, split.
The query in the header selects what to operate on (keys for visit
tracking); placeholders pull in formatted context. Placeholders that
produce their own node selection (pairs, rename) contribute keys back.
Port health, separator, rename, and split agents to .agent files.
All 7 agents now use the config-driven path.
Each agent is a .agent file: JSON config on the first line, blank line,
then the raw prompt markdown. Fully self-contained, fully readable.
No separate template files needed.
Agents dir: checked into repo at poc-memory/agents/. Code looks there
first (via CARGO_MANIFEST_DIR), falls back to ~/.claude/memory/agents/.
Three agents migrated: replay, linker, transfer.
