keephive 0.12.7

A knowledge sidecar for Claude Code

keephive

A knowledge sidecar for Claude Code. It captures what you learn, verifies it stays true, and surfaces it when relevant.

Claude Code forgets everything between sessions. keephive rides alongside it using hooks, an MCP server, and context injection to give it persistent, verified memory.

Install

uv tool install keephive
keephive setup

Requires uv. This installs from PyPI, registers the MCP server, and configures Claude Code hooks.

Via pip:

pip install keephive
keephive setup

From source:

git clone https://github.com/joryeugene/keephive.git
cd keephive && uv tool install . && keephive setup

Stay up to date

hive up                    # upgrade in place (recommended)
uv tool upgrade keephive   # manual alternative; run keephive setup after

Run keephive setup again after upgrading manually to sync hooks and the MCP server registration to the new binary path.

Quick start

hive r "FACT: Auth service uses JWT with RS256"   # remember something
hive v                                             # verify stale facts
hive go                                            # launch interactive session
hive todo                                          # open TODOs

After a few sessions, hive s shows what your agent has learned:

$ hive s
keephive v0.12.2
  ● hooks  ● mcp  ● data

  4 facts (4 ok) | 12 today | 8 yesterday | 2 guides | 48K

  1 open TODO(s):
    [today] Add rate limiting to the /upload endpoint.

  Today:
  ~ [10:42:15] FACT: Auth service uses JWT with RS256, tokens expire after 1h.
  ~ [10:38:01] DECISION: Chose Postgres over SQLite for multi-user support.
  ~ [09:15:44] INSIGHT: The retry logic in api_client.py silently swallows 429s.
  [09:12:30] DONE: Migrate user table to new schema.

How it works

keephive uses the three extension points Claude Code exposes:

1. Hooks fire on events (session start, conversation compact, user prompt). They capture insights and inject context without any agent action.
2. MCP server gives Claude Code native tool access (hive_remember, hive_recall, etc.) so the agent can read and write memory directly.
3. Context injection surfaces verified facts, behavioral rules, stale warnings, matching knowledge guides, and open TODOs at the start of every session via the SessionStart hook's additionalContext field.

The capture/verify/correct loop

  capture --> store --> verify --> correct
     ^                               |
     +-------------------------------+

• Capture: The PreCompact hook extracts FACT/DECISION/TODO/INSIGHT entries when conversations compact. It reads the full transcript, classifies insights via LLM, and writes them to today's daily log.
• Store: Entries land in daily logs and get promoted to working memory. Knowledge guides hold deep reference on specific topics.
• Verify: Facts carry [verified:YYYY-MM-DD] timestamps. After 30 days (configurable), they are flagged stale. hive v checks them against the codebase with LLM analysis and tool access.
• Correct: Invalid facts get replaced with corrected versions. Valid facts get re-stamped. Uncertain facts get flagged for human review.

Features in depth

Reflect

hive rf scans daily logs for recurring patterns across multiple days. When it finds a theme, hive rf draft <topic> generates a knowledge guide from the matching entries. This is how scattered daily notes become structured reference material.

Audit

hive a runs three parallel LLM analyses on your memory state (fact accuracy, data hygiene, strategic gaps), then synthesizes them into a quality score with actionable suggestions.

Standup

hive su generates a standup summary from recent daily log activity and optionally includes GitHub PR data.

Notes

hive n is a multi-slot scratchpad. Each slot persists across sessions, auto-copies to clipboard on save, and can be initialized from a prompt template (hive n <template>). Use hive n.2 to switch slots.

Prompts

hive p lists reusable prompt templates stored in knowledge/prompts/. Use them to start notes (hive n <template>) or launch custom sessions (hive session <template>).

Stats

hive st shows usage statistics with per-project breakdown, session streaks, and activity sparklines.

Smart Recall

hive rc <query> uses an SQLite FTS5 index over all daily logs and the archive for ranked full-text search. Run hive gc to rebuild the index. Falls back to grep if the index is absent.

Log Summarize

hive l summarize pipes today's log entries to claude-haiku and prints 3-5 bullet-point highlights. Useful after long sessions before compaction.

Edit

hive e <target> opens files in $EDITOR. Targets: memory, rules, todo (with diff-on-save), CLAUDE.md, settings, daily log, notes. Run hive e with no arguments to see all targets.

Sessions

hive go launches an interactive Claude session with your full keephive context pre-loaded.

Command	What
hive go	General session with full memory and warnings
hive session todo	Walk through open TODOs one by one
hive session verify	Check stale facts against the codebase
hive session learn	Active recall quiz on recent decisions
hive session reflect	Pattern discovery from daily logs
hive session <prompt>	Load a custom prompt from knowledge/prompts/

MCP tools

All commands are also available as MCP tools for Claude Code to call directly:

hive_remember, hive_recall, hive_status, hive_todo, hive_todo_done, hive_knowledge, hive_knowledge_write, hive_prompt_write, hive_mem, hive_rule, hive_log, hive_audit, hive_recurring, hive_stats, hive_fts_search

Configuration

Variable	Default	Description
HIVE_HOME	~/.claude/hive	Data directory
HIVE_STALE_DAYS	30	Days before a fact is flagged stale
HIVE_CAPTURE_BUDGET	4000	Characters to extract from transcripts
ANTHROPIC_API_KEY	(unset)	Direct API calls instead of claude -p
NO_COLOR	(unset)	Disable terminal colors

Development

uv run pytest                          # all tests
uv run pytest -m llm -v -o "addopts="  # LLM E2E tests (slow, real API calls)
uv run pytest -x                       # stop on first failure
