its-over-9k (o9k)
What does the scouter say about his context level? IT'S OVER 9000!!!

o9k is the connector between AI coding agent frameworks. It invents no
technique of its own. It decides which installed framework owns which concern,
wires them into every host, and keeps their interplay efficient. Primary
packaging is a Claude Code marketplace; the same pillars also wire into
Cursor, Codex, OpenCode, and Hermes via /o9k-init.
Every framework below saves tokens or improves output on its own. Combined
naively, they fight each other — two plugins hooking SessionStart, two output
styles rewriting your prose, two "plans" claiming to be the source of truth.
o9k's job is the arbitration layer: each concern has exactly one owner, and
the pieces multiply instead of colliding.
Everything is opt-in. o9k-core is the connector itself and the only piece
the others assume. Every other pillar is a separate yes/no in /o9k-init, with
a plain statement of who it's for and who should skip it. A machine running
core plus one pillar is a correct install, not a partial one.
The pillars
o9k-core is required. The rest are opt-in — /o9k-init asks about each one
separately and defaults to no.
Pillar | Plugin | Who it's for | Skip it if |
Doctrine & arbitration |
| Everyone. The arbitration table, host wiring, and the | — |
Context discipline |
| People working in real codebases, especially large or unfamiliar ones. Search before read, one canonical repo map per session. | Your sessions touch few files, or your work isn't code. |
Subagent isolation |
| Work with broad sweeps — repo-wide searches, log analysis, digesting long docs. Subagents return conclusions, not transcripts. | Short, single-file sessions; a subagent then costs more than it saves. |
Memory |
| Projects spanning many sessions. Briefing at session start, recall on demand, flush before compaction. | One-off tasks, or you don't want a memory MCP (TIM / hmem) installed. |
Discovery |
| People who curate their tool stack — scouting new frameworks, installing companion bundles. | Your stack is settled. Install it the day you go shopping. |
Spun out of o9k
o9k connects frameworks; it does not ship features of its own. These used to be
pillars and now live in their own repos. /o9k-init offers each one with the
same for/skip framing, and o9k keeps arbitrating their concerns.
Package | Concern | Who it's for |
caveman (upstream, not ours) | output style | Long sessions where the agent's own prose is a real share of the context. ~65% measured output reduction; code, commands and error strings stay verbatim. Disable its |
multi-agent roster | Driving several CLIs/models at once: role→model fallback chains, usage collector, limit watch, cross-CLI mailbox runs. See docs/MULTI-AGENT.md. | |
status bar | Model, context fill, limit headroom, git and memory project at a glance in Claude Code, Cursor or Hermes. | |
file attribution | Repos filling up with agent-written HANDOFF/PLAN/RESULT files, where you later need to know who wrote what and why. | |
benchmarking | Maintainers who want pass-count and cost numbers for a companion combo instead of README claims. |

Why combining multiplies
Less output → less context. Everything the agent says gets fed back into every later turn. caveman-style output doesn't just save this turn's tokens — it shrinks every future turn and delays compaction.
Less context → better memory. What scout refuses to load blindly never has to be summarized away. What dispatch isolates in a subagent never pollutes the main context. Compaction fires later, loses less.
Memory → less re-reading. A 300-token briefing from the memory backend replaces the 20k tokens of "let me look around the codebase" that every fresh session burns.
Together: the agent's effective context — the fraction doing useful work — goes way past what any single technique achieves. It's over 9000.
Zero effort by design
The human should not have to do — or know — anything. After install, a
SessionStart hook in o9k-core injects the doctrine automatically every
session: the agent compresses its output, loads only what it needs, offloads
noisy searches, and saves state before compaction — no commands, no reading,
no habits to learn.
What automation can't do (a one-time hmem init, disabling legacy superpowers
dispatch skills if still active), the agent handles conversationally:
/o9k-init is the guided setup — it detects what's already on the
machine, asks which companion bundle you want, installs git if you're missing
it, and when something you already run collides with a bundle pick it explains
why the pick is better and migrates your data before uninstalling anything
(your call, either way). On the very first session the agent offers it
automatically, and /o9k-guide brings back a one-minute orientation any
time. The guide is personalized — it detects your actual setup and
mentions only what's missing, offering to fix each item for you. A fully set-up
install gets three sentences: everything runs by itself, nothing to do,
/o9k-stats shows the effect.
Platforms
OS | o9k pillars | team-up companion (multi-agent) |
Linux | ✅ full | ✅ full |
macOS | ✅ full | ⚠️ needs |
Windows | ✅ full | ❌ tmux/bash stack — use WSL |
/o9k-init prints this as a Platform line first and skips setup questions the
host OS can't honor.
Install
Fast path (npm — Cursor, Codex, OpenCode, Hermes, and a global CLI):
npm i -g its-over-9k && o9k setupo9k setup wires shared skills and session hooks for every detected host.
Then optionally install a memory backend (or pick one in /o9k-init):
npm install -g tim-cli && tim init # preferred
# or: npm install -g hmem-mcp && hmem init(Scoped alias @bumblebiber/o9k is prepared in-repo; install via its-over-9k
until the scoped name is publicly resolvable on the registry.)
Claude Code (in-session marketplace):
/plugin marketplace add Bumblebiber/its-over-9k
/plugin install o9k-core@o9ko9k-core is all you install by hand. Run /o9k-init next — it walks the
optional pillars one at a time, tells you who each is for and who should skip
it, and installs only what you say yes to.
Then run /o9k-init in a session — it detects your setup, walks you
through the companion bundle choice, and handles conflicts and migration.
Works with Claude Code, Codex, Cursor, OpenCode, and Hermes on the same
machine: /o9k-init (or o9k setup) syncs shared o9k skills and wires session
hooks on every detected host (it never installs missing CLI binaries — see the
o9k-init skill).
TIM (npm tim-cli) and hmem
(npm hmem-mcp) are both supported
memory backends. /o9k-init asks which to install (or wire a custom MCP).
o9k-memory auto-detects and prefers TIM when tim is on PATH (or TIM_CLI
is set); otherwise it uses hmem. Track TIM at
Bumblebiber/tim.
Migrating from its-over-9k@1.x (clean reinstall)
1.x was the old hmem CLI (bin: hmem / hmem-curate), not this
meta-framework. Do a clean swap — do not leave the old global install in place:
npm uninstall -g its-over-9k
npm install -g hmem-mcp && hmem init # memory backend (replaces 1.x)
npm install -g its-over-9k@latest && o9k setupAfter that, which o9k should point at the new CLI and which hmem at
hmem-mcp. If either still points at a stale path, clear your shell hash
(hash -r) or open a new terminal.
One command for the companions
Don't hand-install the third-party frameworks below. o9k-recon ships a
bundle installer that wires up a whole tested stack at once:
/plugin install o9k-recon@o9kthen run the companion-bundles skill (or install/o9k-companions.sh recommended --run). Bundles: minimal, recommended, max — see
docs/BUNDLES.md.
Doctor & uninstall
o9k writes symlinks, rules, and hook wrappers across host config dirs — two scripts keep that auditable:
node plugins/o9k-core/scripts/o9k-doctor.mjs # read-only: list artifacts, flag dangling/stale
node plugins/o9k-core/scripts/o9k-uninstall.mjs --dry-run # then --run to remove themThe doctor flags dangling skill symlinks and wrappers whose baked marketplace
path no longer exists (e.g. after moving the clone — fix via
update-check.mjs --refresh-hosts). Uninstall removes only provably-o9k
artifacts, strips o9k entries from host hook configs without touching foreign
ones, keeps ~/.o9k user data, and prints the manual follow-ups
(/plugin uninstall, systemd/launchd units).
Playing with others
o9k deliberately does not re-implement workflow methodology, issue tracking, docs injection, or symbol-level navigation — excellent frameworks exist for those. This matrix covers every o9k-compatible companion and how each pair gets along:
🟢 complement each other — worth more together than apart
⚪ don't touch — no interaction, safe by construction
⚠️ one rule needed — works once you name a single owner (see notes)
🔴 block each other — same concern, never both active

o9k × superpowers:
o9k-dispatchowns subagent isolation by default; superpowers owns methodology. Disable stockdispatching-parallel-agentsonly if it is still enabled.superpowers × beads/task-master: a plan store beats plan files — the store owns plans, disable superpowers' plan markdown. One plan owner.
plan stores × memory: the store owns work items, memory owns lessons/decisions. Never track the same work in both.
Grouped entries block each other too — BMAD, spec-kit, and SuperClaude all claim the methodology spine; any two of them collide.
Not in the matrix — replacements, not companions. Some frameworks claim a concern an o9k pillar owns; they never share a setup with o9k, so their pairings are moot. Run them instead of the pillar they displace, or not at all: claude-mem / mem0 (vs the memory backend), Graphify / claude-context / codebase-memory-mcp (vs scout's overview), token-optimizer-mcp (vs caveman+scout).
Full per-framework notes and install mechanisms:
docs/COMBINING.md. The same facts exist
machine-readable as a compatibility layer
(plugins/o9k-core/compat/registry.json): detection, arbitration, and the
export-first migration driver (o9k-migrate.mjs) are all registry-driven —
/o9k-init uses it to detect rivals, argue the trade-off, and migrate data
before anything is uninstalled.
Scouting for new frameworks
The ecosystem moves weekly (9,000+ marketplace entries and climbing). o9k-recon
ships framework-scout — a GitHub Scout skill that tells the agent where
to hunt (Trending, Topics, the plugin directory, awesome-lists), how to score a
candidate (concern → stars → freshness → license → install mechanism), and how
to slot it into the matrix above (symbiotic / orthogonal / blocking) before
proposing a bundle or matrix update. See
plugins/o9k-recon/skills/framework-scout/SKILL.md.
Status
Early but functional. Five pillars (one required, four opt-in); hooks and multi-CLI wiring ship for the hosts above.
SessionStart (o9k-core) — injects a ~70-token doctrine directive (never documentation) so all installed pillars apply automatically; flags open arbitrations; offers
/o9k-guideonce on the first session. Disable viaO9K_CORE_HOOK=off.SessionStart update check (o9k-core) — reports which pillars/companions are updatable, instantly from a cache; the actual version check runs detached in the background (once per
O9K_UPDATE_INTERVAL_HOURS, default 24h), so it never slows session start.O9K_UPDATE_CHECK=notify(default) reports;autoalso applies the safe npm-global updates (companions +its-over-9kwhen installed via npm);offdisables. Claude marketplace plugins stay notify-only — never clobbered. After/plugin marketplace update o9kornpm i -g its-over-9k@latest, run/o9k-update --refresh-hosts(npm--applyalready refreshes hosts whenits-over-9kitself was updated).SessionStart (o9k-memory) — detects the memory backend (TIM via
tim resolve-project, else hmem) and injects a compact loading directive (never memory content). Stays silent if the backend's own hooks are already installed — one owner per concern. Disable viaO9K_MEMORY_HOOK=off.PreCompact (o9k-memory) — fires the backend's checkpoint (
tim checkpoint/hmem checkpoint) in the background before compaction summarizes the session away. Never blocks or delays compaction.Multi-agent (team-up, separate package) — limit watch, subscription usage collector, and cross-CLI mailbox runs live in team-up. o9k arbitrates the concern and requires
dispatchpath B once a roster exists; it ships none of that code. See docs/MULTI-AGENT.md.
o9k-core also ships /o9k-guide (personalized setup orientation backed by
a read-only detector script), /o9k-update (check pillars & companions for
newer versions and apply the safe ones), and /o9k-stats: a zero-dependency
analyzer over Claude Code's session transcripts — output share, cache hit
profile, avg output per turn — so the savings are measured, not vibes.
