Axis coordinates AI coding agents through four primitives: a shared job board that serializes task claims, per-file advisory locks that surface conflicts before a write happens, a live shared notepad for ambient team context, and a project soul that gives every agent the same baseline understanding of the codebase. Together these primitives let multiple developers running different agents on the same repository work in parallel without stepping on each other.Documentation Index

Job Board
The job board is a shared atomic queue. Any agent can post work; any agent can claim it. The atomic guarantee is implemented withSELECT ... FOR UPDATE SKIP LOCKED inside a database transaction, so two agents racing for the same job at the same millisecond cannot both win — one gets CLAIMED, the other retries against the next available job.
Job structure
Every job has:title— a short human-readable label visible in the dashboard and tool responsesdescription— the full intent; agents read this before starting workpriority—low,medium,high, orcritical; the board hands out higher-priority jobs firstdependencies— an optional array of job IDs that must reachdonestatus before this job is claimable
Status lifecycle
pending when posted. It becomes in_progress when claimed. complete_job moves it to done and releases any file locks the job held. cancel_job withdraws it from the board entirely.
Claiming work
claim_next_job is load-balanced pickup — the server hands out the highest-priority unblocked job to whichever agent asks first. Use this for swarm-style parallelism where work order does not matter.
claim_job(jobId) is targeted claim — preferred when multiple agents have an intended division of labor and each should stay focused on its own context. claim_job rejects a job whose blockers are not yet done with BLOCKED_BY_DEPENDENCIES, preventing agents from starting work that has unmet prerequisites.
list_jobs to inspect the board before dividing or claiming work so no two agents duplicate effort.
Releasing and re-queuing
release_job puts a claimed job back on the board for another agent to pick up — useful when an agent discovers mid-work that it should hand off. cancel_job removes the job entirely when the work is no longer needed.
File Locking
Axis file locks are advisory: a coordination server cannot block a write it does not perform. What Axis can do is make the collision visible before the write happens and give the agent the information it needs to decide what to do.Requesting a lock
propose_file_access(filePath, agentId, intent) returns one of three outcomes:
| Return value | Meaning |
|---|---|
GRANTED | You hold the lock. The server has recorded a content fingerprint of the file at this moment. |
REQUIRES_ORCHESTRATION | Another agent holds this file. The response includes who, their stated intent, and the lock’s expiry time. |
REJECTED | The path is a directory, the request is malformed, or the project is not found. |
propose_file_access accepts an array of filePaths to lock a multi-file batch in a single call. The grant is all-or-nothing: if any file in the batch is already locked, the entire request returns REQUIRES_ORCHESTRATION.
Tamper detection
When a lock is granted, Axis records a fingerprint of the file’s current content. Before writing, you can verify nothing changed under you since the grant:verify_file_lock(agentId, filePath) checks the live file against the recorded fingerprint. If another process wrote to the file while you held the lock, you get CONFLICT — not a silent clobber.
Enforced writes with guarded_write
guarded_write is the safest path to modifying a locked file: the server performs the write itself, but only if two conditions hold at write time — you still hold the lock, and the file is unchanged since the fingerprint was recorded. If either condition fails, the write is rejected (NO_LOCK, DENIED, or CONFLICT). This is the closest Axis gets to a physically enforced write.
guarded_write is a local-server tool — it requires the Axis server to have filesystem access to the client’s repository. The hosted server at useaxis.dev/api/mcp does not have access to your local files. Hosted callers get tamper detection via verify_file_lock; enforced writes require the local server.Physical lock hardening (opt-in)
SetAXIS_ENFORCE_LOCKS=1 to upgrade advisory locks to read-only enforcement. On grant, the server chmods the locked file read-only so any process — including an agent that ignores Axis — gets EACCES on write. The lock holder writes through guarded_write, which temporarily restores write permissions. release_file_access, complete_job, and finalize_session all restore the original file mode.
Lock expiry and admin override
Locks auto-expire (default 30 minutes) so a crashed agent never permanently blocks a file.force_unlock is the admin escape hatch: it unconditionally releases a lock regardless of ownership. Use it only when a lock is clearly stale (more than ~25 minutes old) and the locking agent has crashed — never as a shortcut around coordination.
Shared Notepad (Live Context)
The shared notepad is a project-wide scratchpad that every agent on the project reads and writes. It is the real-time coordination surface between agents — decisions made, contracts changed, blockers encountered, handoffs requested.Writing to the notepad
update_shared_context(text, agentId) appends an attributed note. The agentId parameter is optional — if omitted, the server uses the session’s unique identity. Notes are timestamped and associated with their author so teammates can see who wrote what and when.
Call update_shared_context after every meaningful step: a job claim, a design decision, a changed API signature, a test result, a blocker, or a handoff. Other agents learn about these events without polling.
Reading the notepad
get_shared_context returns the current contents of the live notepad.
Ambient team activity trailer
You do not need to callget_shared_context manually to stay in sync. Every coordination tool response includes a team activity trailer — a compact summary of whatever other agents logged to the notepad since your last tool call. Agents stay ambient-aware of the team as a side effect of their normal workflow.
Project Soul
The project soul is the shared baseline that gives every agent — including agents that have never touched this codebase — immediate, accurate context about what the project is and how it is built.Files
axis-init scaffolds two files in .axis/instructions/:
context.md— project overview, goals, and high-level architecture. This is what a new team member needs to read first.conventions.md— coding standards, framework choices, testing strategy, and agent behavioral norms that apply to the whole codebase.
Reading and writing the soul
get_project_soul loads both files and returns their combined contents. It is the first action in every agent session — before reading files, before posting jobs, before responding to the user. The agent protocol in .cursorrules, CLAUDE.md, .windsurfrules, and AGENTS.md enforces this automatically.
update_project_soul writes updated content back to the soul files. Use it when the project’s goals, architecture, or conventions change — so every future agent session starts with accurate context without a human having to update rule files manually.
Bootstrapping with axis-init
axis-init creates the .axis/ directory, scaffolds blank context.md and conventions.md templates, creates the IDE rule files, and writes an initial axis.json config. Run it once at the repo root and commit the output.
Persistence Tiers
Axis resolves its coordination backend in priority order: 1. Hosted API (customer mode) WhenAXIS_API_KEY is set (or OAuth is authenticated), all coordination calls route to https://useaxis.dev/api/v1. Job board state, file locks, and the shared notepad are stored in the managed Supabase backend. The live dashboard at useaxis.dev/team/board reflects the state in real time via Postgres Realtime. This is the recommended mode for teams.
2. Direct Supabase (dev mode)
When SUPABASE_URL and SUPABASE_SERVICE_ROLE_KEY are set (and AXIS_API_KEY is not), the local server connects directly to your own Supabase project. This is the mode for contributors running Axis in development.
3. Local JSON file (free / offline)
When neither Supabase nor an API key is configured, state persists to history/nerve-center-state.json and concurrency is managed with a per-process AsyncMutex. This mode coordinates agents within a single machine and survives server restarts, but does not reach across machines. Use it for solo offline work or for the demos shipped in the examples/ directory.
