Cirdan is an on-call software repair agent. A production alert fires — Grafana, Alertmanager, or Slack. Cirdan resolves the affected service and its repo from the explicit services: registry in cirdan.yaml, reproduces the failure in an isolated runner (Docker Compose or Kubernetes), has a coding agent fix the code — your own logged-in Claude Code / Codex CLI, or an API provider — re-verifies the fix against the pinned reproduction probe and the repo's test suite, and opens a verified pull request. When policy allows, it merges, deploys, and verifies production recovery, stopping at manual_required with full evidence when recovery fails.

alert ─▶ resolve service + repo (the services: registry) ─▶ reproduce in an isolated runner      ─▶ coding agent fixes the code ─▶ verify (pinned repro probe + sandboxed test suite)      ─▶ verified PR (@cirdan review loop; CI checks watched) ─▶ optional merge + deploy      ─▶ verify recovery in production

The job it does: when an alert fires at 3am for a code-shaped failure, a verified fix PR (or a completed deploy plus recovery confirmation) is waiting instead of a page.

Cirdan is deliberately not an infrastructure mapper, a topology explorer, an observability dashboard, a generic agent launcher, or a ChatOps bot. It repairs the services you register — nothing is discovered, and nothing is repaired implicitly.

Quickstart

pipx install "cirdanops[all]"      # or uv / pip / npm / brew / curl / docker — see Installcirdan setup                       # opens the local, loopback-only setup UI

cirdan setup walks one short path and shows a readiness banner that flips to "Ready to repair" only when this install can actually fix something:

1. Choose a pathway — Use the CLI (the tools already logged in on this machine) or Use the API (managed credentials + a GitHub App). See Two ways to run.
2. Connect an alert source — a Grafana webhook (+ HMAC), native Alertmanager intake, or Slack.
3. Select repair repositories — in Source Code Connection, Cirdan lists the repos your gh login can push to; pick which ones it may repair. Only selected repositories are ever repaired.
4. Prove routing — the Alert routing step synthesizes a sample alert (or takes a real payload you paste) and must show it resolving to a selected repository and routing to a code-repair pipeline.
5. Start the daemon and post a demo alert:

cirdand serve --httpcurl -X POST localhost:8090/v1/ingest/grafana -d @examples/demo/alert.firing.json

The runnable demo in examples/demo/ wires this end to end. The same checklist is available headlessly — cirdan status --checks prints the identical table and exits 1 until the install is ready. Useful setup flags:

• cirdan setup --terminal — the text step flow instead of the UI
• cirdan setup --all — run every step without prompting (scripts / CI)
• cirdan setup --system — machine-level scope in ~/.cirdan instead of a repo

Install

From PyPI (recommended):

uv tool install "cirdanops[all]"# orpipx install "cirdanops[all]"pip install "cirdanops[all]"

Without Python — npm / Homebrew / curl:

npx -y @cirdanops/cli serve-mcp        # run the MCP server, zero installnpm install -g @cirdanops/cli          # or put the `cirdan` command on your PATHbrew install adanb13/tap/cirdan        # macOS / Linux (Homebrew)curl -LsSf https://raw.githubusercontent.com/adanb13/cirdan/main/packaging/install.sh | sh# Windows: irm https://raw.githubusercontent.com/adanb13/cirdan/main/packaging/install.ps1 | iex

These ship a self-contained binary — no Python 3.11+ required. Supported: macOS (arm64), Linux x64/arm64 (glibc), Windows x64. On Intel Macs, Alpine/musl, or other platforms, use the PyPI install above.

Then set it up in one command (see Quickstart):

cirdan setup              # inside a repo# or, machine-level scope in ~/.cirdan:cirdan setup --system

Both open the same guided setup: choose a pathway, connect an alert source + GitHub, select repair repositories, prove routing, and start the always-on daemon.

Targeted installs: cirdanops[mcp], cirdanops[api], cirdanops[slack], cirdanops[agent], cirdanops[github-app], cirdanops[secrets], or combinations like cirdanops[api,mcp]. The sandbox runners need no extras — they use the docker/kubectl CLIs already on your PATH.

Prerequisites by platform (Python 3.11+ and uv or pipx):

# macOSbrew install [email protected] uv
# Windowswinget install astral-sh.uv
# Ubuntu / Debiansudo apt install python3.12 python3-pip pipx# or get uv:curl -LsSf https://astral.sh/uv/install.sh | sh

Docker (no Python needed):

# run the always-on repair daemon: alert receiver + isolated repair runner,# using the host's Docker for sandboxesdocker run -d \  -v "$PWD":/workspace:ro \  -v /var/run/docker.sock:/var/run/docker.sock \  -p 127.0.0.1:8090:8090 \  ghcr.io/adanb13/cirdan

(or docker compose up with the provided docker-compose.yml)

From source (latest unreleased):

pip install "cirdanops[all] @ git+https://github.com/adanb13/cirdan.git"

Two commands are installed:

Local development (from a clone)

Contributors work from a clone with an editable virtualenv, so changes to the working tree take effect immediately — no reinstall between edits. make install creates .venv and installs the package (distribution name cirdanops) editable with the [all,dev] extras — every runtime feature plus the test toolchain:

git clone https://github.com/adanb13/cirdan.gitcd cirdanmake install     # ≈ python3 -m venv .venv && .venv/bin/pip install -e ".[all,dev]"make test        # .venv/bin/python -m pytest tests/ -q

Requires Python 3.11+. The manual two-line equivalent works on a standard Python; make install additionally handles the pip-less-venv case (it falls back to python3 -m venv --without-pip and bootstraps pip into the venv).

The editable install puts both console scripts in .venv/bin, running working-tree code with no rebuild:

.venv/bin/cirdan setup                                    # or: .venv/bin/python -m cirdan.cli.main setup.venv/bin/cirdand serve --http.venv/bin/python -m pytest tests/test_slack_events.py -q  # a single test module

Common Make targets (make help lists them all):

On a headless box with no OS keyring, storing credentials during cirdan setup needs a master key in the environment first: export CIRDAN_MASTER_KEY=$(.venv/bin/python -c 'import os,base64;print(base64.b64encode(os.urandom(32)).decode())').

Two ways to run: Use the CLI / Use the API

The first setup screen picks a deployment posture (deployment_mode: in cirdan.yaml), which gates everything after it:

Use the CLI (cli, the default) — Cirdan runs with the tools already logged in on this machine. GitHub writes go through your gh auth login; the coding agent is a detected, logged-in Claude Code or Codex CLI, spawned headless inside the isolated repair workspace; the sandbox runner is your local Docker (or kubectl). The happy path needs no stored keys and no GitHub App — an env-var API key and a GitHub App remain available behind explicitly labeled "Advanced" toggles.

Use the API (api) — headless and managed, for shared/enterprise deployments. Provider API keys are stored encrypted (cirdan secret; AES-256-GCM), GitHub writes go through a GitHub App (guided manifest onboarding) with short-lived per-repo installation tokens, and the enterprise security profile is derived automatically: inherited gh auth and host-spawned CLI agents are refused at config load.

Both pathways end at the same readiness contract — the setup UI banner and cirdan status --checks render the same table: repair repositories selected (each with a resolvable repo) · an alert source connected · a routing proof (a sample or live alert demonstrably resolved to a selected repository and routed to a code pipeline) · remediation.mode ∈ {develop, deliver} · a live-probed coding agent · a verified GitHub write path including access to each selected repo · git on PATH · a working sandbox runner · the daemon running. Every red row shows the exact fix command or the setup step that resolves it.

Legacy configs load forever: deployment_mode: single-user reads as cli, business as api, and the file text migrates on the next setup save.

Configuration

cirdan setup writes cirdan.yaml for you; everything is also hand-editable — see cirdan.yaml.example. The heart of the file is the services: registry: the explicit list of services Cirdan may repair, how alerts resolve to them, and where their code lives.

services:  - name: checkout-api                 # canonical id (lowercase, node-id-safe)    repo: acme/checkout                # "org/name" — the PR / repair target    aliases: [checkout, checkout-svc]  # extra alert-label names for this service    match_labels: {team: payments}     # optional exact label matchers (first match wins)    deploy:                            # how it runs in prod + how the runner rebuilds it      kind: compose                    # compose | k8s | helm      compose_service: checkout-api    # defaults to the entry name      compose_files: [docker-compose.yml]    deploy_workflow: deploy.yml        # per-service GitHub Actions deploy (optional)    telemetry_service: checkout        # Loki/PromQL service label; defaults to name
  - name: payments-api    repo: acme/payments    source_root: ~/src/payments        # local checkout (cli pathway only)    deploy:      kind: k8s      namespace: prod      workload: payments-api           # kubernetes_kind defaults to Deployment

Alerts resolve to a service by an explicit cirdan_node label, then match_labels, then a ladder of common labels (service, service_name, app, job, deployment, statefulset, pod, container, the host of instance, annotations.service, alertname) matched against names + aliases. There is no implicit default: an alert that matches nothing opens a triage incident and never auto-repairs "the only registered repo".

Routing policy. Every alert source flows through one first-match-wins policy:

routing_policy:  rules:    - when: {service: checkout-api, severity: [high, critical]}      pipeline: full_remediation       # may merge/deploy — only under mode: deliver + the auto_* gates    - when: {source: slack}      pipeline: triage_only

With no matching rule, an alert that resolves to a registered service with a resolvable repo defaults to reproduce_and_pr_only at qualifying severity (responder.severities, default high/critical); everything else fails safe to triage_only. Pipelines, by decreasing depth: full_remediation · reproduce_and_pr_only · lightweight_pr_only · triage_only.

Safety gates (under source_hosts.github and remediation):

A failed deploy or failed production verification stops the delivery at manual_required, with the failure evidence notified and audited — Cirdan stops at manual intervention (automatic rollback is deliberately deferred).

Always ON

cirdand serve                        # ingest alerts, detect incidents, repair, deliver — forevercirdand serve --http                 # + the HTTP API (alert ingestion endpoints)cirdand serve --http --mcp           # + MCP mounted at /mcp

The daemon runs supervised loops — access refresh, alert ingestion + incident detection, delivery, PR-checks watching, @cirdan comment handling, and the Slack inbox (plus the Socket Mode client and webhook wakers, as configured). A crashing loop logs and restarts; it never takes the daemon down.

One instance per scope: a second cirdand serve (or cirdan watch) against the same scope is refused with the running pid. cirdan status / cirdan stop (also available on cirdand) inspect and shut it down.

Agent integration

Cirdan is also a tool surface for your coding agents: the same engine behind the CLI is exposed over MCP with exactly six read/evidence tools — list_incidents, explain_incident, get_recent_errors, get_logs, get_state, and get_audit. get_logs and get_state take a registered service name (or alias) from services: and resolve the live container/pod themselves. Everything returned is redacted.

cirdan install --project is a guided setup that leaves Cirdan running the repair loop, not just documented:

1. detects the agents on your machine (claude/codex/cursor/gemini/vscode/windsurf/opencode/goose config or CLIs) and writes instruction files for exactly those (plus generic AGENTS.md)
2. registers the MCP server in .mcp.json
3. arms the incident responder so daemon alerts route to your agent
4. starts the always-on daemon (detached; cirdand status / cirdand stop)

Steps 3–4 are prompted (default yes) or driven by flags for scripts: --responder/--no-responder, --daemon/--no-daemon, --all-platforms. Re-run any of it later with cirdan setup, which shows each step's current state and only proposes what's missing. Installs are idempotent and never touch content outside Cirdan's own marker block.

Supported agents. First-class auto-registration (native instruction file + MCP where the agent supports a writable config) covers Claude Code, Codex, Cursor, Gemini, VS Code (+ GitHub Copilot), Windsurf, Roo Code, Cline, opencode, and Goose. Any other agent works through the generic AGENTS.md + .agents/skills/cirdan/SKILL.md. Auto-detection finds claude/codex/cursor/gemini/vscode/windsurf/opencode/goose; pass --platform roo or --platform cline explicitly (they're VS Code extensions with no CLI to detect, and Cline keeps MCP config in editor storage, so add that one through its UI).

For any MCP client not listed, register Cirdan by hand — no Python required:

// npx form — zero install{ "command": "npx", "args": ["-y", "@cirdanops/cli", "serve-mcp"] }// or, if `cirdan` is already on PATH (pip / npm -g / brew / curl install):{ "command": "cirdan", "args": ["serve-mcp"] }

HTTP API

With the [api] extra, cirdand serve --http exposes /health, /incidents, /incidents/{id}, /incidents/{id}/explain, /audit, the alert intake under /v1/ingest/{grafana|alertmanager|…} (plus /v1/ingest/slack/events and a signature-verified /v1/ingest/github webhook waker), /v1/slack/interactions, a minimal OTLP/HTTP JSON receiver at /v1/logs, and the setup UI + API under /setup. Add --mcp to mount the MCP server at /mcp. State-changing routes are guarded — see SECURITY.md.

Upgrading

Nothing happens automatically — PyPI is pull-only, so an installed version keeps working as-is until you upgrade. New installs always get the latest release. Upgrading is one command, matching however you installed:

Two operational notes: existing cirdan-out/ artifacts and the SQLite store are compatible across releases so far (a schema-version key + migration will land before 1.0). And the CLI prints a single dim line on stderr when a newer release exists (checked at most once a day, interactive terminals only) — silence it with CIRDAN_NO_UPDATE_CHECK=1.

Upgrading from the mapping releases (≤ 0.9)

Cirdan committed to a single product: the repair workflow. The infrastructure-mapping surface — the graph/exploration commands, runtime profiles, and their artifacts — was removed. Removed commands and what replaces them:

Old configs keep loading: adapters:, enrich:, and profile: keys are accepted and ignored (profile warns once — Cirdan always runs the repair workflow), and deployment_mode: single-user/business normalize to cli/api. The [map] and [terraform] extras are gone from packaging. Old artifacts (infra.graph.json, INFRA_REPORT.md, infra.html, fingerprint.json, …) simply stop being written — Cirdan never deletes your files.

Security

Cirdan mirrors the access of the process it runs in and never escalates; everything it writes is redacted and audited. The two postures draw different trust boundaries: "Use the CLI" runs your own logged-in tools with your own permissions, while "Use the API" enforces the enterprise profile (GitHub App + stored keys, no host CLIs). Details — including network behavior and why PRs can only ever target the configured repo — in SECURITY.md.
