CSPeach

AI-assisted ABAP development CLI. 34 skills, direct SAP access, safety gates the model cannot bypass.

Install

npm install -g @cspeach/cli

Requires Node.js 20+. After install:

cspeach login         # opens browser, authorizes this machine
cspeach config add-sap
cspeach               # interactive REPL

What it does

CSPeach runs an AI consultant against your own SAP. Pick a skill (or type a prompt — the classifier picks one for you):

/abap-spec-gap        find missing questions before any code is written
/abap-design          object list + dependency DAG
/abap-estimate        component-level hours with optimistic / realistic /
                      pessimistic ranges
/abap-cca             estate-wide custom-code analysis for S/4HANA
/abap-upgrade-scan    baseline scan against the readiness variant
/abap-upgrade-fix     interactive fix loop with per-object approval
/abap-incident        short dump → fix → verify → handover
cspeach --help        full skill list (34 total)

Every turn runs locally on your machine. SAP source and SAP data flow through api.cspeach.dev to the LLM. The proxy logs request metadata (skill, model, token counts, latency) for billing; the message body is forwarded to Anthropic and not stored on the proxy. SAP credentials never leave your machine.

Safety

• Snapshot gate — every SAP write auto-snapshots first
• SAP approval gate — SAP-write and transport tools (sap_set_source, sap_create_object, sap_delete_object, sap_update_method, sap_activate, sap_transport_*) require a single-use JWT bound to (object, operation); the model sees a plan, you approve each change
• Optional tools default OFF — filesystem, shell, web, and subagent tools are invisible to the model unless you set CSPEACH_TOOL_<NAME>=on in the environment
• Batch-write interrupt — any second mutating call in a single turn (Rule 8, any tool category) pauses for an explicit yes/no before it runs
• Verify gate — every SAP write is syntax-checked; activation blocked on errors
• Transport discipline — all SAP writes land in your session transport; $TMP is opt-in

Ten Forge Rules are non-negotiable. Full philosophy in the CSPeach Principles preamble shown to the model every turn.

Cost transparency (since 0.7.0)

Every turn shows what it cost. After each model call you see:

session abc123 │ S4H │ /abap-explain │ 2 turns │ 487 tok │ $0.07 │ session: $0.18 │ 3.6s

• tok = tokens billed this turn (input + output + cache)
• $ = this turn's cost
• session: = cumulative across the open session
• /cost shows a per-skill / per-tool breakdown
• /compact summarises older turns when context gets large (cuts subsequent-turn cost ~80-90%)
• auto_compact in ~/.cspeach/config.toml fires /compact automatically over a configurable threshold

On /exit you get a session summary + the cspeach --resume <id> command in plain text so you can pick up where you left off.

UI modes

Two REPL modes, both supported. Default is classic. Switch with /ui ink or /ui classic; saves to ~/.cspeach/config.toml under [ui].

• classic — chalk + readline. The supported, demo-tested mode. Use this unless you have a reason not to. Native terminal scroll, mouse wheel, search — everything your terminal does naturally just works.
• ink — React-based TUI. PREVIEW. Some rendering quirks remain (occasional phantom cursor, picker fossil in scrollback). Functional for daily use but not yet polished enough to recommend as default. Promoted to default in a later release.

If ink is misbehaving for you, run /ui classic once — change applies after relaunch.

Configuration

~/.cspeach/config.toml is created on first cspeach config add-sap:

proxy_url     = "https://api.cspeach.dev"
default_model = "claude-opus-4-7"

[sap.S4H-DEV]
host     = "sap-dev.company.com"
port     = 44300
client   = "100"
useSsl   = true
username = "S.LAEEQ"

SAP passwords are stored in your OS keychain.

Common commands

cspeach login                    sign in to api.cspeach.dev
cspeach whoami                   show signed-in identity + plan/trial
cspeach logout                   clear local auth
cspeach config add-sap           add a SAP system
cspeach doctor                   diagnose install + connectivity
cspeach --resume                 resume a prior session
cspeach --upgrade                pull the latest CLI release
cspeach --version

Troubleshooting

If cspeach doctor fails:

• auth — run cspeach login again
• keychain — Windows Credential Manager / libsecret missing; CSPeach falls back to per-session prompts, slower but functional
• sap — host unreachable; check VPN + the host/port in config

If the REPL hangs on first prompt, check https://api.cspeach.dev/health.
