Introduction
ci-runner
Trigger your CI and get it fixed — a dsh plugin bundle that runs GitHub Actions workflows and local test pipelines, streams their logs back, tracks their status, and when something fails hands the tail of the log to DeepSeek for a Markdown root-cause report with fix steps.
- Two sources, one interface: GitHub Actions via
workflow_dispatch(+ check-run APIs) and local command pipelines (npm test,pytest, …) through the platform shell. - Bounded log reading: GitHub job logs streamed back per job and tail-truncated; local output captured with a per-stream cap so a runaway process can't blow up the agent context.
- DeepSeek diagnosis: on failure, the tail log plus a heuristic error
classification is sent to the harness
ctx.llm(or any configured OpenAI-compatible endpoint) to produce a report covering failure stage, error classification, most likely root cause, suggested fix steps and related files. - Status tracking: poll runs to completion (
queued/in_progress/completed) with configurable interval and a hard timeout. - Credentials by environment only: the GitHub token is read from an environment variable at call time, never logged and never persisted; every returned log and report is masked against known secrets.
- Zero runtime dependencies:
fetch+node:child_process, plain Node.js ESM, ships with five tools (ci_trigger,ci_status,ci_logs,ci_watch,ci_diagnose) and a matching CLI.
How it works
your repo / your machine
│ workflow_dispatch + check-run APIs shell (npm test, pytest, …)

│ trigger · status · logs · watch · diagnose
├─► dsh adapter: five ci_* tools on ctx.tools (ctx.llm for analysis)
├─► CLI: ci-runner trigger|status|logs|watch|diagnose
└─► report: Markdown with the five canonical sections
All state (stored local runs, config, secret-masking) lives in one
CiService instance, so tools and CLI behave identically. The dsh adapter
and the CLI are two thin entry points over it.
Requirements
- Node.js >= 18.17 (global
fetch) - For the dsh integration: a working DeepSeek Harness install providing the
toolsservice (and, for model-powered diagnosis, thellmservice). - A GitHub token in the environment (
GITHUB_TOKENby default) withactions:writescope for dispatch andactions:readfor status/logs.
Installation into dsh
As a dsh bundle (recommended)
A bundle is an npm package that contributes a configuration layer. From the profile you want to use:
dsh plugin --profile demo add ./path/to/ci-runner
This links the checkout and appends dsh-ci-runner to the profile's bundle
list because package.json declares dsh.bundle. Verify and boot:
dsh --profile demo --dump-config # shows the "# == dsh-ci-runner" layer
dsh --profile demo
The contributed patch layer (cordis.patch.yml) inserts one plugin row
mounting the adapter entry (a package subpath resolved through the package's
exports map):
- insert:
- id: ci-runner
name: dsh-ci-runner/adapter
As a patch overlay (no packaging)
Point the plugin row directly at the adapter source. Create an overlay file
ci-runner-patch.yml:
- insert:
- id: ci-runner
name: '<abs-path>/src/adapter.js'
and pass it to the harness:
dsh --patch ./ci-runner-patch.yml
Applying plugin config
When installed as a bundle, plugin configuration is set through the profile config (the layer contributed by the bundle) — every field is optional and defaulted:
# profile/config.yml
ci-runner:
github:
defaultRepo: acme/app
defaultBranch: main
diagnosis:
llm:
baseUrl: https://api.deepseek.com/v1
apiKey: sk-...
model: deepseek-chat
Without diagnosis.llm, analysis routes through the harness ctx.llm
service (preferred — matches the harness's configured provider). If neither
exists, diagnosis still produces a deterministic report (stage +
classification + log tail) with a note about the missing model.
Configuration
| Field | Default | Meaning |
|---|---|---|
github.tokenEnv | GITHUB_TOKEN | Env var holding the GitHub token (read at call time, never logged) |
github.defaultRepo | '' | Default owner/repo for GitHub calls |
github.defaultBranch | main | Ref used when a trigger doesn't specify one |
github.apiBase | https://api.github.com | REST base (GitHub Enterprise override) |
github.pollIntervalMs | 5000 | Poll interval for status tracking |
github.pollTimeoutMs | 600000 | Hard cap for waiting on a run |
github.dispatchWindowMs | 20000 | How long a dispatch may take to surface a run id |
github.requestTimeoutMs | 30000 | Per-request HTTP timeout |
github.readLogChars | 30000 | Default tail cap for ci_logs |
local.cwd | . | Working directory for command runs |
local.timeoutMs | 120000 | Hard timeout per command |
local.maxOutputChars | 40000 | Per-stream output cap |
local.templates | [{name: 'npm test', command: 'npm test'}, {name: 'pytest', command: 'pytest'}] | Named command templates |
diagnosis.llm | null | OpenAI-compatible endpoint override {baseUrl, apiKey, model} |
diagnosis.provider | '' | ctx.llm provider route ('' = auto) |
diagnosis.model | '' | ctx.llm model ('' = auto) |
diagnosis.maxTailChars | 12000 | Chars of the log tail sent to the model |
diagnosis.timeoutMs | 120000 | Hard budget for the analysis call |
diagnosis.temperature | 0.2 | Sampling temperature |
diagnosis.providerLabel | OpenAI-compatible | Label recorded in reports when the endpoint override is used |
Templates let the model and the CLI reference pipelines by name
(ci_trigger {source: local, command: 'npm test'}). Any value that doesn't
match a template name is treated as a raw shell command line.
Tools
| Tool | Purpose |
|---|---|
ci_trigger | Dispatch a GitHub workflow_dispatch (returns the run id) or run a local pipeline to completion |
ci_status | Single poll: status, conclusion, failed stage, jobs and steps |
ci_logs | Read logs, masked and tail-truncated; job selects one job |
ci_watch | (Optionally trigger and) wait until a run finishes; failed runs include the log tail |
ci_diagnose | End-to-end: run/wait, then send the failure tail to the analysis provider and return the Markdown report |
Report structure
ci_diagnose (and the CLI diagnose command) always emit the canonical
sections:
# CI Failure Report
## Failure Stage ← first failing job/step (or "Unknown")
## Error Classification ← heuristic rule-based pre-analysis
## Most Likely Root Cause ← model analysis (or a note when no model is available)
## Suggested Fix Steps ← model analysis
## Related Files ← model analysis (or "None identifiable from the log")
## Timeline ← start/end/duration when known
## Failure Log Tail ← masked, tail-truncated
When a model is available, its free-form Markdown is parsed back into these sections before rendering, so the structure is stable even as the model's wording varies.
CLI
ci-runner trigger [--source github|local] [--repo owner/repo] [--workflow F]
[--ref R] [--inputs k=v ...] [--command CMD] [--template T]
[--cwd DIR]
ci-runner status [--source s] --run ID [--repo r]
ci-runner logs [--source s] --run ID [--job J] [--tail N] [--repo r]
ci-runner watch [--source s] [--run ID | trigger flags] [--timeout-ms N]
[--interval-ms N] [--no-logs] [--json]
ci-runner diagnose [--source s] [--run ID | trigger flags] [--save PATH]
[--llm-base-url URL] [--llm-model M] [--llm-api-key K]
Global: --config PATH (JSON config file), --json, --help, --version.
For diagnose without a config file, pass --llm-base-url (+ --llm-model
and optionally --llm-api-key; keys can also come from CI_RUNNER_LLM_API_KEY
or OPENAI_API_KEY).
Local run ids are process-local:
status/logson a local run work with a run id captured inside the same invocation. Across CLI invocations, drive local pipelines withwatch/diagnose+--command(or use GitHub runs, whose state lives server-side). Inside dsh, all five tools share one process, so captured run ids stay valid for the plugin's lifetime.
Examples
# GitHub: dispatch ci.yml on main with inputs and print the run id
ci-runner trigger --workflow ci.yml --repo acme/app --ref main --inputs env=prod
# Local: run the "pytest" template (or any raw command)
ci-runner trigger --source local --template pytest --cwd ./api
# Wait for run 123456789, show the tail if it failed
ci-runner watch --run 123456789 --repo acme/app --timeout-ms 600000
# Local failure → DeepSeek diagnosis (markdown report, also saved to disk)
ci-runner diagnose --source local --command "npm test" \
--llm-base-url https://api.deepseek.com/v1 --llm-model deepseek-chat \
--save report.md
Security notes
- The GitHub token is read from
process.env[github.tokenEnv]on every call and exists only in memory; it is never written to logs, reports or disk. - All returned log text is masked against the GitHub token and any configured
analysis API key (
***substitution). - Local commands run in the configured
cwdonly and are killed as a process tree on timeout — no orphaned grandchildren keep running. - Diagnosis payloads contain the log tail only; the token never reaches the model.
