Fix copilot fallback model path to use COPILOT_MODEL env var instead of --model flag by Copilot · Pull Request #19509 · github/gh-aw

Copilot · 2026-03-04T05:08:48Z

When engine.model is not set in frontmatter, the compiler was appending ${GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"} to the shell command. The Copilot CLI rejects --model as a flag entirely — only COPILOT_MODEL env var is supported. This made the org-variable model path broken for every workflow not using inline engine.model.

Changes

`copilot_engine_execution.go`

Removed needsModelFlag and the ${VAR:+ --model "$VAR"} shell expansion entirely
Fallback path now maps the org variable into COPILOT_MODEL directly, matching the explicit-model path:

# Before (broken)
run: copilot ... ${GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"}
env:
  GH_AW_MODEL_AGENT_COPILOT: ${{ vars.GH_AW_MODEL_AGENT_COPILOT || '' }}

# After (correct)
run: copilot ...
env:
  COPILOT_MODEL: ${{ vars.GH_AW_MODEL_AGENT_COPILOT || '' }}

Applies to both agent (GH_AW_MODEL_AGENT_COPILOT) and detection (GH_AW_MODEL_DETECTION_COPILOT) jobs.

`model_env_vars_test.go`

Removed copilot cases from TestModelEnvVarInjectionForAgentJob and TestModelEnvVarInjectionForDetectionJob — they were asserting the broken --model flag behavior
Added TestCopilotFallbackModelMapsToNativeEnvVar covering both agent and detection job variants

`heredoc_interpolation_test.go`

Fixed a test that was checking for ${GH_AW_ in compiled output — this was only passing because the now-removed model flag expansion happened to match. The prompt content actually uses __GH_AW_...__ (Handlebars placeholder syntax); updated check accordingly.

Golden files & lock files

Updated wasm golden files and recompiled all 165 workflow lock files to reflect the new env block structure.

Original prompt

This section details on the original issue you should resolve

<issue_title>Copilot engine fallback model path uses --model CLI flag instead of COPILOT_MODEL env var</issue_title>
<issue_description>## What happens

When engine.model is not explicitly configured in workflow frontmatter, the compiler generates a shell command that conditionally appends --model "$GH_AW_MODEL_AGENT_COPILOT" as a CLI flag to the Copilot CLI invocation. The Copilot CLI does not accept --model as a flag — it errors with argument '<model>' is invalid.

When engine.model is configured, the compiler correctly sets the COPILOT_MODEL environment variable, which the Copilot CLI reads natively. So the "explicit model" path works, but the "fallback from GitHub org variable" path is broken.

The test suite contains contradictory expectations: one test expects the --model flag to appear, while another asserts it should NOT appear.

What should happen

Both code paths should use COPILOT_MODEL as an environment variable. When the model comes from a GitHub org variable (GH_AW_MODEL_AGENT_COPILOT), the compiler should map it to COPILOT_MODEL in the step's env: block rather than appending it as a CLI flag.

Where in the code

All references are to main at 99b2107.

Path selection:

copilot_engine_execution.go:78 — modelConfigured := workflowData.EngineConfig != nil && workflowData.EngineConfig.Model != "" determines which path is taken

Broken fallback path (no explicit model):

copilot_engine_execution.go:154 — needsModelFlag := !modelConfigured
copilot_engine_execution.go:182-183 — sandbox mode: generates ${GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"}
copilot_engine_execution.go:191-192 — non-sandbox mode: same --model flag expansion
copilot_engine_execution.go:312-318 — sets GH_AW_MODEL_AGENT_COPILOT or GH_AW_MODEL_DETECTION_COPILOT in env block (the value source is correct, but it's consumed as a CLI flag)

Correct explicit-model path:

copilot_engine_execution.go:309-311 — env[constants.CopilotCLIModelEnvVar] = workflowData.EngineConfig.Model — sets COPILOT_MODEL directly

Contradictory tests:

model_env_vars_test.go:21-25 — expects --model flag in shell command (tests the broken behavior)
model_env_vars_test.go:213-243 — asserts --model flag should NOT appear when COPILOT_MODEL env var is used

Evidence

Source-level verification (2026-03-03):

Confirmed both code paths exist at the specified lines on current main
Confirmed needsModelFlag is true exactly when modelConfigured is false
The generated shell expansion ${GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"} will pass --model gpt-5 (or whatever value) as a positional argument to the Copilot CLI

Copilot CLI verification (v0.0.421):

copilot --model gpt-5 --prompt 'say hi' fails with argument 'gpt-5' is invalid
COPILOT_MODEL=gpt-5 copilot --prompt 'say hi' runs normally
Confirms the CLI does not accept --model as a flag; the env var is the only supported mechanism

Related issue: #17265 (closed) requested the model be provided via env var. The fix was applied for the explicit-model path (COPILOT_MODEL env var) but the fallback path was missed and still uses the broken --model flag.

Proposed fix

In copilot_engine_execution.go, when needsModelFlag is true, instead of generating ${GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"} in the shell command, map the org variable to COPILOT_MODEL in the step's env: block:

// Instead of appending --model to the shell command,
// map the org variable to the native env var:
env[constants.CopilotCLIModelEnvVar] = fmt.Sprintf("${{ vars.%s || '' }}", constants.EnvVarModelAgentCopilot)

Remove the needsModelFlag / --model flag expansion from buildCopilotCommand() entirely. Update the contradictory test at model_env_vars_test.go:21-25 to expect COPILOT_MODEL in the env block instead of --model in the command string.

Impact

Frequency: Affects every workflow run where the model is configured via GitHub org variables (GH_AW_MODEL_AGENT_COPILOT / GH_AW_MODEL_DETECTION_COPILOT) rather than inline engine.model frontmatter. This is the default path for repos that don't customize per-workflow.
Cost: The --model flag produces a hard error from the Copilot CLI. If the org variable is set, the run fails immediately. If the org variable is unset, the conditional expansion is a no-op and the default model is used — so the bug is latent until someone configures the org variable.</issue_description>

Hey @pelikhan 👋 — great to see this bug fix being tracked! Issue #19473 was a well-analyzed agentic plan from the community, and this PR is the right vehicle to address it.

This is a WIP draft with no code committed yet — all tasks in the checklist are still pending. Here's a summary of what remains to land this fix:

Remove needsModelFlag / --model shell expansion — pkg/workflow/copilot_engine_execution.go lines 154, 182–183, and 191–192 still generate \$\{GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"}, which the Copilot CLI rejects with argument '' is invalid.
Fix the env-block fallback — lines 312–318: instead of setting GH_AW_MODEL_AGENT_COPILOT / GH_AW_MODEL_DETECTION_COPILOT (consumed as a CLI flag), map the org variable to COPILOT_MODEL (constants.CopilotCLIModelEnvVar) directly in the env: block.
Update TestModelEnvVarInjectionForAgentJob — the Copilot test case at model_env_vars_test.go:21–25 currently expects the broken --model flag behavior. It needs to be updated or removed.
Add TestCopilotFallbackModelMapsToNativeEnvVar — a new test asserting COPILOT_MODEL appears in the env block (not as a CLI flag) when the model comes from the GH_AW_MODEL_AGENT_COPILOT org variable.

…model CLI flag When engine.model is not configured, the compiler was generating ${GH_AW_MODEL_AGENT_COPILOT:+ --model "$GH_AW_MODEL_AGENT_COPILOT"} in the shell command. The Copilot CLI does not accept --model as a flag. Now both the explicit and fallback paths use COPILOT_MODEL env var: - Explicit: COPILOT_MODEL: <configured-value> - Fallback: COPILOT_MODEL: ${{ vars.GH_AW_MODEL_AGENT_COPILOT || '' }} Also fixes TestHeredocInterpolation to check for __GH_AW__ placeholder syntax instead of ${GH_AW_} shell syntax in prompt content.

Copilot

Pull request overview

Fixes Copilot engine’s “fallback model” behavior by removing the invalid --model CLI flag usage and instead mapping the org-level model variables (GH_AW_MODEL_*_COPILOT) into the native COPILOT_MODEL environment variable, aligning fallback behavior with the explicit engine.model path.

Changes:

Updated Copilot engine execution step generation to always pass the model via COPILOT_MODEL (no --model flag / shell expansion).
Updated/added tests to assert the new fallback mapping behavior and adjusted a heredoc interpolation assertion to match the actual placeholder syntax.
Regenerated wasm golden outputs and updated numerous workflow lock files to reflect the new env: layout.
