github/temporary-id-safe-output
Add temporary ID support to safe-output jobs end to end.
npx skills add https://github.com/github/gh-aw --skill temporary-id-safe-output
Use this implementation plan for temporary ID support in safe output jobs. Temporary IDs let agents reference newly created issues in the same run before real issue numbers exist.
When an agent creates a parent issue and immediately links sub-issues in the same run, it does not know the real issue number until create_issue completes. Temporary IDs bridge this gap with placeholders resolved at execution time.
Temporary IDs follow the pattern aw_[A-Za-z0-9]{3,8} where:
aw_ is a fixed prefix identifying agentic workflow temporary IDsXXXXXXXX is a 3-8 character alphanumeric string (A-Za-z0-9)Example: aw_abc, aw_abc123, aw_Test123

This module provides shared utilities for temporary ID handling:
// Core functions
generateTemporaryId() // Generate new temporary ID
isTemporaryId(value) // Check if value is a temporary ID
normalizeTemporaryId(tempId) // Normalize to lowercase for map lookups
loadTemporaryIdMap() // Load map from GH_AW_TEMPORARY_ID_MAP env var
resolveIssueNumber(value, map) // Resolve value to issue number (supports temp IDs)
replaceTemporaryIdReferences(text, map) // Replace #aw_XXX references in text
create_issueThe create_issue job outputs a temporary ID map that other jobs can consume:

temporary_id -> issue_numbercore.setOutput("temporary_id_map", JSON.stringify(map))For each safe output job that needs to resolve temporary IDs:
In pkg/workflow/<job_name>.go:
createIssueJobName parameter to the build function:func (c *Compiler) build<JobName>Job(data *WorkflowData, mainJobName string, createIssueJobName string) (*Job, error) {
if createIssueJobName != "" {
customEnvVars = append(customEnvVars, fmt.Sprintf(" GH_AW_TEMPORARY_ID_MAP: ${{ needs.%s.outputs.temporary_id_map }}\n", createIssueJobName))
}
create_issue to the job's needs array:needs := []string{mainJobName}
if createIssueJobName != "" {
needs = append(needs, createIssueJobName)
}
SafeOutputJobConfig to use the dynamic needs:return c.buildSafeOutputJob(data, SafeOutputJobConfig{
// ...
Needs: needs,
// ...
})
In pkg/workflow/compiler_jobs.go:
Pass the createIssueJobName when building the job:
job, err := c.build<JobName>Job(data, mainJobName, createIssueJobName)
In pkg/workflow/js/<job_name>.cjs:
const { loadTemporaryIdMap, resolveIssueNumber } = require("./temporary_id.cjs");
const temporaryIdMap = loadTemporaryIdMap();
if (temporaryIdMap.size > 0) {
core.info(`Loaded temporary ID map with ${temporaryIdMap.size} entries`);
}
resolveIssueNumber() to resolve issue numbers:const resolved = resolveIssueNumber(item.issue_number, temporaryIdMap);
if (resolved.errorMessage) {
core.warning(`Failed to resolve issue: ${resolved.errorMessage}`);
continue;
}
const issueNumber = resolved.resolved;
if (resolved.wasTemporaryId) {
core.info(`Resolved temporary ID '${item.issue_number}' to issue #${issueNumber}`);
}
In pkg/workflow/js/collect_ndjson_output.cjs:
Add validation for fields that accept temporary IDs:
function isValidIssueNumberOrTemporaryId(value) {
if (typeof value === "number" && Number.isInteger(value) && value > 0) {
return true;
}
if (typeof value === "string" && /^aw_[0-9a-f]{12}$/i.test(value)) {
return true;
}
return false;
}
Use this validation for fields like parent_issue_number, sub_issue_number, etc.
When temporary ID resolution fails, the job should:
core.warning() instead of failing with core.setFailed()This ensures that:

The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
