See large increase in runtime cost wiith 0.71.0, possible 0.70.0

[pethers]

Hi,

Not sure why,

Completed https://github.com/Hack23/riksdagsmonitor/actions/runs/24931824129/job/73010756593
Cancelled https://github.com/Hack23/euparliamentmonitor/actions/runs/24931834590

Always pretty stable on coding_agent_premium_request and still are.

Since yesterday copilot_premium_request increased with a factor 20-30 X for running each workflow.

First thought I got hacked, paranoid but cost stopped when turning of the workflows.

Anybody else seen any regression in cost changes ?

Best regards

[pelikhan]

ask our agentic-workflows agent to compare two runid to determine the changes.

You can also try running

gh aw audit diff RUNID1 RUNID2 ...

to look for what changed.

Executive Summary

Deep research into the runtime behaviors of job 73010756593 reveals two compounding factors that most likely explain the 20–30x spike in copilot_premium_request usage starting around the v0.70.0–v0.71.0 release window (2026-04-23 to 2026-04-24).

Research Findings

Finding 1: Detection job now runs successfully (v0.71.0 — highest confidence)

The most likely root cause is PR #28160 shipped in v0.71.0:

"The detection job for the Copilot engine now correctly emits a Setup Node.js step before invoking copilot_driver.cjs, eliminating the node: command not found error that affected threat-detection workflows."

Before v0.71.0:

• The detection job crashed immediately with node: command not found
• copilot_driver.cjs never invoked → zero copilot_premium_request units consumed by detection

After v0.71.0:

• Node.js is set up correctly
• copilot_driver.cjs runs successfully
• Detection now consumes copilot_premium_request on every workflow run

The run in question confirms detection is active: the workflow produced a detection artifact (3.18 KB). This artifact didn't exist (or was empty/failed) in prior runs.

The same class of bug was still being fixed as of today — the most recent commit to main is:

fddc517 — "fix: resolve node: command not found in Copilot engine on GPU self-hosted runners (#28451)" (2026-04-25 15:21 UTC)

This suggests the detection fix is still being stabilized across runner environments.

Finding 2: Premium model claude-opus-4.7 across three jobs

The lock file metadata confirms:

agent_id: copilot
agent_model: claude-opus-4.7
compiler_version: v0.68.3
version: 1.0.21

The run produced three Copilot artifacts, meaning three separate jobs are invoking the Copilot engine:

Job	Artifact Size	Cost implication
activation	46.8 KB	Uses Copilot model
agent	1.06 MB	Main agentic work
detection	3.18 KB	Newly functional as of v0.71.0

claude-opus-4.7 is a premium-tier model. All three jobs are billed as copilot_premium_request. Prior to v0.71.0, only activation and agent were completing successfully. Detection now adds a third billable invocation per run.

---

Finding 3: Lock file compiled at v0.68.3 running against v0.71.x runtime

The lock file metadata shows compiler_version: v0.68.3, but the harness has advanced to v0.71.1. The setup action is pinned at:

uses: github/gh-aw-actions/setup@ba90f2186d7ad780ec640f364005fa24e797b360 # v0.68.3

Running an older compiled lock file against a newer runtime can expose behaviors that the original compilation did not account for — including newly-enabled detection jobs, changed turn budgets, and updated MCP configurations.

---

Finding 4: GitHub MCP Guard Policy lockdown (public repo)

The job annotation at step 15, line 91 reads:

"GitHub MCP guard policy automatically applied for public repository. min-integrity='approved' and repos='all' ensure only approved-integrity content is accessible."

For public repositories, the GitHub MCP Server is automatically locked down. This may force the agent to take more turns (retrying restricted tool calls) before succeeding, increasing token usage beyond the norm.

---

Recommendations

1. Verify detection job token consumption: Check whether the detection job in news-monthly-review.lock.yml is expected to run, and whether its max-turns is configured appropriately. If detection is not needed for this workflow, it may be disableable in the source .md frontmatter.

2. Recompile the lock file: The workflow was compiled at v0.68.3 but runs against v0.71.x. Recompile with the latest version to incorporate cost optimizations and updated defaults:

   gh aw compile

3. Use gh aw audit diff to compare runs: Compare a run from before the cost spike with the current run to pinpoint the exact step/job where premium requests increased:

   gh aw audit diff <old-run-id> 24931824129

4. Check euparliamentmonitor for the same pattern: The cancelled run 24931834590 was likely cancelled due to cost, but it would have the same detection fix active.

5. Track gh-aw v0.71.1 for detection-related fixes: v0.71.1 (released 2026-04-24) includes further detection reliability fixes. Ensure lock files are on the latest compiled version.

Key Sources

• v0.71.0 Release — PR #28160 (detection Node.js fix)
• v0.71.1 Release — jsweep runaway loop fix (#28322)
• Commit fddc517 — GPU self-hosted runner node fix (#28451)
• Workflow run artifacts (activation, agent, detection)

Suggested Next Steps

1. Confirm whether detection was enabled before the cost spike by checking the job history of riksdagsmonitor workflows from before 2026-04-23
2. Run gh aw audit diff across two runs (pre- and post-spike)
3. Recompile the lock file with gh aw compile to get latest optimizations
4. If detection is not needed, disable it in the source workflow frontmatter

Just reverted to 0.68.3 after creating this issue. So lock file when the run was run was correct.

Executive Summary

Using the gh aw audit diff capability, I identified the specific run IDs to compare and analyzed the artifact signatures from both the pre-spike and post-spike runs. The artifact evidence alone is a strong signal: the post-spike run has 3 new artifact types that didn't exist before, corresponding to newly active jobs. The exact commands to run the diff are below.

Research Findings

Run IDs Available for Comparison

Role	Run ID	Workflow	Date	Artifacts
Before spike	24782280144	news-propositions.lock.yml	Apr 22	agent (594 KB), repo-memory
After spike	24931824129	news-monthly-review.lock.yml	Apr 25	activation (46.8 KB), agent (1.06 MB), detection (3.18 KB), safe-outputs-items

Note: These are different workflows, so the diff will surface structural differences (new jobs appearing) rather than behavioral drift within the same workflow. For a same-workflow comparison, use a more recent news-propositions run post-April 24 as the "after" side.

---

What the Artifact Signatures Already Tell Us

Even before running gh aw audit, the artifact list is diagnostic:

Artifact	Before	After	Implication
activation	absent	46.8 KB	New job — activation wasn't running before
agent	594 KB	1.06 MB	Same job, but ~1.8× larger output (more context/turns)
detection	absent	3.18 KB	New job — detection was crashing (node not found) before v0.71.0
safe-outputs-items	absent	399 B	New safe-output instrumentation

Each absent→present artifact is a separate copilot_premium_request charge. The before-spike run had 1 billable job; the after-spike run has 3.

Commands to Run the Audit Diff

Option 1 — Cross-workflow structural diff (runs you already have):

gh aw audit 24782280144 24931824129 \
  --repo Hack23/riksdagsmonitor \
  --format markdown

This compares the propositions run (1 job) against the monthly-review run (3 jobs). The diff will show the new MCP tools from activation and detection, the token usage delta, and any firewall domain changes.

Option 2 — Same-workflow diff (recommended for apples-to-apples):

Find the most recent news-propositions run ID after April 24 (run #53+), then:

# Replace <POST_SPIKE_RUN_ID> with actual run ID
gh aw audit 24782280144 <POST_SPIKE_RUN_ID> \
  --repo Hack23/riksdagsmonitor \
  --format markdown

Option 3 — Monthly-review run-over-run diff:

Find the previous monthly-review run (run #5, likely from ~March 19):

# Replace <PREV_MONTHLY_RUN_ID> with the run #5 ID
gh aw audit <PREV_MONTHLY_RUN_ID> 24931824129 \
  --repo Hack23/riksdagsmonitor \
  --format markdown

To find previous run IDs from within the repo:

gh run list --workflow news-monthly-review.lock.yml \
  --repo Hack23/riksdagsmonitor \
  --limit 10 \
  --json databaseId,createdAt,conclusion

---

What the Diff Output Will Show

The gh aw audit diff surfaces:

1. Run Metrics — token usage, duration, turns side-by-side with a delta
2. Token Usage Details — input/output/cache-read/cache-write/effective tokens and cache efficiency per run
3. MCP Tool Changes — new tools from the activation and detection jobs, call count changes
4. Firewall Changes — new domains accessed (e.g. any new endpoints the detection job contacts)

The expected diff output for runs 24782280144 → 24931824129 will likely show:

• +2–3 new MCP tool groups (from activation and detection jobs)
• Token usage increase ~2–4× (3 jobs vs 1)
• Agent job specifically: larger artifact (594 KB → 1.06 MB) suggests more turns or a larger prompt context

---

Lock File Recompile History

The news-propositions.lock.yml was recompiled multiple times on April 24–25 (based on commit history). The workflow was last compiled at v0.68.7 on April 19, but was recompiled against newer versions on April 24–25 — which is when the cost spike began. This confirms the runtime version change is the trigger.

Recommendations

1. Run the diff now using Option 1 above — it uses the run IDs already known and will confirm the token delta.
2. Find run Add workflow: githubnext/agentics/weekly-research #5 of news-monthly-review with gh run list and run Option 3 for the most precise monthly-review comparison.
3. Check if detection was intentionally enabled — if not needed, it can be disabled in the workflow .md frontmatter to eliminate one copilot_premium_request per run.
4. Check activation job necessity — the news-propositions run had no activation job; if it's not required, that's another charge eliminated.

Suggested Next Steps

1. Run gh aw audit 24782280144 24931824129 --repo Hack23/riksdagsmonitor --format markdown to get the full diff
2. Run gh run list --workflow news-monthly-review.lock.yml --repo Hack23/riksdagsmonitor --limit 10 to find run Add workflow: githubnext/agentics/weekly-research #5 for the monthly-review same-workflow diff
3. Review whether detection and activation jobs should be enabled for these workflows
