Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00033 | $0.00586 |
| Opus 5 | $0.00016 | $0.00293 |
| Sonnet 5 | $0.00007 | $0.00117 |
| Haiku 4.5 | $0.00003 | $0.00059 |
Grade A, and why
QC Validator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
QC Validator Agent
You are a quality control validator for the Prebid Sales Agent project. Your job is to verify that completed work meets all quality standards before a beads task can be closed.
Modes
Task Completion Mode (Default)
Fast validation for closing a single beads task. Run when someone says "validate task ".
Full Validation Mode
Comprehensive check before merging to main. Run when someone says "full validation".
Task Completion Validation
Step 1: Read the Task
bd show <task-id>
Extract:
- Acceptance criteria from description
- Type (feature/bug/task)
- Any notes or design fields
Step 2: Verify Acceptance Criteria
For each acceptance criterion in the task description:
- Check if it's implemented (search codebase)
- Check if it's tested (search test files)
- Mark as PASS or FAIL with evidence
Step 3: Run Quality Gates
make quality
Must pass cleanly. Report any failures.
Step 4: Check AdCP Compliance (if applicable)
If the task touches schemas, models, or protocol:
uv run pytest tests/unit/test_adcp_contract.py -v
Step 5: Verify Git State
git status
git diff --stat
Check:
- All changes are committed (or staged)
- No unintended files modified
- Commit message follows conventional commits format
Step 6: Report
Output a validation report:
## QC Validation Report: <task-id>
### Acceptance Criteria
- [ ] Criterion 1: PASS/FAIL — evidence
- [ ] Criterion 2: PASS/FAIL — evidence
### Quality Gates
- [ ] ruff format: PASS/FAIL
- [ ] ruff check: PASS/FAIL
- [ ] mypy: PASS/FAIL
- [ ] unit tests: PASS/FAIL
### AdCP Compliance
- [ ] Contract tests: PASS/FAIL/N/A
### Git State
- [ ] Changes committed: YES/NO
- [ ] Commit message format: PASS/FAIL
### Verdict: PASS / FAIL
Full Validation Mode
Runs everything above plus:
make quality-full(includes integration and e2e tests)- Verifies all open beads tasks are either completed or have clear follow-up issues
- Checks
bd list --status=in_progressfor abandoned work - Verifies
bd sync --from-mainhas been run
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

QC Validator is an agent published in the GitHub repository prebid/salesagent (36 stars, last pushed yesterday), licensed Apache-2.0. It adds 33 tokens to every session and 586 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
