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 | $0.00053 | $0.02447 |
| Opus 5 | $0.00026 | $0.01223 |
| Sonnet 5 | $0.00011 | $0.00489 |
| Haiku 4.5 | $0.00005 | $0.00245 |
Grade A, and why
python-canary-fix 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 2d ago.
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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Python Canary Fix
Investigate failures in the Python canary cron (python-cron.yaml) workflow and propose a fix for Python instrumentation packages.
When to Use
- User mentions Python canary cron failures
- A scheduled trigger reports canary failures
- User asks to investigate
*-latesttest environment failures - Invoked automatically by the
auto-fixjob inpython-cron.yaml
Workflow
Each failing package is investigated and fixed independently, with its own branch and its own PR. Do not bundle fixes for multiple packages together, even when they share an apparent root cause — keep PRs scoped to a single instrumentor so they can be reviewed, reverted, and released independently.
When invoked by the scheduled auto-fix job, the workflow already runs one job per failing package and creates the branch before Claude starts. In that mode, follow the prompt's package scope, do not commit, push, or open a PR, and instead write:
.scratch/pr-title.txt: a one-line conventional-commit PR title..scratch/pr-body.md: a concise PR body with root cause, fix, and commands run.
The workflow will commit, push, and open the PR after Claude exits. It does not re-validate your fix in-workflow — the opened PR's own CI runs this package's -latest envs and is the gate (branch protection blocks merging until CI is green), so still aim to make the failing env pass, but an imperfect fix becomes a red PR for a human to finish rather than being discarded. The workflow also skips invoking you entirely when an open auto-fix PR for the package already exists, so you do not need to guard against that case. For manual use outside CI, continue to open one PR per package yourself.
In CI auto-fix mode, the workflow downloads the failed tox logs before Claude starts. Always read .scratch/failure-logs/*.log first and use the first traceback or assertion from those local logs as the primary signal. Do not call gh run view --log or gh run view --log-failed for the same in-progress run unless the local logs are missing or clearly incomplete.
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.

python-canary-fix is a skill published in the GitHub repository Arize-ai/openinference (1,186 stars, last pushed 2d ago), licensed Apache-2.0. It adds 53 tokens to every session and 2,447 once invoked, about $0.0003 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 2026-08-30.
