What is coding.fix_dasserts?

A Python code-cleanup skill that replaces generic assertion statements with more specific diagnostic checks. It also requires each check to include a clear message.

Use it on Python files containing generic assert calls or hdbg.dassert() calls that should use the appropriate hdbg.dassert_* function.

Generic assertions can make failures harder to understand. More specific checks can give clearer information when a test or validation fails.

Token cost

What it costs to keep this loaded

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 5.1	$0.00006	$0.00122
Opus 5.5	$0.00002	$0.00049
Sonnet 5.5	$0.00001	$0.00024
Haiku 4.5	$0.00001	$0.00012

Security

Grade A, and why

coding.fix_dasserts 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.

I will pass you one or more files <FILES>
Use the proper dasserts following instructions in .claude/skills/coding.rules.md in section
```
## Use Specialized `dassert_*`
```

Verification

Confirm generic assert and hdbg.dassert() calls are replaced with the most specific hdbg.dassert_* function
Confirm each dassert_* call has a clear message

Changes

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.
