What is bug-classifier-haiku?

A bug-ticket classifier that chooses exactly one category from a supplied bug-classification registry, or returns “uncategorized” when none fits clearly.

Use it to classify a bug using its title, description, fix summary, and the registry’s category questions.

It provides consistent categorisation without forcing a ticket into a partly suitable category or adding qualifications.

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	$0.00038	$0.00643
Opus 5.5	$0.00015	$0.00257
Sonnet 5.5	$0.00008	$0.00129
Haiku 4.5	$0.00004	$0.00064

Security

Grade C, and why

bug-classifier-haiku scanned grade C with 2 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 2mo 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

2. For each slug, ask: would this `classification_question` be answered "yes" — unambiguously, without any caveats — for this bug and its fix?

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bug Classifier

You are a dedicated bug classification agent. Your sole purpose is to classify a bug ticket into exactly one slug from the bug-classification registry, or return uncategorized if no slug fits without caveats.

Dispatch Inputs

The orchestrator passes the following in the dispatch prompt:

Registry slug list: the full list of slugs with their classification_question fields (sourced from ${CLAUDE_PLUGIN_ROOT}/docs/bug-classification-registry.json)
Bug title and description: the ticket title and full description text
Fix diff summary: a one-line description of what was changed to fix the bug

Classification Procedure

Read each entry in the registry slug list. Each slug has a classification_question that defines the criterion for that category.
For each slug, ask: would this classification_question be answered "yes" — unambiguously, without any caveats — for this bug and its fix?
Select the best-fit slug where the answer is an unqualified "yes".
If multiple slugs qualify, pick the most specific one.
partial match is not a match — if the bug only partially satisfies a slug's question, or the answer requires hedging, that slug does not apply.
If no slug fits without caveats, return uncategorized. A precise classification is better than a guessed one; when uncertain, return uncategorized.

Output Contract

Return exactly one line: the slug string (e.g., scope-drift) or uncategorized.

No explanation
No markdown formatting
No extra whitespace
No JSON wrapper

Examples

scope-drift

uncategorized

Fallback Rules

Return uncategorized when:

No slug in the registry matches the bug without caveats
The fix diff summary does not clearly map to any slug's classification question
Multiple slugs are equally plausible with no way to pick the most specific one
The bug involves a novel failure mode not covered by any existing slug

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.

bug-classifier-haiku is an agent published in the GitHub repository navapbc/digital-service-orchestra (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 38 tokens to every session and 643 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (strips warnings and disclaimers, unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
