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 | $0.00034 | $0.05246 |
| Opus 5 | $0.00017 | $0.02623 |
| Sonnet 5 | $0.00007 | $0.01049 |
| Haiku 4.5 | $0.00003 | $0.00525 |
Grade A, and why
smith-bugfix 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 — 444 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SpecKit Bugfix Workflow
A streamlined alternative to /smith-new for bugs, small changes, and trivial fixes that don't require requirements gathering, planning, or a questions gate. Runs fully autonomously from invocation to merged PR.
Arguments: $ARGUMENTS
Vault Logging
Throughout this action, log significant events to the vault session log. Read the session log path from .smith/vault/.current-session. If the file is missing or the vault is not initialized, skip all logging silently.
Append entries using this format:
### [HH:MM:SS] /smith-bugfix <event>
**User Request:**
> <verbatim user message that triggered this action — capture the exact words the user typed describing the bug or fix needed. For natural language triggers like "fix this", include the preceding context that describes what's broken.>
**Synthesized Input:** <brief summary of the fix being applied>
**Outcome:** <what happened>
**Artifacts:** <files created/modified>
**Systems affected:** <system IDs>
Log at these points:
- On invocation — capture the verbatim user request AND the synthesized bug description
- After branch created — branch name
- After fix applied — files modified, brief description of the fix
- After tests — pass/fail summary
- After specs updated — which specs were updated
- On completion — PR number, merge status, success/failure
Subagent Invocation Logging
Immediately before every Agent tool call in this workflow, append a block to the session log. The Agent tool's return value does not expose subagent_type or model to the parent, so this is the only place that information can be captured.
### [HH:MM:SS] Subagent invoked: <description>
**Type:** <subagent_type or "general">
**Model:** <model override passed to Agent, or "inherited" if none>
After the Agent tool returns, the subagent-vault-writeback.sh hook automatically appends a matching "Subagent completed" block with metrics read from the sidechain transcript — do not duplicate that logging in the skill.
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.

smith-bugfix is a skill published in the GitHub repository ATTCKDigital/smith (52 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 5,246 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 2026-08-30.
