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 5.1 | $0.00048 | $0.02953 |
| Opus 5.5 | $0.00019 | $0.01181 |
| Sonnet 5.5 | $0.00010 | $0.00591 |
| Haiku 4.5 | $0.00005 | $0.00295 |
Grade A, and why
reproduce-and-fix-issues 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.
This is a copy
100% identical to reproduce-and-fix-issues — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reproduce and fix issues
Wait for a trusted triage marker in the source thread. Reproduce the exact symptom through the target app's real UI. Verify an existing fix when one exists. Attempt a bounded fix only after a confirmed repro.
Load the external Benny configuration supplied by the automation. If the config, required actions, control adapter, or completed feature map is missing, fail closed.
Hard safety rules
- Freeze the source channel and root thread coordinates before doing any work.
- Never post a root message in the source channel.
- Preflight the source parent before every source-thread post.
- The coordinator is the only Slack poster.
- Delegated analysis workers are read-only and return findings or media notes.
- A fix-phase code worker may edit only when its environment provably excludes Slack credentials and every Slack write action. Otherwise the coordinator edits.
- Every child prompt must explicitly forbid
SendSlackMessage,PostToSlack,chat.postMessage, and all other Slack writes. - Never give a child a Slack token, posting instructions, source coordinates for posting, or permission to report externally.
- If a child needs Slack write access to run, do not launch it.
- Utility bots are evidence sources. They do not own the fix unless a person explicitly delegated the fix to them.
- The exact discriminating symptom must appear twice through real UI interaction.
- State inspection may confirm an observation. It must not inject or force the symptom.
- No confirmed repro means no authored fix.
- Existing pull requests or commits switch the run to verify mode. Do not author over them.
- Use
github.compull request links. - Keep captures, recordings, logs, and tokens out of source control.
- Use pstack's
principle-guard-the-context-windowfor delegated analysis. - Apply pstack's
principle-sequence-verifiable-units,principle-fix-root-causes, andprinciple-prove-it-worksthrough repro, fix, and verification.

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

reproduce-and-fix-issues is a skill published in the GitHub repository minghinmatthewlam/agent-guards (47 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 2,953 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to reproduce-and-fix-issues, differing in 0 lines, and is treated as a copy.
