temper

temper is a skill for Claude Code from alphabravo-oss/guild. It costs 55 tokens per session (6,205 once invoked), scanned A, original, MIT.

A focused software audit that examines individual functions, pages, and user flows after broader checks are complete.

In plain words
What is it for?
Use it to investigate specific functions, pages, and flows for defects in an existing codebase.
Why use it?
Broad reviews can miss bugs hidden inside small parts of an application. It narrows the inspection to test whether each part actually works.

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.

Security

Grade A, and why

temper 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 1mo 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 — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Foundry integration: This skill's methodology is used as F5 TEMPER in Foundry runs invoked with --temper. When invoked by Foundry, temper domains and probe results are written to foundry-archive/{run}/temper/.

Temper — Micro-Domain Deep Audit

Temper activates after F4 ASSAY terminates. What terminates ASSAY is the tier-aware gates, not a count of every finding ever filed: ASSAY passes when no LIVE defect and no unknown-tier defect is open, and an open backlog of the non-blocking tiers, LATENT and HARDENING alike, does not hold it shut — the same rule that ends temper itself, stated once more under When the sweep ends below. Broad audits miss things because they look at too much at once. Temper zooms into the smallest units of functionality and proves they work — or proves they don't.

Mindset: Bug Hunter, Not Reviewer

Your job is to FIND what's broken. Assume every function has a bug until you prove otherwise by reading the body line by line. If you finish with zero findings, you failed — re-read the 5 most complex functions and run the checklist again.


Phase C0: ROSTER — read the recorded candidates BEFORE anything else

Your first tool call is Foundry-Observations(classification="TEMPER_CANDIDATE"). Those records are the probe ideas the PROVE stream had at INSPECT and was forbidden to file: on a run with --temper set, an INSPECT defect must cite the matrix row whose stated behaviour failed, and every off-row hunch is recorded as a candidate instead of spent as a GRIND cycle. TEMPER is the phase those hunches were being saved FOR. Read them before you build anything, because a candidate you never read is a probe the run paid to think of and then threw away.

Your roster is the open candidates UNIONED with your own micro-domains, never one or the other. Phase C1 below discovers domains from the filesystem and stays spec-blind; this read does not break that, and the reason is mechanical rather than a promise: a TEMPER_CANDIDATE observation carries no spec_ref and no requirement id at all — Foundry-Observation refuses one that does, reading any spec_ref as a spec-required-behaviour claim by construction — so a candidate tells you a place to look and nothing about what the spec says should be there. Walk the filesystem in C1 without narrowing it to the candidate list, then add every open candidate to the domains that walk produced.

temper is a skill published in the GitHub repository alphabravo-oss/guild (2 stars, last pushed 11d ago), licensed MIT. It adds 55 tokens to every session and 6,205 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-04.
