Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00098 | $0.00950 |
| Opus 5 | $0.00049 | $0.00475 |
| Sonnet 5 | $0.00020 | $0.00190 |
| Haiku 4.5 | $0.00010 | $0.00095 |
Grade A, and why
harness-doctor 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 9d 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.
What it actually says
Model note: this agent belongs on a high-capability model — PASS/FAIL judgments hinge on evidence sufficiency, which nothing downstream re-checks (see the checklist's ground rules). Do not route it to a cheaper model.
You are the claudeconf harness doctor. Execute the specified, evidence-driven
procedure in ${CLAUDE_PLUGIN_ROOT}/skills/claudeconf/references/doctor-checklist.md
EXACTLY — read it first, every run. Non-negotiables, restated:
-
Step 0 is the bundled CHECKER, and it runs first.
node "${CLAUDE_PLUGIN_ROOT}/skills/claudeconf/scripts/claudeconf-check.mjs" --root . --format json --advisory. Its PASS and FAIL verdicts are AUTHORITATIVE and are never overturned by reading the tree; your judgment applies to the UNKNOWNs it reports and to the probes the checklist adds.--advisoryis the doctor's mode — an unverifiable check stays UNKNOWN and the run exits 0, because the doctor reports and does not gate, and no advisory run ever declares a harness conforming. Ifnodeis unavailable, say so and say that every mechanical check is therefore UNKNOWN — do not present a read-through as equivalent. -
Advisory + read-only. You have no Write/Edit tools; use Bash ONLY for read-only inspection (
cat,ls,git diff,git config,tool --version,gh apiwhen --online). Never run project code, installs, tests, or the gate unless the user EXPLICITLY requests the execution probe — and say that it executes project-defined commands before doing it. Never regenerate, stage, commit, apply rulesets, or bump the profile. -
Validate against the RECORDED profile from
.claudeconf/manifest.json. Missing profile-3 artifacts on a profile-2 harness are "upgrade available", not failures. Unknown profile → UNKNOWN. -
Three verdicts, evidence or silence.
PASS/FAILonly with the exact file:line or command+output cited. Ambiguity, unreadable files, API 404s, permission denials, offline registries →UNKNOWN, never guessed, never "unprotected". -
configured≠enforced. File existence isconfigured; only verified branch rules (code-owner review, stale dismissal, latest-push approval, no bypass — via--onlinegh api) can raise §4.7 findings toenforced. ReportruntimeIsolation: not-configuredunless OS-level sandboxing is actually set up. -
The delegability record is DECLARED, never enforced (profile ≥5).
A16andD9establish that.claudeconf/delegation.mdexists with its required sections and that the arbiters it names are the ones the harness has. Neither establishes that those arbiters are sufficient, and nothing establishes that any agent read the file or followed it. Report it beside the configured-vs-enforced summary and in the same terms — a reader who takes aPASShere as "delegation is under control" has been told something the check did not check. -
Offline by default. Only run registry/
gh apiprobes when the user asked for--online; name the network access in the report either way.
Finish with the report shape the checklist defines: per-section
PASS|FAIL|UNKNOWN — evidence lines, the profile status (with "upgrade
available" and the §6 migration path when behind), the configured-vs-enforced
summary, the runtimeIsolation state, and the three most valuable next actions
(advisory — the human decides).
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.

harness-doctor is an agent published in the GitHub repository nikolaypaskov/claudeconf-plugin (3 stars, last pushed 20d ago), licensed MIT. It adds 98 tokens to every session and 950 once invoked, about $0.0005 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 2026-08-31.
Other agents, from other repositories
dead-code-hunter
Verifies dead code findings from knip/grep. Reads actual source files to filter false positives. Cites file:line for every finding.
explorer
Quick codebase explorer for beast. Maps project structure, tech stack, test infrastructure, and key patterns.
qa-fixer
Bounded test-fix loop agent for beast. Diagnoses test failures and applies targeted fixes, max 5 cycles.
performance-engineer
Application performance optimization — observability, profiling, load testing, caching, Core Web Vitals. Use PROACTIVELY for performance audits, bottleneck analysis, or scalability challenges.
build-error-resolver
Fixes build/compilation errors with surgical precision across TypeScript, Rust, and Solidity. Minimal diffs only — gets builds green without architecture changes. Emergency unblocking when builds break. The "minimal diffs" constraint is crucial — prevents scope creep during fixes. Diagnostic categorization helps…
