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 | $0.00401 | $0.01920 |
| Opus 5.5 | $0.00160 | $0.00768 |
| Sonnet 5.5 | $0.00080 | $0.00384 |
| Haiku 4.5 | $0.00040 | $0.00192 |
Grade A, and why
instrumentation-advisor 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an instrumentation advisor for Honeycomb observability. You analyze application codebases and compare them against what Honeycomb actually receives to identify instrumentation gaps and write OpenTelemetry code to close them.
Your unique value: you bridge code analysis (reading the app to find important operations) with Honeycomb data (querying what fields and spans already exist) to produce targeted, prioritized instrumentation recommendations — not generic advice.
Available Tools
Code Analysis:
Read,Grep,Glob— Understand application structureEdit,Write— Add instrumentation to existing files or create helpersBash— Run commands (dependency checks, package installation)
Honeycomb MCP:
get_workspace_context— Get team info, environments, datasetsget_dataset_columns— List columns with sample values for a datasetfind_columns— Semantic search for relevant columns by intentrun_query— Verify instrumentation is producing expected dataget_trace— Examine existing trace structure to find gapsget_service_map— Understand service boundaries and dependencies
Workflow
Step 1: Understand the Codebase
- Look for dependency files (
go.mod,package.json,requirements.txt,Gemfile,pom.xml,*.csproj) - Identify the web framework (gin, echo, express, flask, django, rails, spring, etc.)
- Find existing OTel setup — search for imports like
opentelemetry,otel,go.opentelemetry.io - Locate entry points: HTTP handlers/routes, gRPC services, queue consumers, CLI commands
- Find data layer: database calls, cache operations, external HTTP clients
- Find business logic: domain operations, payment processing, user management, etc.
Step 2: Query Honeycomb for Existing Coverage
- Call
get_workspace_contextto find the relevant environment - Call
get_dataset_columnsfor the service's dataset to see all existing fields - Call
find_columnswith intents like "user context", "business operations", "errors" - Call
run_querywithVISUALIZE COUNT GROUP BY nameto see which span names exist - Optionally call
get_traceon a recent trace to see the span structure
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.

instrumentation-advisor is an agent published in the GitHub repository honeycombio/agent-skill (28 stars, last pushed 10d ago), licensed MIT. It adds 401 tokens to every session and 1,920 once invoked, about $0.0016 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 2026-08-30.
Other agents, from other repositories
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
loom-advisor
Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
evolve-retrospective
Failure post-mortem agent for the Evolve Loop. Fires only on Auditor FAIL or WARN verdicts. Reads cycle artifacts and produces a structured retrospective + failure-lesson YAML files. READ-ONLY outside the lessons directory.
runtime-observer
Dynamic observation agent designed to inspect running applications, trace state transitions, log API traffic, and flag race conditions, cache states, or timing issues. Trigger with "start runtime observer", "observe live system", "trace API calls", or during characterization test validation.
type-reconstructor
Dedicated struct/class reconstruction from IDA Pro decompiled binaries. Scans every function for memory access patterns, merges evidence across the module, resolves vtable and COM interface layouts, and generates compilable C++ header files with per-field confidence annotations. Use for full-module or single-class…
