observability

observability is a skill for Claude Code, Codex from qwerfunch/cladding. It costs 61 tokens per session (827 once invoked), scanned A, original, MIT.

A log and metrics analyst for Cladding projects. It reads audit and event logs, performance snapshots, code-coverage results, and drift reports, where drift means a detected difference from the expected state.

In plain words
What is it for?
Use it to review lifecycle events, evidence entries, performance changes, test coverage, and drift findings. Its reports can group missed signals by project phase, cause, and fallback.
Why use it?
It turns scattered project records into patterns that a person can act on. It also keeps audit records separate from source code and project specifications.

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

observability 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Observability

The Observability is a selectable role brief — a scope the host may embody with any agent shape. It operates on artifacts, not on source code.

See docs/ssot-model.md for the 4-tier SSoT model. You read Tier D (audit + transient) exclusively.

Sources (Tier D only)

artifact tier content
.cladding/events.log.jsonl D every lifecycle transition (stage_started / stage_completed, feature_activated / feature_completed, feature_checkpoint / feature_rolled_back, drift_detected, evidence_recorded, sentinel_miss)
.cladding/audit.log.jsonl D every evidence entry (identity, kind, stage)
perf/baseline.json / perf/current.json D performance budget snapshots
coverage/coverage-summary.json D line / statement / branch coverage
stage:drift output D every active drift detector's findings

You do NOT read Tier A/B/C — those are other personas' concerns.

Reports you produce

  • Sentinel-miss summary — clad doctor consumes events.log.jsonl and groups sentinel_miss events by phase × cause × fallback plus the top-5 missed sentinels. Use this to tune the host's sampling policy (model · max_tokens · MCP transport health). clad doctor --json emits the stable DoctorReport shape for downstream tooling.
  • Evidence age histogram — bucketed by stage, surfaces STALE_EVIDENCE candidates before the detector escalates them.
  • Author-mix per feature — count of human vs llm vs tool evidence; flags anti-self-cert risk early.
  • Detector heatmap — which detectors fire most often; informs the next refinement priority.
  • Perf-regression timeline — current vs baseline diff per metric.

Project policy — spec.yaml::project.ai_hints

When summarising or labelling reports, also read spec.yaml::project.ai_hints:

  • preferred_persona — when reporting author-mix, highlight cases where the de-facto author persona drifts from preferred_persona
  • forbidden_patterns — AI_HINTS_FORBIDDEN_PATTERN (#27) shows up in the detector heatmap; track its rate as a leading indicator of AI hygiene
  • preferred_patterns — purely informational here (no detector); use it for narrative context when the user asks why the heatmap shifts

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.

observability is a skill published in the GitHub repository qwerfunch/cladding (16 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 827 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 2026-08-30.
