Overview

Catalog of this repo's measurement instruments, each with command, current baseline, and interpretation guide. Covers skill size and description budgets, orphan-ref and golden-principles scans, drift gates as signals, coverage pins, and the eval harness. Use when you say `measure this`, `read the drift signal`, `check skill budgets`. Do NOT use to fix what you measure (use `ai-agents-debugging-playbook`) or for evidence standards (use `ai-agents-validation-and-qa`).

ai-agents Diagnostics Toolkit

Measure instead of eyeball. Every instrument below leaves the trees it measures unchanged, turning a vague worry ("are skills getting bloated?", "did generation drift?") into a number you can compare against a baseline; build_all.py --check's one exception, a gitignored audit file outside those trees, is covered below. The Instrument Index gives you, per instrument, the question it answers and the exact command; references/instrument-guides.md gives the healthy and unhealthy reading, the current repo baseline (as of 2026-07-29), and the trap that has already cost someone time.

Vocabulary, defined once: an "instrument" is a script whose output you read, not a gate you must pass. A "drift gate" is a CI check that fails when a generated tree stops matching its canonical source. A "baseline" is the number the instrument reports on a clean checkout of main; you measure your delta against it.

Instrument Index

Instrument	Question it answers	Command (from repo root)
Description budget	How much standing context do skill descriptions cost?	`uv run python ./scripts/skill_description_budget.py`
Skill size	Which SKILL.md files exceed the 300-warn / 500-block line limits?	`uv run python ./scripts/validation/skill_size.py`
Orphan refs	Do specs, evals, and manifests reference entities that no longer exist?	`python3 "${COPILOT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-.claude}}/skills/orphan-ref-validator/scripts/scan.py"`
Golden principles	Where does the repo violate GP-001..GP-005 mechanical rules?	`python3 "${COPILOT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-.claude}}/skills/golden-principles/scripts/scan_principles.py"`
Agent drift	Do generated agent files match their templates?	`uv run python build/generate_agents.py --validate`
Mirror drift	Do the 7 generated mirror trees match `.claude/` canonical sources?	`uv run python build/scripts/build_all.py --check`
Lib drift	Do the lib plugin trees match `scripts/` canonical modules?	`uv run python build/scripts/build_all.py --check`
Coverage	Is changed code actually exercised by tests?	`uv run pytest <tests> --cov=<module> --cov-branch`
Eval A/B	Did a prompt or agent change alter behavior, measurably?	`uv run python ./scripts/eval/eval-prompt-change.py --scenarios <file> --dry-run`
Commit count	Advisory-only signal, not a cap (ADR-099)	`git rev-list --count HEAD ^origin/main`

Process

Phase 1: Pick the instrument

Match the worry to the row in the Instrument Index. Two routing rules:

If you want to...	Go to
Fix the failure an instrument surfaced	`ai-agents-debugging-playbook`
Know what counts as test evidence	`ai-agents-validation-and-qa`
Prove a runtime hypothesis with a probe	`ai-agents-empirical-probe-toolkit`
Regenerate after a drift red	`ai-agents-generation-and-release`
Query agent JSONL event logs	`observability` skill (do not duplicate it)
Get adoption metrics from git history	`metrics` skill (`collect_metrics.py`)

Phase 2: Run it correctly

Run from the repo root. All commands above assume it.
Use uv run python, not bare python3, for anything that imports repo modules (PyYAML lives in the venv; bare python3 gives ModuleNotFoundError: No module named 'yaml').
Every instrument here leaves the owned trees it reads unchanged in the modes shown, build_all.py --check included, but that one is not a no-write run overall: it runs its generators and then restores the owned trees from a snapshot (issue #2440, _snapshot_owned_prefixes and _restore_owned_prefixes in build/scripts/build_all.py), so its log prints Mode: Generate and a nonzero Written: count even though the owned trees end the run as they started, and separately write_audit creates or overwrites build/audit/GENERATION-AUDIT.md on every invocation, a path outside the snapshot that restore never touches. It is gitignored (/build/audit/), which is why git status --porcelain still comes back clean over the owned trees. Confirm with git status --porcelain if suspicious, and see the trap in the Drift gates section of references/instrument-guides.md.
Read the exit code, not just the prose. It is the machine signal:

Exit code	Convention (ADR-035 / AGENTS.md)	Exceptions
0	Healthy or within limits	`skill_size.py` prints FAIL lines but exits 0 unless `--ci`
1	Logic finding (budget exceeded, CRITICAL_FAIL, over limit in `--ci`)
2	Config error (bad path, bad args); for `build_all.py --check`, staleness, a path under `OWNED_PREFIXES` that cannot be read or redirects (symlink or junction) or holds a nested git repository, or a generator writing under `.claude/` (REQ-003-010). Read stderr: only the staleness producer is fixed by regenerating
3	External failure; for `build_all.py --check`, git state unreadable (launch failure, timeout, nonzero exit), not fixed by regenerating
10	Violations found	`scan_principles.py` only

Phase 3: Read the number against the baseline

Compare against the "Current baseline" entry in each guide in references/instrument-guides.md. The repo baseline is NOT all green: golden principles is red on main today (exit 10, 109 errors), and the description budget is over its 8000-token gate at ~10235 (exit 1 in gate mode). What matters for your change is the delta: your PR should add zero new findings, and should not grow a budget without saying so.

Phase 4: Act on the reading

Green and unchanged: move on. Red where the baseline was green: your change caused it; triage via ai-agents-debugging-playbook. Red where the baseline was already red: not yours to fix silently, but flag it (see-something-say-something) and keep your delta clean.

Instrument Guides

Per-instrument detail (the exact command variants, the current repo baseline as of 2026-07-29, the healthy and unhealthy readings, and the trap each instrument has already cost someone) lives in references/instrument-guides.md. Pick the instrument from the index above, then consult its section. That reference also carries the Current Baselines Summary snapshot.

Anti-Patterns

Anti-pattern	Why it burns you
Eyeballing ("the diff looks fine") instead of running the instrument	The 2025-12-15 drift inversion and PR #1887's 0/35 prevented-fix audit both started with confident eyeballs
Treating a red baseline as your failure, or silently "fixing" it repo-wide	Mass edits outside your scope; PR #908's scoped-lint lesson. Flag it, keep your delta clean
Quoting the chars/4 token estimate as an exact cost	It is a trend instrument, by design
Reading `Mode: Generate` in `--check` output as proof the gate wrote files	#2440 snapshot/restore makes it read-only; check `git status --porcelain`
Fixing scanner findings inside generated trees	Regenerated over on the next build; fix the `.claude/` canonical source
`--cov=<file path>` or an uncalibrated `--cov-fail-under` pin	0% "Module never imported" (#2063) or a 63% false trip (#1963)
Running a paid eval without `--dry-run` and a written prediction first	Spend with no falsifiable claim; see `ai-agents-research-methodology`
Adding a detector or threshold without replaying it against recent real PRs	#1989 M4 shipped a threshold of 6 in a repo whose max was 4; it could never fire

Verification

Before citing any number from this toolkit in a PR, session log, or decision:

The command was run from repo root with uv run python and the exit code was captured, not just the prose output.
The reading was compared against the baselines in references/instrument-guides.md, and what you report is the DELTA your change introduces.
Any red you did not cause is flagged in your PR description, not silently fixed or silently ignored.
Volatile numbers you quote are date-stamped, the way this file stamps its own.

Provenance and Maintenance

Written 2026-07-02; every baseline in this skill re-measured 2026-07-29 by running each instrument on this checkout. Under the current squash-only policy, PR-branch SHAs do not land on main. One merge commit predates that policy (0f13c85ab, PR #1, 2025-12-13), so verify ancestry instead of assuming. Do not use git log to re-derive any of this.

Sources: scripts/skill_description_budget.py (docstring, issue #2794), scripts/validation/skill_size.py (limits, issue #676), .claude/skills/orphan-ref-validator/scripts/scan.py:234-235 and patterns.py:63,89 (directives), .claude/skills/golden-principles/scripts/scan_principles.py (rules, exit 10 while baseline is red), build/scripts/build_all.py:1057-1058,1465 (read-only check), .github/workflows/pytest.yml:427-455 (coverage pins), scripts/eval/eval-prompt-change.py --help, scripts/eval/_anthropic_api.py (harness), AGENTS.md:24 (commit cap), .claude/skills/skillforge/scripts/_constants.py:65 (1024 cap, canonical); validate-skill.py:250-251 (enforces it).

Re-verify one-liners for every volatile fact:

Fact	Re-verify with
Description budget totals	`uv run python ./scripts/skill_description_budget.py`
Skill size FAIL list	`uv run python ./scripts/validation/skill_size.py`
Orphan-ref verdict and counts	`python3 "${COPILOT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-.claude}}/skills/orphan-ref-validator/scripts/scan.py"` (read last line)
Golden-principles totals	`python3 "${COPILOT_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-.claude}}/skills/golden-principles/scripts/scan_principles.py"` (read last line, expect exit 10 while baseline is red)
Drift gates green	run all three gate commands from the Drift gates section of `references/instrument-guides.md`
Push guards and guard-maturity classifier removed under ADR-084	`ls .claude/hooks/PreToolUse/` (no `push_guard_base.py` or `invoke_*_guard.py` should be present) and `ls -d .claude/skills/guard-maturity` (expect "No such file or directory"; issue #5154)
Coverage pin forms	`grep -n "cov-fail-under" .github/workflows/pytest.yml`
Commit count	`git rev-list --count HEAD ^origin/main`

When a baseline here goes stale (a red turns green or a number moves), update the table in the same PR that moved it, or flag the stale row to the owner in the PR body.

# ai-agents Diagnostics Toolkit

<!-- vendor-portability: contributor-facing knowledge pack for the rjmurillo/ai-agents repo itself; intentionally references upstream paths (.agents/, .claude/, .claude/lib, scripts/, build/, build/audit/GENERATION-AUDIT.md) because its audience is repo contributors, not plugin consumers (issue #2050) -->
Measure instead of eyeball. Every instrument below leaves the trees it measures unchanged, turning a vague worry ("are skills getting bloated?", "did generation drift?") into a number you can compare against a baseline; `build_all.py --check`'s one exception, a gitignored audit file outside those trees, is covered below.

Green and unchanged: move on. Red where the baseline was green: your change caused it; triage via `ai-agents-debugging-playbook`. Red where the baseline was already red: not yours to fix silently, but flag it (see-something-say-something) and keep your delta clean.

## Instrument Guides
