Skill Cost Credit Governor

Skill Cost Credit Governor

Use this skill to prevent silent spend escalation across multi-skill workflows.

Workflow

1. Export invocation usage history (CSV/JSON) with timestamp, skill, token, runtime, and optional caller/provider/locality fields.
2. Ingest live local stack accounting whenever loopback evidence is available.
3. Run skill_cost_governor.py analyze for a rolling window.
4. Review anomaly evidence (cost_spike, inefficient_loop, agent_chatter, runtime_p95_high, remote_heavy_when_local_available).
5. Derive explicit chain action (allow, warn, throttle, disable) from anomaly evidence.
6. Apply proposed warn/throttle/disable actions.
7. Persist analysis and policy artifacts for audits.

Analyze Usage

python3 "$CODEX_HOME/skills/skill-cost-credit-governor/scripts/skill_cost_governor.py" analyze \
  --input /path/to/skill-usage.csv \
  --window-days 30 \
  --soft-daily-budget 120 \
  --hard-daily-budget 180 \
  --soft-window-budget 2800 \
  --hard-window-budget 3400 \
  --spike-multiplier 2.0 \

Extract/Enforce Actions

python3 "$CODEX_HOME/skills/skill-cost-credit-governor/scripts/skill_cost_governor.py" decide \
  --analysis-json /tmp/skill-cost-analysis.json \
  --json-out /tmp/skill-cost-policy.json \
  --format table

Use --force-global-action throttle or --force-global-action disable for emergency containment.

Mandatory Chain Gate

Before finalizing skill chains, provide:

• skill_cost_analysis_json=/tmp/skill-cost-analysis.json
• skill_cost_policy_json=/tmp/skill-cost-policy.json
• global_action=<allow|warn|throttle|disable>
• local stack evidence when loopback accounting exists

If this evidence is missing, chain selection is incomplete and must fail closed.

Action Policy Mapping

Map analysis outcomes to deterministic action:

1. allow:
   • no anomaly above threshold,
   • budget posture healthy.
2. warn:
   • isolated cost_spike or mild runtime_p95_high,
   • no persistent loop/chatter pattern.
3. throttle:
   • repeated cost_spike and/or inefficient_loop,
   • sustained budget pressure in current window, or
   • remote-heavy execution even though local displacement value is positive.
4. disable:
   • severe or recurring agent_chatter/loop amplification,
   • hard-budget breach or high-confidence runaway behavior.

Record both global_action and per-skill actions in the policy artifact.

Scope Boundary

Use this skill only for the skill-cost-credit-governor lane and workflow defined in this file and its references.

Do not use this skill for unrelated lanes; route those through $skill-hub and the most specific matching skill.

Loopback

If this lane is unresolved, blocked, or ambiguous:

1. Capture current evidence and failure context.
2. Route back through $skill-hub for chain recalculation.
3. Resume only after the updated chain returns a deterministic next step.
