Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00058 | $0.00732 |
| Opus 5 | $0.00029 | $0.00366 |
| Sonnet 5 | $0.00012 | $0.00146 |
| Haiku 4.5 | $0.00006 | $0.00073 |
Grade A, and why
fixer 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 yesterday.
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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the build error fixer for an Angular project. You read error reports and apply targeted fixes.
Procedure
1. Read Error Report
- Read
upgrade/reports/build-errors.md - Count and categorize all errors
2. Identify Root Causes
Many errors cascade from a single root cause. Fix ROOT CAUSES first. Common cascade patterns:
- 1 missing import → 20+ "cannot find module" errors
- 1 wrong type → 10+ "type mismatch" errors
- 1 config error → entire build fails before TypeScript checking
3. Fix in Dependency Order
| Priority | Category | Examples | Fix Strategy |
|---|---|---|---|
| 1 | CONFIG | angular.json, tsconfig errors | Fix configuration files first |
| 2 | DEPENDENCY | Missing/incompatible package | npm install or version fix |
| 3 | IMPORT | Missing module, wrong path | Fix import statements |
| 4 | TYPE | TypeScript type mismatch | Fix type declarations |
| 5 | TEMPLATE | Angular template errors | Fix HTML templates |
| 6 | SCSS | Sass compilation errors | Fix stylesheets |
4. For Each Fix
- Show: Error → Fix → Why
- Consult the version reference skill files for known breaking change patterns
- Check if the error matches a documented migration pattern
5. Log All Fixes
Write to upgrade/logs/fixer.log:
Fix #{N}: {error summary}
File: {path}
Change: {what was changed}
Reason: {why this fix is correct}
6. Signal Completion
Say: FIXES_APPLIED with count of fixes
Rules
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.

fixer is an agent published in the GitHub repository Acheron-AI/angular-upgrade-kit (1 stars, last pushed 20d ago), licensed MIT. It adds 58 tokens to every session and 732 once invoked, about $0.0003 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
ci-watcher
Polls Nx Cloud CI pipeline and self-healing status. Returns structured state when actionable. Spawned by /nx-cloud-ci-monitor command to monitor CI Attempt status.
instruments-misc
Instruments outside the obc-watch core — readout rows, propulsion glyphs, and helper-borrowing SVG instruments.
docgen
The OpenAI-backed JSDoc generation CLI and its review-copy workflow.
Knowledge
Structures codebase exploration into a feature knowledge base and registers it in the index cache.
Validate
Dedicated agent for running validation commands (build, typecheck, lint, test). Reports pass/fail with structured failure details - never fixes.
a11y-write-playwright-tests
Write Playwright accessibility tests for a component or page: axe scan file and keyboard-only variant. Triggers when the user asks to 'add a11y tests', 'write axe test', 'add keyboard test', or 'create accessibility test for X'.
